The present invention relates to a system for repairing a plywood panel, the system comprising: at least one detection device for scanning the plywood panel; at least one repairing device for performing a repair operation for the plywood panel; a conveyor device for conveying the plywood panel; and a control device for generating at least one control signal to the conveyor device to halt the plywood panel in the system for performing a scanning operation of the plywood panel with the at least one detection device and to halt the plywood panel for performing a repairing operation with the at least one repairing device on the basis of information obtained with the detection device. Some aspects of the invention relate to a method for performing the repair operation.

A multifunction plate of wood repair apparatus includes a feeding device for moving raw plates of wood; a cutting and gluing device disposed downstream of the feeding device for cutting front and rear ends of each plate of wood and joining adjacent plates of wood together as a unit of predetermined size by gluing; a repairing device disposed downstream of the cutting and gluing device for identifying locations of damaged areas of the plates of wood, the repairing device including an upper mold, a female mold under the upper mold, a chips exiting device under the female mold, a lower mold under the chips exiting device, and a drive device under the lower mold and operatively connected to both the upper mold and the lower mold; and a collecting device disposed downstream of the repairing device for collecting the repaired plates of wood.

A building panel with a surface layer including a wood veneer, a wood fibre based core and a sub-layer between the surface layer and the core. The sub-layer includes wood fibres and a binder. The surface layer has surface portions including material from the sub-layer. The surface portions including material from the sub-layer extend into the wood veneer.

A method of producing a veneered element, 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.

A veneer cutting and sorting apparatus is disclosed. The apparatus includes a revolvable knife blade having a cutting edge and a revolvable knife edge receiver having a cutting edge receiving surface. The knife blade cuts a veneer sheet as peeled from a peeler block by a veneer lathe at a previously detected boundary between defective veneer portion and product veneer sheet on the cutting edge receiving surface then revolving at the same peripheral speed as the cutting edge of the knife blade. Cut-off defective portion is allowed to drop off by its own weight.
