ABSTRACT:
A slide fastener including fastener elements formed from continuous filaments of plastic material and carried by cords along inner edges of a pair of tapes, a slider having channels extending therethrough with diverging throats adjacent a diamond post in the slider, and a pair of stop members secured to the pair of tapes at the inner edges, each of the stop members engaging end abutments of the slider to limit movement of the slider and having legs extending obliquely to the inner edges of the tapes such that the legs are received in the throats of the slider when the slider is moved to close the slide fastener to prevent splay of the tapes. The cords have portions of reduced cross section between the stop members and terminal elements of the fastener elements and the slider can be assembled to receive the fastener elements after forming of the stop members by disposing the slider to receive the cord portions of reduced cross section and moving the slider along the cords away from the stop members.
