ABSTRACT:
A chipper for cutting uniform chips from a log has a sliver ring mounted on the rotary disc radially outside the cutting blade assemblies, and also has cooperating arcuate wrapper member and special sliver bedknife mounted on the front plate of the chipper housing. The wrapper member is concentric with the sliver ring and extends circumferentially around it for a distance, and also extends axially towards the disc and beyond the proximal face of the sliver ring to define a radial gap between the ring and the wrapper. The sliver bedknife extends across the face of the disc from one end of the arcuate wrapper. The sliver bedknife, the wrapper, and the sliver ring cooperate with one another to limit progression of slivers that are formed from wooden logs at the position of the stationary bedknife.
