DESCRIPTION OF THE PREFERRED EMBODIMENTS

(40) Referring to the drawings in particular, the present invention pertains to a transporting device (5) for compressed pressed bales (25). It pertains, furthermore, to a packaging technology, to a packaging device (18) for pressed bales (25) with a transporting device (5), to a packaging station (19) as well as to a bale press plant (1) with at least one bale press (2) and with a transporting device (5). The bale press (2) may be a one-part or multipart bale press and have one or more presses (3, 4) for compressing the bales.

(41) FIG. 1 shows a bale press plant (1) with a bale press (2) and with a transporting device (5). The bale press (2) has a prepress (3) and a finishing press (4) in this exemplary embodiment. The prepress (3) can be charged via a pressing material feed unit (23). The charging may preferably take place batchwise, the bale material to be pressed being inserted in a press box (17) interactively, is amassed there and precompressed between two pressure rams (11, 12) to form a pressed bale (25). As an alternative, charging may take place in any other desired manner.

(42) The material to be pressed may preferably consist of fibers. These may be especially fibers made of rayon, polyester, natural fibers or recycled fibers. As an alternative, other fibers or other materials may be compressed into pressed bales as desired, for example, straw or other plant parts, domestic waste or wastes or compressible metal parts.

(43) The bale press (2) has a finishing press (4) with an upper pressure ram (13) and with a lower pressure ram (14) in the exemplary embodiment. A precompressed pressed bale (25) can be placed into the finishing press and subjected to final compression under high pressure to form a highly compressed pressed bale (25). Such a highly compressed pressed bale may be subsequently provided, e.g., with a fixing means (31), e.g., a strapping, and discharged via a conveyor (24) or a bale removal means.

(44) The bale press plant (1) has a transporting device (5). The transporting device (5) is provided with a bale receptacle (6) for retaining a pressed bale (25), e.g., a precompressed pressed bale (25), with the pressed bale being held on two opposite sides. These are, e.g., the pressure sides, via which the pressed bale (25) is subjected to pressure and compressed. The bale receptacle (6) has a plurality of elongated, for example, rod-shaped or beam-shaped support elements (20), which are located at spaced locations from one another, on the sides intended for retaining the pressed bale (25). Such a transporting device (5) with a bale receptacle (6) is shown in FIG. 2. The bale receptacle (6) being shown is designed, for example, as a supporting fork.

(45) The support elements (20) are arranged on a basic carrier (21) of the bale receptacle (6), e.g., on the mutually opposite side edges thereof. The support elements (20) and the basic carrier (21) may be preferably designed as clamps or forks, and an essentially cuboid receiving area is formed between the support elements and the basic carrier. In particular, the support elements (20) may be arranged in a regular pattern in the manner of fork tines. An upper set and a lower set of support elements (20) may be formed especially at the bale receptacle (6). The support elements (20) within one set may preferably have an identical design and be arranged in parallel to one another. Furthermore, they may be arranged at uniformly spaced locations from one another. The number, size and arrangement of the support elements (20) may vary depending on the size of the pressed bale (25).

(46) As is illustrated as an example in FIG. 2, the shape and arrangement of the support elements (20) may preferably correspond to recesses (16) in the active surface (15) of at least one pressure ram (11, 12, 13, 14) of a bale press (2, 3, 4). The support elements (20) can dip, as a result, into the recesses (16). The support elements (20) may have the same distance from each other as do the recesses (16) in the pressure rams (11, 12, 13, 14). In particular, the pressure rams (11, 12, 13, 14) may preferably have recesses arranged in the same manner and with correspondingly identical shape. The width of a support element is preferably smaller than the opening width of a recess (16), so that the support elements (20) can be inserted into the recesses (16) in the direction of their longitudinal axis. The support elements (20) and the recesses (16) are preferably stretched in an elongated form and straight.

(47) The basic carrier (21) and the support elements (20) may have a layered construction. As is shown in FIG. 2, one layer each may be formed by a clamp- or fork-shaped sheet metal or plate part, which now forms an upper support element (20) and a lower support element (20) as well as a part of the basic carrier (21). A plurality of such sheet metal or plate parts may be connected with one another in parallel to one another and at spaced locations from one another, and the support elements (20) form the bale receptacle (6) together with the basic carrier (21). As an alternative, the bale receptacle may have any other design as desired.

(48) The bale receptacle (6) is preferably mounted rotatably on a bracket (9). The bracket (9) may be part of a manipulator (7) or connected to a manipulator (7). A moving device is formed for the bale receptacle (6) via the manipulator (7) and possibly the bracket (9). The manipulator (7) is preferably designed to move a bale receptacle (6) between at least one prepress (3) and a finishing press (4). As an alternative or in addition, the manipulator (7) may be designed to move the bale receptacle (6) to a packaging system (18) and/or to a packaging station (19).

(49) The bale receptacle (6) and the manipulator (7) may have any desired design. FIG. 5 shows an exemplary embodiment of a bale press (2) with a prepress (3) and with a finishing press (4), wherein a manipulator (7) is arranged in the form of a cross slide manipulator between a prepress (3) and a finishing press (4). The bale receptacle (6) is connected with the manipulator (7) via a bracket (9) and can be driven and positioned by rotatory motion about a vertical axis and can be driven and positioned by translator motion along a vertical axis. In an alternative exemplary embodiment according to FIG. 6, a bale receptacle (6) is mounted in a bracket (9) having an alternative design and can be driven and positioned by rotatory motion about a horizontal axis. A manipulator (7) may also be designed as a multiaxial industrial robot with, for example, four, five, six or seven axes of motion.

(50) FIG. 4 shows another exemplary embodiment of a bale press plant (1). The bale press plant comprises here a bale press (2) with a first prepress (3) and with a second prepress (3) as well as a finishing press (4). A manipulator (7) is designed as a biaxial cross slide manipulator with two vertical axes of motion and is arranged in an area between the prepresses (3, 3) and the finishing press (4). A bale receptacle (6), which can be moved between the prepresses (3, 3) and the finishing press (4), is arranged at the manipulator (7). The bale receptacle (6) is connected here with the manipulator (7) via a bracket (9) and can be driven and positioned by rotatory motion about a vertical axis and can be optionally driven and positioned by translator motion along a vertical axis.

(51) A bale press plant (1) may preferably have a packaging system (18). The packaging system (18) is designed to apply a film packaging (32) to a precompressed pressed bale (25). It has means (30) for forming a stretched film web (28), especially a film curtain (28). The packaging system (18) may have, in particular, a film storage means (29), for example, a film coil, and a film gripper (30). It is preferably arranged on a feed side of a finishing press (4). As an alternative, a packaging system (18) may be arranged at any other desired location. A bale press plant (1) may also be designed without a packaging system (18).

(52) FIG. 3 shows a bale press plant (1) with a preferred embodiment of a packaging system (18) in a lateral view. The packaging system (18) have a film coil (29) here, which is arranged in an area above the feed opening of a finishing press (4). A film can be pulled downwardly from the film coil (29) to form a stretched film web, especially a film curtain (28), by a film gripper (30). The film curtain (28) may preferably now cover the feed opening of the finishing press (4) with a stretched film web.

(53) The packaging system (18) may have a transporting device (5) with a movable bale receptacle (6) for receiving a precompressed pressed bale (25) or cooperate with such a transporting device (5). The transporting device (5) may have any desired design. It may be, in particular, a transporting device (5) proposed according to the present invention.

(54) The bale receptacle (6) may be able to be moved through a stretched film web, especially through a film curtain (28). The film web (28) may be fed preferably at at least one end, for example, by pulling off the film from the foil storage means (29). The film web (28) forms a loop around the bale receptacle (6) and the pressed bale (25) being held therein while the bale receptacle (6) is being passed through the film curtain. The bale receptacle (6) and the pressed bale (25) can be preferably enveloped by the film on three sides in this manner.

(55) The transporting device may preferably have a push-out plate (8). The push-out plate may have any desired design. A preferred embodiment of a push-out device is shown, for example, in FIG. 2. It has a push-out plate, which is directed essentially at right angles to the longitudinal axis of the support elements (20) of the bale receptacle (6) and can come into contact with a rear side of a pressed bale (25) inserted into the bale receptacle (6). The pushing plate may be preferably able to be moved by translator motion, driven and pushed out in parallel to the longitudinal axis of the support elements (20). By actuating the push-out device (8), a pressed bale (25) can be pushed out of the bale receptacle (60. The pressed bale (25) can now slide along the surfaces of the support elements (20) pointing towards the inside of the bale receptacle (6). The push-out device (8) may preferably cover the entire free surface area between the upper and lower support elements (20) and hence possibly the entire surface of a rear side of a pressed bale (25). As an alternative, a push-out device (8) may have any other desired design.

(56) FIGS. 7 through 21 show the mode of operation of a preferred embodiment of a bale press plant (1). The mode of operation of a transporting device (5), of a packaging system (18) and of a bale press (2, 3, 4) are shown combined. However, the corresponding process steps may also be carried out independently from one another. In particular, a bale press plant (1) may also be designed without packaging system (18).

(57) The bale press plant (1) shown in FIGS. 7 through 21 has a bale press (2) with a prepress (3) and with a finishing press (4). A transporting device (5), which has a bale receptacle (6) movable via a multiaxial manipulator (7), is arranged between the prepress (3) and the finishing press (4).

(58) The transporting device (5) may have a fixing device (10) for the pressed bale (25), e.g., a strapping device. The strapping device (10) comprises a deflecting means (37) with one or more strapping channels for guiding a strapping (31). The deflecting means (37) is arranged on a basic carrier (21) of the bale receptacle (6). It is arranged here on the rear side for the clamp-like opening of the bale receptacle (6). As an alternative, a strapping device (10) may be arranged at the transporting device (5) in another manner, for example, as a separately movable unit without connection to the bale receptacle (6).

(59) In the exemplary embodiment according to FIGS. 7 through 21, the bale receptacle (6) has two sets of upper and lower support elements (20). The support elements (20) of one set are always arranged in parallel to one another and at spaced locations from one another. The arrangement of the upper support elements (20) and of the lower support elements (20) is essentially identical. The arrangement of the support elements (20) always corresponds to recesses (16) in the active surfaces (15) of upper pressure rams (11, 13) and lower pressure rams (12, 14) of the prepress (3) and of the finishing press (4).

(60) The prepress (3) has a press box (17) with a press box door (26). Material to be pressed is amassed, optionally batchwise, within the press box (17) and precompressed to a pressed bale (25). A lower pressure ram (12) is arranged on the underside in the press box. An upper pressure ram (11) can be movably guided in the press box. The compressing force of the pressure rams (11, 12) is directed here essentially vertically, and the side walls of the press box (17) apply essentially a supporting force only. When the press box door (26) is opened, a pressed bale (25) formed and being held between the upper pressure ram (11) and the lower pressure ram (12) of the prepress can be accessible from the opened side.

(61) As is shown in FIG. 8, the bale receptacle (6) can be moved into the press box (17). This preferably happens with the pressure rams (11, 12) brought together, while the support elements (20) of the bale receptacle (6) are being inserted into the recesses (16) of the pressure rams (11, 12). Due to the insertion of the bale receptacle (6) into the press box (17), the bale receptacle (6) preferably encloses the pressed bale (25) on the pressure sides thereof, here on the upper side and the underside, with the support elements (20). The support elements (20), especially the upper and lower sets of support elements (20), may have a somewhat greater distance between them than the height of the pressed bale. The bale receptacle (6) can thus be inserted with the support elements (20) into the press box (17) in an extensively or entirely contact-free manner. FIG. 9 shows a fully inserted position of the bale receptacle (6) in the press box (17).

(62) The upper pressure ram (11) of the prepress (3) can be preferably raised upward or pulled off in the inserted position of the bale receptacle (6). The precompressed pressed bale (25) is relieved now in its vertical direction and can expand in the vertical direction due to its elastic prestress. The precompressed pressed bale (25) now comes into contact with the support elements (20) of the bale receptacle (6). The bale receptacle (6) may optionally be raised slightly simultaneously with the relieving motion of the upper pressure ram (11), so that the precompressed pressed bale (25) is lifted off on its underside from the lower pressure ram (12). As an alternative, another combination of the motion of the upper and/or lower pressure rams (11, 12) and/or of the bale receptacle (6) may take place. In particular, the bale receptacle may perform, as an alternative or in addition, a slight tilting motion, during which the free ends of the lower support elements (20) are raised, so that the pressed bale (25) is entrained in the direction of the basic carrier (21) of the bale receptacle (6). Holding of the pressed bale (25) in the bale receptacle (6) can be additionally supported in this manner.

(63) The precompressed pressed bale (25) is held especially by its internal stress after its expansion in the bale receptacle (6) between the support elements (20). When the bale receptacle (6) is pulled out of the press box (17), the precompressed pressed bale (25) can thus be moved along and removed from the press box (17).

(64) As is shown in FIGS. 10ff, the bale receptacle (6) can preferably be moved by the manipulator (7) from the prepress (3) to the finishing press (4). The bale receptacle (6) can be optionally pivoted or tilted now about a vertically or horizontally directed axis of rotation, as this is also shown in the exemplary embodiments of a bale press according to FIGS. 4 and 5.

(65) The bale press plant (1) may have a packaging system (18), which is preferably arranged in front of a feed opening of the finishing press (4). The packaging system (18) has a film storage means (29), from which a film web can be stretched preferably in the form of a film curtain (28) in front of the feed opening of the finishing press (4). FIG. 10 shows, for example, a packaging system (18) with a vertically displaceable means (30) for stretching a film web (28). The means (30) may be especially a film gripper, which picks up a free end of the film from the film storage means (29) and pulls it downward, while the film forms a film curtain (28) shown in FIG. 11 in front of the feed opening of the finishing press (4).

(66) The bale receptacle (6) can be inserted into the finishing press (4) through the film curtain (28). The film curtain (28) can be held now at the lower end, while film material can be fed from the upper end, for example, by pulling off from the film storage means (29). As an alternative, the stretching and feeding of the film material may take place in another suitable manner.

(67) While the bale receptacle (6) is being pushed in and the bale receptacle (6) is moving now through the film curtain (28), the film material slides around the bale receptacle (6) and the pressed bale being held therein. The film now forms a loop and preferably covers an area of the upper side and underside of the bale receptacle (6) as well as a front face side of the pressed bale (25). It may be especially advantageous if the distance between the upper pressure ram (13) and the lower pressure ram (14) of the finishing press (4) is greater during the pushing in of the bale receptacle (6) than the vertical outer distance of the support elements (20). A free space, in which the film of the film curtain (28) can slide unhindered, can be preferably formed in this manner both between the upper support elements (20) and the upper pressure ram (13) and between the lower support elements (20) and the lower pressure ram (14).

(68) Sliding of the film around the bale receptacle (6) and the pressure rams (13, 14) can be additionally facilitated by device technology. For example, sliding edges (22) may be arranged at the free ends of the support elements (20) to facilitate the sliding around of a film (28). Corresponding sliding edges may likewise be provided on the pressure rams (13, 14) of the finishing press (4). Replacement means, with which sliding edges (22) can be replaced by other means facilitating the sliding of a film, for example, deflecting rollers or anti-adhesion coatings, etc., are known to the person skilled in the art.

(69) FIG. 13 shows a bale receptacle (6) with a pressed bale (25) being held therein in the fully withdrawn position in the finishing press (4). The film web (28) runs now, starting from a film storage means (29), horizontally downwardly to a front sliding edge of the upper pressure ram (13), where it runs inwardly into the space of the finishing press (4) and is led in a free space between the upper support elements (20). Over the further course, the film web (18) then runs around the front side of the pressed bale (25) pointing toward the discharge side of the finishing press and is then led out in a free space between the lower support elements (20) and the active surface (15) of the lower pressure ram (14) to the front side. The film web (28) is held at the lower end by the film gripper (30). The film now forms a loop, which corresponds essentially to the horizontal width of the pressed bale (25) and encloses the upper side, a front side and the underside of the pressed bale (25) as well as the support elements (20) and has an upper free end and a lower free end.

(70) As is shown in FIGS. 13 through 15, the bale receptacle (6) can be preferably moved out of the finishing press (4), while the pressed bale (25) remains in the finishing press (4). The bale receptacle (6) can be pulled out of the finishing press (4) while a push-out device (8) of the transporting device (5) is actuated to compensate the removing motion, so that the push-out device (8) supportingly holds the pressed bale (25) in the finishing press (4). The push-out device (8) may have any desired design here. It may preferably have a push-out plate, which can be extended relative to the bale receptacle (6) in the longitudinal direction of the support elements (20) and supports a rear side of the pressed bale (25).

(71) The removal of the pressed bale (25) can be brought about entirely by the push-out device (8), and a holding force is optionally overcome between the upper side and the underside of the pressed bale (25) and the respective upper and lower support elements (20) of the bale receptacle (6). As an alternative or in addition, the pressed bale (25) can be picked up from the finishing press (4) and held with a limited pressing pressure before or during the removal of the bale receptacle (6) between the upper pressure ram (13) and the lower pressure ram (14). For example, the upper pressure ram (13) can be lowered with the bale receptacle (6) pushed in, and the recesses (16) in the active surface (15) of the upper pressure ram (13) leave a free space for the upper support elements (20) of the bale receptacle (6). As an alternative or in addition, the bale receptacle (6) can be lowered at the same time downwardly, and the lower support elements (20) dip into recesses (16) of the lower pressure ram (14).

(72) The pressed bale (25) can thus be picked up clampingly between the upper pressure ram (13) and the lower ram (14). The pressure rams (13, 14) can possibly be fed to the extent that the pressed bale (25) is compressed and separates on the upper side and/or underside from the support elements (20) of the bale receptacle (6). As a result, the pressed bale (25) can be released from the bale receptacle (6), so that the holding force between the support elements (20) and the pressed bale (25) is extensively eliminated. As an alternative, the feed motion of the pressure rams (13, 14) for picking up the pressed bale (25) may take place to the extent that the holding force between the pressed bale (25) and the support elements (20) of the bale receptacle (6) is reduced. The pressed bale (25) fully or partially separated from the holding force between the support elements (20) can thus remain positioned more easily in the finishing press (4), while the bale receptacle (6) is being removed. As an alternative or in addition, the push-out device (8) can hold the pressed bale (25) in position in a supporting manner. Finally, it is possible to tilt the bale receptacle (6) from the finishing press (4) before or during the removal from the finishing press (4), so that a gradient directed toward the finishing press (4), which supports the pushing out of the pressed bale (25), is created via the support elements (20).

(73) FIGS. 24 through 26 show an example of how a film web (28) can extend in the cross section between an upper pressure ram (13) of the finishing press (4) and a bale receptacle (6) with a pressed bale (25) received therein. FIG. 24 illustrates a preferred relative positioning of the pressure ram (13) and support elements (20) during the insertion of the bale receptacle (6) into the finishing press (4). A free space, in which the film web (28) can slide freely, is formed here between the active surface (15) of the pressure ram (13) and the top edge of the upper support elements (20).

(74) FIG. 25 shows a positioning of the pressure ram (13) while the active surface (15) is partly in contact with the pressed bale (25). The pressed bale (25) may be partially compressed by the pressure ram (13), as a result of which the elastic holding force between the pressed bale (25) and the support elements (20) is reduced. The film web (28) can be contacted on both sides in such a case in the area of the active surface (15) between the pressure ram (13) and the pressed bale (25). However, the film web (28) is not contacted on both sides between the support elements (20) and the pressure ram (13), but it lies on the outer surfaces of the support elements (20) on one side only. The bale receptacle (6) with the support elements (20) can be pulled out in this positioning between the film web (28) and the pressed bale (25) without major shearing forces being transmitted to the film web (28).

(75) When the pressure rams (13) are fed even more to the pressed bale (25), an even greater compression of the pressed bale can take place, and the contact between the support elements (20) and the pressed bale (25) may be possibly eliminated altogether. This is shown in FIG. 26. The bale receptacle (6) can be removed from the finishing press (4) in this positioning, without being in contact with the pressed bale (25) at all, so that no or hardly any shearing forces are consequently transmitted to the pressed bale (25).

(76) The film (28) for packaging the pressed bale (25) may consist of any desired and suitable material, e.g., plastic, metal, composites or the like. The film (28) may be resistant to extension and stretching or may be elastically stretchable. It may preferably have a limited elongation elasticity. In particular, it may be stretchable to such an extent that it is stretched elastically when the support elements (20) dip into the recesses (16) of the pressure rams (13, 14).

(77) As an alternative, a film web (28) may be led over its width with slack and possibly in some areas to form a loop, so that free film material will run into the recesses (16) when the pressure rams (13, 14) are lowered over the support elements (20) of the bale receptacle (6) without being stretched. The film web (28) is preferably also contacted on both sides only in the area of the active surface (15) between the pressure rams (13, 14) and the pressed bale (25) when the pressed bale (25) is picked up in a receiving manner. However, it is not clamped between the pressure rams (13, 14) and the support elements (20), so that the bale receptacle (6) can be removed extensively unhindered.

(78) The pressed bale (25) can be subjected, as is shown in FIG. 16, to final pressing in the finishing press (4) under high press pressure. For example, the upper pressure ram (13) can be lowered now downwardly, while the pressed bale (25) is compressed between the upper and lower pressure rams (13, 14).

(79) As is shown in FIG. 17, a free and, for example, upper end (33) of the film web (28) can be laid around the still open front side of the pressed bale (25) preferably after removal of the bale receptacle (6) from the packaging system (18). The film web (28) may be possibly cut now to a suitable length. The other and, for example, lower free end of the film can be guided correspondingly. The packaging system (18) may preferably have cutting and/or joining means (30) for this, with which the film (28) can be cut into lengths and possibly fitted together, especially welded together, in two or more layers. The cutting and/or joining means (30) may be combined, for example, with the film gripper (30). The film loop laid around a pressed bale (25) on three sides can thus be closed with its free ends to form a film packaging (31) extending around the bale in a closed web.

(80) FIGS. 18 through 20 show a preferred embodiment of a strapping device (10). The transporting device (5) comprises here a deflecting means (37) of the strapping device (10), while a corresponding strapping apparatus (36) of the strapping device (10) is arranged on the rear side of the finishing press (4). As an alternative, the arrangement of the strapping apparatus (36) and deflecting means (37) may be reversed.

(81) The deflecting means (37) is preferably arranged on the basic carrier (21) of the bale receptacle (6). The deflecting means (37) may be designed as a rigid device, which has channels for deflecting a strapping. The deflecting means (37) may preferably be able to be fed via the manipulator (7) to the pressed bale (25) being held in the finishing press and subjected to final pressing. The channels of the deflecting means may correspond to recesses (16) in the pressure rams (13, 14) of the finishing press. A strapping apparatus (36) may be able to be fed on the opposite side of the pressed bale (25). The strapping apparatus (36) is preferably designed to push a strapping strip (31) through a recess (16) in the upper pressure ram (13). The strapping strip is picked up on the opposite side by the deflecting means and deflected downwardly through the channels of the deflecting means (37). The strapping strip (31) is returned there through a recess (16) in the lower pressure ram (14) to the strapping apparatus (36). The strapping apparatus (36) can subsequently fit together, especially weld together, the strapping strip into a ring-shaped strapping (31).

(82) The strapping (31) may be preferably applied to a pressed bale (25) provided with a film packaging (32) on the outside. The strapping (31) is preferably wrapped around the pressed bale (25) in the same direction in which the film packaging (32) is wrapped around. The film packaging (32) can avoid in this manner a direct contact between the pressed bale (25) and the strapping (31). The pressed bale (25) is thus protected from contamination or damage to the material due to the strapping (31). The strapping device (10) may be designed, as is shown in FIGS. 19 and 20, for applying strappings (31) sequentially on the pressed bale (25). As an alternative, the strapping device (10) may be designed for applying a plurality of strappings (31) in parallel. A deflecting means (37) may correspondingly have one channel or a plurality of channels for guiding a strapping, which correspond to one or more recesses (16) on the pressure rams (13, 14).

(83) As an alternative, a strapping or another fixing means may be placed directly on the pressed bale. This may also happen in a separate strapping station.

(84) According to FIG. 21, the pressed bale (25) can be discharged from the finishing press (4) preferably by a tilting device, which removes the pressed bale (25) from the finishing press with the pressure rams (13, 14) opened. The pressed bale (25) can be preferably placed now on a conveyor (24), which ensures the further removal of the pressed bale.

(85) As an alternative or in addition to the packaging device (18), a bale press plant (1) may have a packaging station (19). Such a packaging station is preferably designed to place an additional packaging, which leads to packaging of the pressed bale on all sides, on the pressed bale. In a preferred embodiment, a bale press plant (1) has a packaging device (18) for applying a film packaging enclosing the pressed bale in a ring-shaped manner on four sides. A strapping (31) may preferably be placed around the film packaging. The pressed bale (25) thus prepackaged can be fed to a packaging station (19), which applies an additional packaging. Such an additional packaging may be, for example, a hood packaging, especially one made of a stretchable stretch hood. As an alternative, it may be another additional packaging, for example, in the form of a body belt or a single or double bag packaging.

(86) The application of a stretch hood has several advantages. On the one hand, a stretch hood can be laid over the pressed bale (25) such that it fully covers five sides of the pressed bale, for example, an upper side and the four outsides, while it can be laid additionally elastically around the last side, for example, the underside, with the free hood edge area. The prepackaged pressed bale can be provided as a result with an additional packaging, which leads to coverage of the pressed bale on all sides, in only one fully automated process step. This form of packaging is consequently an especially material-saving solution and can be carried out rapidly.

(87) On the other hand, a hood packaging can be applied to a pressed bale (25) from the top in a simple manner. The pressed bale does not require any special handling. Thus, a hood packaging can be applied directly on a pressed bale (25) being moved on a conveyor (24). To facilitate an elastic placement or wrapping of the hood packaging around the underside of the pressed bale, the pressed bale may possibly be lifted off slightly upwardly from the conveyor.

(88) A tube or hood packaging may advantageously also be applied to a pressed bale (25) being held in a bale receptacle (6). This may preferably happen at a packaging station (19). The packaging station (19) may be provided as an alternative or in addition to a packaging device (18). After packing the pressed bale (25) in a tube or hood packaging, a pressed bale (25) may be fed for any desired further treatment, for example, for final pressing and/or to a fixing means.

(89) FIGS. 22 and 23 show a preferred embodiment of a press box 17 of a prepress (3). The press box (17) is essentially cuboid and its upper side and underside are formed by an upper pressure ram (11) and a lower pressure ram (12), respectively, of the prepress (3).

(90) The press box (17) has a press box door having an L-shaped cross section. The press box door can relieve the pressed bale when opened, while there is relief along both horizontal axes at the same time. A pressed bale (25) can be freed in this manner of external stresses in the horizontal plane when opening the press box (17). The pressed bale (25) is consequently held after opening of the press box door with the L-shaped cross section in the vertical direction only by an external stress exerted by the pressure rams (11, 12). Such a design of the press box facilitates the picking up of the pressed bale by a bale receptacle (6) with the support elements (20). With the press box door (26) opened, the pressed bale (25) is not held by clamping forces in the press box (17), as a result of which the risk of unintended shearing or deformation of the pressed bale (25) is reduced.

(91) The above-described exemplary embodiments, which are also shown in the drawings, may be varied in a variety of ways. The first press (3, 3) may be, e.g., a main press, which carries out the prepressing and final pressing operations together and yields a pressed bale (25) having been subjected to final pressing. The additional press (4) may then possibly be eliminated. In another variant, it may be designed as a repress, which only compresses the pressed bale subjected to final pressing, which is inserted or transferred by the transporting device (5) and the bale receptacle (6), to the extent that the bale receptacle (6) can be relieved of the restoring forces and the bale pressure and can be removed from the pressed bale (25). The fixing device (10) and/or packaging device (18) may have the same design as described above.

(92) It is possible in another variant to design the fixing device (10) in a different way in all the above-mentioned exemplary embodiments. It may also be eliminated as an alternative, if, e.g., the packaging means (28) or the bale packaging assumes the fixing of the pressed bale (25) in the pressed form thereof.

(93) The strapping device (10) shown at the transporting device (5), especially at the bale receptacle (6), may be modified in its design. The deflecting means (37) with the one or more strapping channels may be arranged at the support elements (20) or fork tines. The strapping channels may be integrated in the support elements (20) or arranged laterally at the support elements (20), and they are located at some distance from the bale contact side of the support elements (20) in the second case. The push-out device (8) may be adapted correspondingly and may have, e.g., a multipart design with slots for the passage of the strapping bands.

(94) Further, the fixing device (10) may have a different design embodiment and have a different function. As an alternative, or in addition to the plurality of strapping bands (31) shown, one or more other fixing means may be used, e.g., a wide body belt, clamps or the like. The fixing of the pressed bale may be independent from a packaging, especially a wrapping, of the pressed bale (25). The bale fixing described may take place, e.g., prior to the application of a bale wrapping.

(95) Further, the additional press (4) is not absolutely necessary for fixing the pressed bale (25). Fixing may also take place at the bale receptacle (6).

(96) It is possible, besides, to provide a movable construction of the bale receptacle (6) instead of the rigid and fork-shaped bale receptacle (6) shown and preferred, in which case the mutually opposite support elements (20), especially the sets of support elements (20), are movable relative to one another via slides or the like and are adjustable with a suitable controllable drive. The bale receptacle (6) may have, e.g., a split basic carrier (21) with a set of support elements (20) each at the mutually adjustable parts of the basic carrier. A variant with a one-part basic carrier (21) and at least one adjustable set of support elements (20) arranged thereon is also possible. An adjustment may be provided, e.g., for relieving the bale receptacle (6) and for enlarging the feed opening to facilitate pushing out of the preferably fixed pressed bale (25). In the takeover position for removing the bale from the press (3, 3), the bale receptacle (6) may have a withdrawn configuration, in which it is possibly locked in this position. It now has a rigid form, especially fork shape, and the restoring forces of the pressed bale (25) are absorbed by corresponding guides and preferably positive-locking supports of the adjustable support elements (20) or basic carrier parts. Such a design of the fork makes the arrangement of an additional press (4) possibly dispensable.

(97) The packaging and wrapping technique for the fixed or nonfixed pressed bale (25) may also be modified. The packaging station (19) at an additional press (4) may be eliminated in the exemplary embodiments shown and in the above-mentioned actions. The pressed bale (25), which is possibly fixed at the bale receptacle (6) or the additional press (4), may be fed via a conveyor (24) to a packaging station (19), which is arranged downstream at another location and may have any desired design. This may be, e.g., a hood packaging for stretch films, which widens up a tube or bag with an expandable stretching frame and overturns it over the pressed bale (25), possibly in connection with a gathering means. In addition, any other desired packaging technologies with crossed body belts, wrapping in two or three folded-over films or the like, are possible as well.

(98) Further, the packaging means (28) may also be selected as desired. They may be, e.g., cardboard boxes, crates or the like with relatively rigid walls. In addition, bags or other tube- or web-like packaging materials made of other materials, e.g., textiles, stabilized plastic films or the like, are possible as well.

(99) In addition, in a variant of the exemplary embodiments shown, the packaging technology arranged in the area of the transporting device (5) and possibly at the additional press (4), especially the packaging station (19), may be varied, Instead of the film packaging (32) shown with a plurality of film webs (28), a hood or tube packaging may be used. For example, a film tube open on both sides or a hood open on one side or a bag may also be applied over the pressed bale (25) being held at the bale receptacle (6) with a suitable application means, e.g., the aforementioned displaceable stretching frame with a gathering means that is possibly present. This packaging material may possess elastic elongation properties and cling tightly to the pressed bale (25) after release.

(100) Pressed bales (25) may also be wrapped and packaged airtightly with such or similar packaging technology, in which case a vacuum or reduced pressure is generated in the interior space of the packaging. This may take place due to expansion of the bale and stretching of the wrapping or by drawing off air. The pressed bale (25) is then also fixed by the vacuum or reduced pressure and the higher ambient pressure. A separate fixing means (10) may be eliminated. Such a packaging technology with airtight wrapping and vacuum generation may also be used at another location of the bale press plant and with other, e.g., conventional packaging technology.

(101) FIGS. 27 through 35 as well as 36 through 37 show a packaging technology in which a bale packaging (32) in the form of a tube or hood packaging (28) is applied on a pressed bale (25) by means of an applicator (38). A tube or hood packaging (28) may preferably be manufactured from a tube-shaped film or another suitable tube-shaped packaging material. A hood packaging (28) is essentially bag-shaped. It differs from a tube packaging due to the fact that a hood packaging (28) has a closed side and an open side each, whereas a tube packaging has two open sides.

(102) An applicator (38) may have any desired design. It may have, in particular, shortening means (46). A preferred handling of a tube or hood packaging (28) will be shown below based on the example of a hood packaging (28) closed on one side. A tube packaging with two open sides may be pulled over analogously hereto. The following handling steps are correspondingly analogously applicable to a tube packaging.

(103) FIG. 27 shows as an example an applicator (38), at which four shortening means (46) in the form of shortening fingers are arranged. The shortening means (46) are designed to pick up a packaging means (28) in the above-described and controlled manner and then lay it down again. The packaging means (28) preferably has a regular tube shape in the area of the parts to be picked up by gathering. In particular, a circumferential area or tube-shaped wrapping area of the packaging means may be stored on the shortening means (46) in the shortened form. The shortening means (46) may be designed especially to pick up a hood packaging (28) such that the tube-shaped enveloping sides thereof are pulled up as stored packaging means (39) on shortening fingers and a closed side (40) of the hood packaging (28) is stretched between the free ends of the shortening fingers (46).

(104) A hood packaging (28) may be produced, for example, by cutting off a piece of a suitable length from a tube stock provided in a suitable manner and closing it on one side, for example, by welding. This may be preferably carried out by a hood producing device (not shown) at a packaging station (19). The tube stock may be, e.g., in the form of a coil. As an alternative, premanufactured hood packagings may be used.

(105) A hood packaging (28) may be produced at a packaging station (19) preferably in an automated manner from a tube with doubly wrapped sides, which has a double T-shaped cross section. The doubly wrapped tube is pulled off in a flat form from a stock, especially from a coil, and cut off to obtain a piece of a suitable length. One of the tube ends is closed with a straight closing point. The closing point preferably extends at right angles to the direction in which the tube section is pulled off and closes an open end of the tube, possibly in an airtight manner. Such a closing point may be prepared, for example, by welding. As an alternative, any other desired closing technique may be employed.

(106) The closed tube end may form the bottom side of the hood packaging (28). After closing on one side, the tube may be unfolded at its end that is not closed. The unclosed end may correspondingly form the filling side of a hood packaging (28). Unfolding is preferably carried out such that shortening means (46) pick up the four corner points of the tube and pull them apart in a rectangular shape, e.g., at right angles to the direction of wrapping. The hood packaging (28) now opens and forms an open bag shape.

(107) As an alternative, the unfolding of an open tube end may be brought about by a separate opening means. The tube or hood packaging (28) can be transferred by the opening means with the opened side to shortening means (46) of an applicator (38). A premanufactured tube or hood packaging can also be unfolded manually and possibly transferred to the shortening means (46).

(108) The packaging means can be pulled over in the area of its enveloping sides on the shortening means (46) from the opened side (filling side) of the tube or hood packaging (28). The pulling over is preferably carried out by corresponding conveying means at the shortening means (46). These may be, for example, controllably driven friction rollers (not shown). As an alternative, any other desired conveying means may be used.

(109) The tube or hood packaging (28) is pulled over the applicator, especially the shortening means (46), preferably over a controllable length of the tube area. The pulling over is carried out in case of a hood packaging (28) preferably from the filling side to the extent that the closed end (40), which forms a stretched bottom side between the shortening means (46), is reached. The result of a hood packaging (28) pulled over in this manner is shown in FIG. 27. The described production, unfolding and pulling over of a hood packaging (28) may preferably take place fully automatically.

(110) The applicator (38) may be preferably designed as an expandable stretching frame. Such a design is obtained, for example, by a movable arrangement of the shortening means (46) at the applicator (38). Mobility of the shortening means (46) can, in particular, be provided in such a way that these means are displaceable towards the outside essentially in the direction of the diagonal of a frame-shaped pulled-over packaging means (28). As an alternative or in addition, the shortening means (46) may be movable in the direction of the longitudinal sides of a packaging means (28) pulled over in a frame-like manner. By moving the shortening means (46) apart, prestretching of the pulled-over hood packaging (28) can take place in the area of the enveloping sides.

(111) FIG. 27 shows a pressed bale (25), which is held in a bale receptacle (6). The bale receptacle is shown in an exemplary orientation, in which the support elements (20) point upward and the front side of the pressed bale (25), which front side is freely accessible from the outside and is located in the direction of the ends of the support elements (20), thus points upward as well. An applicator (38), over which a hood packaging (28) is pulled, is arranged above the pressed bale. This orientation in space of the bale receptacle (6) and applicator (38) is selected here merely for reasons of greater clarity. As an alternative, any other desired orientation may be selected. The relative orientation of the bale receptacle (6) and applicator (38) should preferably be selected such that the applicator (38) can be moved essentially in parallel to the extension of the support elements (20) over the bale receptacle (6) and the pressed bale (25) being held therein. In other words, the relative orientation of the applicator (38) and bale receptacle (6) is preferably selected such that a pulling-over or overturning motion for applying a tube or hood packaging (28) being held at the applicator (38) takes place essentially in parallel to the course of the support elements (20). The absolute orientation can be correspondingly selected freely.

(112) A hood packaging (28) can be applied on a pressed bale (25), for example, in the manner shown in FIGS. 27 through 35. According to FIGS. 27 through 29, an applicator (38) can be pulled by a relative motion over the bale receptacle (6) and the pressed bale (25) being held therein. In the course of the motion, the hood packaging (28) makes contact first with the closed bottom side (40) with the outwardly freely accessible front side of the pressed bale (25). Packaging means (39) being stored is released from the shortening means (46) during the further motion of the applicator (38) and pulled over the circumferential sides of the pressed bale and the support elements (20), while it forms the enveloping sides of the hood packaging (28).

(113) The pulling-over motion of the applicator (38) over the pressed bale (25) can preferably take place at first to the extent that the enveloping sides of the hood packaging (28) cover the circumferential sides of the pressed bale essentially completely, but a remainder of stored packaging material (39) still remains on the applicator (38). This position is shown in FIG. 29.

(114) The bale receptacle (6) can preferably be separated from the pressed bale (25) in a relative motion, while the hood packaging (28) covers the front side and the circumferential sides of the pressed bale (25). The relative motion can be brought about in different ways. On the one hand, it is possible to remove the pressed bale (25), e.g., by means of a push-out device (8) from the bale receptacle (6). The pulled-over hood packaging (28) may be entrained now due to it being in contact with the front side of the pressed bale (25). As an alternative, or in addition, the pressed bale (25) can be taken up for removal of the bale receptacle (6) between two pressure or holding rams (41). The pressure or holding rams (41) may be designed in the manner of the aforementioned pressure rams (11, 12, 13, 14) of a press and have recesses or recessed channels in the active surfaces, which correspond to the support elements (20). The pressure or holding rams (41) are preferably arranged at the packaging station (19).

(115) Corresponding to the above explanations given for FIGS. 12 through 15 and 24 through 26, the pressed bale (25) can be picked up between pressure or holding rams (41). The course of the packaging means (28) of the hood packaging between the pressed bale (25), support elements (20) and pressure or holding rams (41) can be selected suitably, especially corresponding to FIGS. 24 through 26, depending on the amount of feed of the pressure or holding rams (41), with the pressure or holding rams (41) surrounding the support elements (20). The amount of feed of the pressure or holding rams (41) at the pressed bale (25) can be especially such that the pressed bale is partially or fully released between the support elements (20).

(116) As an alternative, rigidly arranged pressure or holding rams (41) and a bale receptacle (6) with displaceable sets of support elements (20) may be provided. The bale receptacle (6) can be moved in such a case with the hood packaging (28) applied into the area between the pressure or holding rams (41) and then opened. Due to the opening, the support elements (20) can dip into the recesses in the active surfaces of the pressure or holding rams (41), while the pressed bale (25) and optionally the hood packaging (28) expand. The bale receptacle (6) can be optionally opened to the extent that the pressed bale (25) is held by its expanding motion fully between the pressure or holding rams (41).

(117) FIGS. 30 and 31 show a preferred embodiment of a packaging station (19) with pressure or holding rams (41) that can be fed, can be brought into contact with a pressed bale (25) on the side and can fully or partially pick up said pressed bale (25). With the pressure or holding rams (41) brought into contact, the bale receptacle (6) can be pulled out in the direction of the open side (bottom side) of the hood packaging (28), here in the downward direction.

(118) An excess amount of packaging means (28) can remain held on the applicator (38) during the separation of the bale receptacle (6) from the pressed bale (25) and the hood packaging (28) applied thereon. This excess amount of packaging means (28) may be a tube-shaped area of the packaging means (28), which is preferably selected to be so large that it can be placed, covering, over the still free side of the pressed bale (25). FIG. 32 shows as an example a pressed bale (25) after removal of the bale receptacle (6). The pressed bale (25) is picked up between two pressure or holding rams (41). An excess amount of packaging material (28) forms a half-open tube end (42) on the rear side (here underside) of the pressed bale (25).

(119) A packaging station (19) may preferably have means for placing a half-open tube end (42) of a tube or hood packaging (28) applied on the pressed bale over the pressed bale (25). The laying means may have any desired design, for example, they may be designed as a folding device with movable material grippers and folding knives. Different forms of suitable laying means are known in practice. FIGS. 33 through 35 show, for example, a possibility of laying a half-open tube end (42) on the pressed bale (25). Two mutually opposite sides of the half-open tube end (42) can be folded towards the pressed bale (25) (arrows in FIG. 33) in a first step. The other two sides of the half-open tube end (42) can be laid on the pressed bale (25) in a further step, and these sides cover the first two sides. As an alternative, any other desired method may be used to lay the half-open tube end (41).

(120) A tube or hood packaging (28) may preferably sealingly surround a pressed bale (25) on all sides. It may be applied especially with vacuum and form a fixing for the pressed bale. A packaging sealing on all sides can be applied, for example, by means of a tube or hood packaging (28). The tube or hood packaging (28) can be applied on a pressed bale (25) according to the above explanations and the views shown in FIGS. 27 through 32. As an alternative, it may be applied in a different way.

(121) An open tube end (42) of a hood packaging (28) can be preferably placed on the pressed bale (25) and closed in such way that a vacuum is generated in the hood packaging. This is shown as an example in FIGS. 33 through 35. The vacuum may be generated in any desired manner. A suction means (43), which generates a reduced pressure or a vacuum within the packaging (28) by means of a suction pipe (44) during the laying of the half-open tube end (42) on the pressed bale (25), may be preferably provided. The pipe may also be inserted, for example, into the overlapping sides of the laid packaging (28). The sides applied can be closed by a suitable device in the laid-down position, for example, by a welding means (45).

(122) As an alternative, a half-open tube end (42) can be first closed and then placed on the pressed bale, while vacuum is generated in the packaging (28). A tube or hood packaging (28) may have for this purpose, for example, a valve, via which a reduced pressure or vacuum is generated in the packaging (28) by means of a suction means (43). The half-open tube end (42) may be closed in any desired manner. It may be closed especially by a welding means (45). The at first half-open and then closed tube end (42) can also be placed simply by generating the reduced pressure in the packaging (28), without controlled placement being provided.

(123) In a variant of the application of a hood packaging (28) shown in FIGS. 27 through 35, a tube packaging open on both sides can be pulled alternatively over a pressed bale (25) by means of an applicator (38). After removing the bale receptacle (6), the two half-open tube ends (42) can then be closed and possibly laid on the pressed bale (25), while a reduced pressure is optionally generated in the packaging (28).

(124) A hood packaging (28) may be preferably applied on a pressed bale (25) by a pulling-over or overturning motion. The shortening means (46) at the applicator (38), especially the shortening fingers (46), can be arranged such that they point away from the bale receptacle (6) and the pressed bale (25). This is shown in FIGS. 27 through 31. The applicator (38) is preferably designed in this configuration to perform a pulling-over motion. As an alternative, the shortening means (46) may be arranged at the applicator (38), especially the shortening fingers, such that they point to the bale receptacle (6) and to the pressed bale (25), as is shown, for example, in FIGS. 36 and 37.

(125) The packaging means (39) being stored on the shortening means (46) is running off essentially in a straight line with a pull-off angle of 0 to 90 during a pulling-over motion. The pull-off angle is the angle that is formed between an imaginary extension of the shortening means (46) and the actual course of the stretched film material during the transfer of the latter to the circumferential sides of the pressed bale (25). The packaging means (39) being stored runs, by contrast, around the ends of the shortening means (46) in an arc-shaped pattern during an overturning motion, and a pull-off angle between 90 and 180 is formed. The material of the hood packaging (28) is turned from the inside to the outside during an overturning motion. The side of the hood packaging (28) that has pointed outwardly on the applicator (38) forms the inside in the position in which it is applied on the pressed bale and vice versa. FIG. 38 shows the running of the packaging means (28) around a shortening means (46) during an overturning motion in an enlarged view.

(126) The use of a pulling-over or overturning motion may have various advantages. A hood packaging (28) can be applied during a pulling-over motion on the side of the applicator that faces away from the pressed bale. The charging of the applicator (38) with a new tube or hood packaging can thus take place separately in space from the application to a pressed bale. An applicator (38) can already be charged with a new tube or hood packaging (28) in this manner while a pressed bale (25) is still located in the packaging station (19), so that the packaging station (19) can have an especially short work cycle.

(127) A specially controlled application of the tube or hood packaging (28) to the pressed bale can take place during an overturning motion. In particular, the packaging means (28) can be released in the area of the shortening means (46) with a controlled tension. The tube or hood packaging (28) can thus also be applied in the direction of the application motion with an elastic prestretching.

(128) A tube or hood packaging (28) may also be able to be applied to a pressed bale (25) at a packaging device (18). For example, a modified packaging means (18) may be provided with an applicator (38) for applying a tube or hood packaging at a press (3, 4) in a variant of the exemplary embodiment shown in FIGS. 11 through 18. The application of a tube or hood packaging (28) may take place analogously to the above explanations via a packaging station and analogously to FIGS. 27 through 37. The applicator (38) may be displaceable, for example, in the horizontal direction and able to be displaced between the pressure rams (13, 14) of a finishing press (4).

(129) For example, a packaging technology in which a bale receptacle (6) is inserted at first into a press (4) with a pressed bale (25) being held therein analogously to FIGS. 11 and 12 may be carried out on a packaging device (18) thus modified. An applicator can then apply a tube or hood packaging (28) over the pressed bale (25) and the bale receptacle (6) from the push-out side of the press (4). The pressure rams (13, 14) can then optionally be closed somewhat and brought into contact with the pressed bale (25), and the pressure rams (13, 14) surround the support elements (20). The pressed bale (25) can be picked up and held partially or completely in the press (4) in this manner.

(130) The bale receptacle (6) may be separated from the pressed bale (25) optionally while actuating a push-out device (8) at the same time and moved out of the tube or hood packaging applied.

(131) One half-open tube end (42) or both half-open tube ends (42) of the tube or hood packaging (28) may be subsequently closed and optionally placed on the pressed bale (25).

(132) If the pressed bale (25) shall be subjected to yet another pressing operation, the pressure rams (13, 14) can optionally compress the pressed bale (25) enveloped in the tube or hood packaging further after removal of the bale receptacle (6). This can take place while the tube ends are still open or are already closed. In particular, final pressing can take place simultaneously with the closure and optionally the placement of the tube ends.

(133) The tube or hood packaging (28) closed on both sides can be preferably applied with reduced pressure. The reduced pressure may be generated in any desired manner. In particular, a suction means (35) may be provided at the modified packaging device (18). The suction means can enter an open tube end of the tube or hood packaging (28), for example, via a suction pipe corresponding to the above explanations and generate a reduced pressure in the packaging (28) before or during closure. As an alternative, a valve may be provided in the tube or hood packaging (28).

(134) The pressed bale (25) may be preferably fixed by the reduced pressure in the tube or hood packaging (28). As an alternative or in addition, a fixing means, especially a one-part or multipart strapping (31), may be applied on the pressed bale (25). The fixing means may be applied on the tube or hood packaging (28) especially on the outside, so that contamination of or damage to the pressed bale (25) due to the fixing means is prevented from occurring. A fixing means may be applied especially by means of a strapping device according to one of the aforementioned exemplary embodiments.

(135) The present invention is not limited to the exemplary embodiments shown and described. The features shown and described may be combined, interchanged or omitted as desired. In particular, a bale press plant (1) may be provided with a transporting device (5) of the type described, but without a packaging system (18) or packaging station (19). A packaging system (18) may likewise be arranged independently from an additional press (4), especially a finishing press. All features of a packaging stations (19) may be extrapolated to a packaging device (18) in a corresponding manner and vice versa. The transporting device (5) may also be designed independently from a bale press (2) and pick up, for example, strapped pressed bales, in which case the strapping is opened within a bale receptacle (60, so that the compressed pressed bale is relaxed in the direction of the support elements (20) in a controlled manner. The pressed bale (256) can thus be secured against uncontrolled expansion.

(136) The feed of packaging material (28), especially film material or tube material, to a packaging system (18) or to a packaging station (19) may be designed as desired. For example, a stock may hold one or more packaging materials, tube or film sections already cut into a length. As an alternative, a film curtain may be applied manually or in an only partly automated manner. The means (30) for stretching a film web (28) may be, for example, statically or movably arranged film holders in this case.

(137) Strapping (31) may also be applied manually or in a partly automated manner. A strapping apparatus (37) may be operated, for example, manually and cooperate with an adjustable deflecting means (36). The plurality of strapping bands of a strapping (31) may be placed as a group and, e.g., simultaneously or one by one, one after another, and optionally also be gathered.

(138) While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
