Abstract
A two piece winding core assembly is provided having a first core portion and a second core portion. The two core portions having the same construction and are positionable to combine together to form a completed cylindrical and hollow core. The two core portions having a series of locking pins and a corresponding series of receiving openings formed on opposing end faces. A series of axially elongated projections and a corresponding series of axially elongated channels are also formed on the opposing end faces of the core portions. An internal plurality of web members is formed in a structural crossing pattern on the inside surface of the core portion, with the web members providing structural rigidity to the core portions.
