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: A self-aligning knife clamping assembly (10) and machine incorporating the same are disclosed. In one embodiment there is provided a knife clamping assembly (10) having an outer clamping component (22), an inner clamping component (24) and a fastening device (14), such as a bolt, therebetween, to permit the clamping components to be releasably clamped together onto a knife element (50) having a knife edge. Positioned between the knife element (50) and the clamping assembly is a biasing element (60), which urges the knife element to enter, or remain in, a preferred position prior to the knife element being immovably clamped into place. In the preferred embodiment the biasing element is in the form of an elastomeric strip.

Abstract: The invention relates to a debarking means for rotation ring type barking machines, and of the type comprising a plurality of swinging arms (1) yield­ably engaging the circumference of an unbarked log and each formed at its free end with a seat (4) for a debarking means (2) detachably mounted by means of a bolt connection (3). The debarking means has a leading edge (7) serving as a cutting edge and a trailing support edge or surface (8) adapted to en­gage a shoulder (5) on the seat (4) to prevent turn­ing of said debarking means relative to the arm. The support edge (8) extends obliquely in relation to the cutting edge (7), more particularly along the entire width of the debarking means and between two side edges of said means which are of different length.

Abstract: A wood working knife (32) for use in a wood working machine, comprising a knife body having a first cutting edge (34) and an opposed second cutting edge (36), the knife body having a first clamping surface (40) and a second clamping surface (38). The first clamping surface has opposed clamping features (48,50) separated by a middle section (52), the opposed clamping features and the middle section being sized and shaped such that, upon the knife body being inserted into a clamping assembly, the clamping forces are localized towards the opposed cutting edges and away from the middle section.

Abstract: The invention relates to a method for forming a round log into a block with two or more flat lateral surfaces. IN the forming, the material to be removed is cut directly into chips in a block-forming assembly which comprises two or more working tools (3). Each of the working tools has the form of a rotary drum or frustoconical body, which on its circumferential surface carries a plurality of chipper knives (4). After the block-forming assembly, the block is fed to a sawing assembly for resawing, and when sawing thick logs the feed rate of the sawing assembly and, thus, also of the block-forming assembly must be reduced. According to the invention, the method comprises removing one or more chipper knives (4) from each of the working tools (3) when sawing thick logs. As a result, the reduction of the rotary speed of the working tools is avoided or limited, which is otherwise necessary to keep the desired chip size. The invention also concerns a blind knife (10) to be mounted in a chipper knife seat (11) instead of a removed chipper knife.

Abstract: A method to control a manufacturing process for cellulose, pulp or similar by measuring the bulk density of the chips supplied to the process. A representative volume of the supplied chips are sampled and supplied to a measuring method, during which the sampled volume is measured as to the dimensions of the chips contained in the volume, the chip bulk density being possibly calculated by means of the measured values. The thus calculated chip bulk density is used to control the forthcoming chip treatment in the process.

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.
