ABSTRACT:
A pair of separable slide fastener stringers is fed in one plane along parallel spaced paths, respectively, toward throats of a Y-shaped guide channel in a slider fixed in position. Pins of the stringers are introduced into the guide channel through the throats, respectively, in the slider while keeping the separable slide fastener stringers in the parallel spaced paths. The separable slide fastener stringers are inserted through the slider with the pins guided by guide flanges, respectively, and a diamond of the slider while moving the separable slide fastener stringers in the one plane along the parallel spaced paths and at the same time allowing the stringer tapes to flex.
