Abstract: In the positioning system for an operating cylinder (1), a valve or a set of valves (6; 10, 11) comprises means for allowing a free supply of hydraulic fluid from a pump fluid chamber (8) of a pump cylinder (7) into an operating fluid chamber (2) of the operating cylinder (1), for preventing the backflow of hydraulic fluid from the operating fluid chamber (2) into the pump fluid chamber (8) when the hydraulic fluid pressure on the control side (A) rises above a predetermined pressure limit, and for allowing a free back flow of hydraulic fluid from the operating fluid chamber (2) into the pump fluid chamber (8) when the hydraulic fluid pressure on the control side (A) goes below the predetermined pressure limit. An operating piston rod (3) follows closely the movement of a pump piston rod (9), and the valve or the set of valves (6; 10, 11) prevents pressure fluctuations from transmitting from the operating side (B) to the control side (A). The system can be used for instance in a hole-rotor-type barking machine (16) for positioning the operating cylinders of barking blades (17). The system can also be used for positioning the operating cylinders (1) operating the gripping jaws (19) of a hydraulic gripper (18) of a machine. Furthermore, the system can preferably be used for positioning the operating cylinders of pusher shafts, lift booms and articulated knuckle booms of a machine.

Abstract: A tip for a rotary debarker has a polygonal main body with a front surface and a rear surface, and at least one cutting blade along each of the opposed edges. The main body includes a non-circular mounting boss extending from the rear surface. The main body is mounted to a tip holder that has a non-circular seat for receiving the non-circular mounting boss. The non-circular mounting boss and seat restrict relative movement between the tip and the holder during cutting operations. The tip is reversible relative to the holder to provide two operative cutting blades per tip.

Abstract: A butt reducer machine is provided to remove excess wood from the swelled butt ends of logs. Cutting heads supported on pivoting arms, carried in turn within a rotating frame, are caused to oscillate circumferentially about the portion of the log to be removed. This butt-removal process may be carried out while a log is in motion longitudinally, either before or after the log enters a de-barking machine. The process may also be effected on a stationary log.

Abstract: A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths. The saws are adjusted in response to the computer solution and the log is positioned by a positioner according to a computer generated reference datum. This results in the log being positioned for cutting to the optimum random lengths. A command signal is sent from the computer to the log sorting system, which tracks the position of the random lengths and allows them to be sorted to the appropriate sort storage bin.

Abstract: The present invention relates to a processing means for barking machines of the type having a plurality of swinging arms, each being at an inner end pivotally mounted on a rotatable, annular rotator, while at an opposite outer free end, they carry such a processing means and are actuated by a spring load which strives to pivot the outer end inwards to the axis of rotation of the rotator. The processing means comprises a front, a rear, an upper and a lower surface, which are designed in such manner that an edge serving as a processing edge is defined between the front and the upper surface. The, lower surface is formed with an engaging means which is adapted to engage a matching formation in a seat in the outer end of the swinging arm. The rear surface acts as a supporting surface which serves to abut against a corresponding swinging arm supporting surface which is directed forwards or obliquely forwards against the direction of feed of the logs. The engaging means comprises a ridge or a groove and is rectilinear and elongate in such manner that its total length exceeds its height or depth, and preferably also its width, at least by a factor ten. The engaging means further extends at an acute angle of at least 10° in relation to the rear surface.

Abstract: 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.
