ABSTRACT:
A slide-fastener closing apparatus, for moving opposed stringers relative to a slider, includes upper and lower feed rollers coactive to move the stringers in either direction along a feed path, and an arrester normally urged to project into the feed path. After the stringers with the slider are supplied forwardly past the arrester, the two rollers are driven to move the stringers rearwardly so that the slider is caught by the arrester until the slide fastener is fully closed. Then the rollers are reversely driven to move the closed slide fastener forwardly for discharging.
