Abstract
A method and apparatus for the manufacture of slide fastener carrying a discrete formation of differently colored elements in selected orders. Method and apparatus are disclosed for feeding a plurality of colored elements selectively one at a time in a vertical direction and transferring one such element horizontally to a predetermined position for gravity fall onto a stringer tape.
Claims6
In the manufacture of a slide fastener carrying a discrete formation of a plurality of groups of colored coupling elements in selected orders and at predetermined intervals along a longitudinal edge of a stringer tape, a method which comprises the steps of receiving and feeding a plurality of differently colored coupling elements selectively one at a time from respective vertically disposed chutes, transferring said one coupling element horizontally to a predetermined position for gravity fall onto the longitudinal edge of the tape and clamping said one element in place, followed by receiving and feeding a next selected one of said colored elements from the corresponding one of said chutes.
An apparatus for the manufacture of slide fasteners having a plurality of groups of differently colored coupling elements in selected orders and at predetermined intervals along a longitudinal edge of a stringer tape, the apparatus comprising a plurality of vertically disposed chutes for feeding respective groups of colored coupling elements, a horizontally disposed base, a slide supported on said base for horizontal reciprocating movement and having a pocket selectively registrable with one of said chutes, a transfer chute integral with said base and having an opening registrable with said pocket for transferring said coupling elements one at a time onto the tape edge, a controlled drive means comprising cam members and a cam follower and adapted to effect horizontal reciprocating movement of said slide, and a program-control drive device adapted to drive said cam members selectively.
