<p>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 flamentary 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 connection portions and blends into adjacent two loops to pull the connecting portions of the element inwardly toward each other. 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. The invention avoids difficulties experienced in prior art, namely the formation of irregular bends in the tape distorting the shape of the element.</p> |
