ABSTRACT:
A slide-fastener stringer is made by feeding a warp of warp filaments in a longitudinal warp direction to a weaving location, feeding to an edge of the warp at the weaving location a coupling coil formed by a multiplicity of turns each forming a coupling head directed transversely away from the warp and a coupling part extending at least generally longitudinally, feeding to the weaving location within the coil a thick filler cord, and weaving through the warp filaments and around the coupling parts and filler cord between the heads at least one weft filament. In order to maintain coil pitch exact both the coil and filler cord are positively engaged at a location immediately longitudinally upstream of the weaving location with a feed and guide element so as to retard advance of the feed and guide element and create in both the coil and in the filler cord a tension between the feed and guide element and the weaving location.
