摘要： A debarking blade arrangement is carried by a frame of a tree harvesting head and includes a fixed knife segment that cooperates with three articulated knife segments carried by each of right- and left-hand, articulated debarking arm assemblies which are disposed on opposite sides of a tree stem feed axis. Each arm assembly includes a rear arm section that carries a first knife segment, an intermediate arm section and a front arm section that carries second and third knife segments and is yieldably biased toward the intermediate arm section so as to dispose the second and third knife segments for engagement with a tree stem. A hydraulically-powered arrangement is coupled to each arm assembly for selectively pivoting the entire assembly about a fixed axis and for pivoting the intermediate and front arm sections relative to the rear arm section for keeping the knife segments in debarking engagement with the stem.

摘要： An apparatus and method for machining the surface of logs, in which the log is longitudinally advanced through an opening provided in a rotor disc and the surface of the log is machined by rotatable cutting heads mounted on respective supporting arms pivotably connected to the rotatable disc and rotating therewith around the logs. The cutting heads are rotated around respective axes of rotation, while concurrently the cutting heads rotate with the rotor disc around the log such that the net rotational speed of the cutting heads at the surface of the log is the sum of the speed of rotation produced by the rotatable disc and the speed of rotation of the cutting heads around their respective axes. In the course of machining the logs, the speed of rotation of the rotor disc is varied as a function of conditions at the surface of the log and the rotational speed of the cutting heads around their axes is varied in relation to the rotational speed of the rotor disc to maintain a substantially constant net rotational speed of the cutting heads at the surface of the log.

摘要： A debarking machine having a wood-infeeding side for feeding wood to the debarking machine and a wood-outfeeding side for outputting wood from the debarking machine, includes a line of first to n-th rotary members coupled in series, or a plurality of lines thereof coupled in series, from the wood-infeeding side to the wood-outfeeding side, each rotary member having a debarking blade on an outer surface. The first rotary member is inclined downwardly in a direction toward the wood-outfeeding side from the wood-infeeding side, and the second to n-th rotary members are arranged either horizontally or inclined downwardly in the direction toward the wood-outfeeding side from the wood-infeeding side. An inclined angle of the first rotary member located at an end of the wood-infeeding side is set greater than an inclined angle of the n-th rotary member located at an end of the wood-outfeeding side. Inclined angles of the second to (n-1)-th rotary members are set within a range from an angle no less than the inclined angle of the n-th rotary member to an angle no more than the inclined angle of the first rotary member, and are each set no less than the inclined angle of an adjoining rotary member which is located on the wood-infeeding side.

摘要： A bit with a fiber cutter for a rosser head debarking machine. The bit has a base for mounting the bit onto the rosser head. The striking edge of the bit is connected to the base and comes into contact with bark and removes the bark as the rosser head spins. The bit has at least one replaceable fiber cutter that includes a cutting edge that cuts through the bark or fiber within the bark as the rosser head spins. Preferably, the fiber cutter is disk-shaped and tapered away from the striking edge and cuts through the fiber in the bark in a perpendicular direction to the fiber. The cutter can be connected to the bit by a threaded bolt that is positioned through a hole in the middle of the cutter and into a threaded hole in the bit. The bit can have threaded holes on both sides to allow two cutters to be installed or for the bit to be rotated.

摘要： A debarker head for use in a rotary tree debarking machine has a drive shaft with a polygonal cross sectional shape and a plurality of substantially similar cutting elements with mounting apertures corresponding to the drive shaft shape and sized for slip fit engagement of the cutting elements on the drive shaft so that the cutting elements may be mounted to the drive shaft at a number of rotational positions relative to the drive shaft. Further, the cutting elements have a plurality of arms with cutting knives. The number of arms of at least some of the cutting elements is not an integer multiple of the number of sides of the mounting aperture so that a variety of cutting knife arrangements for debarking various species of logs using the same head may be obtained by adjusting the rotational position of the cutting elements relative to the drive shaft. This design of debarker head can be repaired in the field.

摘要： A method and a mobile unit for barking and/or limbing and chipping as a continuous operation. A log is given a linear displacement movement by means of a feed unit (6) including two in relation to each other displaceable feed rollers in direction towards a chipper (4), and as first step preceding the feed rollers, existing branches are removed by a limbing unit (7) including at least two knife-acting means, displacable in relation to each other in a substantially crosswisely extending plane in relation to the longitudinal and displacement direction for the log, pressed against the peripheral surface of same. During the linear feeding movement of the log, existing branches are sheared or cut off. When performing barking, the feed unit (6) is followed by a rotary barking unit (5) surrounding the log, including a number of barking means with members arranged to take up cutting or frictional contact with the peripheral surface of the log, which by means of centrifugal force during a rotary movement in a plane different from the feeding direction for the log are pressed against the peripheral surface of the log, and by means of a cutting operation remove a layer of bark surrounding the log.

摘要： A method and apparatus for debarking logs of the type having long-fibre bark. In a first debarking operation, rotary cutterheads remove a portion of the mark so as to leave a bark/no-bark, barber-pole pattern on a log's surface. In a second, downstream debarking operation, scrapers on a rotating ring remove the remaining bark.
