Composite industrial winding core and methods

Abstract

A high performance and lightweight composite industrial winding core for winding a thin material stock thereon. In preferred embodiments, the winding core is engineered from fiber reinforced plastic and comprises a pair of elongate winding core bodies aligned along an axis having a generally cylindrical outer face with an inner face that defines the inside of the hollow cylinder. A first end wall and a second end wall enclose the ends of the winding core. A series of spaced axle supports support the winding core bodies. An inner axle face engages with an axle shaft. Portions of the winding core can be joined by an adhesive resin or bonding agent. The axle shaft can include inflatable bladders and can engage an inner tube of the winding core. A method for using a winding core to wind material stock is disclosed.
