A method of manufacturing slide fastener stringers having a row of continuous coupling elements which is spirally coiled and woven into the fabric tape simultaneously with the weaving of the latter. There is provided a shuttle for carrying an element-forming filament which is interwoven with warp yarns forming the tape edge and looped over a mandrel wire located adjacent the tape edge by reciprocal, transverse movement of the shuttle. The shuttle is rotated about its central axis during one cycle of the reciprocal movement thereof to eliminate a twist or torsion on the filament imparted by the shuttle reciprocally passing alternately over and under the mandrel wire. |
