Abstract: A knife includes first and second edges, a ridge, a concave surface, and a planar surface. The edges are defined by intersections of outer edge forming surfaces on an outer side of the knife and inner edge forming surfaces on an inner side of the knife. The ridge is on the inner side and the crest of the ridge is parallel to the first and second edges. The concave surface is between an inner edge forming surface and the ridge, and the planar surface is adjacent to the concave surface and between that first inner edge forming surface and the concave surface. A reference plane intersects the first and second edges, and a distance between any point on the concave surface and the reference plane is not less than a distance between any point on the planar surface and the reference plane.

Abstract: A first side of the blade has a thickened blade edge section adjoining the cutting edge, which presents work edges extending in the blade cross-direction and at right angles to the cutting edge. The blades are designed to be mounted on a rotary tool in the form of a disc, drum or truncated cone. The first side of the blade has a crude unfinished surface or work edges extending in the blade length direction, i.e. parallel to the cutting edge. An independent claim is also included for a method for manufacturing the blade.

Abstract: The invention relates to a chipper knife for chippers of the type comprising a tool ( 12 ) which is rotatable on an axis of rotation and is in the form of, for example a drum, disc or truncated conical body, which supports a plurality of such chipper knives. The chipper knife comprises at least one cutting edge ( 1 ) which is formed between a flank ( 2, 2 ') and a chip guiding surface ( 4, 4 '), and two opposite main surfaces ( 3, 3 ') which are adapted to abut against and be retained on the opposite seats ( 14, 15 ) of a holder ( 9, 10 ) on the tool. At least one main surface ( 3, 3 ') of the chipper knife which is located on a wood side of the chipper knife comprises a cross-sectionally convexly bent surface portion ( 6, 5 ') which connects to and extends backwards from the flank ( 2, 2 ') and the chord of which constitutes at least 20%, preferably at least 30% and, most preferably, at least 40% of the total cross-sectional length of the chipper knife. The invention also relates to a holder for such a chipper knife.

Abstract: The invention relates to a chipper knife with at least one cutting edge (6) along at least one of its side edges. The chipper knife is adapted to be mounted in chippers of the kind which are used to cut chips of a desired siz e and shape from pieces of wood or timber (7) and which comprise a tool, in th e form of a plane or conical disc, which is arranged for rotation about an axi s of rotation and on which a plurality of such chipper knifes (2) are mountabl e in such manner that one end of the cutting edge of the chipper knife is located closer to the axis of rotation of the tool than the opposite end of the cutting edge. The cutting edge (6) of the chipper knife is formed betwee n a timber-guiding surface and a chip-guiding surface, the timber-guiding surface having a varying angle along its length in relation to a plane of rotation in such a way that the angle is greater at the end of the cutting edge located closest to the axis of rotation decreases in the outward direction. The chip-guiding surface of the chipper knife also has a varying angle along its length in relation to a plane of rotation in such a way that the angle is smaller at the end of the cutting edge located closest to the axis of rotation and increases in the outward direction in order to obtain a cutting edge angle betweenthe timber-guiding surface and the chip-guiding surface (13) that is essentially constant along the whole length of the cutting edge.

Abstract: The block comprises a flat or cone-shaped plate with cutting blades (2) mounted on it so that one end of the blade cutting edge (6) is closer to the block rotation axis than the other end. The cutting edge is bordered by a timber guide surface and a chip guide surface (13), the timber guide surface having an angle relative to its rotation plane which varies over its length, so that the largest angle is at the end of the cutting edge closest to the rotation axis and the angle then reduces in the outwards direction. The chip guide surface also has an angle relative to its rotation plane which varies over its length, so that the angle at the end of the cutting edge closest to the rotation axis increases in the outwards direction, ensuring that the cutting edge angle between the timber and chip guide surfaces remains essentially constant over the entire length of the cutting edge.
