Abstract
A disc cutting apparatus for chipping wood chips from a log includes a chipper frame, a rotary cutting disc having a plurality of substantially radially disposed knife assemblies in relation to a proximal facing side of the disc and a feed spout into which a log is fed into the chipper apparatus. The apparatus further includes a bedknife, the bedknife having a first surface and an opposing second surface that is nonparallel to the first surface such that a wedge is produced between the first surface and the second surface for fitting within a corresponding nonparallel gap in the chipper frame. The bedknife further includes at least one secondary trimming edge for more complete reduction of wood chipped and for reducing the size of slivers formed.
