A method to produce a building panel, including providing a core, applying a first paper layer on a first surface of the core, wherein the first paper layer includes a resin impregnated paper, applying refined lignocellulosic fibres on the first paper layer, applying a wood veneer layer above the refined lignocellulosic fibres, applying pressure to the core, the first paper layer, the refined lignocellulosic fibres, and the wood veneer layer to form a building panel. Also, to such building panel.

A composite material and structure. The structure has a folded sheet having a rigid inner layer sandwiched between flexible outer layers. The sheet has an undulated shape with alternating summit and valley portions. Intermediate portions each extend between adjacent summit and valley portions. At least one score line extends through at least one of the flexible outer layers. The sheet is folded about the at least one score line. A method of forming a structure from a sheet having an undulated shape

A method and system for production of layered wood products employs local and independently operating robotic panel assembly cells including one or more veneer handling robots, one or more core handling robots, and one or more glue application robots to produce stacks of layered wood product panels locally near the pressing stations. Consequently, the stacks of layered wood product panels are independently built at, or near, the location of the pressing stations. This eliminates the need for traditional panel conveyors, traditional layered wood product panel assembly layup lines, and stack press delivery lines. This, in turn, eliminates thousands of moving parts and dozens of people from the layered wood product production process.

A method of producing a veneered element, the method including providing a substrate, applying a sub-layer on a surface of the substrate, applying a veneer layer on the sub-layer, and applying pressure to the veneer layer and/or the substrate, such that at least a portion of the sub-layer permeates through the veneer layer. Also, such a veneered element.
