Abstract
Apparatus for presenting blind rivets (11) of the type comprising a shell (12) and a projecting stem (13), one at a time for pick-up by the nosepiece (28) of a rivet setting tool, includes gate means comprising a pair of guide members (24) for receiving a rivet (11) blown by air along a hose (39). The guide membes are urged by a spring (25) into their closed position, in which they arrest each rivet and position it in uniform orientation with its stem (13) projecting. Locating means (30) receives the nose piece (28) and guides it into the correct position and orientation for picking up the rivet by its projecting stem. A proximity detector (37) detects when the tool nose tip is correctly located, and actuates a pneumatically driven plunger (18) which pushes the guide members (24) apart to release the rivet into the tool nosepiece (28).
