ABSTRACT:
A slide-fastener stringer comprises, for each slide-fastener half, a support tape formed with a sewing strip and a facing strip, both having warp threads and a base weft thread extending all across both strips while a binding weft thread extends all across the sewing strip while engaging with reverse loops, the continuous coupling element which can be formed of a synthetic-resin monofilament. The monofilament may be of the helical-coil type in which each turn of the coil is formed with a coupling head adapted to fit between the coupling heads of an opposing coupling element, limbs or shanks connected to the head and connecting portions or bights connecting a limb of one head to a limb of the next head. The limbs against the support tape are provided with transverse grooves receiving an insertion thread which is woven into the tape.
