  • Patent number: 5174017
    Abstract: A pull tab loading apparatus comprising a straight inclined chute for receiving pull tabs lined up in a row, and a pull tab pushing unit for successively pushing pull tabs from a downstream end of the chute to a pull tab inlet port of a slide fastener slider assembling machine. A contact pin is rotatably supported by the pushing unit for engagement with an upper surface of the pull tab being fed from the downstream end of the chute into a guide groove of the pushing unit in an inclined posture.

  • Patent number: 4731922
    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.

  • Patent number: 4573264
    Abstract: A method and apparatus for feeding sliders to a slider pocket are disclosed. Sliders taken from the pocket are assembled on the fastening element sections of an uncut fastener chain which is moved and stopped intermittently to allow the assembly of the sliders, wherein sliders longitudinally aligned and delivered by a slider chute are fed into a slider holder one at a time. The slider holder carrying a slider received from the chute is transferred to a slider assembling station from a direction at right angles to the direction of fastener chain transfer, and the slider is loaded at the slider assembling station into the slider pocket which is provided at the upper end of a slider pocket block raised from the direction at right angles to both the fastener chain transfer direction and slider transfer direction, and the slider holder is returned to the exit of the slider chute. These steps are repeated in synchronism with the stopping of movement of the uncut fastener chain.
