Abstract: In an apparatus for manufacturing a bidirectionally openable slide fastener, a guide unit is disposed between a pair of spaced first and second slider attachment units for holding taut an individual slide fastener length between the guide unit and a chain gripper even when the individual slide fastener length is severed from a slide fastener chain after the threading of a first slider on the first slider attachment unit but before the threading of a second slider on the second slider attachment unit. With this guide unit, the individual slide fastener length is tensioned properly, so that the second slider can be smoothly and reliably threaded over the slide fastener length.

Abstract: An apparatus for threading a slider onto a pair of stringers of a slide fastener comprises a slider holder disposed in a longitudinal path of the opposed stringers, an aligning member disposed downstream of the slider holder for laterally aligning respective leading ends of the opposed stringers with each other which stringers have been threaded through the slider, and a clamp disposed between the slider holder and the aligning member for holding the opposed stringers in their aligned position. The clamp and the slider holder are relatively movable away from each other along the longitudinal path to draw the opposed stringers from the slider until endmost fastener elements are coupled.

Abstract: An apparatus for holding a slider includes a holder body defining a space for receiving a pull tab, and a slider support having a first seat and a bore below the first seat. A locking lever is pivotally disposed in the space and has a locking projection. A supporting arm is angularly movable between an inclined position in which its second seat is positioned remotely from the first seat and it presses the locking lever so that the projection is retracted into the bore, and an upright position in which the second seat is positioned adjacent to the first seat. As the arm is angularly moved from the inclined position to the upright position, the locking lever is allowed to turn so that the projection projects through the bore for engagement with the slider's pull tab.

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.

The auxiliary slider support is reversible in position relatively to the one slider holder in such a manner that the distance between the one slider support and the auxiliary support varies upon reversal of the auxiliary slider support.

Abstract: A slider applicator has a stopper attached to an end of a slide rod slidably mounted in a pivotable casing for movement parallel to a feed path along which a slide fastener chain is fed through a slider supported on a slider holder. When the stopper is displaced for a prescribed distance by box and insertion pins on the slide fastener chain, a microswitch is actuated to operate an air cylinder for angularly moving the casing to lift the casing out of engagement with the box and insertion pins, which are now allowed to move with the slide fastener chain past the stopper. In the event of improper positioning of one of the box and insertion pins, adjacent endmost coupling elements are jammed in a slider to thereby prevent the stopper from being displaced for the prescribed distance. A sensor switch is then actuated to signal such improper positioning of one of the box and insertion pins.
