Abstract: A process for making a laminated wood product includes sawing or sanding opposite faces of offcut wood strips, to prepare these faces for glueing with the strips in quartersawn orientation. The strips are also prepared by sanding or planing substantially parallel to the top and/or bottom surfaces of the strips. The strips are glued end-to-end and side-by-side to form a laminated plank having the strips in quartersawn orientation. The plank is finished to form a laminated quartersawn strip product which may be used for flooring, paneling, millwork or other purposes.

Abstract: There is provided a new and useful wooden structural member comprising a pair of elongated flanges each having a surface and a longitudinally extending groove in the surface, the groove having a bottom and tapering from the surface to the bottom; and a web disposed between the flanges and having first and second tapered longitudinal edges, the edges secured within respective ones of the grooves, each edge having a longitudinally extending central kerf therein; and wherein, prior to the insertion of said edges into said grooves, the thickness of each tapered edge at any given distance from its extremity is greater than the width of the respective groove at an equal distance from the bottom. A method for the production of the member is also provided.

Abstract: Finger jointed lumber is produced from discrete green lumber pieces each formed with a first set of fingers on one end and a second set of fingers at the other end. The first set of fingers is dried by rapidly applying heat substantially solely through the first set of fingers in a first drying station. The second set of fingers is then rapidly dried in a second drying station. A thermo-setting adhesive is applied to the second set of fingers of each lumber piece while still hot and the second set of fingers on one piece and the first fingers on an adjacent lumber piece are mated and crowded together to form a joint. The adhesive is significantly cured by residual heat in the mating ends before significant moisture migrates back to the fingers from the bodies of the mating lumber pieces and interferes with the curing of the adhesive.

Abstract: A method of preparing truck floor boards of a desired standard length from floor boards having differing, initial standard lengths. For the case wherein the desired standard length is less than initial standard length, one may begin with severing, by saw-cutting, from a board having at least one initial standard length, as many desired length-boards as are available; this leaves a remainder board. One may also begin with such a remainder board, as an end product of a previous execution of the method, or of a cycle of the method. A finger joint profile is cut in the trailing end surface of the remainder board, and a mating finger joint profile is cut into the leading end surface of an initial-standard-length board. By gluing, the finger jointing is completed, and from the resultant composite board, severed out by saw-cut are as many desired length boards as are available. This may leave a new remainder board of sufficient length to warrant its inclusion in a new cycle of the method.

Preferred embodiments of the pipe-shaped body are cut from a pipe-shaped blank so as to form one or more pairs of similar pieces of furniture, the cutting line between said pair or pairs of furniture following a symmetrical line to give optimum utilization of the pipe-shaped material. The invention also relates to the use of such pipe-shaped bodies as combined sculptures and furnitures.

Abstract: The machine is suitable for working wood, materials derived from wood, etc. A rotary cutter (10) is movable past tables (12, 14, 16) for supporting workpieces. The cutter (10) comprises a number of cutting discs set coaxially and separated by spacers. On each table (12, 14, 16) a workpiece can be set at a different level. Movement of the cutter along the ends of the workpieces on a single pass can cut a different joint in each workpiece. The thickness and diameter respectively of the cutting discs determine the width and depth of the slots cut in the workpieces for the formation of joints. The thickness of the spacers determines the spacing of the slots, not only in an individual workpiece but also on a number of workpieces set on the various tables (12, 14, 16).

Abstract: The method of the present invention comprises scanning a piece of lumber proximate its end to determine which side of its longitudinal center line its fibers are oriented toward. The piece of lumber then is oriented such that the tangent of the cutting circle of a rotary cutter, which is used to machine finger joints in its end, is offset from the fiber direction by at least 90.degree.. Finger joints then are machined in the end of the piece of lumber by the cutter. The apparatus includes a conveyor which transports a plurality of pieces of lumber normal to their longitudinal axes. A scanner, which determines the fiber direction of each piece of lumber, transmits this information along with the location of the piece of lumber on the conveyor to a microprocessor. An orienter then is annunciated by the microprocessor to rotate those pieces of lumber having fiber direction which is oriented improperly before they are fed through a finger jointer.

Abstract: A method for manufacturing an elongated, box-like structural component comprising two mutually opposing side-members (1, 2) which define a cavity therebetween. The mutually opposing surfaces of the side-members present longitudinally extending grooves into which projections on distance pieces (3) located between the members engage. In the process of manufacturing the structural component pairs of boards or the like are advanced in spaced relationship in the longitudinal direction of the boards into a receiving station (7) with the grooved inner surfaces of the boards facing one another, the distance pieces (3) being placing between the boards as they enter the station (7). As the boards leave the station, they are pressed towards one another in a manner to bring the projections on the distance pieces (3) into engagement with the grooves on the inwardly facing surfaces of the boards.

Abstract: A compound lumber slab is formed from several pieces of lumber which are edge-glued together using finger joints. The fingers have the shape in cross section of truncated triangles. These fingers, and their mating grooves, are alternately disposed along the edges of the lumber so that a saw cutting a panel from the slab will cut through the flat top of a truncated triangle, thereby producing glue lines parallel to the panel edges on the resulting panel surfaces. The truncated triangles are shaped and dimensioned to optimize the structural integrity of the resulting panels. The mating fingers and grooves may have a noninterfering fit to produce closed glue lines on the finished panel surfaces.

The strip or plank wood materials are provided in various lengths and various predetermined widths so that the random width and length strip or plank materials can be fitted together to provide a most unexpected and pleasing appearance wherein each adjacent strip or plank member is precisely fitted together and adjacent surface portions are substantially flush, or in contact.

Abstract: In the manufacturing of wood poles a number of sections are glued together along abutting side surfaces (7, 8) so that a tubular pole (19) with a central cavity is formed. The side surfaces (7, 8) which have been provided with glue are brought into intimate contact with each other so as to give a tube (19). Sealing covers (20, 21) of the lika are placed at both ends of the tube so that these are sealed, whereafter air is pumped out from the central cavity (23) through one or both of the said covers so as to give a vacuum in the cavity in comparison with the external pressure, whereby the contact pressure between the abutting side surfaces increases. The vacuum is maintained until the glued joints (31) have been fixed.
