DETAILED DESCRIPTION

[0057] Identical reference numbers are used in the drawings for elements which are the same or have the same effect. Moreover, for the sake of easier overview, only reference numbers are represented in the individual figures which are necessary for the description of the respective figure. At least one possible exemplary embodiment is also represented in the figures only as a schematic view in order to explain the method of working. In general, the representations in the figures may serve only to explain one or more underlying principles of at least one possible exemplary embodiment. For reasons of easier overview, the representation of some of the component parts of the device has been avoided.

[0058] FIG. 1A shows a schematic top view of a container handling or beverage bottling machine 100 for handling containers 102, such as bottles, cans, kegs, or similar containers, in accordance with at least one possible exemplary embodiment. The container handling machine 100 comprises a rotor or carousel 101 designed to rotate about a vertical axis of rotation. A plurality of container handling arrangements 103 are disposed about the periphery of the rotor 101. The container handling arrangements 103 can be designed to perform different functions depending on the container handling machine 100, such as container filling, closing, labeling, and other such container handling functions. A first rotary container transport device 104, such as a star wheel or similar device, moves containers 102 into the container handling arrangements 103. A second rotary container output device 105, such as a star wheel or similar device, moves containers 102 out of the container handling arrangements 103. A control arrangement 106, such as a computer control arrangement, is operatively connected to the container handling machine 100 to control and/or monitor the operation of the container handling machine 100 and the components thereof.

[0059] FIG. 1 shows a labeling device or unit or arrangement 1 of a labeling machine for the labeling of bottles or similar containers 2 with what are referred to as roll-fed labels 3, which are drawn off from a supply roll 4 of an endless strip-form labeling material 3.1. The labels 3 are cut off in the respective length of the labeling material 3.1 necessary for a label 3 by use of a cutting unit 5 of the labeling device 1. The labels 3 obtained in this way are transferred over a labeling and transfer drum 6 to the containers 2, which are being moved past on a rotor 7 of the labeling machine at the labeling unit 1, circulating about a vertical machine axis, and then applied to the containers 2. The directions of rotation of the rotor 7 and of the transfer drum 6 are indicated by the arrows A and B respectively.

[0060] The label material 3 is drawn from a supply roll 4 by use of conveying rollers 8 and 9, in synchrony with the movement of rotation of the rotor 7, and fed to the cutting unit 5. The cutting unit 5 comprises a cutting drum 10, which during the labeling is driven such as to circulate about a drum axis TA in the manner represented by arrow C, which is in the counter-direction to the direction of rotation B of the transfer drum 6. This cutting drum 10 is the same as or similar to other cutting drums that are generally well known in the beverage bottling industry, so a more detailed description has therefore been avoided.

[0061] As seen in FIG. 2, the cutting drum 10, about its periphery, has a drum peripheral surface 10.1 that is generally circular or generally in the form of a circular cylinder. At this periphery or peripheral surface 10.1, the cutting drum 10 comprises two first blade elements 11 disposed opposite to one another with respect to the drum axis TA, although any number of first blade elements 11 could be included in at least one possible exemplary embodiment. FIG. 3 shows an enlarged or close up view of the area within the circle X in FIG. 2. As shown in a schematic or operational or representative view in FIG. 4, each of the first blade elements 11 comprises a first cutting edge 11.1 and is oriented or disposed or positioned such that the first cutting edge 11.1 is parallel or essentially parallel or substantially parallel to the drum axis TA of the cutting drum 1. Each of the first blade elements 11 is designed and positioned to interact with at least one blade element 12, which comprises a second cutting edge 12.1. The blade elements 11, 12 define a cutting gap ST and interact in such a way that, at a rotation of the cutting drum 10, due to the interaction of the first cutting edge 11.1 of the first blade element 11 with the second cutting edge 12.1 of the second blade element 12, the length of label material 3.1 which forms the label 3 is cut off to form an individual label 3. The label 3 is then temporarily held on the peripheral surface 10.1 of the cutting drum 10, for example by vacuum, and transferred to the transfer drum 6.

[0062] In other words, the cutting unit 5 therefore cuts a label 3, in that the rotating first blade element 11, provided at a drum periphery 10.1 of the cutting drum 10, moves past at the second blade element 12, provided at a switching and adjusting device 13 and functioning as a counter-blade, and the cut therefore takes place.

[0063] In greater detail, with respect to the exemplary embodiment represented in FIG. 4, the first cutting edge 11.1 is formed at a first flat side surface FL1 of the first blade element 11, preceding in the direction of rotation C of the cutting drum 10, or of the part region of this first blade element 11 projecting over the drum periphery surface 10.1. The first cutting edge 11.1 is oriented and positioned such that, upon the cutting drum 10 being driven such as to circulate, the first cutting edge 11.1 essentially or substantially moves on a path concentrically surrounding the vertical drum axis TA in the form of a circle or circular cylinder. In accordance with at least one possible exemplary embodiment, the first cutting edge 11.1 is also oriented parallel to the drum axis TA.

[0064] Allocated to the first rotating blade element 11 or to its first cutting edge 11.1 is a second blade element 12, taking effect as a counter-blade, with a second cutting edge 12.1. The second blade element 12 does not circulate with the cutting drum 10 at the cutting unit 5, wherein it is disposed in a fixed or stationary position relative to the cutting drum 10. and specifically at the switching and adjusting device 13, in such a way that the second blade element 12, or, respectively, its second cutting edge 12.1, can be adjusted radially or approximately radially in relation to the circulating drum 10 (arrow E). For an adjustment setting, the second blade element 12 or its second cutting edge 12.1 respectively, can be adjusted, for example, in such a way that the second blade element 12, or its cutting edge already present immediately after installation into the cutting unit 5, is oriented at least approximately parallel to the first cutting edge 11.1 when this is located directly at the second cutting edge 12.1.

[0065] In accordance with at least one possible exemplary embodiment, the first and second cutting edges 11.1, 12.1, are provided as restricted in relation to one another in their respective longitudinal extension along the drum axis TA, i.e., are not parallel. In accordance with at least one possible exemplary embodiment, the first and second cutting edges 11.1, 12.1, are provided as mutually restricted by 0.2 mm to 0.7 mm, such as by approximately 0.5 mm, over their respective longitudinal extensions, in such a way that a contact in point form can be produced between the two cutting edges 11.1, 12.1. In other words, in accordance with at least one possible exemplary embodiment, when the first and second cutting edges 11.1, 12.1 meet or are disposed adjacent one another in a cutting process, the edges are not oriented parallel to one another, that is, one edge is offset or at an angle to the other, such that the edges are oriented transverse to one another and would appear to cross or overlap one another. Accordingly, instead of the edges being aligned across their length or substantially their entire length, only a portion of the edges intersect or overlap with one another. This positioning is not unlike the positioning of the blades of a pair of scissors, wherein the individual blades are offset such that they intersect or cross or overlap over a limited or restricted area or point at any given time as the blades are moved with respect to one another in a cutting process. This offset design of scissors allows the blades to gradually cut across an item being cut, rather than the blades meeting across their entire lengths in a chopping motion, such as when a flat knife or cleaver is brought down upon a parallel cutting service or chopping block in a perpendicular motion. Therefore, in accordance with at least one possible exemplary embodiment, the first and second cutting edges 11.1, 12.1, as the first blade element 11 is moved past the second blade element 12, the first and second cutting edges 11.1, 12.1 meet or intersect or cross or overlap or lie transverse to one another over a point or a limited or restricted area in the range of about or exactly 0.2 mm to 0.7 mm, including values in tenths and hundredths of a millimeter. In accordance with at least one possible exemplary embodiment, this point or area could be about or exactly 0.5 mm, which includes values in tenths or hundredths of a millimeter down to 0.4 mm or up to 0.6 mm. This intersection point or area is essentially where the first and second cutting edges 11.1, 12.1 interact to cut the label material. An example of this offset can be seen in the close up view in FIG. 3, wherein the sides of the first blade element 11 are parallel or essentially parallel to the drum axis TA, and thus not visible from the top view in FIG. 3 along the drum axis TA. In contrast, the sides of the second blade element 12 are not parallel or are at an angle to the drum axis TA, and thus portions of two of the sides are visible from the top view in FIG. 3 along the drum axis TA. However, this positioning is in accordance with at least one possible exemplary embodiment and other positions or orientation of the blade elements 11, 12 are possible to achieve different cutting relationships and processes. For example, the cutting edges 11.1, 12.1 can be oriented parallel, or essentially parallel, or substantially parallel to one another and/or the drum axis TA.

[0066] In this situation, a cutting gap ST is formed between the first cutting edge 11.1 and the second cutting edge 12.1, and specifically in such a way that at each cutting process, i.e., with the cutting drum 10 rotating, whenever the first blade element 11, rotating with the cutting drum 10 in a torsionally-resistant or rotationally-fixed manner, moves past the second fixed-positioned blade element 12, the first and second cutting edges 11.1 and 12.1 just come in contact, or just do not come in contact, and preferably over the entire length of the cutting gap ST extending in the direction of the drum axis TA. In other words, the first and second blade elements 11, 12 are positioned such that the first and second cutting edges 11.1, 12.1, during the cutting process, barely or very slightly or minimally contact one another, or they come very close to contacting one another, such that the label material is cut but the first and second cutting edges 11.1, 12.1 do not contact each other at all.

[0067] The length of the cutting gap ST in this situation is at least equal to, or possibly greater than, the width of the band-form or web-form label material 3.1. In this situation, the band-form or web-form label material 3.1 moves through the cutting gap ST in the direction of the transfer drum 6, and is, for example, at least in the region of the cutting gap ST, oriented in or essentially in or substantially in a plane F parallel to the drum axis TA.

[0068] In order to adjust and/or align the cutting gap ST, provision is made in this situation for the second measuring element 12 to comprise at least in the region of its second cutting edge 12.1 a second hardness, which is configured as greater than a first hardness at least in the region of the first cutting edge 11.1 of the first blade element 11. Accordingly, the fixed position second blade element 12 is configured, at least in the region of its second cutting edge 12.1, as harder than the rotating first blade element 11 in the region of its first cutting edge 11.1. Accordingly, the first cutting edge 11.1 of the first blade element 11 can be produced by material removal at the second cutting edge 12.1 of the second blade element 12 with the greater second hardness. In other words, in accordance with at least one possible exemplary embodiment, the second cutting edge 12.1, due to its greater hardness, can be used to form and/or sharpen the first cutting edge 11.1, due to its lesser hardness.

[0069] According to at least one possible exemplary embodiment, the first blade element 11 is formed, at least in the region of its first cutting edge 11.1, from a steel, such as a steel of the group of the cold-work steels, and the second blade element 12 is formed, at least in the region of its second cutting edge 12.1, from a carbide metal.

[0070] In order to achieve the required cutting gap ST by material removal, therefore, the second blade element 12 is produced, at least in its cutting region forming the second cutting edge 12.1, with a hardness which is greater in comparison with the first hardness, in that it is manufactured from carbide metal, for example from hardened steel, tool steel, or ceramics, while the first blade element 11 is manufactured from a material which is softer in comparison with the cutting region of the second blade element 12, namely a steel from the group of the cold-work steels.

[0071] In this situation, the first blade element 11 is formed or manufactured from a full material of a steel from the group of the cold-work steels, and/or the second blade element 12 from a full material of a carbide metal. In other words, in accordance with at least one possible exemplary embodiment, the first blade element 11 can be made entirely from a steel from the group of the cold-work steels, and the second blade element 12 can be made entirely from a carbide metal.

[0072] The steel from the group of the cold-work steels can be an unalloyed or alloyed cold-work steel.

[0073] The steel from the group of the cold-work steels exhibits a first hardness according to Rockwell of 55 HRC to 59 HRC. The inventors discovered, after substantial testing, that with a first hardness of over 59 HRC it is no longer possible for adequate material to be removed for the subsequent sharpening of the cutting edges. The inventors also discovered that, with a first hardness of less than 55 HRC, both the blade elements 11, 12 can indeed be well sharpened subsequently, but the wear increases disproportionately due to the abrasive surface of the label material.

[0074] In accordance with at least one possible exemplary embodiment, the steel from the group of the cold-work steels is configured as a cold-work steel with the material number EN 1.2550 (DIN 60WCrV7, AISI S1), or as a cold-work steel with the material EN 1.2379 (DIN X153CrMoV12, AISI D2), or as a cold-work steel with the material number EN 1.4034 (DIN X46Cr13, AISI 420). The steel from the group of the cold-work steels can also be configured as the cold-work steel Vanadis® 10 or Viking, with a chemical composition of C 0.5%, Si 1%, Mn 0.5%, Cr 8%, Mo 1.5%, and V 0.5%.

[0075] As a carbide metal used for the second blade element 12, in the present case a metallic material is understood to be a metal matrix composite material in which the hard materials, which are present as small particles, are held together by a matrix of metal. The carbide metal accordingly exhibits a high degree of toughness.

[0076] The carbide metal of the second blade element 12 can be configured as a tungsten carbide-cobalt carbide metal type (WC—Co) and/or as a carbide metal type for steel working (WC—(Ti,Ta,Nb)C—Co) and/or as a Cermet carbide metal type.

[0077] By contrast with conventional cutting materials, such as high-speed steels, carbide metals exhibit a lesser fracture toughness and thermal shock resistance. Conversely, however, they have significant advantages such as greater hardness and temperature resistance. In particular, the high degree of hardness leads to a high abrasive wear resistance. This alone allows for higher cutting speeds. These can also be achieved, since carbide metals can exhibit a temperature resistance of up to 1100 degrees Celsius.

[0078] Advantageously, the carbide metal exhibits in this situation a second hardness according to Vickers of 1150 (HV30) and/or a fracture toughness according to Palmqvist of 15.5 MN/mm. Accordingly, the carbide metal exhibits an adequate degree of toughness such that, at the impacting stress incurred when the two blade elements 11, 12, come in contact, no or essentially no or very little or a minimal amount of material will break off from the cutting edges.

[0079] When the cutting device is first taken into operation, for example also after a replacement of function elements of the cutting device 1, such as of one of the blade elements 11 and 12, there is first a rough adjustment of these blade elements, or possibly only one of the blade elements, such as only the second blade element 12 as in the embodiment shown in FIG. 5, in such a way that the second blade element 12 is oriented at least approximately parallel to the first blade element 11 or to its cutting edge 11.1 respectively. This adjustment can be carried out by use of the switching and adjusting device 13. Next, with the cutting drum 10 revolving, an adjustment is carried out of the second blade element 12, such that, with the second cutting edge 12.1, by the removal of material at the first blade element 11, the first cutting edge 11.1 is formed. The adjustment of the second blade element 12 to the circulating cutting drum 10 by use of the switching and adjusting device 13 is then ended when the first cutting edge 11.1, produced by the removal of material, extends over the entire length of the cutting gap ST, and the cutting gap ST is configured over its entire length in such a way that the second cutting edge 12.1, and the first cutting edge 11.1, formed by the removal of material, at each movement of the blade element 11 past the blade element 12, just come in contact over the entire length of the cutting gap ST, or, likewise, no longer just come in contact. On the basis of cutting samples of the label material 3.1, the appropriate formation of the cutting edge 11.1 can be monitored and determined, and the adjustment of the second blade element 12 is then ended when the formation of the first cutting 11.1 is concluded by the material removal produced by the second cutting edge 12, or when the cutting process for the detachment of a label is taking place over the entire label width uniformly and without any defects, or at least with a minimal number of defects within manufacturing tolerances.

[0080] During the operation of the cutting device, a slight manual readjustment or setting of the second blade element 12 can be carried out, for example, by use of the switching and adjusting device 13, in order to re-sharpen the first cutting edge 11.1. In other words, the positioning of the second blade element 12 can be adjusted either while the cutting drum 10 is rotating or while the cutting drum 10 is stationary.

[0081] In this situation, provision can also be made that, time-controlled and/or as a dependency of the number of cuts carried out, i.e., in each case after a predetermined number of cutting procedures, an automatic slight readjustment or setting of the second blade element 12 can be carried out in the direction of the first cutting edge 11 by use of the switching and adjusting device 13, in order to re-sharpen its cutting edge, i.e., in order to avoid the second cutting edge 12 being worn away by the abrasion. In other words, the position of the second blade element 12 can be adjusted automatically on a schedule, or it can be manually or individually adjusted as needed.

[0082] In order to form the first cutting edge 11.1, the second blade element 12 comprises a flat surface FL2 in a plane F, in which, as the first blade element 11 moves past the second blade element 12, the first cutting edge 11.1 and/or its first flat side surface FL1 of the first blade element 11 are also arranged, and which extends transversely to the direction of movement of the first cutting edge 11.1 when moving past at the second blade element 12, i.e., the plane F extends approximately radially to the machine axis TA, or essentially parallel to a radius of the machine axis TA.

[0083] There is also the possibility for the first and/or second blade element 11, 12 to be treated and/or coated at least in part regions on the surfaces, in order to produce their corresponding first and/or second hardnesses.

[0084] FIGS. 5-8 show at least one possible exemplary embodiment of a labeling machine and components thereof. In order to adjust the cutting gap ST, provision can be made in this situation for the second blade element 12 to be pivoted, by use of a first joint section GA1 formed at the switching and adjusting device 13, between a cutting position SP and a waiting position WP, in a controlled manner. When the second blade element 12 is in the cutting position SP, it is in working engagement with the rotating first blade element 11, i.e., they are interacting and thus cutting labels 3, while when the second blade element 12 is in the waiting position WP, it is out of working engagement with the blade element 11, i.e., they are not interacting and thus not cutting any labels 3.

[0085] Moreover, by use of a second joint section GA2, formed at the switching and adjusting device 13, the cutting gap ST, formed between the first blade element 11 and the second blade element 12, can be adjusted independently of the controlled pivot movement of the first joint section GA1.

[0086] In this situation, the switching and adjusting device 13 can be configured in such a way as to pivot the first joint section GA1 between the cutting position SP and the waiting position WP in a controlled manner in such a way that, in the event of isolated gaps occurring in the bottle stream of the labeling device 1, no label will be cut for at least this one empty unoccupied container handling position at the rotor 7, with the second blade element 12 therefore being taken out of engagement for a short period with the first blade element 11 provided at the cutting drum.

[0087] In greater detail, the cutting unit 5 comprises a housing 21, in which all or essentially all of the components and modules are arranged or accommodated. In accordance with at least one possible exemplary embodiment, the switching and adjusting device 13 is arranged in the housing 21 by use of a plate-shaped holder 15, which may be screwed to the housing 21 in a detachable manner. In turn, all the components and modules of the switching and adjusting device 13 explained in greater detail hereinafter are held on or mounted on or supported by the plate-shaped holder 15.

[0088] In this situation, a switching device 19 is provided on the plate-shaped holder 15 for the controlled pivotable movement of the first joint section GA1 between the cutting position SP and the waiting position WP of the second blade element 12. In accordance with at least one possible exemplary embodiment, the switching device 19 is configured as a pneumatic cylinder device, which can produce an adjustment movement on both sides or in two directions, identified by a double arrow D.

[0089] Provided on the side opposite the switching device 19, on the holder 15, is a solid body joint 14, with an essentially U-shaped profile, formed on which are the first and second joint sections GA1, GA2. In greater detail, the U-profile shaped solid body joint 14 comprises in this situation a first side limb section 14.1, with which the solid body joint 14 is arranged at the holder 15. In the embodiment shown, the solid body joint 14 is secured to the holder 15 in a detachable manner, for example by being screwed to it. Further provided is a second side limb section 14.2, oriented essentially parallel to the first side limb section 14.1, wherein both the side limb sections 14.1, 14.2 are connected to one another by a third base limb section 14.3, which runs or is oriented perpendicular or essentially or substantially perpendicular to the two side limb sections 14.1, 14.2.

[0090] In greater detail, in this situation the first joint section GA1 is formed on the solid body joint 14 in the transition region between the first side limb section 14.1 and the base limb section 14.3, and the second side limb section GA2 is formed in the transition region between the second side limb section 14.2 and the base limb section 14.3. In accordance with at least one possible exemplary embodiment, the solid body joint 14 is configured, at least in its respective joint sections GA1, GA2, as being elastically deformable. In other words, the joint sections GA1 and GA2 are flexible or elastically deformable to permit the pivoting or adjustment movement of the second blade element 12 operatively connected thereto.

[0091] In accordance with at least one possible exemplary embodiment, the solid body joint 14 is formed with the first and second side limb sections 14.1, 14.2, and the base limb section 14.3 connecting the side limb sections 14.1, 14.2, as one part or as an integral unit, and is manufactured from a metallic material.

[0092] On the base limb section 14.3, the switching and adjusting device 13 comprises, in order to initiate the pivoting movement between the cutting position SP and the waiting position WP onto the second blade element 12, a switching lever element 16, extending essentially in an L-shape, as viewed from above, such as shown in FIGS. 5 and 8. The switching lever element 16 is arranged with its first side 16.1 formed on a short limb and connected or secured to the base limb section 14.3 in a detachable manner. The switching lever element 16 comprises a second side 16.2 that is formed at or on a longer limb. As can be best seen in FIGS. 6 and 8, a cut-out opening or recess or receiver 23 is formed at or in the second side 16.2, which cut-out opening 23 is configured to engage or interact with the switching device 19 in such a way that the switching lever element 16, at the initiation of an adjustment movement by the switching device 19, can be pivoted about the first joint section GA1. The pivoting movement on both sides is indicated by a double arrow E.

[0093] In addition, the switching element 16 comprises in the region of its free end section of the second side 16.2 a mechanical stop 20, by use of which the deflection of the switching lever element 16, i.e., the lift of the pivot movement between the waiting position WP and the cutting position SP, can be adjusted or is adjustable. By way of example, the stop 20 can be formed by a threaded spindle 20.1 screwed into the holder 15, at which in each case a stop element 20.2, 20.3 is provided, for example in the form of a nut, on opposing sides of the switching lever element 16.

[0094] In this situation, the stop element 20.2, provided at the threaded spindle 20.1 on the side facing away from the holder 15, forms a mechanical end stop for the maximum possible deflection of the switching lever element 16, in which the second blade element 12 is in its cutting position SP, i.e., is in working engagement with the first blade element 11 for the cutting of labels. The stop element 20.3, provided on the side of the threaded spindle 20.1 facing towards the holder 15, forms a mechanical end stop for the waiting position WP, in which the second blade element 12 is out of working engagement with the first blade element 11. By rotating the respective stop elements 20.2, 20.3 along the longitudinal axis of the threaded spindle 20.1, the corresponding end stop can be steplessly adjusted.

[0095] In addition to this, the switching and adjusting device 13 comprises, on its second side limb section 14.2, a blade holder 17, at which the second blade element 12 is held in such a way that it can be replaced. In at least one possible exemplary embodiment, the second blade element 12 is oriented to run parallel to the drum axis TA. In at least one possible exemplary embodiment, however, the blade holder 17, together with the second blade element 12 held by it, during a controlled pivot movement about the first joint axis GA1, pivots between the cutting position SP and the waiting position WP over the solid body joint 14, in a manner directly proportional to the deflection of the switching lever element 16.

[0096] In accordance with at least one possible exemplary embodiment, the blade holder 17 is arranged at the second side limb section 14.2 securely but detachably, such as being screwed to the second limb section 14.2. In accordance with at least one possible exemplary embodiment, the blade holder is disposed on or at the outer side of the second side limb section 14.2, opposite the switching element 16.

[0097] For this purpose, the relative positioning of the blade holder 17 provided at the second side limb section 14.2 in relation to the switching lever element 16 can be fixed securely by use of a locking plate 22. For example, for this purpose the locking plate 22 can be screwed both to the switching lever element 16 as well as to the blade holder 17.

[0098] Furthermore, by use of the second joint section GA2 formed at the switching and adjusting device 13, the cutting gap ST formed between the first blade element 11 and the second blade element 12 can be adjusted independently of the controlled pivot movement of the first joint section GA1.

[0099] In greater detail, for this purpose the blade holder 17, including the second blade element 12 held in it, is configured so as to pivot, in order thereby to adjust the blade gap by use of an adjustment device 18 provided at the blade holder 17, about the second joint section GA2 and relative to the switching lever element 16. The pivoting of the blade holder 17 by use of the adjustment device 18 about the second joint range GA2 formed between the second side limb section 14.2 and the base limb section 14.3 therefore takes place independently of the controlled pivot movement of the first joint section GA1.

[0100] For this purpose, the adjustment device 18 can accommodate forces in both directions of the pivot movement formed about the second joint section GA2. In greater detail, the adjustment device 18 can also comprise a threaded spindle 18.1 with a differential thread. In this situation, the threaded spindle 18.1 comprises two thread regions along its shaft, namely a first threaded region W1 and a second threaded region W2, which both exhibit the same thread direction but different thread pitches to one another. In this situation, the first thread region W1 of the threaded spindle 18.1 is accommodated in a counter-thread 17.1 of the blade holder 17, and the second thread region W2 is accommodated in a counter-thread 16.3 of the switching lever element 16.

[0101] For example, the first thread region W1 can exhibit a larger thread pitch than the second thread region W2 of the threaded spindle 18.1. When the threaded spindle 18.1 is tightened, the thread region W1 of the threaded spindle 18.1, with the larger thread pitch, slides in the counter-thread 17.1 of the blade holder 17. At the same time, however, the thread region W2, with the smaller pitch, moves in the counter-thread 16.3 of the switching lever element 16. Since a revolution of the threaded spindle 18.1 results in a shorter distance being covered in the threaded region with the smaller pitch W2, the two threaded regions W1, W2 of the threaded spindle 18.1 are tensioned against one another, i.e. in particular onto one another.

[0102] The adjustment of the blade gap by use of the adjustment device 18 takes place, for example, with the locking plate 22 unscrewed or loosened or unsecured, which, after the adjustment, is then screwed, via the screws 25, or fixed or secured in place onto the switching lever element 16 again, in order to fix the position of the blade holder 17.

[0103] The invention has been described heretofore on the basis of exemplary embodiments. It is understood that numerous modifications and derivations are possible without thereby departing from the underlying inventive concept of the invention.
