Abstract
A core member is provided for storing shrink film. The core member includes a plurality of rollers, each having a disc and a core extending upwardly from the disc. The plurality of rollers are aligned longitudinally along an axis and laterally along a plane. The plurality of rollers are rotatable to wind the shrink film about the rollers.

A core member assembly for storing shrink film comprising:
- an inner roller comprising a first outer disc and a first core extending upwardly from a central portion of the first disc, wherein the inner roller defines a first opening extending through a central portion of the inner roller;
- an intermediate roller comprising a first inner disc and a first annular flange extending upwardly about a circumference of the first inner disc, wherein the intermediate roller comprises a second outer disc extending outwardly from a bottom portion of the first annular flange, wherein the intermediate roller defines a second opening extending through a central portion of the intermediate roller;
- and
- an outer roller comprising a second inner disc and a second annular flange extending upwardly about a circumference of the second inner disc, wherein the outer roller comprises a third outer disc extending outwardly from a bottom portion of the second annular flange, wherein the outer roller defines a third opening extending through a central portion of the outer roller;
- wherein the inner roller, the intermediate roller, and the outer roller are concentrically aligned such that the first, second, and third openings are longitudinally aligned and the first, second, and third outer discs are laterally aligned along a plane, wherein the inner, intermediate, and outer rollers are longitudinally translatable relative to each other.
A core member for storing shrink film, the core member comprising at least two rollers, wherein each roller comprises a disc for receiving film and a core defining an opening extending through a central portion of each roller, wherein the at least two rollers are concentrically aligned such that the disc of each roller is laterally aligned along a plane and the core of each roller are longitudinally aligned, wherein the opening of each roller is sized to form a continuous opening when the at least two rollers are concentrically aligned, wherein the at least two rollers are longitudinally translatable relative to each other.
A method for winding film onto a core member assembly comprising a first roller and a second roller, wherein the first roller comprises a first outer disc and a first core extending upwardly from a central portion of the first outer disc, wherein the second roller comprises a second outer disc and a first annular flange extending upwardly from an inner portion of the second outer disc, the method comprises the steps of:
- coupling an end of the film to an outer surface of the first core of the first roller;
- rotating the first roller to wind the film about the first core on a top surface of the first outer disc;
- positioning the second roller about the first roller to align the second outer disc of the second roller laterally along a plane of the first outer disc and the first annular flange outward of the first outer disc;
- and
- continuously winding film about the second roller by rotating the first and second rollers simultaneously to wind the film about the first annular flange on a top surface of the second outer disc.
