Device for roll change and cross cutting of moving webs "with multiple weighing devices.

In the case of multiple winding devices, it is important to be continuous To quickly transfer the delivered webs from the finished reel to the empty reel at high speed, otherwise the speed of the swaying process must be reduced or interrupted, leading to unclean application, wrinkling, extension of working hours and hay adjustment which leads processing machines upstream of the multiple winding devices.

The known automatic cross-tendon cutting and applying devices are not able to do so at high speeds without a transverse fold (application fold ')' when inserting the goods to be weighed to work; furthermore, when cutting off, a saw cut is created. The transverse fold (application fold) can be used in sensitive Materials cause markings that usually go through several wrapping layers and thereby at the beginning of the winding result a few meters as a reject or loss of the winding material.

In Figs. 1 and 2 of the drawing, one of the best-known systems for automatic roll change with cut-off and application process shown schematically. They show an empty roll 1 in the operating position. On the representation the full role in the acceptance position has been waived. From Figs. 1 and 2 it can be seen how the disadvantageous ^ transverse folds of the wound material in the case of sensitive winding material Cut-off and application process forms..TJm the empty roll 1 is in the operating position, the winding material 2 out, the runs over the rollers 8 and 9 on the full roll, not shown. For better wrapping around the empty roll, it is tight

a contact roller 3 brought up. A fixed knife and a pivotable knife 5 are in the cutting position. A arranged on a pivot lever 6 brush 7 is at the moment swiveled against the winding material during cutting. "

In JLbb. 2 the Wiekelgut 2 has already been cut through, with the rest of the end of the full roll is not shown and the new beginning of the winding material is detected by the brush 7. Due to the long end, the beginning turns over as fold 1o the brush. When moving the pivot lever 6 and brush 7, the fold 1ο is turned over until it is between Contact roller 3 and roller 1 is detected as a kink 11. When using an air nozzle tube instead of the brush 7 Experience has shown that the new beginning wrinkles in the same way.

To avoid these difficulties, according to the invention, a wide, coarse-toothed saw blade is inserted into the current winding material knocked in, since it serves as the baffle at the same time as the new one The beginning of the winding material between an empty roll and contact roll or a contact conveyor belt partially wrapping around the empty roll leads . Since the saw blade can be brought very close to the empty roll, there is no long tip and the new beginning of the weighed goods lies against the empty roll without any cross folds.

The furnace will now be explained with reference to Figs. 3 to 6. Figs. 3 and 4 show the running of the web and the application process on the empty roll when using a contact roller, Fig. 5 and 6 when using a contact conveyor belt.

Fig. 3 shows an empty roll 1 of a multiple winding device, around which the winding material 2 is guided. A contact roller 3 and the deflection roller 8, from which the winding material over the roller 9 is guided to the full roll, not shown, ensure that the weighing goods are smoothly adhered to the empty roll 1. On a pivot lever 6 there is a wide, coarse-toothed saw blade 12. A lay-on roller 13

serves "with smooth and brittle winding material 2 to the first Hold the turns firmly on the roll 1. By the pivoting movement of the pivot lever 6 with the saw blade 12 into the path of the material to be weighed 2, it is separated by the saw blade 12.

Fig. 4 shows the separate path of the weighing product 2, with the Eestende of the full Eolle, not shown, is fed via the guide rollers 8 and 9 and the new beginning after the cutting by the saw blade 12 is guided by this itself between the contact roller 3 and the roller 1 until the beginning detected by the supplied Wiekelgut and comes to the Eolle 1 for winding. After this door aisle, the pivot lever 6 goes with the saw blade 12 back to its original position. It can be placed thereon, as can the contact roller 3 and the lay-on roller 13. be removed from the winding area of the Eolle 1 so that the Eolle 1 is not hindered when it is wound up and changes the age to free up the position for a new empty owl.

Fig. 5 shows the same device, but instead a contact roller, a contact conveyor belt 14 arranged above the width of the web is used, which is from the empty roll is driven. The winding material 2 wraps around it only slightly the empty owl 1.

Fig. 6 shows the separate path of the winding material 2, with the Eestende of the weighing material of the full roll, not shown is fed via the guide rollers 8 and 9. The new beginning of the product 2 is made after cutting by the saw blade guided by the same until he of the contact conveyor belt and the reel 1 is taken over in the guide until it is grasped at the point 15 by the winding material and on the reel 1 is wound up. After several turns, the contact conveyor belt 14 and the pivot lever 6 with the saw blade 12 are removed removed from their positions so that, as described in Fig. 4, the roller 1 can change its position.
