    Patent number: 4079896
    Abstract: An expandable chuck is attached to a rotating mandrel by means of a locking ring. The chuck includes arbor and shoe segments in camming relationship whereby relative movement is effective for increasing the effective diameter of the shoe segments. A core upon which a web material is to be wound is placed over the shoe segments which are then extended by rotation of an adjusting nut to secure the core to the shoe segments. For high torque applications a pair of chucks may be employed.
