ABSTRACT:
An apparatus for manufacturing slide fasteners of a predetermined length from a continuous slide fastener chain comprising a gripper unit for gripping a leading end of the continuous slide fastener chain and feeding the slide fastener chain longitudinally along a feed path, a cutter unit for cutting the slide fastener chain into a succession of slide fasteners of a predetermined length, and a plurality of slider holding units disposed downstream of the cutter unit along the feed path. The slider holding units are movable between a first position to hold a corresponding number of sliders in the feed path of the slide fastener chain to thread the sliders onto the slide fastener chain from the leading end thereof as the slide fastener chain is fed downstream by the gripper unit, and a second position remote from the first position. Each of the slider holding units is operative independent of the operation of another slider holding unit so that one or more sliders can selectively be threaded on the slide fastener chain by holding a desired number of the slide holding units in the first position.
