A slide fastener comprises a pair of tape-like units each secured to one edge of an article whose edges are to be connected by movement of a slider along the units. Each tape-like unit comprises a row of interconnected coupling elements formed by a synthetic-resin monofilament, each coupling element having an eye or loop-shaped portion deformed to constitute the coupling head which can be received between coupling heads of the other row. From the eye-forming monofilament segments, shanks extend across the tape-like unit and are received in pockets of a multiplicity of longitudinal threads (e.g. as the weft of a weave in which the longitudinal threads form the warp, or in courses of the warp knit in which the longitudinal threads are loop chains). The slider has a pair of channels which merge into a common channel, the transition zone between the pair of channels and the common channel being superimposed to press the coupling heads of one row between the coupling heads of the other generally perpendicularly to the slide-fastener plane. |
