摘要： A cutting device includes a frame and a counter construction fitted in the frame. The cutting device also includes a force member rotatably supported to the frame and extending in the radial direction up to the counter construction, overlapping in the axial direction relative to the axis of rotation of the force member. In addition, the cutting device includes equipment for rotating the force member and thereby for cutting material in cooperation with the counter construction. The force member includes a profile for taking the material to be cut against the counter construction for cutting the material.

摘要： A knife projection sensing system for cutting machines having a rotatable surface adapted to retain a plurality of cutting knives. The system employs a plurality of sensors mountable to the cutting machine to be stationary with respect to the rotatable surface. The sensors generate a signal capable of indicating the position of each cutting knife as the knives rotate past the sensors. A microprocessor in communication with the sensors analyzes the signal generated to determine the projection of each knife from a reference surface and to determine if the projection of at least one of the plurality of cutting knives deviates outside preset desirable limits. The projection status of the knives is communicated to an operator by a light display or paper printout. The system can be used to ensure that knives are correctly installed in the cutting machine and to monitor knife position during normal operation. The system can also be used to determine when knives need changing for sharpening. If the projection of the knives exceeds preset limits, the system will automatically shut down the cutting machine to prevent damage.

摘要： The invention is based on the method for the resharpening of knives used in size-reduction machines described in U.S. Pat. No. 5,525,094 in which the knives remain installed in a rotatable knife carrier. With this invention the process has been further developed in so far as the cutting edges S are ground one after another respectively at one stop position of the knife carrier 8 in which the radial ray MS of the cutting circle with the direction mS of the grinding feed v at the knife cutting edges S encloses the clearance angle .phi.. So the invention offers the possibility to choose for the cutting edges any clearance angle matching the properties of the material to be flaked.

摘要： A peripheral drive log lathe having no sliding surfaces susceptible to wear in either the log pinching apparatus or in the knife assembly. All loads are transferred to the frame members through rotary bearings. The knife assembly is self aligning to the thickness W of the veneer cut by the fixed distance W between the noseroll and the knife edge. The idler rolls are mounted on a carriage which can only move in parallel planes as determined by a three point translation scheme. A trio of ball screws and nuts provide synchronized drive to the three points. A rounding actuator controls the knife assembly until the log is rounded at which time the rounding actuator is de-energized and the becomes self aligning.

摘要： A wood chipper having a rotatable drum configured to reduce the size of wood fed into the wood chipper; a sensor configured to sense a speed of rotation of the rotatable drum; and a controller operably connected to the sensor. The controller is configured to cut power to the rotatable drum when the speed of rotation of the rotatable drum drops below a pre-set threshold value. The controller is operably engaged with a centrifugal clutch that is engaged to enable the rotatable drum to be rotated. When the speed of drum rotation drops below the threshold value because debris is slowing down rotation of the drum, the centrifugal clutch is disengaged by dropping engine speed. Disengagement of the centrifugal clutch cuts power to the drum and rotation thereof ceases so that the debris may be cleared.

摘要： An apparatus and a system directed to a towed device powered by a tow vehicle. The apparatus and system include a woodchipper configured to be mounted on a towed vehicle, with the towed vehicle configured to be towed behind the tow vehicle. Additionally, a motor may be coupled to the woodchipper to provide power to the woodchipper. A power converter obtains power from the tow vehicle from a power takeoff coupled to the tow vehicle. Further, one or more power transfer lines connect the power converter with the motor to communicate motor-operating power from the power converter to the motor.
