Abstract:

A device for mounting a roll of material that includes a fiber core around which the material is placed. The device includes a lightweight, polymeric collett that is inserted into the fiber core. The polymeric collett has a plurality of individual segments that expand radially with respect to a central axis of the roll of material. Each of the plurality of individual segments includes an inner wall and an outer wall. The inner walls of the plurality of individual segments define a cavity. The outer walls engage an interior surface of the fiber core. An arbor engages the inner walls of the plurality of individual segments and forces them outwardly to place the outer walls into tight, frictional engagement with the interior surface of the fiber core.
