An improved core for mounting on one or more core engaging elements such as a pair of chucks and a method of making an improved core are provided. The core is adapted to wind and unwind material thereon. The core may comprise a high coefficient of friction coating disposed on the inner surface of the core to improve the core-chuck interaction. The inner surface may be mechanically or chemically treated to improve core-chuck interaction.

Core with improved chuck interaction

An improved core for mounting on one or more core engaging elements such as a pair of chucks and a method of making an improved core are provided. The core is adapted to wind and unwind material thereon. The core comprises a high coefficient of friction coating disposed on the inner surface of the core to improve core-chuck interaction.

An improved support post for cushioning and supporting large products is provided. The post is made from a sheet that is convolutely wound around a mandrel and shaped into a desired shape. The improvement comprises making the sheet from multiple thicknesses of paper so that, upon winding the sheet into a tube, the middle layer of the tube is thicker than the outer layers. The post has a higher axial compression strength than a conventional post, but the same amount (weight) of material.
