Claim 7

The cutting apparatus according to claim 4, wherein each of said side plates having a substantially elliptical said first and second cutters have a same length diameter through hole formed in a lower portion thereof so as to have a minor diameter larger than said same length diameter said apparatus further comprising a pair of cover plates removably mounted to said side plates so as to cover said through hole, said cover plates having holes therein rotatably receiving said first and second cutter shafts, whereby said cutting implement can be removed from said apparatus through said through hole in the axial direction of said first and second cutter shafts together with said cover plates by detaching said cover plates from said side plates.

Claim 8

A cutting apparatus, comprising: a cutting implement including a frame, first and second cutter shafts disposed substantially in parallel to each other, a plurality of first substantially dislike cutters fitted around said first cutter shaft, a plurality of first substantially dislike spacers fitted around said first cutter shaft, said first cutters and said first spacers fitted around said first cutter shaft being alternately arranged and brought into intimate contact with each other in the axial direction of said first cutter shaft, a plurality of second substantially dislike cutters fitted around said second cutter shaft, a plurality of second substantially dislike spacers fitted around said second cutter shaft, said second cutters and said second spacers fitted around said second cutter shaft being alternately arranged and brought into intimate contact with each other in the axial direction of said second cutter shaft, each of said first cutters and each of said second spacers being closely opposed to each other and each of said second cutters and each of said first spacers being closely opposed to each other, so as to hold said first and second cutters in mesh with each other; a motor attached to said first cutter shaft for rotating said first cutter shaft, means for rotating said second cutter shaft in a direction opposite to the direction in which said first cutter shaft is rotated; a stationary plate mounted on a lower portion of said frame of said cutting implement; and a plurality of secondary platelike cutters formed in two rows on said stationary plate in the axial direction of said first and second cutter shafts and disposed immediately below said first and second spacers, each of said secondary platelike cutters in one of said two rows having an upper cutting edge disposed adjacent to a lower circumferential surface of said first spacer and having a lower cutting edge disposed adjacent to a lower circumferential surface of said second cutter, each of said secondary platelike cutters in the other of said two rows having an upper cutting edge disposed adjacent to said lower circumferential surface of said second spacer and having a lower cutting edge disposed adjacent to said lower circumferential surface of said first cutter.
