Abstract
Air pressure means for maintaining rivets in axial alignment as they pass through a feed tube to a riveting machine. The air pressure means comprises a circumferentially spaced series of air discharge passages directed obliquely toward the axis of the feed tube and in the direction of travel of the rivets whereby a conical pattern of air pressure is directed against the shanks of the rivets to urge them into axial alignment in the feed tube.
