Abstract
A chuck assembly for insertion into the core of a paper windup roll to assure uniform winding and unwinding. The chuck assembly includes a shaft which has an axis coinciding with the desired axis of rotation of the core and bearing means which support the shaft for rotation therein. At the end of the shaft there is a stub shaft of reduced diameter which is received within a chuck having an axial bore therein. The bore is sufficiently larger in diameter than the diameter of the stub shaft to permit limited relative movement. The chuck further has a tapered wedge at its forward end which is arranged to fit tightly within the core and resilient spring means are provided to accommodate the relative movement between the stub shaft and the larger diameter bore in which it is located.
