发明名称 Process for producing bags with folded over and secured handles by a fold-over rod extending at a right angle to the direction of transport
摘要 The handles of bags, provided with legs, are cemented to both sides of the opening sides of the bags. The handles are U-shaped handles made of strip-shaped material. Parts of the handles are folded over onto the side walls of the bags and fastened with adhesive spots to the side walls of the bags or to the non-folded over segments of the legs. After the legs have been glued to the continuously conveyed bags, the handle parts are folded over onto the side walls of the bags around prerupture lines of the legs in the direction of transport. The handle parts are folded over by at least one fold-over rod extending at a right angle to the direction of transport.
