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 concerns a barking tool for barking machines of the type having a plurality of swinging arms, each being at an inner end pivotally mounted on an annular rotator which is rotatable about an axis of rotation, and each having at a free outer end a processing edge. The processing edge is defined between a front and a top surface, which is adapted, during barking, to make an acute angle with the circumferential surface of the log. The barking tool further has a bead, which is located on the top surface in an area adjacent to the end of the processing edge furthest down in the feeding direction. The bead is essentially arcuate in such a manner that its height above the top surface successively increases from an area adjacent to the processing edge perpendicularly backwards therefrom and, more specifically, the height is adapted such that the bead during normal barking is positioned between a certain minimum and a certain maximum, and preferably essentially uniform, distance from the barked circumferential surface of the log independently of its diameter.

Abstract: A knife for a disk chip cutting machine which is mounted between a carrier part and a clamping part and which includes a chip breaking surface extending into an opening adjacent an outer surface of the carrier part. The chip breaking surface includes a concave portion which terminates in a rib which extends outwardly and downwardly with respect to an interface between the knife and the carrier part with the concave portion being oriented to direct cut chips in a direction away from the outer surface of the carrier part during use.

Abstract: A cutting blade for working logs to timber form while simultaneously removing wood chips which includes a pair of adjacent recesses formed in the periphery of the blade. A knife is bolted in the cutting blade in a first recess and a wear insert is separately bolted to the cutting blade in the adjacent recess. The bolts are countersunk so as not to extend outwardly from the knife or wear insert.
