发明名称 Method of Molding a Separable Bottom Stop Assembly on a Concealed Slide Fastener
摘要 A method of molding a separable bottom stop assembly on a concealed slide fastener, comprising: forming a number of space portions (6) devoid of fastener elements (4) at predetermined intervals in a concealed slide fastener chain (1); impregnating molten synthetic resin in fastener tapes (7) at areas around the space portion (6); heat-molding and hardening the tapes (7) in such a manner that confronting edge portions of the tapes (7) are turned over; cutting the tapes (7) across the space portion (6); injection molding a second pin member (14) of the separable bottom stop assembly (3) on the edge portion of one tape (7) and a first pin member (22) of a box member (19) on the edge portion of the other tape at the space portion (6), contiguously to the fastener elements (4); and attaching a box (22) to the first pin member (22) to complete the box member (19). The result is that a separable concealed slide fastener, which could not be put to practical use conventionally, can be manufactured simply. <IMAGE>
