From the prior art, it is known through public prior use to introduce material webs into machining / processing arrangements. This is generally done manually or manually. Furthermore, the prior art teaches the manual or manual removal of separating covers from double-sided adhesive pieces that are attached to material webs in order to connect them to one another. This is often associated with a not inconsiderable expenditure of time and is often not carried out with particular care.

the EP 1 752 403 A1 discloses a generic device for guiding a web from a first position to a second position, in particular from an unwinding position to a winding section of a roll winding device, with an auxiliary device. The auxiliary device comprises a first holding means which is held in a carrier on both sides of the web. A second holding element is attached to at least one carrier and is at a distance from the first holding element in a receiving state having. The two holding elements are pressed against one another by the threaded web in such a way that they clamp them between them. The carriers with the holding elements located between them can be moved from the first position to the second position by a guide system. The auxiliary device has a drive so that it can be guided from the unwinding station to the winding station. The guiding of the web is often unsatisfactory, which can cause the device to malfunction.

From the DE 197 24 123 A1 a device for transferring a threading strip or a material web within a machine for producing and / or processing the material web from a transfer area into a transfer area along a web path is known. The threading strip or the material web, consisting for example of paper or cardboard, is guided, for example, over rollers, device surfaces and / or on belts, the arrangement of which determines the path of the web. A guide, which has at least one guide element, is assigned to a receiving device. According to a preferred embodiment, the guide element can be driven by means of a drive so that the receiving device can be moved along the guide path.

The material web splice arrangement 1 comprises at least one material web clamping device 78 for holding the material web 3, 4, 7 to be drawn in by clamping ( Figures 11-14 ).

The material web clamping device 78 has a profile-like rigid cross member 79 which extends in the transverse direction of the material web 3, 4, 7 to be drawn in and protrudes laterally in the transverse direction of the material web 3, 4, 7 to be drawn in. The cross member 79 engages in mutually opposite guide elements and is thus guided displaceably perpendicular to its extension. The cross member 79 can be displaced along the link guide 49 and is thus able, depending on its position, to carry out translatory and / or arcuate movements or the like. It extends perpendicularly between the opposing guide elements.

The cross member 79 has a material web receiving opening 80 which is open opposite to the feed direction or transport direction 37. It is essentially U-shaped.

The link guide 49, the material web clamping device 78 and the coupling chains 87 together with their displacement drive (s) are part of a material web pull-in device.

The operation of the material web splice arrangement 1 is described below by way of example. This is done by Fig. 1 went out. at Fig. 1 the finite first material web 4 is unrolled from the first roll of material 5 and thus conveyed. It was drawn into the material web splice arrangement 1 by means of the material web pull-in device with the finite first material web 4 being unrolled from the first material roll 5, which will be described in detail below.

The finite first material web 4 is guided to the cutting connection device 17 via the first feed roller 16, where the finite first material web 4 is deflected. It is passed between the pressure rollers 33, 36, which are spaced apart from one another, and rests against them on the circumferential side in some areas.

Downstream of the cutting and connecting device 17, the finite first material web 4 or the endless material web 3 is introduced from above into the threading assistant assembly 38 and wraps around its two conveyor rollers 39, 40, resting against the conveyor rollers 39, 40. The threading assistance arrangement 38 favorably supports the transport of the finite first material web 4 or the endless material web 3 and is driven accordingly.

Then the finite first material web 4 or the endless material web 3 is guided around the first deflection roller 41 on the storage carriage 42. Then the finite first material web 4 or the endless material web 3 is guided around the stationary second deflecting roller 45. Then the finite first material web 4 or the endless material web 3 is guided around the third deflection roller 46 on the storage carriage 42. Then the finite first material web 4 or the endless material web 3 is guided around the stationary fourth deflecting roller 47. Then the finite first material web 4 or the endless material web 3 is guided around the fifth deflection roller 48 on the storage carriage 42. Then the finite first material web 4 or the endless material web 3 leaves the material web splice arrangement 1 via the material web outlet 44.

The finite first material web 4 or the endless material web 3 extends largely adjacent to the link guide 49.

The storage trolley 42 is arranged adjacent to the material web outlet 44. The first vacuum roller 25 is arranged at a distance from the first transport roller 27. The table device 23 is located adjacent to the connecting devices 21, 22. It is arranged at a distance from the preparation devices 19, 20.

The cutting and connecting device 17 is in its inactive state. In this state, the finite first material web 4 or the endless material web 3 is merely passed through the cutting and connecting device 17.

at Fig. 1 the finite second material web 7 was drawn into the material web splice arrangement 1 by means of the material web pull-in device with the finite second material web 7 being unrolled from the second material roll 8. The material web splice arrangement 1 has received the second material roll 8 and also the first material roll 5 after alignment in their circumferential direction in an exactly defined starting position by means of the material roll preparation arrangement 2.

In order to pull in the finite second material web 7, the clamping bar 84 is in its clamping position and is pivoted in the direction of the material web holding web 82 while the finite second material web 7 is clamped. The finite second material web 7 to be drawn in is thus arranged between the holding web 82 and the clamping bar 84 and held in a clamping manner. It penetrates the material web receiving opening 80. The coupling chains 87 are motorized synchronously drawn in, so that the cross member 79 together with the fixed, finite second material web 7 is drawn along the link guide 49 as far as the second preparation device 20. The cross member 79 is pulled around the transport roller 28 so that it faces the second vacuum roller 26. Due to the unwinding direction of the second roll of material 8, the finite second material web 7 enters the link guide 49 via the free second feed inlet 67.

The second output 69 of the input-side second guide device 63 and the second input of the second guide arch device 70 are arranged adjacent to one another, so that the finite second material web 7 is able to pass from the input-side second guide device 63 into the second guide arch device 70 during the drawing-in process. The second exit end 72 of the second curved guide device 70 and the second connection 74 of the essentially straight, second guide device 73 are arranged adjacent to one another, so that the finite second material web 7 is capable of moving from the second curved guide device 70 into the essentially straight, second guide device 73 during the drawing-in process to get. The second preparation device 20 together with the second guide arch device 70 have been correspondingly displaced along the guide 24 for this purpose.

As Fig. 2 illustrated, the table device 23 then moves along the guide 24 to the second preparation device 20 for a splicing process held clamped. In particular, the finite second material web 7 between the second Transport roller 28 and a holding element 88 of the table device 23 held with deformation of the same. The table device 23 and the second preparation device 20 assume a holding position.

The table device 23 then moves along the guide 24 to the second preparation device 20. The table device 23 and the second preparation device 20 together with the second guide arch device 70 move together along the guide 24 in the direction of the second vacuum roller 26, which in turn moves in the direction of the second preparation device 20 moves. When the second transport roller 28 and the second vacuum roller 26 are arranged adjacent to one another, the second output 69 of the input-side second guide device 63 and the second input of the second guide arch device 70 are arranged separated from one another or at a distance from one another. The second exit end 72 of the second curved guide device 70 and the second connection 74 of the essentially straight second guide device 73 are arranged separated from one another or at a distance from one another ( Fig. 3 ).

The second transport roller 28 and the second vacuum roller 26 are then driven in opposite directions in rotation in such a way that the finite second material web 7 is conveyed back against its actual feed direction and a double-sided adhesive splice 89 arranged at the end of the finite second material web 7 between one by the second transport roller 28 and the second vacuum roller 26 is formed gap. The splice piece 89 is adhesively connected to the finite second material web 7 with an inner adhesive surface. The splice piece 89 faces the second vacuum roller 26 with its detachable, non-adhesive separating cover 90 and rests against the latter with the separating cover 90. The second vacuum roller 26 is active and sucks the separating cover 90 of the splice piece 89 is attached to the separating cover 90 of the splice piece 89 by the negative pressure it generates, thus removing it from the actual splice piece 89, exposing an outer adhesive surface of the splice piece 89 opposite the inner adhesive surface. The second transport roller 28 and second negative pressure roller 26 are part of a separating cover removal device.

The second preparation device 20 and the table device 23 then travel in the coupled state along the guide 24 in the direction of the first preparation device 19 or to the first connecting device 21, the finite second material web 7 being held clamped between the table device 23 and the second transport roller 28 . The second preparation device 20 and the table device 23 move away from the second vacuum roller 26 ( Fig. 5 ). The second transport roller 28 is blocked in its rotation.

The rotation of the second transport roller 28 is then released again. In particular, by displacing the table device 23 and the second transport roller 28 as a unit, the second transport roller 28 is pivoted in such a way that the splice piece 89 reaches an upwardly facing splice position.

As Fig. 5 , 6th show, the second transport roller 28 is moved under the first connecting device 21, so that the splice piece 89 faces the first connecting device 21. The endless material web 3 or finite first material web 4 is pressed against the adhesive splice piece 89, which faces the first pressure roller 33, by moving the first pressure roller 33 of the first connecting device 21. This results in an adhesive connection of the endless material web 3 or finite first material web 4 with the finite second material web 7. The supply of the finite first material web 4 to the endless material web 3 is stopped. The finite first material web 4 is separated from the endless material web 3 by means of the first cutting knife 32.

By moving the storage carriage 42 away from the material web outlet 44, the loops formed by the endless material web 3 are broken so that the endless material web 3 remains the material web splice arrangement 1 without interruption or is conveyed without interruption.

at Fig. 8 the finite second material web 7 is now unrolled from the second material roll 8. The first roll of material 5 is now prepared for later unrolling in a manner analogous to the previous description. The drawing of the finite first material web 4 into the material web splice arrangement 1 takes place essentially analogously to the material web drawing-in device.

As Fig. 9 shows, for a splicing process, essentially analogously to the previous description, a splice piece 89 arranged on the finite first material web 4 is adhesively connected to the endless material web 3 or finite second material web 7, so that the finite first material web 4 is adhesively connected to the endless material web 3 connected is. The supply of the finite second material web 7 is now stopped.

The first output 56 of the input-side first guide device 50 and the first input 58 of the first guide arch device 57 are arranged adjacent to one another, so that the finite first material web 4 is capable of moving from the input-side first guide device 50 into the first guide arch device 57 during the drawing-in process. The first exit end 59 of the first curved guide device 57 and the first connection 61 of the essentially straight first guide device 60 are arranged adjacent to one another, so that the finite first material web 7 is capable of moving from the first curved guide device 57 into the essentially straight first guide device 60 during the drawing-in process to get. The first preparation device 20 together with the first guide arch device 57 have been correspondingly displaced along the guide 24 for this purpose.

If the material web splice arrangement 1 is already in operation and a material web 3, 4 or is unrolled or conveyed, the new, finite material web 4 or 7 is only fed via the material web feed device as described as far as the respective transport roller 27 or 28 led.

If, on the other hand, there is still no material web in the material web splice arrangement 1, the respective finite material web 4 or 7 is completely inserted into the material web splice arrangement 1 up to its material web outlet 44 or into an adjacent production arrangement or by means of the material web pull-in device . -device retractable.

The first output 56 of the first guide device 50 on the input side and the first input 58 of the first arcuate guide device 57 are then arranged adjacent to one another, so that the finite first material web 4 is able to move from the first guide device 50 on the input side into the first arcuate guide device 57 during the drawing-in process to get. The first exit end 59 of the first curved guide device 57 and the first connection 61 of the essentially straight first guide device 60 are arranged adjacent to one another, so that the finite first material web 7 is capable of moving from the first curved guide device 57 into the essentially straight first guide device 60 during the drawing-in process to get. The first preparation device 20 together with the first guide arch device 57 have been correspondingly displaced along the guide 24 for this purpose. Alternatively, the second output 69 of the input-side second guide device 63 and the second input of the second guide arch device 70 are arranged adjacent to one another, so that the finite second material web 7 is able to pass from the input-side second guide device 63 into the second guide arc device 70 during the pull-in process. The second exit end 72 of the second curved guide device 70 and the second connection 74 of the essentially straight, second guide device 73 are arranged adjacent to one another, so that the finite second material web 7 is capable of moving from the second curved guide device 70 into the essentially straight, second guide device 73 during the drawing-in process to get. The second preparation device 20 together with the second guide arch device 70 have been correspondingly displaced along the guide 24 for this purpose.

The coupling chains 87 are drawn in synchronously by a motor, so that the cross member 79 together with the fixed, finite second material web 7 is drawn along the link guide 49 as far as the material web outlet 44 or beyond it.

The material web clamping device 78 is preferably automated or motorized into its starting position for receiving the respective finite Material web 4 or 7 relocated. To accommodate the respective finite material web 4 or 7, the holding web 82 engages under the respective finite material web 4 or 7 arranged. The material web 4, 7 penetrates the material web receiving opening 80.

When the cross member 79 reaches a correct position in relation to the finite material web 4, 7 or its end, the material web detection element delivers a corresponding electrical trigger signal which causes a, preferably motorized, displacement of the clamping bar 84 into its clamping position. The correct position of the cross member 79 in relation to the finite material web 4, 7 or its end is preferably achievable, since the material web splice arrangement 1 receives the material roll 5, 8 in an aligned or precisely defined starting position and thus already knows where it is The end of the respective material web 4, 7 is located on the material roll 5, 8. Subsequently, the cross member 79 is displaced by means of the coupling chains 87 into its desired position while the respective finite material web 4 or 7 is drawn in. A fully automated take-up of the roll of material 5, 8 is possible. Likewise, a fully automated drawing-in of the material web 4, 7.

The control or actuation of the individual units, such as preparation devices 19, 20, connecting devices 21, 22, material web pull-in device and / or separating cover removal device, is preferably carried out by at least one corresponding electrical or electronic actuation or control unit.

The endless material web 3 is fed together with a further endless material web to a corrugated cardboard production device for producing a corrugated cardboard web laminated on one side. This comprises a corrugating device with rollers for producing a corrugated sheet having a corrugation from one of the endless sheets of material. To connect the corrugated sheet to a smooth sheet from the other endless material sheet, the corrugated cardboard production device has a glue application device which applies glue to tips of the corrugation of the corrugated sheet. To press the flat sheet against the corrugated sheet provided with glue, the corrugated cardboard production device has a pressing module, whereby the corrugated sheet, laminated on one side, is created from the corrugated sheet and the flat sheet. Alternatively, the material webs can be used in reverse.

In the following, with reference to the Figures 15 to 18 a second embodiment of the material web holding device described. Identical parts are given the same reference numerals as in the previous embodiment, the description of which is hereby explicitly referred to. Structurally different, but functionally identical parts are given the same reference numerals with an "a" after them.

In comparison with the previous embodiment, the material web holding device is not designed here as a material web clamping device 78, but as a material web suction device 78a. The material web suction device 78a has a cross member 79a which essentially encloses an interior space and is designed, for example, as a rectangular profile body. Opposite flow openings 91 are formed in the cross member 79a.

The cross member 79a is in flow connection with a suction source 92. In the active state of the suction source 92, the material web 4, 7 to be drawn in is sucked onto the cross member 79a and rests firmly against it in the area of the flow openings 91 adjacent to the material web 4, 7 to be drawn in.

The function of the material web suction device 78a or the corresponding material web pull-in device is essentially analogous to that of the material web clamping device 78.

The expressions “upstream”, “downstream”, “input side”, “output side” or the like used here relate in particular to a conveying direction of an associated material web.
