<p>Fastener delivery apparatus comprises first and second elongate fastener delivery tubes (22, 23, 24) in which fasteners are conveyed by compressed air. An interface housing (20) comprising receives the respective ends of the delivery tubes in axially aligned apertures (25a, 28). The first and second delivery tubes are supported in the apertures with their ends spaced apart such that there is a predetermined clearance (42) between the end peripheral wall of the first delivery tube and the end of the peripheral wall of the second delivery tube. The interface may be a shuttle for moving an incoming delivery tube (24) selectively into alignment with one of several outlet tubes (22, 23). Alternatively it may be a docking station where two parts of the housing are brought into and out of register.</p> |
