Abstract: The felling and bunching head for severing and grouping trees has a shear or saw or the like for severing trees, and an accumulation area for accumulating severed trees, extending rearwardly from the shear or saw, substantially outwardly and away from a centerline of said head. Taker and tucker arms are pivotally mounted to pivot towards and away from the accumulation area. The taker and tucker arms are mounted via pivotal connections located substantially outwardly from the shear or saw on the opposite side of the centerline from the accumulation area, on substantially the same axis. The taker and tucker arms have generally similar geometries facing the accumulation area, as viewed from above, thereby presenting generally similar geometries to trees in the accumulation area, thereby minimizing jostling of the trees when they are alternately held in the accumulation area by the taker arm and by the tucker arm.

Abstract: A tenonizer apparatus has a motor and a circular cutting blade assembly mounted on a pivotable platform. A radius shoulder support shaft is pivotably mounted perpendicular to the circular cutting blade. The operator pushes and rotates the log along the shafts to create the tenon. Only one tenon can be cut at a time. A minimal set up time is required to switch between tenon types. The pivotable platform allows variable length tenons to be cut. The apparatus is portable.

Abstract: A selective plurality of elongate half-logs, lumber planks which may have imperfect or damaged edges, or a combination of both, are superposed on each other and adhesively joined to form an intermediate assembly, which is then divided by one or more beam-long cuts made perpendicularly to the flat surfaces of the half-logs or planks. The resulting outer sections of the intermediate assembly, substantially mirror-images of each other, are reoriented so that the original outer edges face each other and are positioned so that a selected space remains between them. Various spacing and bracing elements are selectively chosen to connect the two outer sections and thus to form a laminated space-containing wood beam structure, on which surface-covering sheathing or coatings may be applied optionally.

As a result, it is possible to obtain high-class laminated lumber without knots on three or four sides by using natural wood with knots with a high product yield.In the method of making the laminated lumber, a plurality of prismatic wood are arranged in the transverse direction, outside pieces of the prismatic wood have no knots, inside pieces of the prismatic wood which have inside knots lengthwise are rotated such that the knots of the inside pieces of the prismatic wood are present in the transverse direction. By arranging the prismatic wood in this way, there is substantially no knots on the four sides of the laminated lumber.

Abstract: A method of resawing elongated radially sawn segments of timber so that bsawn boards are produced. Said wedges are sawn with the desired angle between the radial faces and are resawn so that the growth rings of the tree are basically parallel to the broad backsawn faces. The flared radial edges of the boards indicate the growth ring orientation and therefore the cupping tendency and the direction of bow. This enables a greater degree of consistency in the manufacturing process over conventional methods. Said backsawn boards can be used individually as conventional boards with the mentioned advantages or can be laminated together to make a range of laminates that balance or use the bowing and cupping tendency of backsawn timber.

Abstract: A method of simulating a solid wood multipanel door is disclosed. Predetermined portions of the thin sheets of wood which are typically used to construct hollow core doors are cut away. The portions are used to construct artificial door panels, which are replaced into the openings in the hollow core door from which they were cut. Molding is then placed around the artificial door panels. In an alternative embodiment, Wainscott panels may be constructed utilizing the inventive technique.

Abstract: A method for production of a trussed rafter, wherein the nail plates are affixed to timber members in conjunction with cutting of the timber members and before they are transported to an assembly station. The assembly station can be any type of a rafter jig but can also be a levelled surface, e.g., a factory floor, thereby eliminating the need for an assembly jig. The labor and force required in timber member jointing are substantially reduced, because the nail plates are already affixed to the timber members and assembly can be largely limited to affixing of upper nail plates (8). The assembly surface has a grid pattern (1) thereon, enabling the positioning of side quides (2) required for assembling. Markings indicating prefixed platings and/or nail plates positions are used to provide quality control.

Abstract: A method for preventing cracks in bamboo canes subjected to drying comprises longitudinally cutting open the bamboo cane along its entire length, allowing the cut cane to dry to a desired residual moisture content, and sealing the resulting longitudinal gap by adhesively bonding into the longitudinal gap a multi-section filler strip. The longitudinal gap may be milled out to produce desired dimensioning and shaping. The strip may also be mechanically attached to the cane by clips, screws or dowels. The cane may be optionally chemically pretreated before drying.

Special side bars are employed for grooves have greater internal dimensions than their openings. A controller also mounted on the base may be utilized to regulate the heating tape.

Abstract: There is disclosed a method for the ammonia saturation of wood to impart flexibility thereto which includes the step of sealing the surfaces of ammonia-saturated wood with a polymeric film which has limited or no permeability to either or both ammonia and water vapor. Preferably, the polymeric film is flexible so the working of the wood product by bending, twisting, embossing, molding, etc. will not destroy the film. The polymeric film should also be soluble in a selected solvent, thereby permitting its removal after the wood has been formed in a final, desired shape to permit water vapor to re-establish crosslinking of the cellulose chains and restore its natural, rigid condition.

Abstract: A system for constructing mitered corners on a table saw having a rotatable adjustable miter guide slidable in a groove on either side of a saw blade comprises a presentation device having two surfaces meeting at a fixed angle. Any error in setting the angle of the miter device is canceled by placing the presentation device between the first piece to be cut and the miter guide while cutting the first piece, then moving the miter guide to the opposite groove without resetting the miter angle and reversing the presentation device between the second piece to be cut and the miter guide. In a preferred embodiment the presentation device has an engagement mechanism for engaging the miter guide and an adjustable slide stop for determining the cut length of a piece of material.

Abstract: Improved methods of fabricating at least partially curved staircases include a first method in which preformed step structures have treads with curved slots formed in the underside of the ends which define a path for insertion of top edge segments of thin starter strips. The slots are collectively configured to laterally deflect the inserted starter strips in a manner longitudinally conforming them to at least partially curved paths of the overall stringer structures in the completed staircase. The stringers are then laterally built up and completed by securing reinforcing structures to the side surfaces of the laterally deflected strips. A second method uses preformed cooperating treads and risers themselves as a form which defines an at least partially curved path for the stringers.

Abstract: The process begins with a single board, for instance a flat grain board, of selected dimensions. The single board may be clear or not or may be cut and rejoined to remove defects. The board is then sawn in a selected manner and the resulting boards are bonded together by gluing to form a remanufactured board, in such a manner that the glue lines are substantially invisible. In one preferred embodiment, a flat grain board is rip sawn and then edge glued to form a vertical grain board of selected dimensions.

Abstract: A tambour door includes a plurality of elongated elements having front and back surfaces of rectangular transverse cross-section placed in abutting side-by-side relationship including a flexible backing material overlaying and adhesively secured to the back surfaces of the elongated elements. The front surface of the elongated elements are formed with a design which extends over a plurality of adjacent elements. A cabinet including such tambour doors includes side pockets in which the doors move on tracks when the doors are moved to the open position. When the doors are in the closed position, they are planar and extend across the opening into the cabinet. When the door is in the closed position, the interface between adjacent elements is virtually invisible because of the abutting relationship of the elements and because of their rectangular cross-sectional shape.

Abstract: A process is described for making a laminated wood product having improved strength and dimensional stability (i.e., less warping caused by temperature and/or moisture change in drying, transportation and in use). Adjacent surfaces of lumber or veneer laminae cut from a single piece of wood are arranged in units of three laminae where the center lamina is twice the thickness of each outside lamina and in such a way that the outer laminae are rotated 180 degrees about their longitudinal axes to provide mirror images of the surfaces of the center lamina. These trios are arranged in a symmetrical manner about the central plane of the laminate and then bonded together. The minimum number of laminae is three, but with increments of three additional laminae the mirror-laminate can be built up to any desirable thickness. The mirror-laminate may be used in rough form or surfaced to specific finished dimensions.

Abstract: A furniture frame part or the like is made from a first, planar laminate of wood or other material. This laminate is bent so as to form a shaped member of single curvature. The shaped member is cut into slices in a direction transverse to the generatrices of the curvature, and from these slices a second laminate is made. This second laminate is bent in a direction so as to form another curvature with generatrices extending generally transversely to the first mentioned generatrices, whereby a furniture frame part or another composite body of double curvature may be made.

Abstract: A high yield technique to convert normally-unusable round logs of balsa or other species of wood whose diameter is less than about 4 inches into large rectangular panels that are contourable.The raw logs are first peeled to expose the wood and are then cut into round pieces of a desired length. The pieces, after being kiln-dried, are stacked to form a dry assembly in which the pieces are separated from each other to define a matrix of intersticial spaces. The pieces in the assembly are then interlaminated in a mold by filling the matrix with an elastomeric plastic solution which, when cured, functions as an adhesive to provide an integrated stock block. The stock block is then divided into panels of the desired thickness, each panel being constituted by an array of round wood tiles joined together by elastomeric hinges, whereby the resultant panel is contourable and may be conformed to a curved surface.

Abstract: A reinforced veneer sheet and a method of manufacturing the reinforced veneer sheet are provided. On an imperfect veneer sheet, a plurality of closed cuts are formed in a row through the sheet across the veneer grain. Through these closed cuts, a length of cord is forced at its intermediate portions from one side of the sheet until they protrude from the other side. The cuts are formed repeatedly and the cord is also forced through the cuts repeatedly on a veneer sheet fed in one direction or cut off from a log turned on a veneer lathe.

Abstract: The method of converting logs involves cutting each log longitudinally and diametrically at right angles into equal quarter-log segments, the rearranging the quarter-logs so that the arcuate surfaces of the segments face inwardly toward each other, while their cut flat surfaces are positioned to form a rectangle in cross-section. The segments so positioned may be joined together as such, rigid foam plastic insulation may be introduced into the space remaining between the segments, or support bracing and other insulation may take the place of the rigid foam. The resultant converted logs may be used as beams, joists or bearing-wall members; devices for aligning, registering and sealing the converted logs together are provided.
