ABSTRACT:
An apparatus for feeding and transferring discrete coupling elements successively one at a time for attachment onto a stringer tape comprises a feed unit including a vertically disposed feed chute and a transfer unit including first and second slides both supported on a base for horizontal movement effected by a cam. The thickness of the first slide is substantially equal to the height of the leg portions of the element. A pocket is formed in the junction of the first and second slides for receiving an element from the chute and communicates with a slit in the base which provides a suction air for facilitating the fall by gravity of a leading element apart from an ensuing element. The base includes a transfer chute for receiving one element from the pocket and transferring same onto the tape.
