Abstract

A core end protector comprised of a shock absorber and an annular, rigid attachment section that is attached to each end of a cardboard tissue core is provided. The core end protectors are securely mounted on the ends of the core. The outer diameter of the core end protector matches the outer diameter of the core. The inner diameter matches the inner diameter of the core. The core end protectors are made both with a rigid base section that mates to the core end face and a softer, shock absorbing section that comes in contact with external forces and impact loads. One single material or a plurality of materials may be used.

Claims (9)

1. A winding core end protector, comprising:

an annular, rigid base section mated directly to an end of a winding core;

an annular, shock absorbing section fixedly attached to said rigid base section;

wherein the winding core end protector has an external diameter generally equal to a winding core external diameter, and an internal diameter generally equal to a winding core internal diameter;

wherein the rigid base section is made from a material from the group consisting of metals or high durometer rigid polymers; and

wherein the end protector shock absorbing section is made from the group consisting of softer durometer polymers or elastomeric materials, said materials characterized by surface toughness, overall flexibility upon impact, and high resistance to material creep and compression set under load;

wherein the rigid base section has a plurality of holes formed therein, each said hole adapted to receive a fastener to hold the rigid base section directly to the winding core end;

wherein the shock absorbing section has a plurality of cavities to allow said fasteners to pass through and engage the rigid base section with the winding core end;

wherein the shock absorbing section is comprised of a plurality of nubs with a space between each adjacent nub; and a plurality of holes formed between the nubs.
