    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: A sharp edged knife stop can secure the position of knife blades in a cutting or chipping system and prevent the separation of knife blades. The sharp edged knife stops can also assist in the cutting or chipping and lower the amount of debris build up that would occur with the use of traditional knife stops. The sharp edged knife stop has the same inclination angle as the knife blades and the same difference in knife edge height as the knife blades above that of a retaining ring height.

    Abstract: The invention relates to a multiple screw driving machine comprising a plurality of individual screwdrivers which are arranged on a body or in a housing ( 8 ) and which each comprise a spindle or shaft ( 7 ) which is rotatably mounted in the housing and which at an outer front end carries a screw driving tool ( 10 ) for engagement with a screw means. Each of the screwdrivers are separately drivable by a common motor ( 1 ) via a driving wheel transmission comprising a primary driving wheel ( 5 ) for each screwdriver. The primary driving wheel ( 5 ) is rotatably but non-displaceably mounted on the shaft ( 7 ) of the respective screwdrivers whereas a driver element ( 14 ) is non-rotatably but displaceably mounted on the shaft ( 7 ) and is displaceable with the aid of an operating means ( 16 ) towards and away from the primary driving wheel ( 5 ). The primary driving wheel ( 5 ) and the driver element ( 14 ) each have mating and mutually facing engagement means ( 19, 20 ).

    Abstract: A wood processing device having a spinning wood processing head having one or more spaced apart knives mounted on said spinning head for processing wood. The knives, upon contacting said wood, form a curved cut surface in said wood being processed. At least one limit surface is adjustably mounted between said one or more knives on said spinning head, said limit surface being sized and shaped to limit abnormal movement of said wood during processing. An adjustor for adjusting a position of said limit surface is provided to permit said limit surface to limit abnormal movement of said wood over a range of operating conditions. In a preferred embodiment the limiter is curved. A method of adjusting a wood processing head is also disclosed.
