Title: "FEEDERS FOR HEADED FASTENERS" ABSTRACT A feeder for headed fasteners, such as rivets (43), driven at equal intervals through a tape (44), is applicable to a riveting machine (10) and includes a plunger (25) advanced and retracted through a guide bush and with a punch (37) at its leading end. When the plunger (25) advances the punch (37) is driven through a delivery passage in the guide bush (39). A guide passage (45) leads the tape (44) to bring fasteners (43) in sequence into the delivery passage. An actuator (56), oscillatable in the guide bush (39), is moved to retracted position by the advancing plunger (25), and is automatically returned to advanced position when the plunger (25) retracts. Fastener engaging means (64) on the actuator (56) act, with each retraction and advance of the actuator (56), to engage a fastener (43) and move it towards the delivery passage from which the leading fastener (43) is driven by the advancing punch (37) which, penetrating the tape (44) holds the tape (44) against movement while the actuator (56) is moved to its retracted position.
