摘要：The invention relates to a chipper knife with at least one cutting edge (6) alongat least one of its side edges. The chipper knife is adapted to be mounted in chippers ofthe kind which are used to cut chips of a desired size and shape from pieces of wood ortimber (7) and which comprise a tool, in the form of a plane or conical disc, which isarranged for rotation about an axis of rotation and on which a plurality of such chipperknifes (2) are mountable in such manner that one end of the cutting edge of the chipperknife is located closer to the axis of rotation of the tool than the opposite end of thecutting edge. The cutting edge (6) of the chipper knife is formed between a timber-guiding surface and a chip-guiding surface, the timber-guiding surface having a varyingangle along its length in relation to a plane of rotation in such a way that the angle isgreater at the end of the cutting edge located closest to the axis of rotation decreases inthe outward direction. The chip-guiding surface of the chipper knife also has a varyingangle along its length in relation to a plane of rotation in such a way that the angle issmaller at the end of the cutting edge located closest to the axis of rotation andincreases in the outward direction in order to obtain a cutting edge angle between thetimber-guiding surface and the chip-guiding surface (13) that is essentially constant alongthe whole length of the cutting edge.
