Abstract: A composite siding and planking board having an appearance similar to a natural solid wood product and method of manufacture employing a base layer formed from an engineered wood product, a resin layer, a veneer layer and a filler strip wherein the resin layer is firmly bonded to the base layer and the resin layer is firmly bonded to the veneer layer such that the veneer layer, the resin layer and the base layer form a solid board that has a top edge and a bottom edge and where the filler strip is firmly attached near the bottom edge of the board so that the filler strip is configured to include a top edge receiving area such that the top edge of an identical composite board may be inserted into the top edge receiving area.

Abstract: A method for coating laminate and composite wood products with a polymer coating. The method includes providing a wood substrate consisting of an engineered or composite wood product, applying a flowable but thixotropic polymer coating material to the surface of the substrate, distributing the polymer coating material evenly across the surface of the wood substrate to create a continuous smooth surface, and allowing the polymer coating material to bond to the surface of the wood substrate to form a hard smooth surface over the wood substrate surface.

Abstract: A technique for forming a contoured axially extending engineered moulding that has at least one axially extending exposed surface. The technique includes providing an elongated outer wood section. A substrate having at least one axially extending side is provided. The wood section is adhered to the axially extending side. The wood section is contoured uniformly in an axial direction to form the exposed surface. A preferred embodiment uses a reengineered rip saw to contour the piece of wood. It is also assumed that multiple moldings can be machined by the reengineered rip saw simultaneously. The simultaneous machining by the reengineered rip saw also permits simultaneous measurements and simultaneous cross cutting and dado cutting of the moldings.

Abstract: A method of making composite strips for mouldings, frames and the like, including the steps of providing a first elongate panel of a first material and a second elongate panel of a second material, laminating the first and second panels onto one another to provide a laminated panel, making a plurality of parallel cuts or slots in the second panel, adhering a filler strip to the first and second panels in each of the cuts, and gang sawing the laminated panel into composite strips by cutting the laminated panel at each of the filler strips. The filler strips may be formed as single pieces and may be formed as a pair of pieces not joined together. A composite panel having first and second elongate panels of different materials laminated together, with a plurality of parallel cuts in the second panel, and with filler strips in the cuts and adhered to the first and second panels. Several alternative embodiments are also disclosed.

Abstract: A method of fabrication with the formation of a receiving panel which defines a plurality of spaced-apart parallel plows extending longitudinally. The panel has an open surface along which the plows are exposed and an opposing surface from which the plows are not accessible. The plows may be formed by adhering substrates to a separate veneer layer to define the plows between the substrates. It is preferable that the veneer layer be formed of wood, but the substrates can be formed of a less expensive material, such as composite material. Once the receiving panel has been fabricated, it is bowed to form an arc about an axis parallel to the plows. This can be done by passing the panel, carried by a belt, between two rollers that are configured to define between them a profile corresponding to the arc of the panel. While the panel is in this bowed condition, strips, made of wood, are inserted in the plows. The strips can be formed by opposing laminations that are not adhered to each other.

Abstract: A method of making composite strips of millwork components, including the steps of providing a plurality of elongate strips of wood and a support sheet, adhering the strips of wood together in parallel with each other and to the support sheet to form an elongate composite sheet, and machining the composite sheet to a desired contour to form a molding strip. The method may also include the step of removing the support sheet after the machining step by machine, or by peeling, or otherwise as desired. Typically the strips of wood are of differing widths and heights. A composite molding strip is also disclosed.

Abstract: A method of making a base for a split jamb for a door frame opening, with the base having a groove for receiving the tongue of a slide of a split jamb, including the steps of providing an elongate panel, making a plurality of parallel cuts in the panel, with the cuts not cutting through the panel, the cuts including a plurality of pairs of slots, with the slots of a pair spaced from each other leaving panel material between the slots of each pair, adhering a stop strip over each pair of slots covering the slots of the pair, and gang sawing the panel into jamb base strips by cutting between the slots of each pair of slots to remove the panel material between the slots providing individual jamb base strips. The method wherein the step of making parallel cuts includes making a plurality of notches spaced from each other by the pairs of slots, and wherein the step of gang sawing includes cutting through the panel at each of the notches.

Abstract: The present invention is embodied in shipboard apparatus for heat-treating pieces of wood or wood products, such as logs, lumber wood chips or wood strands with steam or hot water to kill any plant pests present in the wood or wood products. The pieces are loaded into a hold of a ship. The ship is equipped with a heater or boiler for producing steam or hot water, and piping and associated equipment such as nozzles for introducing the steam or hot water into the hold. In some embodiments, the ship is also equipped with piping for recycling the spent steam or water back to the heater or boiler for producing the steam or hot water. As the steam or hot water is introduced into the hold, the wood pieces are contacted with the steam or hot water to raise the temperature of the pieces to a sufficient level for a sufficient period of time to kill any plant pests that might be present.

Abstract: A millwork building construction member of rabbeted construction such as a doorjamb which includes a core to which a thin bendable exterior skin is bonded. The core is a non-lumber wood material such as composition board that has been folded after V-shaped grooves have been cut and the skin has been affixed. The skin is thus wrapped around the folded core to form the exterior surface of the member, while a cavity is defined that extends longitudinally through the core. The cavity can be filled for added strength. The skin may be selected for its decorative or fire-retardant properties.
