Abstract: 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.

Abstract: An apparatus for attaching a pair of fastener elements of a garment fastener to a garment fabric, comprises an optical indicator for designating a position of the garment fabric where the two fastener elements are to be attached. The indicator includes a light projector having a light source for projecting a beam of light, a reflector for reflecting the light beam downwardly, and means defining an aperture for the passage therethrough of the reflected light beam. An actuator is operatively connected to the light projector for reciprocating the same toward and away from a position where the aperture is in registry with a common vertical axis of the two fastener elements. The indicator is structurally and functionally separated from a pusher mechanism for supplying one fastener element to an upper unit of the apparatus.
