A core chuck is disclosed which employs a set of expandable jaw sections. The jaw sections are expandable by operation of an adjusting pinion to which the jaw sections are connected by means of a keyway element. The chuck may be attached to a shaft or bearing stand by means of an adaptor plate.

Core chuck

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.
