Abstract: In a bottom stop assembly for a separable slide fastener, an open box has a first channel for receiving a box pin firmly attached on an end of a stringer. The open box has front and rear walls between which a web intervenes at their intermediate portions. Right and left flanges define with the web and the front and rear walls the first and a second channel for receiving an the box pin and an insert pin firmly attached on the lower ends of the other stringer. The channel on the box pin insertion side has projections on the flanges extending inwardly, the projections urging the box pin against the web. Upper and lower engaging surfaces formed by a cut-out embrace the web from up and down to limit axial movement of the box pin in the open box. A bulge on the lower end of the box pin bears against the flanges presses the projections to urge the box pin against the web. With these arrangements, any movement of the box pin inside the box is completely restricted.

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.
