ABSTRACT:
An apparatus for manufacturing a slide fastener stringer having a woven stringer tape and a coiled coupling element woven therein, includes a needle loom for weaving the stringer tape of warp and weft threads, a mandrel for extending at an angle to the warp threads, and a coiling rotor assembly to be located alongside of the warp threads for winding a monofilament around the mandrel in a circular path to form the coiled coupling element, which is then woven into the stringer tape by the weft thread. A monofilament guide means is fixed with respect to the coiling rotor assembly and is located in substantially, three-dimensional point-symmetry relation to a distal end portion of the mandrel with respect to the center of the circular path, so that the monofilament is kept under substantially uniform tension while being rotated by the coiling rotor assembly.
