<p>A woven sliding clasp fastener stringer tape 30 has a weft thread 35 woven in double picks with warp threads 34 and has loops 36 disposed along the fastener selvedge, a core thread 33 extending through the weft loops 36, and a filamentary coupling element 32 having turns 37 each including a pair of limbs 38, 39 between which the core thread 33 is disposed and connecting portions 41 extending between adjacent two limbs 38, 38 or 39, 39 each of the double picks 35 having a portion 42 extending alternately over or under a connecting portion 41 and between the connecting portion 4 and the core thread 33, thereby weaving the coupling element 32 securely in position. Such a stringer tape is manufactured using an inserter for the monofilament and an inserter for the weft, insertable into and withdrawable out of warp sheds, a mandrel vertically shiftable into various shed positions, around which the monofilament is wrapped, lifters to raise or lower the monofil or core thread to enable the weft to wrap there around and some embodiments have two spaced core threads with a woven portion therebetween. In some embodiments the two inserters are also alternately vertically movable so that they vertically cross each other as they are inserted in the shed and also in some embodiments the far selvedge knitting needle is vertically movable. <IMAGE></p> |
