Abstract: A chuck is mounted on a drive shaft and torque can be transferred to an inner ring (30) of the chuck from the drive shaft. A casing (28) of the chuck surrounds the inner ring and supports four circumferentially-spaced cam elements (40) for gripping and supporting the core. Each cam element comprises a cam pivotably mounted on the housing and operated by a cam roller (58) mounted on the inner ring. Relative rotation of the inner ring and the casing causes the cam roller to move along a cam surface on the underside of its cam and to raise either end of the cam to engage the core. A switching element (80) is housed in a chamber in the casing between each pair of cam elements. Each switching element comprises a detent spring (90) having a central detent and being captive within the chamber (82), and a detent roller (88) mounted on the inner ring.

Abstract: A core chuck has a generally spool-shaped mandrel with an outer surface configured to define three longitudinally extending lobes. A set of three or more arcuate friction plates surround the lobular outer surface of the mandrel and are movably held in place with elastic bands. Each friction plate has an inner surface contoured to conform to the shape of a corresponding lobe of the mandrel and an outer surface for frictionally engaging the inside surface of a core. The outer surfaces of the friction plates align to form a cylindrical shell. The friction plates are circumferentially slidable around the mandrel between first or retracted positions wherein the plates rest on their respective lobes and form a shell of a first diameter and second or expanded positions wherein the friction plates span adjacent lobes and form a shell of a second diameter greater than the first diameter.

The two support-removing members are respectively supported on the two side portions of the shaft main body in such a manner that they can be freely rotated about their respective support shafts. A tension-coiled spring is bridgingly disposed between the two support-removing members, so that the two support-removing members remain in standing positions when no external force is applied to them.

Abstract: A material transfer system is disclosed using a hollow cylindrical lock shaft for rewinding flexible material from an original core to at least one transfer core. The shaft has an interior and exterior wall, a length, and at least one curved locking base recessed along the length. The bases have a first and second wall with a floor having a progressively decreasing radius from the first to the second wall. Multiple legs extend radially inwardly from the interior wall and have gripping feet are at their distal ends. A plurality of locking ribs extend the length of the locking bases and are affixed to the floor at the each end of the rib. The locking ribs have a diameter sufficient to enable the locking rib outer circumference to extend beyond the circumference of the shaft exterior. At least one locking strip is affixed to at least a portion of the shaft's length, extending beyond the circumference of the exterior wall to prevent the cores from moving freely.
