ABSTRACT:
As a pair of fastener tapes is supplied through a molding machine and then through a fiber hardening agent applying and impregnating unit, a predetermined length of coupling element rows are molded on and along confronting beaded edges of the fastener tapes, and simultaneously a separable bottom stop assembly composed of a pin member and a box member and top stops are molded about one ends and the other ends of the coupling element rows, whereupon a fiber hardening agent is applied over and impregnated in the tape surfaces of the prospective bottom end portions by the fiber hardening agent applying and impregnating unit.
