<p>In the construction of a slide fastener a stringer is made as follows. A helical row of slide fastener elements is fed parallel to warp threads for forming a supporting tape weft threads are inserted to weave a supporting tape and to join the helical row of slide fastener links to a supporting tape. The helical row of slide fastener links is held in a zero plane and during the weaving is guided along a straight line. Joining warp threads are warped in equal numbers above and below the zero plane so as to be spaced from the row of slide fastener links and disposed before the coupling surfaces thereof. The warp threads of the woven supporting tape are warped on the other side of the row of slide fastener links below the zero plane. The joining warp threads and the warp threads of the woven supporting tape are formed into separate sheds. Two weft threads for the supporting tape arc simultaneously pushed through the sheds both above and below the zero plane, respectively, in such a manner that the two upper weft threads pass at least through the sheds formed by the joining warp threads and the lower weft thread pass through the sheds formed by the joining warp threads and the warp threads of the supporting tape thus pulls the forming warp threads from one side of the row into the convolutions of the helical row by means of the weft threads. Selvages are formed from the warp threads at the respective edges of the woven fabric.</p> |
