Claim:
A disc cutting apparatus for removing chips from a wooden work piece, said apparatus comprising: a chipper frame for rotatably supporting a cutting disc that contains a plurality of radially disposed knife assemblies in relation to the front face of said disc; a feed spout mounted in said chipper frame for feeding wood work pieces into contact with the front face of said cutting disc, said feed spout having a distal end located in close proximity with said front face of said cutting disc; a bedknife having a first surface and an opposed second surface that is nonparallel to said first surface, a planar top surface and a planar bottom surface such that said bedknife establishes a truncated wedge shaped structure that tapers downwardly and inwardly from said top surface towards said bottom surface; and a gap formed in said chipper frame at the distal end of said feed spout that compliments the truncated wedge shape of said bedknife, said gap having a pair of opposed nonparallel side walls that engage the first and second opposed surfaces of the bedknife in supporting contact therewith.
