  • Cutting tool having means for heating a workpiece
    Patent number: 4453437
    Abstract: A cutting tool has a plurality of cutting teeth. An electric voltage is applied between adjacent teeth so that a localized heating of the workpiece occurs at and around the cutting tips, in order to facilitate the cutting step. The voltage may be varied in such manner as to prevent or induce non-linear cutting.

  • Saw unit having mutually displaceable saw parts
    Patent number: 4436009
    Abstract: A saw unit, especially for wood machining, comprises two saw parts, the sawteeth alternately connected to one or the other saw part. The saw parts are mutually displaceable in the direction of tooth travel and/or in the direction of travel of the object being sawed to adjust the relative positions of the teeth. Thus, the cutting effect can be varied at both saw parts. Thus, the side-forces in the saw cut can be controlled in a desired way during sawing to enable the saw unit to be steered in a desired manner.
