ABSTRACT:
A device for manufacturing a multilayered tube formed of paper webs that are provided with transverse perforations at identical distances, wherein sections of the tube are torn off in order to manufacture paper bags, includes at least one perforating knife that is arranged in the machine frame and fastened to a rotating shaft. The perforating knife provides the paper webs with transverse perforations, and the radial distance between the perforating knife and the shaft may be altered so as to adjust the format of the bags. In addition, the device includes transverse gluing cylinders that are arranged in the machine frame, which are provided with transverse gluing bars and which cooperate with devices for applying glue. Also included is a longitudinal gluing roller that applies glue which forms a longitudinal adhesive seam onto the edges of the paper webs which are laterally offset with respect to one another and guided together via guide rollers before the paper webs are folded into a tube. In order to make it possible to reequip the device in a simple and rapid fashion such that tube sections of different lengths may be manufactured, four carriers for perforating knives that may be selectively fastened onto the carriers are arranged on the shaft at identical angular distances. The carriers are provided with devices for adjusting their radial distance from each shaft.
