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.
Claims18
A core member for storing shrink film, the core member comprising a plurality of rollers, wherein each roller of the plurality of rollers comprises a disc and a core extending upwardly from the disc, wherein the plurality of rollers are concentrically aligned such that the core of each roller is longitudinally aligned along an axis and the disc of each roller is laterally aligned along a plane, wherein at least one roller comprises an annular flange extending upwardly from the disc outward of the core to define an inner disc between the core and the annular flange.
A core member for storing shrink film, the core member comprising:
- (a) an inner roller comprising a first core and a first outer disc extending outwardly from a bottom portion of the first core;
- (b) an intermediate roller comprising a second core, a first inner disc extending outwardly from a bottom portion of the second core, a first annular flange extending upwardly from the first inner disc, and a second outer disc extending outwardly from a bottom portion of the first annular flange;
- and
- (c) an outer roller comprising a third core, a second inner disc extending outwardly from a bottom portion of the third core, a second annular flange extending upwardly from the second inner disc, and a third outer disc extending outwardly from a bottom portion of the second annular flange;
- wherein the inner roller, the intermediate roller, and the outer roller are concentrically aligned along a longitudinal axis;
- wherein the third core of the outer roller is insertable within the second core of the intermediate roller such that the second outer disc of the intermediate roller is positioned adjacent to the second inner disc of the outer roller within the second annular flange;
- wherein the second core of the intermediate roller is insertable within the first core of the inner roller such that the first outer disc of the inner roller is positioned adjacent to the first inner disc of the intermediate roller within the first annular flange.
A method of winding film onto a core member comprising the steps of:
- (a) assembling an outer roller of the core member within an inner roller of the core member such that the outer roller and inner roller are concentrically aligned along a longitudinal axis and laterally aligned along a plane, wherein the outer roller comprises an annular flange defining a recess, wherein film is inserted through the recess of the annular flange to the inner roller;
- (b) rotating the inner roller to wind film about a core of the inner roller;
- and
- (c) rotating the outer roller to continuously wind film from the inner roller about a core of the outer roller.
