ABSTRACT:
An apparatus which acquires individual articles having a substantially cylindrical aperture therein from a supply of roughly aligned articles in a storage bin. The apparatus grips the article on the interior wall of the cylindrical aperture therein. The gripper is moved to retract the article from the storage bin. The article is then moved to a receiving member which aligns the longitudinal axis of the cylindrical aperture of the article substantially parallel or coincidental with the longitudinal axis of the receiving member.
