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.
