ABSTRACT:
A pair of continuous fastener stringers are fed intermittently for a distance corresponding to an individual slide fastener length. A strip is placed on one surface of the stringers while the latter are held stationary between intermittent movements. Then, heat and pressure is applied to the stringers at its portion where the strip has been placed upon; to fuse adjacent coupling elements with each other and with a pair of stringer tapes, and the latter with the strip, and to shape the fused coupling elements into a desired configuration. Such shaped coupling elements are cut to provide a separable pin and a retainer pin. Simultaneously with this cutting, the stringers are cut along a line extending transversely of the stringers and passing near the two pins to provide an individual slide fastener length. A retainer is attached to the retainer pin.
