Abstract
A cutting apparatus for cutting a material, such as leather, having a drum, a plurality of rollers, a cutter and a pair of belts. The drum includes a drum surfaces and rotates about an axis. The cutter has a cutting edge that is in contact with the drum surface and is oriented generally perpendicular to the axis. The rollers are arranged generally parallel to the axis and support the belts for rotation thereon. Each of the belts is disposed on an opposite side of the cutting edge and is positioned such that a portion of each belt extends about a corresponding portion of the drum surface forward of the cutting edge. The portion of the belts and the portion of the drum surface are positioned to frictionally co-engage the material and drive the material into contact with the cutting edge.
Claims20
A cutting apparatus for cutting a material, the cutting apparatus comprising:
- a drum having a drum surface, the drum rotating about an axis;
- a plurality of rollers arranged generally parallel the axis;
- a cutter having a cutting edge that is in contact with the drum surface and generally perpendicular to the axis;
- and
- a pair of belts mounted to the rollers, each of the belts being disposed on an opposite side of the cutting edge, a portion of each of the belts extending about a corresponding portion of the drum surface forward of the cutting edge;
- wherein the portion of the belts and the portion of the drum surface are positioned to frictionally co-engage the material and drive the material into contact with the cutting edge to thereby permit the cutting edge to form a cut in the material.
A cutting apparatus for cutting a sheet material into material strips of a predetermined width, the cutting apparatus comprising:
- a drum having a drum surface;
- a frame supporting the drum for rotation about an axis;
- a cutter bar mounted to the frame;
- a plurality of cutters associated with the cutter bar, each of the cutters having a cutting edge that is oriented generally perpendicular to the axis, each of the cutting edges being spaced apart by a distance that is equal to the predetermined width of the material strips;
- a plurality of rollers arranged generally parallel the axis;
- and
- a plurality of belts mounted on the rollers and arranged such that one of the cutters is disposed between a pair of the belts, a portion of each of the belts extending about a corresponding portion of the drum surface forward of the cutting edges of the cutters;
- wherein the portion of the belts and the portion of the drum surface are positioned to frictionally co-engage the material and drive the material into contact with the cutting edge to thereby permit the cutting edges to form the material strips.
