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.

First claim

I claim:

1. 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.

2. The core member assembly of claim 1 , wherein the intermediate roller comprises a second core extending downwardly from a central portion of the first inner disc, wherein the outer roller comprises a third core extending downwardly from a central portion of the second inner disc.

3. The core member assembly of claim 2 , wherein the first core is positioned on the second core, wherein the second core is positioned on the third core.

4. The core member assembly of claim 1 , wherein an inner surface of the first opening, the second opening, and the third opening each comprise at least one channel extending within a bottom portion of the inner surface.

5. The core member assembly of claim 4 , wherein the inner surface of the first opening, the second opening, and the third opening each comprise three channels spaced equidistantly about the inner surface.

6. The core member assembly of claim 5 , wherein the channels of the third opening are offset relative to the second opening, wherein the channels of the second opening are offset relative to the channels of the first opening.

7. The core member assembly of claim 1 , wherein a bottom surface of the first outer disc comprises at least one notch extending within the first outer disc.

8. The core member assembly of claim 7 , wherein the second and third outer discs comprise at least one opening longitudinally aligned with the at least one notch of the first outer disc.

9. The core member assembly of claim 1 , wherein a top surface of the first inner disc is lower than a top surface of the second outer disc, wherein the top surface of the first inner disc is configured to receive a bottom surface of the first outer disc.

10. The core member assembly of claim 1 , wherein a top surface of the second inner disc is lower than a top surface of the third outer disc, wherein the top surface of the second inner disc is configured to receive a bottom surface of the first inner disc.

11. The core member assembly of claim 1 , wherein the outer roller comprises an intermediate disc positioned between the second inner disc and the third outer disc, wherein a top surface of the intermediate disc is lower than a top surface of the third outer disc, wherein the top surface of the intermediate disc is configured to receive a bottom surface of the second outer disc.

12. The core member assembly of claim 1 , wherein the outer roller comprises a flange positioned between the second inner disc and the core, wherein a top surface of the flange is lower than a top surface of the second inner disc, wherein the top surface of the flange is configured to receive a bottom surface of a second core of the intermediate roller extending downwardly from a central portion of the first inner disc.

13. The core member assembly of claim 1 , wherein the outer roller comprises a third annular flange positioned about a circumference of the third outer disc, wherein the third annular flange extends downward from the third outer disc.

14. The core member assembly of claim 1 , wherein the first annular flange comprises a first recess extending through the first annular flange, wherein the second annular flange comprises a second recess extending through the second annular flange, wherein the second recess is laterally aligned with the first recess.

15. 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.

16. 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.

17. The method of claim 16 , wherein the first roller is in a raised position relative to the second roller when the first roller is wound with the film.

18. The method of claim 16 , wherein the second roller is raised relative to the first roller to position the second roller about the first roller when the second roller is wound with the film.

19. The method of claim 16 , wherein the first and second rollers each comprise an opening extending through a central portion of the first and second rollers, wherein the first and second rollers are positioned on a winding device such that a cylinder of the winding device is inserted through the openings of the first and second rollers.

20. The method of claim 16 , further comprising positioning a third roller about the second roller to align a third outer disc of the third roller laterally along a plane of the second outer disc and a second annular flange of the third roller outward of the second outer disc, and continuously winding film about the third roller by rotating the first, second, and third rollers simultaneously to wind the film about the second annular flange on a top s
