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.

A chipper has a knife clamped between a clamp and a counter knife that sits on a holder. The knife, damp, and counter knife are collectively positioned in a machined area formed in a holder that is in turn within a larger recess formed in a chipping disk or chipping drum.

A first fastener secures the knife holder to the chipping disk, a second fastener secures the clamp to the knife holder, and a third fastener secures the counter knife lo the knife holder. The knife comprises a ridge which is formed by the termination in two straight lines which form a triangle shape on the bottom of the knife. These straight lines reduce the manufacturing cost of the knife and provide support for the knife to locate. The knife is also manufactured without 100% grinding of all services, which is unique in that this reduces manufacturing costs dramatically.

The present invention relates to a knife, knife holder and knife assembly for cutting and shaping wood logs. The knife assembly provides an improved knife stability and a flexible adjustment of the different components of the knife assembly. The present invention allows both the underside clamping and the topside clamping of the knife assembly to a support tool and provides a method for both clamping processes.

A device and method for reducing a size of feed material. The device has a knife ring that is stationary within a housing or rotates around an axis. The knife ring has rod-shaped knife carriers that are disposed concentrically around the axis in an axis-parallel position at a mutual circumferential distance from each other and that form an inner circumferential surface of the knife ring with their sides facing the axis. Each knife carrier having a receptacle for fastening a flaking knife. The flaking knife protruding by its edge between two knife carriers into the flaking chamber. A measuring instrument includes at least one distance sensor that measures a distance of the inner circumferential surface and/or the edges of the flaking knives from the at least one distance sensor.

A no weld replaceable cutting tooth holder system facilitates replacement of cutting teeth on a cutting disc with improved durability, balance, and resistance to connection defects. The system includes a cutting disc and a holder having a connector and a socket. The holder is secured to the cutting disc without welding. The socket is configured for securement of a cutting tooth onto the cutting disc.

The inertial force wood cutting device includes a trailer and a fuel engine which is fixed to the trailer by bolts. A cutting cabin is fixed to the trailer by bolts. A first and second rotating shaft are rotatably arranged in the cutting cabin. At least two cutting blades are arranged on the first and second rotating shaft in a sleeving manner. A second and first rotating shaft gear are fixedly arranged at ends of the first and second rotating shaft through keys. The fuel engine drives the flywheel to rotate through the driving belt. The flywheel will be meshed and driven by the first and second rotating shaft gear and a gear coaxial with the flywheel. When the flywheel reaches a certain rotating speed, a powerful inertial force will be generated. Wood is fed from the feeding hopper, and wood moves down to be cut by the cutting blades.

A wood chipper knife includes a knife body and, in relation to a vertical axis of the wood chipper knife, at least one cutter side, which comprises a top cutting edge portion and a bottom cutting edge portion that intersect to form a cutting edge. The bottom cutting edge portion includes a planar wood attacking portion, which begins at the cutting edge and towards the knife body is followed by a recess. The recess is a pressure release recess, which, from the wood attacking portion, abruptly falls to a bottom of the pressure release recess, and which stretches from the wood attacking portion to the knife body. The knife body comprises a chip guiding portion, which, from the pressure release recess, rises towards the knife body.

A method and a device for adjusting a knife assembly of a knife ring to a predetermined knife projection, wherein the knife assembly is designed to be arranged in the knife ring at a chip angle , relative to the inside of the knife ring. The knife assembly is formed by a knife holding plate and a chipping knife which are positively connected with one another in a predetermined, relative target position. A knife assembly to be adjusted is provided, wherein the knife holding plate and the chipping knife are displaceable relative to one another. The knife holding plate is displaced in its plane, transversely to its direction of longitudinal extension towards its rear edge, against a first stop. The chipping knife is displaced in its plane against the stop surface of a second stop, until the predetermined knife projection has been reached.

The invention relates to a comminuting machine (8) with a rotor system, in particular a knife ring flaker, in which the feedstock is conveyed pneumatically in the axial direction into the central region of the rotor (10) and is conveyed in the radial direction to the comminuting tools arranged around the rotor (10) in the manner of a ring. In order to uniformly wear the knives extending in the axial direction in such devices, it is proposed to provide in the central region (14) an insert (15) which is rotatably driven by a motor (22) and which has separate chambers (16, 17) with which the feedstock entering said chambers is dispensed at axially and radially to different regions. This insert (15) can, in particular, be designed as a rotor, which has a plurality of chambers which are especially shaped in the cross-section in the manner of a circular sector.

A system and method are provided for producing wood curls with reliable consistency and resiliency. Moisture content of wood blocks is determined and a plurality of cutting knives are installed on a disc of a curling machine and set to extend about 0.012 inches from the face of the disc. The wood blocks are fed through the curling machine and the feed rate is set based on the moisture content of the blocks and the sharpness of the cutting knives and readjusted based on the resiliency of previously cut curls in order to produce wood curls of a desired resilience.
