2123990 9309918 PCTABS00022 A fastening machine (e.g. for rivets) has a fastening head (20) where the fasteners (30) are brought into alignment with the punch (22) and die in a carrier tape (10). The carrier tape (10) has a web (11) with slots (15, 16) or teeth engageable by a sprocket wheel (27) which sequentially advances the fasteners (30) until the stems (31) engage a retractable stop (32). When the punch (22) is advanced, the fasteners (30) are pushed through the carrier tape (10) to be deformed by an upsetting die aligned with the punch (22). In modified embodiments, the fasteners (30) 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 (27) may be remotely driven e.g. by a flexible cable drive to accommodate the movement as the fastening head (20) is advanced towards, or retracted from, the upsetting die.
