Abstract: A clamping assembly to hold a woodworking knife in place in a woodworking machine. The clamping assembly comprises a clamping component comprising a body and an actuator. The body has three discrete contact positions distributed thereon: 1) a fulcrum located generally at one end, 2) a knife abutting portion located generally at the other end, and 3) a bearing surface located elsewhere. The actuator is for applying a clamping force to the body along a clamping axis located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis . The bearing surface is a surface wherein a line normal to the bearing surface intersects the line normal to the fulcrum at a position outside of the clamping component at a location farther askew of the clamping axis than the fulcrum.

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: 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 size and shape from pieces of wood or timber (7) and which comprise a tool, in the form of a plane or conical disc, which is arranged for rotation about an axis of rotation and on which a plurality of such chipper knifes (2) are mountable 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 between 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 between the timber-guiding surface and the chip-guiding surface (13) that is essentially constant along the whole length of the cutting edge.

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 clamping assembly to hold a woodworking knife (324) in place in a woodworking machine. The clamping assembly comprises a first clamping component (306), a second clamping component (308) and an actuator (310). The first clamping component has three descrete contact positions distributed thereon: 1) a fulcrum (326) located generally at one end, 2) a first knife abutting portion (325) located generally at the other end, and 3) a bearing surface (330) located elsewhere. The second clamping component includes a surface defining a second knife abutting portion for engaging a surface on said one or more knives that is opposite the surface thereof engaged by the first knife abutting portion of the first clamping component to clamp said one or more knives between the clamping components; and a substantially planar contact surface located to engage the bearing surface of said first clamping component. The actuator is for applying a clamping force to the first clamping component towards the second clamping component along a clamping axis (328) located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis. According to the invention the first clamping component has a larger length in cross section than the second clamping component, such that when positioning the first clamping component against the second clamping component such that the clamping axis of the first and second clamping components are aligned and the bearing surface and the contact surface abut, the fulcrum of the first clamping component is located a distance outside of the second clamping component.

Abstract: The invention relates to a barking device comprising a barking arm (1) and a barking tool (2) which is mountable in a tool seat of the barking arm. The barking tool comprises a convex mounting surface (13), while the seat surface (7) of the barking arm is concave. The barking tool is, with the aid of a connecting means, mountable in the tool seat and displaceable by rotating displacement. The connecting means comprises a screw (18) and a sleeve-like nut (21). The head (20, 23) of one of the con­necting means parts (18, 21) is designed to prevent displacement and rotation.
