ABSTRACT:
A log-slabbing chipper with multiple knife structures distributed about the periphery of a power-driven rotor head. Each knife structure includes a holder and a pair of assemblies mounting double-edge replaceable knives. Each knife is mounted between a clamp and a fixed counterknife. Each knife has a serrated back-bearing surface and each clamp has a correspondingly serrated clamping surface. Adjusting screws exert pressure on the clamps to slide the clamps and the knives with respect to the stationary counterknives to achieve desired precise edge positions.
