ABSTRACT:
A slide-fastener stringer is formed by weaving a weft in a warp and simultaneously forming a continuous coupling element along each of the confronting edges of a pair of tapes simultaneously produced by the weaving operation. The synthetic-resin monofilament forming the coupling element is passed around a mandrel between the warp stretches so that the heads of the two coupling elements are produced in interdigitated form. The ground weft yarn is carried from the coupling element side of each set of warps through the shed to the opposite edge of the tape where it is locked into other loops of previous passes of weft by knitting.
