ABSTRACT:
For use in a papermaking machine or paper converting mechanism having an arrangement for winding a roll of paper onto a core at high speed, an expanding core chuck for insertion into a roll core which includes a spindle mounted for rotation within a housing, a cone mounted on the spindle and having camming surfaces thereon, a piston reciprocable axially of the spindle, means for introducing hydrostatic pressure to one end of the piston, a cup secured to the opposite end of the piston and having a plurality of radially deflectable leaves in spaced relation therearound. The leaves have angular surfaces thereon engageable by the camming surfaces on the core. When the angular surfaces are contacted by the camming surfaces of the core due to movement of the piston, the leaves are deflected outwardly into tight fitting relationship within the interior of the roll core.
