ABSTRACT OF THE DISCLOSURE A pair of continuous fastener stringers are fed intermittenly for a distance corresponding to an indivi- dual slide fastener length. A strip is placed on one surface of the stringers while the latter are held sta- tionary between intermittent movements. Then, beat 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 which 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 out 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.
