ABSTRACT:
True zero-clearance cutting on a commercial scale is provided via a cutting area including a sacrifice material that is relatively softer than the cutter. One example is a cutting system which is capable of cutting a material such as, for example, tape or paper, into a fiber or powder. Destruction of the material is further enhanced by advantageous strategic patterning of cutting edges on a rotary cutter, and further by secondary shredding features. For example, on the same axis as the rotary cutter, may be disposed, one on each end, rotating secondary shredders that receive material that has been cut by the rotary cutter as well as material that has escaped cutting by the rotary cutter. A variety of materials, of different thicknesses and types, may be reduced to a dust or powder-size. A single destruction machine advantageously may receive (with minimal operator intervention) a mixed input load, such as a mixture of a combination of paper (including paper that is folded, ripped, stapled, or otherwise irregular), CDs, DVDs, polyester, plastic cards, SMART cards, wood, and/or other generally-planar materials.
