ABSTRACT:
A cutter for cutting continuous stock materials into discrete lengths is disclosed. The cutting device includes a plurality of rotatable cutting tools or blades extending transversely across a cutting zone. The cutting tools are mounted in a common plane, are intermeshed, and are synchronously driven in opposite directions. The cutting zones of the intermeshed cutting tools overlap and thus the cutting device is capable of performing the cutting operation by movement in one direction through the material being cut. The cutting tools have opposed segments that carry cutting edges. In one form of tool, the cutting edges are spaced from the axis of rotation of the cutting tool by a distance that continuously increases in a direction opposite the direction of rotation of the cutting tool. This change in distance can be related to the speed of rotation of the cutting tools and the speed at which the cutting tools are advanced through the material being cut.
