Abstract
A fastener delivery tube (1) is connected between a supply of fasteners, such as rivets (2), and the nose of a fastener setting machine. The delivery tube (1) is connected to an outlet tube (7) of a source of compressed air (3), the outlet tube (7) having an internal bore substantially equal in size to the internal bore of the delivery tube (1). The supply of fasteners is connected to the delivery tube via a feeder tube (9) and transfer gate (4). The transfer gate (4) is sealed so as to prevent leakage of air from the delivery tube (1). The arrangement reduces turbulence in the delivery tube (1) ensures that friction between the fastener (2) and the tube (1) is reduced and permits compressed air to be supplied at significantly lower pressure than has heretofore been possible.
