ABSTRACT:
A core for core wound paper products. The core is made by wrapping dual plies in a spiral pattern and adhering the plies together. The edge of one ply overlaps the ply gap of the other ply, preventing a single ply thickness from occurring anywhere on the core. Alternatively, the edge of each ply may overlap the ply gap of that respective ply. In yet another embodiment, the overlap may be formed by a separate ply applied to either ply.
