CORE FOR CORE WOUND PAPER PRODUCTS HAVING PREFERRED SEAM CONSTRUCTION

摘要

A core for core wound paper products. The core is made by wrapping dual plies (22, 24) in a spiral pattern and adhering the plies together. The edge (34) of one ply (24) overlaps the ply gap (36) of the other ply (22), preventing a single ply thickness from occurring anywhere on the core. Alternatively, the edge (34) of each ply may overlap the ply of that respective ply. In yet another embodiment, the overlap (42) may be formed by a separate ply applied to either ply.
