ABSTRACT:
A slide fastener stringer of the woven type in which the tape has a ground weave provided with warp threads and a weft formed of double-weft passes on a needle loom. The coupling element is of the continuous, preferably coil, monofilament synthetic-resin type in which the two shanks of each coupling member are formed as a double-weft insertion connected in the weaving process with the ground weave of the tape. According to the invention, the warp sheds interwoven the double-weft of the ground weave are separate from the warp yarns interwoven with the double-weft insertions of the monofilament and are spaced or offset therefrom in a direction orthogonal to the slide fastener plane. Some warp yarns are interwoven with the double-weft of the ground weave and run over the shanks of monofilament.
