Patent number: 6701984Abstract: The process is used for making individual wood boards (52) from a plurality of wood pieces (10). In this process, wood pieces (10) of similar length and are joined side by side so as to form a panel (30). The panel (30) is then cut in a longitudinal direction with reference to the wood pieces (10) into panel sections (40) having a similar width. These panel sections (40) are jointed end to end to form a continuous wood board (50), which is then cut into individual wood boards (52). This process allows to manufacture wood boards (52) with a high degree of structural integrity and dimensional stability. It also allows to efficiently use small wood pieces (10) that could have been considered otherwise waste or low-grade materials, thereby increasing the yield of the sawmill.Type: GrantFiled: December 14, 2000Date of Patent: March 9, 2004Assignee: 9069-0470 Quebec Inc.Inventors: Ghislain Lamontagne, Oliver Lamontagne

Patent number: 4941521Abstract: 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.Type: GrantFiled: October 3, 1989Date of Patent: July 17, 1990Assignee: MacMillan Bloedel LimitedInventors: Alfred W.

Patent number: 4938265Abstract: 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.Type: GrantFiled: November 10, 1987Date of Patent: July 3, 1990Assignee: Morgan CorporationInventor: Elton E.

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).Type: GrantFiled: September 12, 1988Date of Patent: August 15, 1989Assignee: Wadkin plcInventor: Thomas Robson

Patent number: 4800938Abstract: 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.Type: GrantFiled: November 10, 1987Date of Patent: January 31, 1989Inventor: Malcolm M.

Patent number: 4294647Abstract: Apparatus is described for continuously producing finger jointed lumber from individual elongated boards. Each board includes opposed end faces with elongated parallel fingers that will mate with complementary fingers of a following board to form end-jointed lumber. A reciprocating ram engages one end of successive individual boards, pushing the board longitudinally along a path to a confining box. The ram retracts to engage a successive board along its end face to push it longitudinally into engagement with the board held by the confining box. The fingers of the engaging board ends mate within the confining box and are pressed together to complete a joint. The ram includes a ram face that is complementary to the finger configuration of the board ends to mate intimately with the board end. The ram face may be heated to apply heat to the successive board ends for glue curing purposes.Type: GrantFiled: May 20, 1980Date of Patent: October 13, 1981Inventor: Melvin D. Strickler

Patent number: 4248280Abstract: Method and means, including a trim saw structure, for assembling finger jointing lumber by an impression finger joining process wherein the ends of two pieces of lumber are placed in spaced apart position and held securely by clamps. A movable section of the machine trims and shapes the ends of the lumber into fingers which are then engaged by a hot die for further impression forming and heating of the fingers. The die moves out of position and a movable applicator applies glue to the outer half of the matching ends of the lumber. The ends are then pressed together and the joined pieces of lumber are advanced away from the work station. The process is a continuous such that incoming random lengths of lumber are joined to form a continuous outgoing length of lumber for cutting into desired lengths. One or more lines of lumber may be advanced through the finger jointing work station during a machine cycle.Type: GrantFiled: December 7, 1978Date of Patent: February 3, 1981Inventor: Keith A. Taylor
