Abstract
A fastening machine (e.g. for rivets) has a fastening head where the fasteners are brought into alignment with the punch and die in a carrier tape. The carrier tape has a web with slits or teeth engageable by a sprocket wheel which sequentially advances the fasteners until the stems engage a retractable stop. When the punch is advanced, the fasteners are pushed through the carrier tape to be deformed by an upsetting die aligned with the punch. In modified embodiments, the fasteners are urged transversely from the web of the carrier tape, the carrier tape being advanced by a gear which engages teeth on a side flange on the carrier tape. The sprocket wheel may be remotely driven e.g. by a flexible cable drive to accommodate the movement as the fastening head is advanced towards, or retracted from, the upsetting die.
