The operation of the coupling / decoupling arrangement 76 will be explained in more detail below.

In Fig. 5, the corrugated board manufacturing assembly 1 and the blanket / lamination manufacturing assembly 2 produce independently. In the corrugated board manufacturing assembly 1, the endless double-faced laminated corrugated board web is produced, currency end in the printing line / laminating production system 2, the endless printing web 4, the can be printed by the inkjet printing device 58, and the endless laminating sheet 40 are produced.

The endless laminating web 40 and the endless printing web 4 are in the coupling / decoupling assembly 76 separated from each other in their respective, in the same direction conveying Rich device 81 and 98 conveyed one above the other. They extend in the coupling / decoupling assembly 76 horizontally and in parallel, but spaced from one another.

The endless laminating web 40 passes below the laminating guide roll 80 and the upper Zusammenführwalze 94 and touches them. The laminating guide roll 80 and the upper collating roll 94 guide the endless laminating path 40. The adhesive strip counter roller 85 and the laminating path separating element 90 are each in their upper inactive position. They are spaced from the endless laminating web 40 and arranged above it.

The endless laminating path 40 also extends above and spaced from the first adhesive strip roller 83, the upper perforating roller 105, the upper deflecting roller 111, the laminating separating counter element 146, the first laminating web deflection roller 115 and the second laminating path Printing web deflection roller 122.

The endless printing web 4 touches the top of the web guide roller 97 and the lower merge roller 95. The web guide roller 97 and the lower merge roller 95 lead the endless printing web. 4

The endless printing web 4 extends at a distance above the second adhesive strip roller 100, the lower perforating roller 107 and the printing web separating element 118, which are all in their lower, inactive position.

The endless printing web 4 extends at a distance below the first adhesive strip roller 83, the upper perforating roller 105, the lower deflecting roller 112, the first laminating-web deflection roller 115 and the second laminating-web deflection roller 122. The endless printing web 4 is wound in the printing web take-up device 66. The endless laminating web 40 is passed over the laminating transfer device 3 of the corrugated board manufacturing assembly 1 and connected in the connecting device with the one-sided kaschier th endless corrugated web 6 gluing.

The liner transfer assembly 3 comprises a first deflecting bar 124 and a second deflecting bar 125. The first deflecting bar 124 is disposed in the printing line / laminating manufacturing assembly 2 downstream of the coupling / decoupling assembly 76 with respect to the conveying direction 81 of the endless laminating path 40. It extends horizontally and closes with the present there conveying direction 81 of the endless laminating path 40 at an angle which is 45 °. In the first deflection bar 124, the endless laminating path 40 is deflected by 90 ° and turned 180 °. The endless laminating web 40 thus runs in the skiver web transfer arrangement 3 perpendicular to a catching direction of the paperboard manufacturing arrangement 1.

The second deflecting rod 125 extends parallel to the first deflecting rod 124. It is located within the corrugated cardboard manufacturing arrangement 1. By the second deflecting rod 125, the endless laminating web 40 is deflected by 90 ° in the direction of the corrugated conveying direction and turned by 180 °. The endless laminating web 40 downstream of the second order steering rod 125 in the conveying direction of the adjacent, one-sided laminated endless corrugated cardboard web 6 promoted. The second deflection bar 125 is arranged between the web splicing device 8 and the preheating arrangement 37.

When the endless printing web 4 is to be used as a laminating web in the corrugated cardboard manufacturing arrangement 1, the endless printing web 4 has to be introduced into the corrugated paperboard manufacturing arrangement 1 and, as it were, the inkjet printing device 58 has to be coupled to the corrugated cardboard manufacturing arrangement 1. For this purpose, the first adhesive strip attachment device 82 is put into operation. The adhesive strip backing roll 85 is displaced downwardly toward the first adhesive strip roll 83. In this case, she takes along there with the endless laminating web 40 down, whereby it is lifted off the laminating web-Feitwalze 80 and the upper Zusammenführwalze 94. When the adhesive strip counter roll 85 is displaced downwards, the latter and the first adhesive strip roller 83 are pivoted or rotated in such a way that the counter element 86 and adhesive elements 84 face one another and come to rest on opposite sides on the endless laminating path 40. A first adhesive strip 126 held by the adhesive element 84 is adhesively arranged in the widthwise direction thereof on the side facing the continuous printing web 4 on the endless laminating web 40, that is to say below. For this purpose, the first adhesive strip roller 83 is pivoted or rotated from the adhesive strip receiving position into the adhesive strip transfer position. It acts as an adhesive tape attachment roller. In this case, the adhesive strip counter roller 85 prevents deflection of the endless laminating path 40. The printing path splicing device 44 and the corrugated paperboard production device 1 continue to produce (FIG. 6).

Subsequently, as shown in FIG. 7, the adhesive strip counter roll 85 is again shifted upwards to its inactive position. The first adhesive strip roller 83 is pivoted or turned back into its inactive Stel development. The Zusammenführwalzen 94, 95 are driven together evenly. They are moved together in such a way that the endless laminating web 40 and the endless printing web 4 in the first adhesive strip 126 touch each other, whereby they are coupled to one another by means of the first adhesive strip 126.

In addition, the liner separator 89 is put into operation. The Kaschierbahn- separating element 90 is moved to its lower release position. There, it interacts with the laminating separating element 92 with separation of the endless laminating path 40.

Subsequently, as shown in FIG. 10, the liner-pressure-sheet merger 93 is operated. The Zusammenführwalzen 94, 95 are moved together evenly. The endless loose liner sheet 40 is there bonded by means of the second adhesive strip 127 with the endless printing web 4.

The endless laminating web 40 rests against the upper deflecting roller 111, the first laminating-web deflection roller 115 and the second laminating-web-deflecting roller 122 at the top.

The endless printing web 4 is at the bottom of the lower guide roller 112, the first Kaschierbahn- pressure web deflection roller 115 and the second Kaschierbahn-pressure web deflection roller 122 at. Subsequently, the take-up web 129 coming from the printing web take-up device 66 is adhesively connected to the endless printing web 4 by means of the third adhesive strip 128 (FIG. 11).

As shown in FIG. 12, the original continuous printing web 4 tears downstream of the laminating web-assembling device 93 at the perforation produced by the perforating device 104. The Zusammenführwalzen 94, 95 are then again auseinan dergefahren (Fig. 13). The corrugated board manufacturing assembly 1 and the inkjet printing device 58 are decoupled. The endless laminating web 40 is used again in the corrugated paperboard manufacturing arrangement 1.
