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.
