Hereinafter, the first splicing device 3 will be described in more detail by way of example. As mentioned, the remaining splicing devices 4, 5, 6 and 53 are identical or essentially identical, so that the subsequent explanations regarding the first splicing device 3 are essentially analogous to these.

The first splicing device 3 comprises a base frame 57 having a base frame base 58, a base frame stand 59 and a base frame beam 60. The base frame pedestal 58 is fixed to the floor. To the base frame pedestal 58, the basic rack stand 59 is fixed. The basic rack stand 59 extends substantially vertically to the floor. The base rack support 60 is on attached to the base frame base 58 opposite end of the basic frame stand 59 and extends substantially parallel to the ground.

The second roll-off device 11 is designed in accordance with the first roll-off device 9. The rotation axes 62 of the roll-off devices 9, 11 are parallel to each other.

The finite first material web 7 is fed via a first feed roller 64 and the finite second material web 63 originating from the material roll 10 is fed via a second feed roller 64 to a cutting and connecting device 65. The feed rollers 64 are rotatably mounted on roller support arms 66 which are pivotally mounted to the base rack support 60 above the material rollers 8 and 10, respectively, for tensioning the finite material webs 7,63.

The cutting and joining device 65 serves to produce the endless first material web 17 from the finite material webs 7, 63. The cutting and joining device 65 has a first preparation unit 108, a second preparation unit 109 , a first connecting unit 110, a second connecting unit 111, a table unit 112, and a guide 113.

The first preparation unit 108 is according to Fig. 4 on the base frame support 60 substantially above the first material roll 8, whereas the second preparation unit 109 in the region of the second material roll 10 is disposed on top of the base frame support 60. Between the preparation units 108, 109, the guide 113 extends substantially parallel to the floor, in the guide 113, the preparation units 108, 109 are displaced and the table unit 112 is also displaced therebetween.

The connecting units 110, 111 are arranged along the guide 113 spaced from each other. They are arranged on the base frame support 60 above the guide 113.

The preparation units 108, 109 are identically constructed and arranged so as to be displaceable symmetrically in the guide 113 with respect to a vertically running symmetry plane. Due to the identical construction of the preparation units 108, 109, only one preparation unit 108, 109 will be described below.

The cross-cutting device 67 of the second connecting unit 111 and its pressure roller 115 are immediately adjacent to the guide 113 on the base-frame support 60th fixed so that the adhesive rollers 114 of the preparation units 108, 109 and the table unit 112 in the guide 113 on the second connecting unit 111 are guided past. The pressing roller 115 of the second connecting unit 111 forms in the in Fig. 4 shown position of the adhesive roller 114 of the second preparation unit 109 with this one connection gap for passing the to be joined finite material webs 7, 63 and an adhesive tape which can be attached to it by the second preparation unit 109.

The table unit 112 cooperates with the preparation units 108, 109 and / or with the connecting units 110, 111 and is independently displaceable along the guide 113. In Fig. 4 the cutting and connecting device 65 is in an inactive state. In this state, the finite first material web 7 is passed only through the cutting and joining device 65, whereas the finite second material web 63 is held in a waiting position by the cutting and joining device 65, so that this if necessary with the finite first material web 7 to the endless first material web 17 is connectable.

The cutting and connecting device 65 is arranged downstream of a first deflecting roller 70 which is rotatably mounted on the base frame support 60 in the region of the second material roll 10 above. The endless first material web 17 is guided around the first deflection roller 70.

The first deflecting roller 70 is followed by a second deflecting roller 71, which is rotatably mounted on a storage trolley 72. The storage trolley 72 is disposed in the region of an upper end of the base rack support 60 opposite the basic rack stand 59 and is displaceable in a storage trolley guide 73 which extends parallel to the floor and a Verlageings Rail of storage wagon 72 pretends. The storage cart guide 73 extends substantially along the entire base rack support 60. The storage cart 72 is displaceable between a first end position and a second end position. It is displaceable in opposite directions of displacement 74, 75. In the first end position, the storage cart 72 is disposed adjacent a spout 76 of the endless first web of material 17 while the storage cart 72 is spaced at the second end position. In Fig. 4 the storage cart 72 is shown in an intermediate position between the two end positions.

For deflecting the endless first material web 17 in the region of the outlet 76, a third deflecting roller 77 is rotatably arranged on the base frame carrier 60.

The third deflecting roller 77 is followed by a fourth deflecting roller 78, which is rotatably mounted between the second deflecting roller 71 and the third deflecting roller 77 on the storage trolley 72. The second and fourth deflection rollers 71, 78 always run parallel to one another.

The base rack support 60 has two opposing side walls 79, 80 extending parallel to one another. The side walls 79, 80 are spaced from one another.

The storage cart 72 is disposed between the side walls 79, 80. Each side wall 79, 80 carries a guide portion 81 for guiding the storage trolley 72. The guide portions 81 are opposed to each other and parallel to each other. They together make up the store car guide 73. The storage carriage guide 73 extends above the guide 113 and parallel to this.

The storage cart 72 has two opposite side portions 82, which are identical and mirror-image. He forms a rigid entity. The second deflecting roller 71 and the fourth deflecting roller 78 are rotatably supported in the side members 82 about their longitudinal center axes 83 and 84, respectively.

For displacing the storage trolley 72 along the storage trolley guide 73, the first splicing device 3 has an adjustment arrangement 85. The adjustment arrangement 85 comprises two transmission chains 86, which are of identical construction and run separately from one another. Each transfer chain 86 is endless and includes a plurality of chain links 87. A transfer chain 86 extends inwardly adjacent to the side wall 79, while the other transfer chain 86 extends inwardly adjacent the other side wall 80 ,

Adjacent to the third deflecting roller 77, between the side walls 79, 80, a coupling rod 88 of the adjusting assembly 85 extends. The coupling rod 88 is supported in and bounded by the side walls 79, 80 It is virtually the displacement path 73 of the storage cart 72. It is rotatable about its longitudinal center axis 93 and rotatably driven. The coupling rod 88 and the second deflection roller 71 as well as the fourth deflection roller 78 preferably extend substantially always parallel to each other.

Adjacent to the side walls 79, 80, the coupling rod 88 carries two chain wheels 89 which are fitted to the transmission chains 86 and are rotatably connected to the coupling rod 88. Each transmission chain 86 is guided around a chain wheel 89 so that the transmission chains 86 are in operative connection with the coupling rod 88 via the chain wheels 89.

Furthermore, each transmission chain 86 is guided around a deflection wheel 90 which is rotatably mounted on the respective side wall 79 and 80, respectively. The deflection wheels 90 virtually limit the displacement path 73 of the storage carriage 72 there.

Each side portion 82 of the storage cart 72 is fixedly connected to the adjacent arranged transfer chain 86 via a respective driver 91.

The coupling rod 88 is rotatably driven about its longitudinal center axis 93 by an adjusting drive 92 of the adjusting arrangement 85. In use, rotation of the coupling rod 88 results in rotation of the chain wheels 89 and thus actuation of the transmission chains 86. By operation of the transmission chains 86, the storage carriage 72 is moved along the track 91 by the dogs 91 Storage Cart Guide 73 shifts.

The adjusting drive 92 has a flexible coupling 94 which on the one hand allows a rotational drive of the coupling rod 88 and on the other hand an angular offset of the coupling rod 88.

The coupling rod 88 is rotatably supported by a pendulum ball bearing 95 in or on the side wall 80. It is rotatably mounted in or on the other side wall 79 via another pendulum ball bearing 96.

On the pendulum ball bearing 96 engages a tilting drive 97, which includes a housing 98 and a displaceably guided in the housing 98 tilt rod 99. For tilting the coupling rod 88, a long hole 100 is arranged in the side wall 79, which extends in the displacement direction 74 and 75, respectively. By retracting or extending the tilting rod 99, the coupling rod 88 is tiltable. Tilting of the coupling rod 88 results in a corresponding tilting of the storage trolley 72. During tilting, the coupling rod 88 moves along the long hole 100.

In the neutral position of the coupling rod 88, this extends perpendicular to the side walls 79, 80 and substantially to the endless first material web 17 and its transport direction. The same applies to the deflection rollers 71, 78.

When the coupling rod 88 is tilted, it extends obliquely with respect to the side walls 79, 80 and the endless first material web 17 or their transport direction. The same applies to the deflection rollers 71, 78 and the storage trolley 72nd

Below, the operation of the first splicing device 3 will be described in more detail. The finite first material web 7 is unrolled from the first material roll 8 and fed via the first feed roller 64, where the finite first material web 7 is deflected by about 90 °, to the cutting and joining device 65 , The same applies essentially to the finite second material web 63, which is deflected by the second feed roller 64.

After the cutting and connecting device 65, the endless first material web 17 is guided around the first deflection roller 70 and deflected there by approximately 180 °. The endless first material web 17 is then guided to the second deflection roller 71, where it is again deflected by about 180 °. After the second deflection roller 71, the endless first material web 17 is guided around the third deflection roller 77, where it is again deflected by about 180 °. Subsequently, the endless first material web 17 is guided around the fourth deflection roller 78, where it is again deflected by about 180 ° and is guided to the outlet 76. At the exit 76, the endless first material web 17 leaves the first splicing device 3.

Due to the continuous rolling of the finite first material web 7, the first material roll 8 ends after a certain time, so that the finite second material web 63 has to be connected to the finite first material web 7.

In detail, for this purpose, the finite second material web 63 is manually fed by the operator of the corrugated board plant, preferably over its entire material web width, with a one-sided adhesive before being fed to the second feed roller 64 at its web start. Band provided.

Thereby, the endless first material web 17, which is now in communication with the finite second material web 63, released. The second preparation unit 109, whose adhesive roller 114, the finite second material web 63 is promoted, is in the guide 113 in a position mirroring the position of in Fig. 4 shown displaced behind the second feed roller 64.

Due to the known length of the finite second material web 63, the first splicing device 3 recognizes when the second material roll 10 comes to an end. Before this occurs, the prepared finite first material web 7 is joined to the finite second material web 63. This is done in the same way as the previously explained change of the finite material webs 7, 63.

For this purpose, in detail, the finite first material web 7 before being fed to the first feed roller 64, also at the beginning of its web, is manually transferred by the operator of the corrugated board plant, preferably via their entire material web width, provided with a one-sided adhesive tape.

The finite first material web 7 is then guided via the first feed roller 64 to the first preparation unit 108 displaced above the first feed roller 64 for this process. After fixing the finite first material web 7 to the adhesive roller 114 of the first preparation unit 108, preferably on the outer shell thereof, the first preparation unit 108 in the guide 113, the mirror image of the in Fig. 4 shifted position of the second preparation unit 109 toward the second feed roller 64 moves.

Subsequently, the unrolling process of the second unrolling device 11, that is the finite second material web 63, is stopped.

By shifting the storage cart 72 into the second end position, the loops 70, 71, 77, 78 form the loops formed by the endless first material web 17, so that the endless first material web 17 continues to rotate first splice device 3 leaves without interruption or is conveyed without interruption.

The endless first material web 17 is conveyed by means of the pressure roller 115 of the first connecting unit 110, this pressure roller 115 being fed by a pneumatically operated pivot unit (not shown) to the adhesive roller 114 of the first preparation unit 108 is guided against the adhesive end of the single-sided adhesive tape which is attached to the web beginning of the finite first material web 7 and is located at the predetermined position on the adhesive roller 114 of the first preparation unit 108 pressed. This will connect the endless first material web 17 with the finite first material web 7. The supply of the finite second material web 63 to the endless first material web 17 is stopped.

To create a second cutting edge, the table unit 112 in the guide 113 is displaced such that a cutting edge of the cutting blade 69 displaced by a linear unit (not shown) of the cross-cutting device 67 of the first connecting unit 110 for completely separating the finite second material web 63 from the endless first material web 17 into a recess provided in the table unit 112 for the cutting blade 69 of the cross-cutting device 67 of the first joining unit 110 entire width can dip.

After the cutting operation to completely separate the endless first material web 17 and the finite second material web 63, the cutting blade 69 of the cross-cutting device 67 of the first connecting unit 110 is returned to its original position and thereupon Subsequently, the pressure roller 115 of the first connecting unit 110 moves back to its original position. As a result, the endless first material web 17, which is now in connection with the finite first material web 7, released. The first preparation unit 108, via whose adhesive roller 114 the finite first material web 7 is conveyed, is moved in the guide 113 to a position equal to that in FIG Fig. 4 shown position, behind the first feed roller 64 moves.

The first cut edge and the second cut edge are formed complementary to each other and complement each other substantially overlap-free. The cut edges can be profiled and finger-like each other. When creating the second cut edge, second cut edge projections and cut edge depressions have been created.

The produced endless first material web 17 thus has the connection region defined by the adhesive band, in which the finite material webs 7, 63 mesh with one another along their transport directions in the manner described.

After joining the finite material webs 7, 63, the finite second material web 63 is unrolled from the second material roll 10. During the unwinding of the finite second web of material 63, the storage cart 72 is displaced as far as possible, but not completely, to the other end position to form loops of the endless first web of material 17, since this storage path in addition to the regulation of the Web tension is used.

If the endless first material web 17 and the endless second material web 18 are arranged laterally offset from one another in the first corrugated cardboard production device 1, a corresponding tilting of the coupling rod 88 and thus also of the storage wagon 72 takes place. to compensate for the offset between the endless first web of material 17 and the endless second web of material 18. Tilting of the storage cart 72 has resulted in a change in the course direction of the endless first material web 17.

For detecting a course of the endless first material web 17, a first sensor arrangement 101 is provided between the first splicing device 3 and the first corrugated cardboard production device 1, more precisely between the first deflecting roller 19 and the first Corrugated cardboard production device 1, is arranged. The first sensor arrangement 1 is in signal connection via a first signal line 102 to an information processing device 103.

A second sensor arrangement 104 is associated with the endless second material web 18.
