Method of producing a slide-fastener stringer on a needle loom

Abstract From the Canadian patent

A method of producing a continuous slide fastener strip by weaving on an automatic needle loom warp yarns for, support tape and warp yarns for tying-in being guided to form sheds, weaving needles being used to pick weft yarns for the support tape and a plastics monofilament yarn. A weaving needle which reciprocates continuously between an outside position and an inside position is operative to loop the plastics monofilament yarn around a former for forming coupling members, a row thereof being formed continuously from the monofilament yarn, the coupling members of such row each comprising a coupling head and connected arms which form a coupling loop and being joined together by connecting …
