SLIDING CLASP FASTENER STRINGER AND METHOD FOR ITS MANUFACTURE

摘要

A slide-fastener stringer has a tape formed from a ground weave with double wefts interwoven with a warp and a coupling element disposed along the edge of the tape and held thereto by binding warps. The coupling element is of the type in which a synthetic resin monofilament is coiled to form coupling heads whose shanks are disposed one above the other so that they have a common projection in the slide fastener plane. The shanks are connected to those of successive heads by bights. The coupling warp comprises a plurality of warp yarns whose patterns are offset lengthwise by at least one pick and which each passes over two coupling elements, between the next coupling element and a ground double weft and under a double weft between coupling elements in a repeating pattern. Double weft disposed between consecutive coupling members are drawn upwardly beyond the median plane of the coupling element as ground-weft padding loops.
