ABSTRACT:
An apparatus for the application of adhesive coated slips to a moving web or to workpieces being conveyed, and preferably to the drawn up and still open bottoms of bags, consists of pairs of feed rolls for a web of material and means for perforating and tearing off, or means for detaching, the slips from the web of material and of a transfer folding gripper cylinder for receiving and subsequent transfer of the slips or pieces of tube. In order to be able to apply additional slips between an applying folding gripper cylinder (9) for the application of the slips and the transfer folding cylinder (6) there is an intermediate cylinder (7), which with the applying folding cylinder (9) defines a roll nip, into which slips run, which are torn off or otherwise detached along lines of perforations from a second web (10) of material are inserted, and which transfers the slips or pieces of tube which are torn off or otherwise detached from the first and the second web of material in an at least partly overlapping condition to the web or, respectively, workpieces (12) passing through the device.
