TRAGBAND FUER EINEN REISSVERSCHLUSS

摘要

A slide-fastener support tape is made in a warp-knitting machine which chains a plurality of relatively thin warp yarns to form an array of longitudinally extending and transversely spaced wales. One of the needles of the knitting machine is left empty so as to space the edgemost warp yarn from the other warp yarns by a gap corresponding to the transverse width of one wale. A relatively thick warp yarn is blind-lapped into this gap. A group of first weft yarns is laid into the warp yarns to one side of the thick yarn and a group of second weft yarns is lapped into the warp yarns with loop formations to the other side of the thick yarn. It is also possible to provide a second such thick yarn in the tape, held in place by a group of third weft yarns which are also lapped into the tape.
