ABSTRACT:
Apparatus for automatically installing blind rivets includes structure for automatically feeding new rivets one at a time to the front of the rivet installation head. Each rivet is supported in the appropriate position by a pair of support fingers (36,36) whilst the installation head (19) advances towards the rivet. The rivet feeding structure is provided with rivet guiding fingers (51,51) which guide the rivet stem (41) into the approaching anvil aperture (48) in the installation head. As the installation head continues to advance, it pushes out of the way first the guiding fingers (51,51) and then the support fingers (36,36) so that the rivet can reach the workpiece and be installed in it.
