APPARATUS FOR CLOSING SLIDE FASTENER COUPLING ELEMENT CHAINS

摘要

An apparatus for closing a succession of partly disengaged slide fastener coupling element chains with sliders mounted respectively thereon includes an element-engaging block assembly having a guide channel for constrictingly receiving a disengaged portion of each coupling element chain to close the same. The assembly includes a movable element-engaging block reciprocably movable toward and away from a stationary element-engaging block to selectively define therebetween the guide channel in timed relation to detection by a sensor of an element-free space between the successive chains and the slider.
