ABSTRACT:
A reusable core that is suitable for having paper or other sheet material wound thereon. A multi-sectioned core is provided that is easily assembled. Interlocking sections that provide a pivot are held together by a sliding rod assembly inserted therein. One of type of rod assembly is preferable held into position by use of a snap ring or other similar fastening arrangement. A second type of rod assembly is a quick release design that can be easily pulled free by an integral handle. By removing the quick release rod, a key arcuate section is able to pivot thus causing the enabling the other two sections to likewise pivot inwardly, collapsing the core thereby permitting easy removal of the core from any remaining sheet material that must be discarded. The sheet material is held onto the core by means of a strip of double sided tape until the core is wound several times to keep the sheet material firmly in place.
