    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, f or example a drum, disc or truncated conical body, which supports a plurality o f 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 wo od side of the chipper knife comprises a cross-sectionally convexly bent surfac e 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 t he chipper knife. The invention also relates to a holder for such a chipper kni fe.

    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.

    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 knife for disk type chip cutter machines with a circular rotatable cutter disk (10) on its first axial side being provided with several knives running from the disk centre to its periphery. An opening (14) is provided in the disk in connection with each knife. The opening (14) has a chip guiding surface to guide separated chips to the other axial cutter disk side. The knife includes a knife carrier, on which the knife is fixed between a first carrier part (18) provided essentially in line with the first axial cutter disk surface and second carrier part (16) extending downwards in the opening from said cutter disk surface into the cutter disk inside and being a part of the chip guiding device. The knife (12) is on its side facing the other carrier part provided with a chip breaking surface (22) passing the other carrier part (16) into the opening and protecting said carrier part from wear in that the separated chips by means of the chip breaking surface are guided in a direction away from the carrier part.
