Abstract:
Apparatus for holding a plurality of cylindrical cores while strip material such as tape is simultaneously wound thereon. The device includes a mandrel of generally overall cylindrical shape in which at least a pair of slat segments are adapted to move radially outwardly and inwardly with respect to the mandrel. Each slat additionally includes a plurality of laterally circumferentially extending longitudinally spaced grooves in which the cores are positioned and a groove base wall having an opening through which a pressure member is adapted to extend so as to apply a local pressure to the interior portions of the cores. When the slats are radially expanded as by the application of fluid pressure to a bladder, frictional holding force is applied to the cores so as to better control the winding tension of the tape strips being wound thereon.
