System for cutting sheet material
First Claim
1. A system for cutting sheet material, said system comprising:
- a first roller having at least one cutting element thereon and rotatable around a first axis; and
a second roller having at least one receptacle thereon and rotatable around a second axis, the first and second rollers being 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, wherein the cutting element has a cutting edge with a straight portion that is substantially coincident with a line extending radially from the first axis.

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.

10. A system for cutting sheet material, said system comprising:
-
a first roller having at least one cutting element with a cutting edge thereon and rotatable around a first axis;
a second roller having at least one receptacle thereon and rotatable around a second axis, the first and second rollers being relatively positioned so that as the first and second rollers rotate around the first and second axes, the one cutting element projects into the one receptacle to thereby form a discrete cutout that is separated from a sheet material between the first and second rollers and has a shape corresponding to the shape of the cutting edge; and
a pad which resides at least partially within the receptacle that urges a discrete cutout formed by the first and second rollers away from the second roller. - View Dependent Claims (11, 12, 13, 14)

15. A system for cutting sheet material, said system comprising:
-
a first roller having at least one cutting element thereon and rotatable around a first axis; and
a second roller having at least one receptacle thereon and rotatable around a second axis, the first and second rollers being 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 roller, wherein the cutting element has a cutting edge and the receptacle is bounded by an edge, wherein at least one of a) a portion of the cutting edge is substantially coincident with a line extending radially from the first axis and b) a portion of the edge bounding the receptacle is substantially coincident with a line extending radially from the second axis. - View Dependent Claims (16, 17)
