  • Publication number: 20090025829
    Abstract: A knife assembly and chipping knife therefor. The knife assembly includes a knife, and employs an upper clamping member and a lower clamping member for clamping the knife therebetween. The knife has an elongate axis and two spaced apart cutting edges parallel to the elongate axis and defining a first reference plane. The knife is further defined by a plane of reflective symmetry that is perpendicular to the first reference plane and which contains the elongate axis. The knife has a front side and a back side spaced from the front side. The front and back sides terminate in the cutting edges. A deflector ridge projects from the front side and reaches a point of greatest maximum projection of the knife from the first reference plane, the point lying in the plane of reflective symmetry.

  • Publication number: 20040060614
    Abstract: A method and apparatus for planing an article of wood. Specifically disclosed is a cutting head adapted for rotation about an axis, and at least one elongate knife including a linear cutting edge for cutting the wood. The cutting edge terminates at opposite ends of the knife in respective tips. The knife is held by the cutting head so that each tip is rotated about the axis of rotation at the same fixed radius. However, the cutting edge is misaligned by a predetermined bias angle with respect to the axis of rotation. Where a plurality of the cutting heads are stacked or ganged together, preferably, the angle of misalignment for the knives of some of the cutting heads is reversed from the angle of misalignment for the knives of others of the cutting heads.

  • Patent number: 6591878
    Abstract: A method and apparatus for clamping a knife. A front side of the knife includes a recess and the knife is clamped between an outer clamping member adapted to receive the back side of the knife, and a inner clamping member adapted to receive the front side of the knife, the inner clamping member making contact with the front side of the knife at two spaced locations thereon, wherein at least one of the locations is outside the recess and the other is inside the recess, wherein the width of the recess normalized by the overall width of the knife yields a result that is preferably no more than about 0.22.
