The invention relates to a machine tool having a gantry that is movable along an X axis and having a vertical spindle supported by the cross-member of the gantry. The cross-member comprises two beams that are spaced apart in the X axis direction and that have facing inside faces. Two carriages are mounted to slide on said facing faces, on opposite sides of a vertically movable cursor-carrier. The tool-carrier spindle is carried by a cursor mounted to slide on the bottom face of the cursor-carrier and movable along the X axis. Movements of the carriages, of the cursor-carrier and of cursor are under numerical control. The tool-carrier spindle can move in the X axis direction without it being necessary to move the gantry.

A prismatic wood compression molding method capable of easily producing long-sized lumber usable as pillars or like by compression molding. The method is characterized by comparing the steps of: using a plurality of rigid plate-like bodies such as metal plates to compress an outer face of wood throughout length thereof to compression-mold it into prismatic wood which is polygonal, such as rectangular or hexagonal, in cross section; restraining the plate-like bodies by a restrain jig so as to hold flat surfaces of the prismatic wood in a state in which they are compressed by the plate-like bodies; and applying a heat treatment to the prismatic wood held in the compressed state by the plate-like bodies and the jig so as to permanently fix the shape of the prismatic wood.

A system for reconditioning barrels comprising: a robot arm; a router assembly for routing the inside surface of a barrel; and a laser assembly for measuring the inside profile of a barrel, wherein: the router assembly is fixedly attached to the robot arm; and the laser assembly is removably attached to the router assembly thus allowing the laser assembly to be removed whilst the barrel is being routed in order to protect the laser from airborne particles and vibrations from the router.

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.

A sawing apparatus for a wood products sawing system comprises a frame, a sawing table, a workpiece clamping element, and an overhead saw assembly. A workpiece can be supported on the sawing table and releasably secured to the table by the workpiece clamping element. The overhead saw array is supported by the frame and includes a saw driver and a row of at least three saw assemblies so to sever the workpiece along the cut line by movement of the saw blades along two dimensional paths. A variable width sawing table comprises a driving assembly and a row of support arm assemblies mounted to the frame member and coupled to the driving assembly for movement to at least first and second positions.

A lumber processing system for cutting lumber into predetermined shapes broadly includes a scanning section, a computer section and a cutting section. Incoming lumber is scanned in the scanning section using two-color cameras capturing images first under normal lighting and second under ultraviolet (black) lighting for illumination of pre-marked defects. Images are processed in the computer section to produce a polygonal model of the lumber. A series of auxiliary packing computers review the model and determine separate solutions for cutting the lumber. Parts are then ‘punched’from the lumber in the cutting section utilizing high power lasers cutting from both sides of the lumber simultaneously.

Embodiments of the present invention provide a wood processing machine adapted to cut wood workpieces along multiple optimized cutting paths.

The first saw assembly is adapted to cut the workpiece along the first optimized cutting path and the second saw assembly is adapted to cut the workpiece along the second optimized cutting path.

A method for producing a processed substantially continuous veneer ribbon is provided. The method comprises providing a plurality of debarked wood logs. A substantially continuous veneer ribbon is separated from each of said plurality of debarked wood logs. The substantially continuous veneer ribbons is conveyed to a plurality of storage locations.

A method is provided for treating the decorative face of a panel to simulate the visual effect of a distressed panel. The decorative face may include at least a layer of wood or the like. The method may involve passing the panel with respect to two or more distressing tools. The passing may be performed in an automated way by first driving means. The method may also involve advancing the distressing tools intermittently toward the moving panel to apply distress marks. The intermittently advancing may be performed in an automated way by second, third and optional further driving means. At least one of the passing of the panel and the advancing of the distressing tools toward the moving panel may be performed according to an irregular rhythm in order to obtain irregularly spaced distress marks. At least one of the first driving means, the second driving means, the third driving means, and the optional further driving means is steered by and therefore coupled to program means.

A indicia carrying element for marking timber and more especially logs possessing a indicia carrying body bearing such indicia and having on one side thereof clips for attachment to the head of an applicator hammer in peripheral grooves therein for prior to driving said element into timber, whereas the other side of the element is provided with spurs to be driven into the timber. The clips are arranged in spring regions like lugs in the plate-like indicia carrying body, and such regions are for instance defined by slots in the indicia carrying body. This means that such indicia carrying elements may be reliably clipped onto the standard head of an applicator hammer without there being any danger of the clips breaking off.
