ABSTRACT:
In order to ensure a firm bond between a row of coupling elements of a slide-fastener half and a stringer tape provided at a longitudinal edge with a carrier cord around which these elements are molded, the cord is compressed during the molding operation between jaws of two mold halves imparting to the engaged cord portion a generally triangular cross-section with rounded corners, the base of the triangle adjoining the stringer tape to define a pair of transverse shoulders embraced with positive fit by complementary tail sections of the coupling elements.
