[0002] This application claims priority to German Patent Application No. DE 10 2022 209 598.7, the contents of which are incorporated herein by reference. Technical Field

[0003] The present invention relates to an assembly for producing single-sided laminated corrugated sheet webs (particularly endless corrugated sheet webs). Background Technology

[0004] Assembly systems for producing single-sided laminated corrugated sheet widths are known in the prior art. When changing the corrugating rollers, prolonged downtime of the assembly frequently occurs. In particular, pressure band interference repeatedly occurs when a new upper corrugating roller or a new set of corrugating rollers is installed in the assembly for producing single-sided laminated corrugated sheet widths. Summary of the Invention

[0005] The objective of this invention is to overcome the shortcomings of existing technologies. In particular, an assembly for producing single-sided laminated corrugated sheet webs should be provided, which allows for particularly reliable and user-friendly corrugating roll replacement. Corrugating roll replacement should also be performed very efficiently or quickly.

[0006] According to the invention, this objective is achieved by an assembly for producing single-sided laminated corrugated sheet webs, comprising a first corrugating roll and a second corrugating roll for producing corrugated webs; an adhesive applicator for applying adhesive to the crests of the corrugations of the corrugated web; a pressure band assembly including a pressure band for pressing a cover web against the glued crests of the corrugated web, the corrugated web resting against the first corrugating roll in some areas; and a pressure band engagement assembly including a pressure band engagement device and at least one displacement device, the pressure band engagement device engaging the pressure band during corrugating roll replacement to minimize and eliminate at least one of the downward sag of the pressure band adjacent to the pressure band engagement device, and the at least one displacement device being connected to the pressure band engagement device to shift the pressure band engagement device between a pressure band engagement position and an idle position. The essence of the present invention is a pressure band joining device that, at its pressure band joining position, minimizes and eliminates at least one of the downward or downward sag of the pressure band adjacent to the (working) pressure band joining device during corrugating roll replacement, and thus particularly provides the necessary (installation) space for arranging at least one new first corrugating roll or a new set of corrugating rolls in the assembly for producing single-sided laminated corrugated sheet width. It is convenient if the pressure band joining device can push and / or pull the pressure band upward or hold it in the joining area at the pressure band joining position. In particular, the pressure band joining device can correspondingly, preferably directly engage when at least one new corrugating roll is arranged on the pressure band. It is preferably capable of tensioning the pressure band at the pressure band joining position.

[0007] It is advantageous if the pressure belt joining device can operate at least partially, preferably fully automatically. This allows for particularly simple and quick replacement of the corrugating rollers. Therefore, it simplifies the maintenance, repair, and / or cleaning of the components used to manufacture single-sided laminated corrugated sheet webs. The pressure belt joining device, or its displacement path / distance, is preferably settable or adjustable in its angle relative to the horizontal plane, which allows, for example, to accommodate different corrugating rollers. Alternatively, the device may be immovable or (arranged as) fixed.

[0008] In the pressure band engagement position, the pressure band engagement device preferably engages the pressure band over at least one width region, preferably over the entire width. For example, it is rigid at least in the pressure band engagement position. The pressure band engagement device is preferably elongated and preferably extends in a straight line. For example, it includes at least one pressure band engagement element, such as a pressure band engagement rod, pressure band engagement strip, pressure band engagement cord, etc. At least one pressure band engagement element has, for example, a circular or angular (such as rectangular) outer profile. Advantageously, the movement of the pressure band engagement device is guided. Advantageously, the pressure band engagement device is infinitely movable. For example, the length of the movement path or the movement distance can be influenced or predetermined. For example, the engagement force of the pressure band engagement device at the pressure band is adjustable or predetermined. In the idle position, the pressure band engagement device is arranged at a distance from the pressure band.

[0009] The pressure band coupling device and at least one displacement device are directly or indirectly connected to each other. For example, there may be a rigid or hinged connection between them. It is useful if the pressure band coupling device is connected to the displacement device at each end.

[0010] At least one displacement device includes, for example, a displacement actuator, which is preferably designed as an electric, pneumatic, and / or hydraulic displacement actuator. The pressure band engagement device can also be operated manually or by hand. At least one displacement device is then designed accordingly.

[0011] The corrugating rolls are preferably arranged in pairs. They preferably form a set of corrugating rolls. The corrugating rolls are mounted such that they can be rotated or driven to rotate in the corrugating position and form a corrugating gap for producing the corrugated width. They can be replaced individually, but preferably together. It is useful if the first corrugating roll forms the upper corrugating roll and the second corrugating roll forms the lower corrugating roll.

[0012] The pressure belt device preferably includes at least two deflecting rollers, and advantageously, an endless pressure belt is guided around the deflecting rollers. The pressure belt preferably has a uniform width in its width or transverse direction. It can be driven circumferentially. For example, it is made of a metallic material. Alternatively, the pressure belt is made of plastic or a flexible material such as rubber. It is useful if at least one deflecting roller can tilt to change the path of the pressure belt in its width direction and / or can be displaced at its distance from the other deflecting roller to change the tension of the pressure belt.

[0013] The gluing equipment includes, for example, a glue tray and a gluing roller for applying glue from the glue tray to the corrugated fabric web. Furthermore, the gluing equipment preferably includes at least one glue metering roller or extrusion roller associated with the gluing roller for metered glue application.

[0014] Further advantageous embodiments of the invention are described below.

[0015] The following embodiments result in a particularly simple and functionally reliable pressure band engagement device: wherein the at least one shifting device enables the pressure band engagement device to be linearly shifted between the pressure band engagement position and the idle position, and wherein the at least one shifting device is designed as a linear shifting device and preferably is variable in length. The at least one shifting device is designed, for example, as a cylinder-piston shifting device, a spindle shifting device, etc. For example, it is telescopic. It is advantageous if the pressure band engagement device can extend perpendicularly to its longitudinal direction or shift along its longitudinal axis. It is preferably shiftable at an angle to or perpendicular to the horizontal plane.

[0016] The following embodiment allows for trouble-free operation of the pressure belt device: the pressure belt engagement device (particularly completely) is arranged outside the pressure belt device. Therefore, the pressure belt device can be designed to be relatively simple. Advantageously, the pressure belt engagement device is completely arranged outside the pressure belt device. It is preferably located entirely outside the space surrounded or spatially defined by the pressure belt. It is advantageous if the pressure belt engagement device is at least partially, preferably completely, arranged below the pressure belt device, particularly below the adjacent deflector rollers of the pressure belt device, especially when the pressure belt engagement device is in its idle position.

[0017] This component is particularly designed to prevent failure, wherein the pressure belt engagement device engages the lower section of the pressure belt from below in its pressure belt engagement position. The pressure belt engagement device engages the pressure belt particularly between the deflection rollers from below and the outside, i.e., especially in the area where the lower section of the pressure belt typically sags or sinks during roving roller replacement due to the absence of the first roving roller at that time. Therefore, it is preferably engaged at a distance from the upper section of the pressure belt. There, the lower section can be relatively easily moved from the bottom to the top or held at the top.

[0018] The following embodiment again allows for a particularly simple corrugating roll replacement: during the corrugating roll replacement, at least the first corrugating roll is lowered relative to the working corrugating position. Therefore, interference between the first corrugating roll and the pressure band device can be minimized or eliminated. It is useful if the first and second corrugating rolls are replaced together during the corrugating roll replacement. The assembly for generating a single-sided laminated corrugated sheet width preferably includes corresponding lifting devices for lowering at least the first corrugating roll relative to the working corrugating position, and preferably lowering both the first and second corrugating rolls.

[0019] The following embodiments also allow for trouble-free replacement of the first corrugating roller, preferably both the first and second corrugating rollers: at least one coating roller of the coating equipment can be displaced relative to the first corrugating roller and is arranged with an offset relative to the working coating position during corrugating roller replacement. It would be even more convenient if the coating equipment could be displaced or reset accordingly. Advantageously, the assembly for producing single-sided laminated corrugated sheet widths has corresponding guiding or displacing devices.

[0020] The pressure band engagement device produced by the following embodiment is particularly reliable in function: the pressure band engagement device is arranged at the glue applicator, particularly at its glue tray and / or the glue applicator housing. The engagement force ratio is particularly advantageous when the pressure band engagement device engages the pressure band from the glue applicator.

[0021] When the pressure band engaging position shifts between the engagement position and the idle position, the angle relative to the horizontal plane formed by the movement trajectory traced by the pressure band engaging device is preferably adjustable, such as manually and / or by means of an actuator, such as an electric, pneumatic and / or hydraulic actuator, wherein the angle is between 2° and 20°, preferably between 4° and 10°, between 10° and 40°, preferably between 15° and 35°, or between 50° and 8°, preferably between 55° and 75°.

[0022] When the pressure band engagement device engages the pressure band from the component frame, the following embodiments can also produce an advantageous engagement force ratio: wherein the pressure band engagement device is arranged adjacent to the adhesive applicator at the component frame, and wherein the pressure band engagement device is arranged at the height of the second ribbed roller at the component frame, and in particular, the pressure band engagement device is arranged at the component frame on the side of the second ribbed roller opposite to the adhesive applicator.

[0023] The corrugating roll changing device according to the invention makes the assembly for producing single-sided laminated corrugated sheet webs particularly convenient and efficient. For example, the corrugating roll changing device can be used to replace at least the first corrugating roll. Preferably, the corrugating roll changing device can be used to replace both the first and second corrugating rolls together. Usefully, the corrugating roll changing device includes a corrugating roll box or cassette that can be moved, particularly in a guided manner, between the corrugating roll operating position (i.e., corrugating position) and the corrugating roll storage position, and is capable of accommodating at least one corrugating roll to be replaced. The corrugating roll storage position can be located inside or outside the assembly for producing single-sided laminated corrugated sheet webs. The corrugating roll changing device ensures space-saving storage of at least one additional corrugating roll. It guarantees quick, standardized, and therefore easily repeatable replacement of at least one corrugating roll. The setup time is particularly short. The corrugating roll changing device preferably includes at least one changing drive. The latter can be configured to be manually or electrically driven. Attached Figure Description

Detailed Implementation

[0039] exist Figures 1 to 3 , Figure 8 , Figure 9 The image fully illustrates assembly 1 for producing single-sided laminated corrugated sheet webs, which is part of a corrugated sheet facility (not shown). Cover webs 2, particularly endless cover webs, are fed by a cover web unwinding device (not shown) of the corrugated sheet facility, and strip material 3, particularly endless strip material, is fed by a strip material unwinding device (not shown) of the corrugated sheet facility.

[0040] The assembly 1 for producing a single-sided laminated corrugated sheet web includes a first or upper corrugating roller 6 rotatably mounted about a first rotation axis 5, and a second or lower corrugating roller 8 rotatably mounted about a second rotation axis 7, for producing a corrugated sheet web 4 with corrugations from a strip material 3. Figure 3AThe rotation axes 5 and 7 are parallel to each other, and preferably horizontally parallel. They extend perpendicular to the conveying direction 9 of the strip material 3 or the corrugated width 4. The corrugating rollers 6 and 8 form roller bites or corrugating bites 10 for guiding the strip material 3 through and corrugating it.

[0041] The assembly 1 for producing single-sided laminated corrugated sheet widths includes a fixed frame 11. Furthermore, the frame 11 has two separate supports 12 that are supported on a floor (such as a hallway floor).

[0042] The two corrugating rollers 6 and 8 can be moved vertically together. For this purpose, the assembly 1 used to produce single-sided laminated corrugated sheet widths has a lifting device.

[0043] To connect the corrugated strip 4 to the cover strip 2 to form a single-sided laminated corrugated sheet strip 13, the assembly 1 for producing the single-sided laminated corrugated sheet strip has an adhesive applicator 14 located downstream of the bite 10 relative to the strip material 3 or the corrugated strip 4. The adhesive applicator 14 further includes a glue tray 15, an adhesive applicator roller 16 partially arranged in the glue tray 15, and an adhesive metering roller 17 associated with the adhesive applicator roller 16. The adhesive applicator roller 16 is arranged between the first corrugating roller 6 and the adhesive metering roller 17. The adhesive applicator roller 16 and the adhesive metering roller 17 are rotatably mounted in the adhesive applicator housing 18 of the adhesive applicator 14. Optionally, they are rotatably mounted, for example, in the sidewall of the glue tray 15. Their axes of rotation are parallel to each other and parallel to the axes of rotation 5 and 7 of the corrugating rollers 6 and 8.

[0044] The glue application equipment 14 can be completely perpendicular to the first ribbed roller 6 in the working glue application position. Figure 3 ) and non-working ribbed roller replacement position ( Figure 8 Move horizontally between ).

[0045] To pass and apply adhesive onto the corrugated fabric web 4, the applicator roller 16 forms a gap 19 with the first corrugating roller 6 in its working applicator position, thus creating an adhesive gap or applicator gap. By rotating the applicator roller 16, which is immersed in adhesive, adhesive (not shown) in the adhesive tray 15 is applied to the free crests of the corrugations of the corrugated fabric web 4, which is being conveyed in the conveying direction 9. The adhesive metering roller 17 is arranged adjacent to but spaced apart from the applicator roller 16 and is used to form a uniform adhesive layer on the applicator roller 16. Gap and / or force control can be performed. In the case of force control, the applicator roller 16 is always (with a defined force) against the corrugated fabric web 4. In the case of gap control, the gap between the adhesive metering roller 17 and the applicator roller 16 is used to set the adhesive application. The adhesive metering roller 17 is driven to rotate. The applicator roller 16 and the adhesive metering roller 17 are driven to rotate by at least one drive belt.

[0046] Then, the corrugated web 4, coated with adhesive, is engaged in the assembly 1 for producing single-sided laminated corrugated webs with the cover web 2 conveyed in the conveying direction 20 to obtain single-sided laminated corrugated web 13. To press the cover web 2 against the coated corrugated web 4 (wherein the corrugated web 4 rests against the first corrugating roller 6 in certain areas at the top), the assembly 1 for producing single-sided laminated corrugated webs has a modularly designed pressure belt device 21. The pressure belt device 21 is arranged downstream of the corrugated web 4 relative to the adhesive applicator 14, the seam 10, and the gap 19.

[0047] The pressure belt device 21 has a first deflecting roller 22 and a second deflecting roller 23, and an endless pressure belt 24 guided circumferentially around the deflecting rollers 22 and 23. The pressure belt 24 is deflected by the deflecting rollers 22 and 23. The deflecting rollers 22 and 23 can be driven to rotate. For example, the second deflecting roller 23 can be equidistant from the first deflecting roller 22. It can also be tilted relative to the first deflecting roller 22. The second deflecting roller 23 is therefore designed as a belt tension and belt running adjustment roller. A reverse design is possible. When the second deflecting roller 23 is not tilted, the rotation axes of the deflecting rollers 22 and 23 are parallel to each other and parallel to rotation axes 5 and 7.

[0048] The first deflecting roller 22 is arranged above the first flexing roller 6 or the glue coating device 14. The second deflecting roller 23 is arranged substantially beside the first flexing roller 6. It is arranged substantially on the side of the first flexing roller 6 away from the glue coating device 14.

[0049] When producing single-sided laminated corrugated sheet width 13, the first corrugating roller 6 engages from below in the space between deflecting rollers 22 and 23. The lower band 25 of the pressure band 24 (also referred to as the lower extension or lower free section of the pressure band 24) is deflected by the first corrugating roller 6 and pressed against the opposing upper band 26 of the pressure band 24 (conversely referred to as the upper band or upper free section of the pressure band 24). The lower band 25 and the upper band 26 are (substantially) arranged opposite to each other and extend (vertically) spaced apart. They have opposite directions of movement during operation. The lower band 25 presses against the cover band 2 from the outside or above with its outer / lower side, and the cover band 2, in turn, presses against the corrugated sheet width 4 from above, which is provided with adhesive and rests on the first corrugating roller 6 at the top.

[0050] Roughing rollers 6 and 8 are arranged in roughing roller box 27. Figure 9The corrugating rollers 6 and 8 can be shifted, and in particular moved, between the corrugating roller operating position and the lateral corrugating roller storage position. In the corrugating roller operating position, the corrugating rollers 6 and 8 are in their working corrugating positions. In the corrugating roller storage position, they are at a distance from the working corrugating positions and are outside the assembly 1 used to produce single-sided laminated corrugated sheet webs. Therefore, the corrugating roller box 27, which is currently in use, together with the corrugating rollers 6 and 8, can be replaced by a corresponding new corrugating roller box 28, which can be shifted, and in particular moved, accordingly. The new corrugating roller box 28 includes / carries two correspondingly arranged new corrugating rollers 29 and 30, which differ, for example, from the corrugating rollers 6 and 8 of the previously used corrugating roller box 27, particularly in terms of diameter and / or corrugation. The corrugating rollers 6, 8, 29, and 30 can be axially shifted, respectively. In particular, the new corrugating roller box 28 stores the new corrugating rollers 29 and 30 required for the effective operation of the assembly 1 used to produce single-sided laminated corrugated sheet webs. The ribbed roller boxes 27, 28, and preferably other ribbed roller boxes are advantageously housed in at least one ribbed roller box (not shown).

[0051] A pressure band joining device 31 is arranged at the adhesive applicator 14. The pressure band joining device 31 includes two shifting devices 32, which preferably have identical structures and are arranged in pairs. Each shifting device 32 has an outer body 33, which is arranged laterally or mounted, for example, in a fixed or rotatable manner, outside the glue tray 15, the glue tray sidewall, and / or the adhesive applicator housing 18. For example, each outer body 33 is designed in the form of a housing. The glue tray 15, the glue tray sidewall, and / or the adhesive applicator housing 18 are located / arranged between the shifting devices 32 and / or the outer bodies 33.

[0052] Each shifting device 32 also has an elongated movable body 34 that can be moved or displaced axially or linearly relative to the associated outer body 33, particularly guided by the outer body 33. Each movable body 34 may, for example, retract into and / or extend from the associated outer body 33. For example, it is rod-shaped. The movable body 34 is guided out from the side of the respective outer body 33 adjacent to or facing the first roving roller 6.

[0053] The pressure band engaging device 31 also includes an engaging rod 35, preferably circular in cross-section and extending in a straight line. The engaging rod 35 is, for example, parallel to the first axis of rotation 5 or perpendicular to the circumferential or circumferential direction of the pressure band 24. It extends horizontally and is arranged on the free end of the moving body 34, which extends from the outer body 33. The engaging rod 35 travels between the moving bodies 34. Advantageously, the engaging rod 35 can rotate or be driven to rotate about its longitudinal axis.

[0054] Advantageously, the pressure band joining device 31 can be integrated or incorporated into the actuation unit of the assembly 1 or the corrugated board facility for producing single-sided laminated corrugated board widths, particularly into the control and / or regulation unit.

[0055] The operation of component 1, used for producing single-sided laminated corrugated sheet widths, is explained in more detail below.

[0056] For example, such as Figure 3 As shown, when component 1 is running to produce a single-sided laminated corrugated sheet width, the corrugating rollers 6, 8 of the currently used corrugating roller box 27 or corrugating roller group are in their working corrugating positions and are able to produce corrugated sheet width 4.

[0057] The glue coating equipment 14 is in the working glue coating position, so that the glue coating roller 16 can apply glue to the corrugated material web 4 in a dosage manner.

[0058] The lower belt 25 rests against the top of the conveyed cover strip 2 in the area of ​​the first corrugating roller 6 and presses the latter against the glued corrugated strip 4 conveyed there, thereby forming a single-sided laminated corrugated strip 13.

[0059] When producing single-sided laminated corrugated sheet width 13, the pressure band joining device 31 is in its idle position (see also). Figure 4 , 5 The connecting rod 35 is arranged below the first deflecting roller 22 and at a certain distance below the pressure band 24. It is (basically) arranged laterally next to the first ribbed roller 6 and above the coating roller 16. The moving body 34 retracts into the outer body 33, in particular, retracts completely.

[0060] Double-sided laminated corrugated sheet widths can be produced from single-sided laminated corrugated sheet width 13 in a corrugated sheet facility.

[0061] The following describes the replacement of the previously used corrugating roller box 27 with a new corrugating roller box or a new corrugating roller cassette 28. Preferably, the assembly 1 for producing single-sided laminated corrugated sheet width is in a stationary state.

[0062] First, the pressure band 24 is not tensioned. Therefore, the second deflector roller 23 moves in the same direction as the first deflector roller 22.

[0063] The adhesive applicator 14 is moved horizontally from the working adhesive applicator position away from the first corrugating roller 6 and perpendicular to the first corrugating roller 6 to a non-working corrugating roller replacement position. At the same time, the pressure band engagement device 31 is also moved accordingly. Then, the previous corrugating roller box 27, together with the corrugating rollers 6 and 8, is lowered or moved downward from the corrugated position toward the ground by means of a lifting device.

[0064] After or during the relocation of the ribbed roller box 27 together with the ribbed rollers 6, 8 and / or the relocation of the adhesive applicator 14, the moving body 34 extends linearly from the outer body 33 uniformly, for example, completely together, such that the engaging rod 35 contacts the lower belt 25 of the pressure band 24 between the deflecting rollers 22, 23 from below and outside, and thus presses the lower belt 25 upward in the direction of the upper belt 26 or keeps it upward (see also...). Figure 6 , 7 8). The pressure band 24 can be tensioned. The engaging rod 35 moves diagonally upward above the first ribbed roller 6. It moves below the first deflector roller 22. The engaging rod 35 is capable of rotating about its longitudinal axis during extension or movement, which prevents damage to the pressure band 24. It then engages directly at the bottom of the pressure band 24 and is perpendicular to its circulation direction in a linear manner across its entire width. In particular, it prevents the lower band 25 from sagging between the deflector rollers 22, 23. In doing so, the pressure band 24 is preferably stationary. When the engaging rod 35 extends, each outer body 33 forms an angle w relative to the horizontal plane H, for example, a preset angle w, which is between 2° and 20°, preferably between 4° and 10°. It is advantageous if the angle w can be adjusted, for example, manually and / or by a separate actuator or motor.

[0065] Subsequently, the corrugating roller box 27, which had been active until this point, along with the corrugating rollers 6 and 8, was completely moved laterally out of the assembly 1 used to produce single-sided laminated corrugated sheet widths. Figure 9 The lower belt 25 maintains a certain distance from the first corrugating roller 6. A new corrugating roller box 28 and corrugating rollers 29 and 30 are laterally inserted from the other side into assembly 1 for producing single-sided laminated corrugated sheet widths. It moves below the pressure belt device 21.

[0066] The connecting rod 35 retracts evenly again in the opposite direction. This effectively places the pressure belt 24 from above onto the new upper treading roller 29. The new upper treading roller 29 and the lower belt 25 approach each other.

[0067] The new flaring roller box 28 moves upward together with the flaring rollers 29 and 30 to its working flaring position.

[0068] Then, the pressure band 24 is tensioned. This is achieved by uniformly shifting the second deflector roller 23 away from the first deflector roller 22 and / or by shifting the new ribbed roller box 28 upward.

[0069] The adhesive applicator 14 moves again toward the new upper ribbed roller 29 to its working adhesive applicator position. At the same time, the pressure belt coupling device 31 also moves accordingly. In its ribbed position, the new upper ribbed roller 29 once again presses the lower belt 25 upward onto the upper belt 26.

[0070] Then, the strip material 9 and the covering material 2 are fed in again. Corrugated board production can then restart.

[0071] The pressure belt coupling device 31 can discharge the bolstering roller box 27, including the bolstering rollers 6 and 8 that have been used so far, without damaging or destroying the pressure belt 24 in the area of ​​the lower belt 25. Conversely, a new bolstering roller box 28 can be inserted together with the bolstering rollers 29 and 30 without interfering with or damaging the pressure belt 24 in the area of ​​the lower belt 25.

[0072] Below, refer to Figures 10 to 12 The second embodiment is described. Compared to the aforementioned embodiments explicitly mentioned herein, the outer body 33 is arranged or mounted, particularly directly, on the bracket 12 of the frame 11 adjacent to the adhesive applicator 14, for example, on the inner side. The outer body 33 is thus located between the respective bracket 12 and the adhesive applicator 14. They are arranged laterally beside the first ribbed roller 6. In the contracted state, the connecting rod 35 is arranged (substantially) above the gap 19 between the first ribbed roller 6 and the adhesive applicator 16. The rod is located below the first deflector roller 22 and maintains a certain distance from the pressure band 24. Figure 10 ).

[0073] When the glue applicator 14 moves from the working glue applicator position to the non-working ribbed roller replacement position, the pressure band coupling device 31 remains unaffected.

[0074] When the moving body 34 ( Figure 11 , Figure 12 As it extends, the engaging rod 35 moves again above the first flexing roller 6 and below the first deflecting roller 22 to the lower belt 25 between the deflecting rollers 22 and 23. The engaging rod 35 moves obliquely upward and then engages with the lower belt 25 from below and outside, as in the first embodiment. It pushes the lower belt 25 upward or holds it there. When the engaging rod 35 extends, the outer body 33 forms an angle w relative to the horizontal plane H, which is between 10° and 40°, preferably between 15° and 35°, and is preferably adjustable.

[0075] After the ribbed roller is replaced, the connecting rod 35 can retract evenly in the reverse direction.

[0076] Below, refer to Figure 13 The third embodiment is described. Compared to the two aforementioned embodiments explicitly referred to therein, the outer body 33 is arranged or mounted at the height of the second tack roller 8 on the side of the second tack roller 8 facing away from the glue applicator 14, particularly directly on the support 12 of the frame 11, for example, on the inner side. Thus, each outer body 33 is (substantially) arranged below the second deflection roller 23.

[0077] When the glue applicator 14 moves from the working glue applicator position to the non-working ribbed roller replacement position, the pressure belt coupling device 31 remains unaffected.

[0078] During extension, the engaging rod 35 is guided past the second deflecting roller 23. It is also guided past the first ribbed roller 6. It moves diagonally upward. In its engaged position, as in the first embodiment, the engaging rod 35 engages the lower band 25 of the pressure band 24 from below on the outside and pushes it upward or holds it there. As the engaging rod 35 extends, each outer body 33 forms an angle w with the horizontal plane H, which is between 50° and 80°, preferably between 55° and 75°, and is preferably adjustable.

[0079] After the ribbed roller is replaced, the connecting rod 35 can retract back in the opposite direction and evenly.
