Abstract: A device for delimbing trees includes two pairs of opposing curved limb-stripping levers including curved cutting blades for engaging and encircling the trunk of a tree to remove limbs therefrom, and a bottom cutting blade positioned to remove limbs from a lower portion of the tree. The bottom cutting blade is movably mounted so as to move in response to forces imposed on the bottom cutting blade by a tree being pulled through the device. In one embodiment, the bottom cutting blade is vertically movable and is biased upward by a spring device. In another embodiment, the bottom cutting blade is pivotally mounted so as to be pivotable forward and rearward, and an impact tool is arranged to periodically transmit impact forces to the bottom cutting blade in a forward direction so as to drive the blade through a limb.

Abstract: A trimming device and method maintains a first trimming member of a tree harvester head at a preselected transverse position relative to a tree trunk during relative longitudinal movement of the tree trunk. A first control device having a tree trunk engaging portion movably connected to the first trimming member selectively establishes the relative transverse position of the first trimming member and the tree trunk. An actuator urges the tree trunk engaging portion into engagement with the tree trunk and the first trimming member at the preselected transverse position.

Abstract: The invention concerns a barking tool for barking machines of the type having a plurality of swinging arms, each being at an inner end pivotally mounted on an annular rotator which is rotatable about an axis of rotation, and each having at a free outer end a processing edge. The processing edge is defined between a front and a top surface, which is adapted, during barking, to make an acute angle with the circumferential surface of the log. The barking tool further has a bead, which is located on the top surface in an area adjacent to the end of the processing edge furthest down in the feeding direction. The bead is essentially arcuate in such a manner that its height above the top surface successively increases from an area adjacent to the processing edge perpendicularly backwards therefrom and, more specifically, the height is adapted such that the bead during normal barking is positioned between a certain minimum and a certain maximum, and preferably essentially uniform, distance from the barked circumferential surface of the log independently of its diameter.

Abstract: A delimber suitable for mounting on a logging skidder. The delimber comprises a series of delimbing/clamping elements and hydraulic actuators for moving the delimbing/clamping elements between an open and a closed position. Each of the delimbing elements comprises a clamping surface and a cutting edge. In the closed position, the delimbing elements hold a bunch of trees and the cutting edges penetrate the trees. Moving the delimber along the trees causes the cutting edges to cut the limbs off the trunks. In another aspect, the delimber includes a tilt feature for topping the trees.

Abstract: A log peeler comprises a log peeling knife assembly 10 attached to a pulling cable 12, the pulling cable 12 being reeved around a powered cable drum 14. The pulling cable is attached at each end of the knife assembly so that the knife assembly will be pulled straight along a longitudinal line perpendicular to the orientation of the knife assembly. The powered cable drum 14 may be an engine or motor driven winch, where the engine or motor is an integral part of the assembly that includes the cable drum. The cable drum 14 is powered by a portable and detachable engine, such as a chain saw assembly 16. A remote control 82 may be located at or near the knife assembly so that the operator can engage or disengage the powered drum, as by closing or opening the chain saw trigger 17 through the action of a controller mechanism 84. Control 82 and controller mechanism 84 may be connected by a power cable or the controller mechanism 84 may be actuated by signals transmitted from control 82 through the air, such as infrared or radio telemetry signals.

Abstract: The invention relates to a self-propelling branch remover with the aid of which relatively large branches on trees, but even whole trees, can be gripped and capped. For this purpose, either so-called felling saws have previously been used, which were attached to the front end of a hydraulic crane and gripped the trunk with claws and sawed it off using a pivotable capping saw. The other solution was that of a worker who was lifted in a lifting basket up to the relevant place and carried out the work there manually using a saw. In both cases, the sawn-off parts dropped down in an uncontrolled manner since even the felling saws did indeed hold the piece tight, but could not hold it in the original position since they could not be used to transmit a torque to the crane arm. The attachment was effected by means of two universal joints. In the present case, this is prevented in that a connection between the felling saw unit and the machine frame is selected, which can absorb both bending forces and torques. For this purpose, the felling saw unit is attached so as to be rotatable and pivotable in a controlled manner relative to a torsion-resistant, jointless telescopic crane arm such that the entire work can be carried out by remote control from the driver's cab of the self-propelling branch remover. This avoids complex cordoning-off and safeguarding work.

Abstract: High powered lasers are used to score the bark on logs before they are mechanically debarked. Typical of the lasers employed are multi-kilowatt CO.sub.2 industrial lasers. A high powered laser beam is brought to a focus just above the surface of the bark on the log. A jet of compressed air is blown coaxially with the beam and facilitates the beam's formation of a narrow slot in the surface of the bark. Logs are advanced and rotated by a plurality of parallel augers extending across the base of a trough. The lasers are positioned in a gap beneath and in between sets of augers. The beam's focus may be adjustable with respect to the bark's surface. The motion of the log with respect to a laser head produces a spiral cut along the surface of the log which slices the long fibers in the bark,
