Abstract A slide-fastener stringer half comprises a knit tape having a plurality of parallel longitudinally extending wales and a plurality of transversely extending courses, and a monofilamentary coupling element on the tape and having a succession of turns each having a pair of shanks and a coupling head joining the shanks and projecting transversely beyond the longitudinal edge of the tape. The shanks of each turn lie at least in regions adjacent the respective head in a plane generally perpendicular to the tape. The tape comprises at least one warp yarn forming a chain knitted into the tape at every other course and overlying the shanks at the regions adjacent the heads. Thus the shanks are laid into the chains at these regions so that the coupling element is thoroughly integrated into the knit of the tape. The tape itself may be formed of a full-tricot ground. Alternatively the tape can be formed of second weft yarns having open loops at each course and extending transversely each over two respective wales.
A slide-fastener stringer half comprising a full tricot ground knit tape and a monofilament coupling element on said tape having a series of turns each having a pair of shanks and projecting transversely beyond a longitudinal edge of said tape, and securing warp filaments warp-knitted into said tape and overlying said shanks, said turns each comprising a pair of such shanks lying along alternate courses of said tape and said warp filament constituting warp pillars chain-knitted into said tape at the remaining courses.
