Abstract
A tubular core assembly for a roll of paper or other sheet material has a hollow cylindrical core member of metal or plastic material, the core member having at least one lug projecting radially inwardly from an inner surface thereof adjacent to each end of the core member. Each lug is longitudinally spaced from the respective adjacent end of the core member, and an annular plastic end member is located within each opposite end portion of the core member and is a friction fit therein. Each end member has a notch at its longitudinally inner end receiving the lug adjacent to the respective end of the core member to facilitate transmission of torque and axial chuck pressure from the end members to the core member.
