摘要： A method and apparatus for maximising value when breaking down a tree stem, log, cant, flitch or slab to sawn timber which includes determining an acoustic velocity value and determining density profile information across the width of the stem, log, cant or slab. The density profile information determined includes a position of minimum density in the stem, log, cant or slab. This enables the prediction of a stiffness profile across the stem, log, cant or slab from the acoustic velocity and the density profile information across the stem, log, cant or slab. The stiffness profile and the position of minimum density in the stem, log, cant or slab can be used to generate a sawing pattern for cutting the stem, log, cant or slab. The sawing pattern is offset by the position of the minimum density for a more useful yield of sawn timber.

摘要： A wood product assembly includes a cutter and skewing assemblies. A cutter positioning body is movable by the slewing assembly along a slewing axis. A spindle housing is mounted to the cutter positioning body for pivotal movement about a pivot axis. A spindle, to which a cutter, such as a sawblade or chipper head, is affixed, is mounted to the spindle housing for rotation about a spindle rotation axis by a drive assembly. The drive assembly includes a fixed position drive motor and a drive shaft assembly. The drive shaft assembly comprises a hollow drive shaft sleeve and a drive shaft. The drive shaft sleeve extends at least part way through the drive motor and is rotatable by the drive motor. An end of the drive shaft is slidably housed within and rotated by the drive shaft sleeve. The skewing assembly is coupled to the spindle housing to position the spindle rotation axis to a selected angular orientation to position the cutter at a selected skew angle.

摘要： The invention relates to a method for cutting a log into pieces. The log is cut into pieces with at least two nearly diametrical cuts (S1, S2), where the outermost lie essentially symmetrically around the pith of the stock. Each so-obtained plank is edged (S7, S8) with the outer side as a reference for the trimming direction. Two planks are formed through a cut (S9, S10) being placed near to the pith essentially parallel with each edged outer side. The cutting is performed on the outermost part of the log with the alignment cut (S3, S4) essentially parallel with the nearly diametrical cuts (S1, S2) preferably in the same operation as the cutting into pieces with the nearly diametrical cuts. Each block with the alignment cut (S3, S4) is conveyed through at least one twin-bladed saw, the cuts of which are inclined with respect to the base surface of the block, for example 30° and cut essentially radially symmetrically around the position of the pith. This can be performed twice with different inclinations in a twin-bladed saw.

摘要： The present invention is directed to a process whereby low-grade lumber, (i.e., lumber having surface defects such as knots, voids, wane, and bark pockets, and warp defects such as twist, bow, crook and sweep), is converted to higher grade lumber and panel products. The process of the present invention involves first categorizing low-grade lumber, arranging a specified number of the categorized low-grade lumber side by side in a manner which offsets the surface defects on adjacent lumber by a minimum distance, and then face-laminating the categorized low-grade lumber together to form a cant. Warp defects such as bow, twist and crook are also offset in the arrangement of the cant and are straightened through the clamping and bonding process. The cant is then re-sawn to produce new, laminated wood products of a higher grade, each new laminated wood product including portions of the original lumber. The wood products may be structural dimensional lumber, 2×4 to 2×12 studs, and panels varying in thickness and width.

摘要： The invention comprises engineered structural wood products particularly useful in critical applications such as joists, headers, and beams where longer lengths, greater widths, and higher and predictable stress ratings may be required. The invention is also directed to a method for making the wood products. Most logs by nature are radially anisotropic, having wood of higher density and stiffness in their outer portion adjacent the bark than is found in the inner portion. The logs are machined to segregate the denser, stiffer outer wood. A first generally rectangular component is formed from the less dense inner wood. Second generally rectangular components are formed from the stiffer outer wood. Second components are adhesively bonded to at least one edge of the first component, more usually to opposite edges. The stiffer wood is thus specifically placed where it will contribute most effectively to the properties of the product. The product is analogous to an I-beam in which the lower density first component serves as the web and the higher density second component as the flange portion The products can be handled in use in identical fashion to solid sawn lumber. They are characterized by much less variation in their stiffness than solid sawn visually or machine graded products and can be made in a wide range of width, thickness, and length.

摘要： A wooden frame for window or door leaves is composed of frame pieces, each one of which comprising a first part facing outwards in a wall opening and a second part facing inwards. The outer, first part of the individual frame piece is delimited by two surfaces converging outwardly and at an acute angle relative to each other, said surfaces emanating from dividing cuts made in an initial log, said cuts extending radially from the area of the center of the log. In that way, the annual rings in the wood material are orientated in such a way that imagined tangents to individual annual rings cut through said surfaces substantially perpendicularly to the planes of the surfaces and older annual rings being situated closest to the free, narrow edge of the part.

摘要： A method and apparatus for the efficient production of heart wood centered small dimensioned, square timber comprising a log feed system for the storage and dispensing of individual logs to the production facility; a log centering system wherein the log is centrally aligned with multiple saw blades and clamped into position; a log transport system comprising a movable carriage which transports the clamped log through the blades; and a separation system wherein the finished timber is separated from the side cuts and positioned ready for easy stacking. The log is first cut longitudinally and perpendicularly along two sides. A rotating means located within the centering system turns the log onto one of its two sawn sides and the log is again passed through the blades and cut longitudinally and perpendicularly, thus forming a timber with a square cross section and the heart wood centered therein.

摘要： A process for producing beams of square cross-section from tree boles or the like is characterized in that plano-convex slabs are severed in parallel to the hart zone of the boles. An apparatus for performing the process is characterized in that the boles (2) are supported by height-adjustable supports (9, 10) in such a way that the heart zone (8) is congruent with the preferably horizontal feeding direction of the bole (2). Thereby, the thus-produced square beam (7) is defined by planes parallel to the heart zone.

摘要： An edger for use with a conventional sawmill, including upper and lower chippers or cutters for forming the upper and lower edges of a board to be removed from a log, mechanical or optical sizers for automatically determining the location of the upper and lower edges of the board, and a control mechanism, responsive to the sizers, for positioning the cutters. The cutters have horizontal or vertical motors with associated blades, and the motors are mounted on carriages which ride up and down on a mast, positioned by a hydraulic cylinder. Mechanical sizing wheels are mounted on separate carriages, and the wheels are urged to contact the log's surface to determine extreme points of narrowness thereof. The extreme motion points of the sizing wheels are recorded by frictionally secured pistons which are sensed by metallic sensors which are input to the control mechanism. An electric eye causes the sizing wheels to move toward and away from the log. During each forward pass of the log toward the saw, the cutters cut the top and bottom edges off the board that the saw will remove from the log, while the sizers profile the log or locate the minimum width points to be used during the succeeding pass of the log to position the cutters. The single channel or double "H-beam" mast has machined sidewalls to which flanges are attached upon which the carriages slide vertically. Linear slide bearings can also attach the carriages to the mast.
