ABSTRACT:
A woven slide fastener stringer has a stringer tape including a weft thread woven in double picks with warp threads and having loops disposed along a longitudinal edge of the tape, a core thread extending through the weft loops, and a filamentary coupling element having turns each including a pair of limbs between which the core thread is disposed and connecting portions extending between adjacent two limbs. Each of the double picks has a portion extending around one of the connecting portions and between the one connecting portion and the core thread, and blending into adjacent two weft loops, thereby fastening the coupling element securely in position. Such a stringer is manufactured using a pair of monofilament and weft carriers insertable into and withdrawable out of warp sheds, a mandrel vertically shiftable into various shed positions, and in some embodiments means operatively coupled with the carriers for vertically displacing the threads and monofilament.
