ABSTRACT:
An elongate continuous slide fastener chain is fed in alternately opposite longitudinal directions in various steps (a) through (e). First, reinforcing film members are attached to the chain across an element-free space, and then a hole is defined in the chain across the element-free space. Thereafter, an insertable pin, a box pin, and a box are attached to the chain through the hole, and then a slider is mounted on a pair of rows of coupling elements through the element-free space. Finally, top end stops are fixed to beaded edges of the chain, which is then cut off transversely thereacross into a separable slide fastener.
