A pair of continuous slide fastener stringers having a pair of stringers tapes including thermoplastic synthetic fibers and a pair of integrated rows of fastener elements mounted on the confronting edges of the stringer tapes are provided with an element-free gap therein and are cut off transversely of the element-free gap to produce an individual slide fastener length with ultrasonic processing means. Simultaneously, the cut edges and ends are fused, and top and bottom end stops are mounted respectively on the fastener slide stringers and the slide fastener length with heat induced by the ultrasonic processing means. The interengaged element rows while advancing are introduced into a slider through its mouth which is supported on a slider holder, with portions of the top end stop being forcibly flexed away from each other by the body of the slider, thereby allowing the top end stop to move past the slider. |
