ABSTRACT:
Apparatus for sequentially feeding headed fasteners such as rivets includes a carrier band of resilientily stretchable material with the fasteners driven through undersize holes equally spaced along the band, the band being advanced intermittently by a reciprocating actuator, toothed for simultaneous engagement with several of the fastener heads, to bring the fasteners in sequence between a striker and the entry to a delivery conduit, the striker being reciprocated to drive each fastener brought into alignment therewith into the delivery conduit, the fastener head being forced through the stretchable band, a jet of air through the striker impelling the fastener through the delivery conduit.
