Abstract
A system for cutting sheet material. The system has a first roller with at least one cutting element thereon with the first roller rotatable around a first axis and the second roller having at least one receptacle thereon and rotatable around a second axis. The first and second rollers are relatively positioned so that as the first and second rollers rotate around the first and second axes, the one cutting element aligns with and projects into the one receptacle to thereby cause cutting out of a discrete portion of a sheet material between the first and second rollers. A servo drive is provided for at least one of a) rotating the first roller around the first axis and b) rotating the second roller around the second axis.
