The side cover removal apparatus 73 comprises a severing blade unit which can be adjusted radially in relation to the centre axis 37 of the material roll 3. During use, the severing blade unit preferably extends radially with respect to the centre axis 37 of the material roll 3. The severing blade unit is capable, in particular, of engaging in a severing manner radially from the outside between the material roll 3 and the respective side cover 74 during use. Here, the material roll 3 preferably rotates about its centre axis 37. The severing blade unit is preferably used by the gantry robot 35 as a tool during use. In order to reach the two side covers 74, the gantry robot 35 is moved along the gantry carrier 36. The manipulator is actuated accordingly during the severing operation.

(62) Furthermore, the material roll preparation arrangement 2 comprises a protective plug removal apparatus 75 which is capable of removing protective plugs 76 from the central carrying core 32 (FIG. 5). The protective plugs 76 are arranged in the two ends of the central carrying core 32. They are preferably rotationally symmetrical and sleeve-like. The external shape is in each case complementary with respect to the internal shape of the carrying core 32. The protective plugs 76 close the carrying core 32 partially. The protective plug removal apparatus 75 has a removal cone 77. During use, a tip of the removal cone 77 leads and is moved along the centre axis 37 of the material roll 3 to the respective protective plug 76. For the removal of the respective protective plug 76, the removal cone 77 is introduced, for example, axially from the outside into the protective plug 76, and is pulled axially out of the central carrying core 32 together with the protective plug 76. In the case of an introduction of the removal cone 77 into the protective plug 76, there is preferably a positively locking and/or non-positive connection between the two. The removal cone 77 can be driven rotationally, for example. As an alternative, for example, the protective plugs 76 can be destroyed by machining. The removal cone 77 is preferably used as a tool by the gantry robot 35. In order to reach the two protective plugs 76, the gantry robot 35 is moved along the gantry carrier 36. The manipulator is actuated accordingly in the case of the removal operation.

(63) Moreover, the material roll preparation arrangement 2 has a peeling apparatus 44 (FIGS. 2, 3, 6 and 7A). The peeling apparatus 44 comprises a releasing device 45 with a lifting unit 46 and a severing unit 47, and a spacing mandrel 48.

(65) The severing unit 47 is configured as an (in particular, rotationally drivable) cutting roll. During operation, a cutting axis of the cutting roll extends perpendicularly with respect to the centre axis 37 of the received material roll 3.

(66) The spacing mandrel 48 extends adjacently with respect to, in particular below, the cutting roll. It runs perpendicularly with respect to the cutting axis in the direction of the suction bodies 49, and is capable of engaging under a free material web section 50 of the material web on the edge side. The free material web section 50 adjoins an outer circumference of the material web. One end of the material web is situated at the carrying core 32.

(67) The releasing device 45 is capable of releasing or detaching the end-side material web section 50. During operation, the severing unit 47 severs an adhesive bond of the free material web section 50 from a material web section which is arranged below it. Via the suction bodies 49 and the spacing mandrel 48, the free end-side material web section 50 of the material roll 3 is lifted. Damage of the material web section which is arranged below it can thus be ruled out. The releasing device 45 is preferably used as a tool by the gantry robot 35. In order to reach the adhesive bonds at the two end sides, the gantry robot 35 is moved along the gantry carrier 36. The manipulator is actuated accordingly in the case of the removal operation. The material roll 3 is pivoted accordingly.

(68) Moreover, the peeling apparatus 44 comprises a brush roll 51 which extends horizontally.

(73) A disposal container 60 is arranged downstream of the discharging transport device 56.

(74) The quality testing device 54 tests the unwound material web section 50 for damage. It utilizes, for example, a contour measurement, an ultrasonic sensor, laser or camera technology such as by means of backlight technology or incident light. The material roll 3 is unrolled or unpeeled until a complete revolution thereof has been detected as being free from damage by the quality testing device 54.

(75) The peeling apparatus 44 can be moved horizontally in its entirety, with the result that it can be adapted to different diameters of material rolls 3. The spacing of the peeling apparatus 44 from the receiving device is thus variable. An adjusting unit is favourably provided to this end.

(76) Instead of the peeling apparatus 44, at least one vacuum unit, drawing roll rotating in the opposite direction, or brush can be used as an alternative.

(77) A punching unit 61 with at least one rotationally drivable punching roll, preferably with at least one punching roll pair, is arranged upstream of the disposal container 60 in the discharging direction of the unwound material web section 50, which punching unit 61 is capable of cutting the unwound material web section 50 into longitudinal strips during operation (FIG. 3). During operation, the at least one rotating punching roll exerts a tensile force on the unwound material web section 50 in the direction of the disposal container 60, with the result that the unwound material web section 50 is held under stress and is thus protected against further damage. It is expedient if the punched strips are comminuted further, for example in a shredder, and are thus fed to the disposal container 60.

(78) As an alternative or in addition, the releasing device 45 is capable of severing or removing strapping bands 78 which originally strap or run around the material roll 3 in a ring-like manner on the circumferential side, which leads to a release or detachment of the end-side material web section 50 (FIGS. 7B and 7C). It forms a strapping element removal apparatus. The strapping bands 78 are arranged spaced apart axially from one another and bear tightly on the outside against the material roll 3 or the end-side material web section 50. They hold the material roll 3 together.

(79) During operation, the severing unit 47 severs the respective strapping band 78. Here, the spacing mandrel 48 engages under the respective strapping band 78. The severing unit 47 and the spacing mandrel 48 delimit a severing nip, in which the respective strapping band 78 is severed and is therefore removed from the material roll 3. Here, the suction bodies 49 are not used. To this end, the releasing device 45 is preferably used as a tool by the gantry robot 35. In order to reach the strapping bands 78, the gantry robot 35 is moved along the gantry carrier 36. The manipulator is actuated accordingly in the case of the removal operation.

(80) It is expedient if the releasing device 45 has a strapping band detection device for the detection and location of the strapping bands 78. The strapping band detection device is favourably signal-connected to the gantry robot 35 for the corresponding actuation thereof.

(81) As FIGS. 11 and 12 show, the unwound material web section 50 is assigned a final contour production apparatus 62, in order to produce a defined final contour in the unwound material web section 50 which remains on the material roll 3.

(82) The final contour production apparatus 62 has a clamping device 63 which is arranged downstream of the brush roll 51 and/or the deflection roll 52 in the discharging direction of the material web section 50. The clamping device 63 has a clamping body 70 which can be moved in a guided manner, in particular vertically, and a counter-body 71 which is assigned to the said clamping body 70. The clamping web section 50 can be fixed spatially (FIG. 12) between the clamping body 70 and the counter-body 71 in their clamping position. In the clamping position, the clamping body 70 and the counter-body 71 are arranged directly adjacently with respect to one another with the material web section 50 situated in between, and act in a clamping manner on the material web section 50 such that they lie opposite one another. In a non-clamping position, the clamping body 70 and the counter-body 71 are arranged spaced apart from one another and from the material web section 50. They do not then act on the material web section 50.

(83) Furthermore, the final contour generation apparatus 62 has a cutting device 64 which can be moved in a guided manner and is arranged downstream of the clamping device 63. The cutting device 64 uses the counter-body 71 and, with the latter, configures a cutting nip in a cutting position.

(84) In the clamped state of the material web section 50, the cutting device 64 is actuated (FIG. 12), in order to produce the desired final contour in the unwound material web section 50. In the case of the cutting, the cutting device 64 slides along on the counter-body 71. The final contour is situated in that trailing part of the unwound material web section 50 which remains on the material roll 3. The leading part of the unwound material web section 50 is disposed of.

(85) As FIG. 8 shows, the produced final contour 65 on the material web section 50 can be arcuate. A produced arc is favourably of symmetrical configuration in relation to the material web section 50 or the material web. A head region or tip region which is central in the transverse or width direction of the material web section 50 is leading in relation to the further processing of the material roll 3. The arcuate final contour 65 is suitable, in particular, for manual further processing of the material roll 3.

(86) According to FIG. 9, the final contour 66 is formed by way of a cut which extends rectilinearly, but obliquely with respect to the longitudinal or conveying direction of the material web section 50. The oblique final contour 66 is suitable, in particular, for the manual further processing of the material roll 3.

(87) According to FIG. 10, the final contour 67 is formed by way of two rectilinear part sections 69 which form a tip 68. The tip 68 is favourably of symmetrical configuration in relation to the material web section 50 or the material web. It is leading in relation to the further processing of the material roll 3. The final contour 67 which has a central tip 68 is suitable, in particular, for automatic further processing of the material roll 3.

(88) As an alternative, the final contours 65, 66, 67 are produced by means of the punching unit 61.

(89) By way of a splicing tape attachment apparatus 79, a splicing tape 80 or piece thereof is attached in a sensor-controlled manner adjacently with respect to the produced final contour 65, 66, 67 to the material web section 50 which remains on the material roll 3 (FIGS. 14 and 15). In particular, the position, the angle and the contact pressure of the splicing tape 80 are monitored by sensor, which makes automatic further processing possible. Depending on the required winding direction, the splicing tape 80 is attached on the inner side or on the outer side to the material web section 50. The splicing tape 80 is arranged at a start or leading section of the material roll 3.

(90) The splicing tape attachment apparatus 79 comprises a splicing tape supply roll 81, a splicing tape pressing roll 82 which is arranged downstream of the splicing tape supply roll 81 in the unwinding direction, and a severing tool 83 which is arranged downstream of the splicing tape pressing roll 82 in the unwinding direction.

(91) The splicing tape supply roll 81 contains the splicing tape 80 in a wound-up form. It is mounted rotatably.

(92) The splicing tape pressing roll 82 is likewise mounted rotatably. The splicing tape supply roll 81 and splicing tape pressing roll 82 have rotational axes which run parallel to one another. They preferably extend perpendicularly with respect to the centre axis of the material roll 3.

(93) The severing tool 83 comprises a severing blade 84 which can be moved between a severing position and a rest position, in particular in a linear manner.

(94) In the case of the attachment of the splicing tape 80 to the material web section 50, the splicing tape supply roll 81 is placed onto the material web section 50, with the result that an adhesive surface of the splicing tape 80 bears against the material web section 50. The splicing tape attachment apparatus 79 is then moved at least in regions along the final contour 65, 66, 67, the splicing tape supply roll 81 preferably rotating and unwinding the splicing tape 80. The splicing tape pressing roll 82 presses the splicing tape 80 which bears against the material web section 50 firmly onto the material web section 50. By way of the movement of the splicing tape attachment apparatus 79, the splicing tape pressing roll 82 rotates. In particular, the splicing tape pressing roll 82 bears against an outer severing cover of the splicing tape 80, which severing cover can be removed and originally covers a second outer adhesive surface of the splicing tape 80. In the rest position, the severing blade 84 is arranged spaced apart from the splicing tape 80. In the severing position, the severing blade 84 penetrates the splicing tape 80 with severing thereof when the splicing tape 80 is finally attached. By way of the splicing tape 80, a further finite material web can be connected to the finite material web of the material roll 3 in order to form an endless material web. The splicing tape attachment apparatus 79 is preferably used as a tool by the gantry robot 35. The gantry robot 35 is moved along the gantry carrier 36, preferably to a central region of the material roll 3, for the attachment of the splicing tape 80. The manipulator is actuated accordingly in the case of the attachment operation. The material roll 3 is pivoted accordingly.

(95) Subsequently, the unwound material web section 50 is fixed on the actual material roll 3 by means of a fixing adhesive piece 72, with the result that unintentional lifting of the free end of the material roll 3 is prevented (FIG. 13). The fixing adhesive piece 72 bears in an adhesive manner against a material web section 50 which is arranged below it. The gantry robot 35 (shown in a simplified manner in FIG. 13) is used for the attachment of the fixing adhesive piece 72. To this end, it uses a corresponding fixing adhesive piece attachment tool. The gantry robot 35 is moved along the gantry carrier 36, for example to a central region of the material roll 3, for the attachment of the fixing adhesive piece 72. The manipulator is actuated accordingly in the case of the attachment operation. The material roll 3 is pivoted accordingly. The material roll 3 can thus be transported securely.

(96) As an alternative, for example by way of the splicing tape attachment apparatus 79 which is shown in FIGS. 14 and 15 with the formation of a material web fixing apparatus, an adhesive tape 80 or at least one piece thereof is attached in a sensor-controlled manner adjacently with respect to the generated final contour 65, 66, 67 to the material web section 50 which remains on the material roll 3. In particular, the position, the angle and the contact pressure of the adhesive tape 80 are monitored by sensor, which makes automatic further processing possible. The adhesive tape 80 is arranged at a start or leading section of the material roll 3.

(97) The adhesive tape attachment apparatus 79 comprises an adhesive tape supply roll 81, an adhesive tape pressing roll 82 which is arranged downstream of the adhesive tape supply roll 81 in the unwinding direction, and a severing tool 83 which is arranged downstream of the adhesive tape pressing roll 82 in the unwinding direction.

(98) The adhesive tape supply roll 81 contains the adhesive tape 80 in a wound-up form. It is mounted rotatably.

(99) The adhesive tape pressing roll 82 is likewise mounted rotatably. The adhesive tape supply roll 81 and adhesive tape pressing roll 82 have rotational axes which run parallel to one another. They preferably extend perpendicularly with respect to the centre axis of the material roll 3.

(100) The severing tool 83 comprises a severing blade 84 which can be moved between a severing position and a rest position, in particular in a linear manner.

(101) In the case of the attachment of the adhesive tape 80 to the material web section 50, the adhesive tape supply roll 81 is placed onto the material web section 50, with the result that an adhesive surface of the adhesive tape 80 bears against the material web section 50, and its adjacent end edge protrudes with an adhesive connection to the material web section which is arranged below it on the material roll 3. The adhesive tape attachment apparatus 79 is then moved at least in regions along the final contour 65, 66, 67, the adhesive tape supply roll 81 preferably rotating and unwinding the adhesive tape 80. The adhesive tape pressing roll 82 presses the adhesive tape 80 which bears against the material web section 50 firmly onto the material web section 50 and the material web section which is arranged below it. By way of the movement of the adhesive tape attachment apparatus 79, the adhesive tape pressing roll 82 rotates. In particular, the adhesive tape pressing roll 82 bears against a non-adhesive rear side of the adhesive tape 80. In the rest position, the severing blade 84 is arranged spaced apart from the adhesive tape 80. In the severing position, the severing blade 84 penetrates the adhesive tape 80 with severing thereof when the adhesive tape 80 is attached finally. By way of the adhesive tape 80, the free material web section 50 can be fixed on a material web section which lies below it, which prevents unintentional unwinding of the material web. The adhesive tape attachment apparatus 79 is preferably used as a tool by the gantry robot 35. The gantry robot 35 is moved along the gantry carrier 36, preferably to a central region of the material roll 3, for the attachment of the adhesive tape 80. The manipulator is actuated accordingly in the case of the attachment operation. The material roll 3 is pivoted accordingly.

(102) The expressions “arranged upstream”, “arranged downstream”, “leading”, “trailing” or the like which are used here relate, in particular, to the conveying direction of the associated web or of its section.
