Abstract: An apparatus for holding sliders for application to slide fastener stringers comprises an indexing plate for intermittently advancing sliders through consecutive angularly spaced positions, a chute, guide groove, and pusher rod for supplying a slider to the indexing plate at a first position, a presser member coacting with the indexing plate to lock the slider at a succeeding second position, and a pivotable lever for removing the slider from the indexing plate at a succeeding third position. The indexing plate includes a plurality of angularly spaced slider supports each for receiving one slider at a time and intermittently drivable by a rack-and-pinion mechanism powered by a fluid-pressure actuator.

Abstract: An apparatus for supplying slide fastener sliders comprises a track for carrying thereon the sliders stacked sideways with their respective pull tabs arranged in the recumbent position for gravity delivery of the sliders to a groove in a base. A slider retainer is engageable with the recumbent pull tab of the leading slider for retaining the same with the slider body position so as to release the same from engagement with the slider retainer, and substantially at the same time to allow the leading slider to fall in the groove. A feeding device feeds the slider in and along the groove to a predetermined position. The apparatus further comprises an arrangement for correcting the posture of the slider to have the pull tab raised substantially perpendicularly to the slider body wings.

Abstract: A slide slidably mounted on an arm secured to an indexing plate has a slider seat for supporting thereon a slider body with its pull tab inserted in a slot defined between the slide and the arm. The slider pull tab is immovably held in the slot by a ball mounted in the arm and spring-biased into an aperture in the pull tab. Upon holding of the pull tab, the slide is slightly moved under the resiliency of a spring to lift the slider body until a locking pawl to which the pull tab is connected is withdrawn out of a slider guide channel. A block mounted on a fixed frame contains a spring-biased presser which, upon lateral alignment with the spring-biased ball, forces the ball into locking engagement with the pull tab in the slot, thereby locking the slider for application to a pair of slide fastener stringers.

Abstract: A presser foot for a concealed slide fastener has a sole plate slidably supported on a stem, the sole plate having in its sole a pair of guide grooves extending along the length thereof. A first needle hole in the sole plate is located between the guide grooves and a second needle hole therein is located at one side of the sole plate. The sole is divided by the guide grooves into two portions, one of which is wider than the other, the second needle hole being provided in the wider sole portion. A throat plate of a sewing machine has a third needle hole and a pair of spaced slots one on each side of the third needle hole, the slots receiving a pair of feed dogs, respectively.
