ABSTRACT OF THE DISCLOSURE An apparatus for manufacturing woven slide fastener stringers comprises means for shedding a plurality of warp threads, a coiling mechanism for coiling a monofilament of synthetic resin around a mandrel in a conical orbit to form a series of coiled coupling elements and a weft inserter reciprocable across the warp shed and the conical orbit for inserting a weft thread into the warp shed, by which the coiled coupling elements can be woven into a stringer tape along a longitudinal edge thereof as the tape is woven of the warp and weft threads. The weft inserter includes an arm which, when the weft thread is inserted, is engageable with the monofilament to displace the latter out of the path of insertion of the weft thread so that the weft thread can be inserted smoothly without being frictionally engaged by the monofilament.
