ABSTRACT:
An expanding mandrel chuck for internally gripping a tubular core. The chuck has a cylindrical sleeve which can be slid over the shaft of a web handling apparatus, core cutter, or other apparatus. A plurality of hexagonal shaped cams surround the intermediate portion of the sleeve. The flat surfaces of these cams are aligned. A plurality of circumferentially spaced, generally pie-shaped jaw segments are freely positioned in overlying relationship with respect to the cams. Each segment has a flat inner surface overlying a corresponding set of faces of the cams. Guide pins extend from opposing end surfaces of each segment and slide within radial slots in disks mounted on the sleeve on opposite sides of the segments. Spring rings are mounted in grooves between the cams and yielding urge the jaw segments radially outwardly. Relative rotation between the cams and the segments causes the cams to push the segments radially outwardly into positive gripping relationship with the inner wall of a surrounding core.
