A material layering device may include a first pinning roller and a second pinning roller. A distance between the first pinning roller and the second pinning roller is less than a diameter of a substrate. The device also includes a return system, wherein the return system comprises a plurality of rollers. The device also includes a belt, which may have a first loop portion disposed between and protruding beyond the first pinning roller and the second pinning roller. The first loop portion also wraps about an intended substrate along an arc greater than about 180 degrees. The device further includes a feed portion coupled to the first loop and extending outwardly from the second pinning roller opposite the first loop and providing a surface upon which a sheet can be placed. Furthermore, the device also includes an adjustment mechanism coupled to one of the rollers.
