ABSTRACT:
In a fastener-attaching apparatus equipped with a feeder for selectively delivering two different component pieces of fasteners from two separate feed hoppers to an attaching point, the improvement in the feeder which comprises a pair of tracks having a pair of vertically parallel fastener-guiding T-grooves which extend from the delivery openings of the two feed hoppers and terminate in vertically juxtaposed fastener discharge outlets, a shifting mechanism for selectively closing and opening the T-grooves of the tracks, a guide having a guide groove provided at right angles to the T-grooves and extending to the fastener-attaching point, with the fastener discharge outlets open in the guide groove, a fastener limiter slide located opposite to the discharge outlets and urged by a spring slidably and partly into the guide groove, the limiter slide having separate fastener-piece-receiving recesses corresponding, respectively, to the upper and lower discharge outlets, and a pusher bar slidable in the guide groove and which, when driven through the guide, causes the limiter slide to retract and pushes each fastener piece to the attaching point.
