Patent ID: 8221109

Claim:
A material layering device configured to attach a sheet about a removable cylindrical substrate, comprising: a first pinning roller; a second pinning roller disposed proximate the first pinning roller and oriented substantially parallel thereto, wherein a distance between the first pinning roller and the second pinning roller is less than a diameter of the removable cylindrical substrate; a return system disposed proximate the first pinning roller and the second pinning roller, wherein the return system comprises a plurality of rollers disposed about the first pinning roller and the second pinning roller; a belt configured for attaching a sheet about the removable cylindrical substrate, wherein the belt is a complete circuit, the belt comprising: a first loop portion disposed between and protruding beyond the first pinning roller and the second pinning roller, wherein the first loop portion wraps about the cylindrical substrate along an arc greater than about 180 degrees; and a feed portion coupled to the first loop and extending outwardly from the second pinning roller opposite the first loop and providing a surface for placement of a sheet that is to be attached to the removable cylindrical substrate; and an adjustment mechanism coupled to one of the first pinning roller, second pinning roller and the return system, wherein the adjustment mechanism enables release and removal of the removable cylindrical substrate from the material layering device by selectively loosening the belt.
