ABSTRACT:
A chip slicer has pivotably mounted chip-forming knives located so that the knife edges are in a plane which passes through the axis of rotation of the knives, as well as through the axis of pivoting. Another improvement is to employ a knife which has a blade which is bent at an obtuse angle to form a first and a second leg. The first leg has a cutting edge and an upper surface which defines a chip path. The second leg is bent with respect to the first leg in the direction of rotation of the knife ring. The knives are mounted to the ring by clamping wedges which are bolted to the knife ring so that they overlie the second leg and so clamp the knife blade by the second leg to thereby substantially remove obstructions from the chip path. A further improvement has chip depth gauges which are positioned in front of the knife edges. The depth gauges have trailing edges in the direction of rotation which extend substantially parallel to the upper surface of the blades. Yet another improvement employs chip knives which are mounted beneath spring loaded knife clamps which can be loosened by partially unbolting, so the blades may be driven laterally through holes in the sides of the knife rings by replacement blades.
