Abstract: The present disclosure relates to a method and device for evaluating a wooden board with an elongated direction. Data indicating fiber orientation over the surface of the board is acquired and for a number of board sub-portions a nominal local modulus of elasticity, MOE, is determined based on the fiber orientation data and a nominal material parameter. A nominal global MOE in the elongated direction for the wooden board as a whole is generated and compared with a secondary global MOE. Based on the fiber orientation data and this comparison an estimated local modulus of elasticity, MOE, in said elongated direction is generated for a number of board sub-portions. This data may be used e.g. for reliable strength grading of wooden boards.

Abstract: A lathe having first and second support walls that support pairs of vertical and elevated vertical guides, and having frames that support horizontal guides. Trunnions are mounted on the vertical guides and support a log peeling assembly. A structure supporting back-up powered rollers is mounted on the elevated vertical guides. First and second spindle assemblies are mounted on the horizontal guides for movement between a first working position where a log to be peeled is gripped and rotated, and a second working position where the log continues its rotation into a knife extending from the log peeling assembly to produce veneer. When a predetermined log diameter is reached the first and second spindle assemblies release and return to the first working position to grip another log, while the log being rotated continues to be peeled until it reaches a minimum core diameter.

The contour of the log to be peeled is determined and the peeling axes at the ends of the log are determined by simulating the veneer yield. The desired veneer yield is determined at least as two veneer products having their own grades. These desired veneer products serve as basic values for the optimizing calculation. The maximum grade of the veneer yield is calculated, based on the dimensions and grades of the veneer products, as well as by iterating the places of the peeling axes and simulating the peeling process. When the peeling axes of the log ends giving the maximum grade yield have been found, the log is placed according to these peeling axes in the lathe and peeled into a veneer web to be cut with a clipper into said desired veneer products.

Abstract: A process for cutting out decorative, artistic designs, and the three-dimensioned decorative and artistic products produced thereby which are incorporatable into articles of manufacture. The process creates relief designs by angle cutting, at predetermined and variable cut-angles and predetermined and variable cut-widths. The decorative cut-out piece, cut from a base piece, is one-directionally removable and one-directionally insertable into the aperture created when the piece is cut from the base piece. The cut-out piece inserts into the corresponding aperture a distance which is determined by a combination of cut-angle and cut-width. The maximum cut-angle and the maximum cut-width is limited by the thickness of the base piece. The cut width is substantially equal to the saw blade cut width or the width of the cut produced by any appropiate cutting device.

Abstract: A method of creating a decorative inlaid floor includes the first step of providing a cutting implement, such as a router, which is operable to machine an inlay recess in a finished wood floor. The next step is to position the router over a section of the floor and move the router in a particular manner so that the desired inlay recesses are machined. The operating and movement step requires that the decorative pattern be predetermined and a control program or NC tape be generated so as to control the drive motors which are associated with each of four slide assemblies. Once the desired inlay recesses are machined into the main floor, the control program is modified by scaling it up to a larger size and is then utilized on a panel of a contrasting material. A typical example would be to select a contrasting wood for the inlay elements. The reprogrammed router is then located over the second material panel and operated so as to machine a larger inlay recess in that second material panel.

Abstract: Defects in wooden boards, such as knots, knotholes or cracks, are repaired by forming an opening in the board at the site of the defect and forming a plug that fills the opening. In some forms of the invention the opening has a shape which interlocks the plug to the board. In another form of the invention, the plug is held in place by a transversely extending resilient member that is embedded in the plug and which is under tension which causes edge portions of the member to bite into or bear against the adjacent wood. Forming the opening includes cutting away bark encasement tissue that may adjoin the defect which encasement can cause a discoloration upon painting of the board and may eventually loosen. In some forms of the invention, cracks are repaired by making plural saw cuts along a crack to form the opening with the saw having a different angling relative to the board during each saw cut.
