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 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.
Claims10
A reusable collapsible core for winding sheet material thereon so that said wound core can be placed in a press having at least one mandrel with an outside radius and length, said core comprising:
- at least two arcuate sections with each section having a predetermined inside arc cross-section and a predetermined length, both of which correspond to outside radius and length the mandrel of said press;
- each arcuate section having a first and second edge along the length of said section, each of said sections further comprising an interlocking joint assembly along attached along the edges of said arcuate sections such that the first interlocking join assembly of one arcuate section may be releasably attached to the second interlocking joint assembly of an adjacent arcuate section wherein attaching said accurate sections to one another provides said reusable collapsible core and wherein releasing one said first interlocking joint assembly adjacently attached to said second interlocking joint assembly enables said reusable collapsible core to collapse such that said core can be easily removed from the sheet material wound thereon.
