Abstract
The gripper is movable in a path transverse to the bobbin tube supports of the magazine to be aligned with a bobbin tube. The gripper employs gripping elements which engage a limited arcuate accessible portion of a bobbin tube under a force sufficient to extract the tube during movement of the gripper to a retracted position. After release from the gripping elements a transfer chute directs a bobbin tube to a receiving apparatus for subsequent delivery to a machine needing same.
