ABSTRACT:
A device for gripping the interior surface of a tube on which yarn or other material may be wrapped is provided with a hollow shaft in which is mounted an actuating member for sliding towards and away from a plug on the distal end of the shaft; a plurality of linkage arms are provided with a pair of arms being pivotally connected to each other with the remote ends of the arms respectively connected to the actuating member and the plug; the adjacent ends of the arms of each pair are pivotally connected to a pad of relatively narrow thickness so that when the actuating member moves away from the distal end of the shaft, the linkage arms will retract the pad to a position substantially within the hollow shaft.
