<p>A method of forming end stops (9) to a continuous slide fastener chain (C) including element-free space portions (10) at longitudinally spaced intervals, wherein as the chain (C) is fed in the backward direction, a pair of rows of interengaged coupling elements (E) extending on the downstream side of an element-free space portion (10) is spread open by a chain splitting apparatus (6) for subsequent molding of a separable end stop (9a, 9b) whereas a pair of rows of coupling elements (E) on the upstream side of the element-free space portion (10) is kept in engaged condition. After the separable end stop (9a, 9b) is molded, the chain (C) is fed in the forward direction during which time a sprue portion (9c) and gate portions (9d) formed integrally with the separable end stop (9a, 9b) are caught by a chain splitting member (6a) of the chain splitting apparatus (6). The chain splitting member (6a) is then lowered to automatically remove the sprue portion (9c) and gate portions (9d) from the separable end stop (9a, 9b). <IMAGE></p> |
