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 pin inserted therein. The pin is preferable held into position by use of a snap ring or other similar fastening arrangement. By removing one pin between adjacent interlocking sections, the core collapses thereby permitting easy removal 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.
