Abstract: A guitar neck joint routing system. The system includes a probe and router assembly comprising a gantry, a probe, and a plurality of routers, and a guitar neck and body nest comprising clamps and vacuum grips for holding a guitar neck and guitar body in place for taking measurements and routing a dovetail joint.

Abstract: A method and system for detecting and controlling the quality of debarking at the surface of a wooden log provide information on main parameters related to the debarking quality of the log surface, including fiber loss and residual bark. The debarking quality detecting method and system involve measurement of three-dimensional profile of at least a portion of the log surface to generate corresponding profile image data, which is processed to generate data indicative of the texture of the log surface. The texture data is then analyzed to generate resulting data on the debarking quality parameters. That quality indicative information can be generated on a continuous basis to provide an objective assessment of the quality performance in real-time in view of target productivity, and may then be used to perform optimal adjustments of the debarker operating parameters, either manually by the operator or automatically through feedback control.

Abstract: An improved method and arrangement for increasing the yield in the production of edge glued laminations for the manufacture of edge glued laminated panels from thin timber. The edge glued laminations are manufactured from planed boards with residual waney edge by longitudinal sawing on an edging line including an upper and lower inlet feed conveyor, and edging machine and an upper and lower outlet feed conveyor, the edging machine preferably including a number of saw blades which are laterally adjustable, and the feed conveyors including endless belts of reinforced rubber 5-10 mm thick, having an underside provided with longitudinal channels with a width of 2-10 mm and a depth of 2-10 mm, the feed conveyors running on a number of tracked rollers adapted to the belts. An edge glued laminated panel based on varying lamination widths manufactured according to the method is also described.

Abstract: A warp stable wood product and methods for detecting the same are provided. The wood product may be sorted based on its morphology, microstructure, macrostructure, and/or chemical composition properties being substantially symmetric relative to at least one or more cross-sectional centroids of the wood product, thereby imparting warp stability.

Abstract: A scanning device for determining the shape of irregular substantially cylindrical objects. Lines of light are projected onto the surface of the object. The position of the images of the lines on the surface are measured at predetermined positions to obtain a three dimensional profile of the object. The device can be incorporated into a log cutting system and the position of the log can be adjusted based on the profile determination to obtain maximum yield from the log.

Abstract: A method and apparatus for positioning a log in a lathe charger for transfer to a veneer lathe for peeling in which the geometrical centerline of the log is first determined by sensing the log in an at-rest position with light sensors or mechanical sensors and then two geocenters where such centerline intersects the ends of the log are determined. The log is then scanned with light scanners while it is rotated on charger spindles about such centerline to determine the optimum yield axis of the log by computer processing of the scan data. Two computed centers where the optimum yield axis intersects the opposite ends of the log are computed and the vectors of such computed centers relative to the geocenters are computed. A common line extending between the computed centers is determined and the displacement angle between such common line and a reference line is computed. The reference line may be a vertical axis or the charger pendulum arm radius.
