a method of recovering rivets from a rivet hole prior to the deformation of the rivets by the rivet dies includes the steps of positioning a suction cavity over the rivet in the rivet hole , pushing the rivet out of the hole with a rivet tail die and blocking the hole with the rivet tail die to prevent suction from the tail - side pressure nose from holding the rivet in the rivet hole . the swirling air in the suction cavity induced by the suction hose connected to the suction cavity pulls the rivet out of the hole and sucks it out of the suction cavity through the suction hose .
