PCT No. PCT/DE80/00016 Sec. 371 Date Oct. 21, 1980 Sec. 102(e) Date Sep. 25, 1980 PCT Filed Feb. 20, 1980 PCT Pub. No. WO80/01794 PCT Pub. Date Sep. 4, 1980.For designing an automatic reel change system for use in connection with the processing of a web from a reel (7, 8) on a reel support (2), the web being sheeted in a transverse cutter (3), the invention takes the form of a system which makes do with a very narrow web part having a greater-than-normal thickness, but, nevertheless, safely joining the two webs together; the reel stand (or support) (2) has support parts (9 and 10) for at least two reels (7 and 8), from which, on reel change-over, a double web, made up of old web (11) (web coming to an end) and new web (12) (web from the new reel), may be taken, and near the path of the web, a cutting station (14) is present, able to be put into operation for cutting through the double web, a joining station (15), able to be put into operation the necessary time after operation of the cutting station (14), for joining the end (30), produced on cutting operation, of the old web (11) with the leading edge (31), produced on cutting operation, of the new web (12), using an adhesive strip (23) overlapping the ends as a join, an advancing unit (13) which is placed before said cutting station, said advancing unit (13) being designed for acting on the double web run through it and being put into operation at least between the cutting and joining operations, and near the joining station (15) for the new web (12) and old web (11), pulling parts (16), able to be put into operation separately, which are designed for taking effect on the front ends of the cut off runs, placed in front of and after the position of cutting, of the two webs in question. |
