Abstract: In a zip fastener comprising coupling member rows being formed of one continuous monofilament each, the coupling members of which consist of a folded S-shaped meandering profile, after conducting the according manufacturing process, the folded S-shaped meandering profile forming the coupling members of each coupling member row is connected in a weft thread manner with two strips of textile knitted fabrics forming a carrying tape, and the two strips of textile knitted fabrics forming the carrying tape are areally superimposed on each other with their leading edges being aligned.
Abstract: A method and apparatus for simplifying the production of closing members from a continuous tape having supporting hooks or eyes, for use in undergarments and the like. Zones of separation are produced between individual closing members by ultrasonic linear welding as the tape is advanced in steps.
