ABSTRACT:
In a separable slide fastener, a succession of discrete fastener elements molded on a pair of parallel connecting yarns at regular distances are folded individually in a U-shape about an inner edge of each of opposed fastener tapes and are attached by sewing threads. Several of the fastener elements are removed from a bottom end portion of each fastener tape by cutting the connecting yarns with corresponding part of the sewing threads remaining uncut as cores. Each of upper and lower legs of a lowermost one of said fastener elements is flatted to form a small-thickness portion. An insertion pin of a separable bottom stop assembly is attached to the bottom end portion of one fastener tape by clenching so as to hold the small-thickness portions and the cores, and a box pin is attached to the bottom end portion of the other fastener tape in the same manner.
