ABSTRACT:
A slide-fastener stringer half has an elongated warp-knitted tape having a pair of opposite faces and a pair of opposite longitudinally extending edges. The tape is knit with a plurality of chained warp yarns each forming a respective longitudinally extending loop chain or pillar defining a respective longitudinally extending wale, a first weft filament laid into and extending over two of the chains at one of the edges of the tape, a group of second weft yarns lapped into the chains across the full width of the tape, and a group of third weft yarns laid into all of the chains except that chain immediately at the one edge. A continuous mono-filamentary coupling element having a succession of turns is secured to one face of the tape along the one edge by stitching which overlies the turns, extends through the tape, and has a needle thread on the other face of the tape between two of the chains at the one edge.
