A woven stringer tape of a slide-fastener half, designed to support a row of thermoplastic coupling elements molded around a carrier cord adjoining a longitudinal edge of the tape, has warp threads parallel to that edge traversed by a weft thread looped about the cord, at least two of these warp threads close to the core and in mutual phase opposition consisting of thermoplastic monofilaments with a melting point lower than that of the coupling elements. Upon the molding of the latter, these two thermoplastic warp threads are partially melted along surface portions in contact with the coupling elements so as to form notches in which the coupling elements positively engage for a firm anchorage to the fabric. |
