<p>The plate (1) has a middle layer (2) arranged between external layers (3, 4) using laserable adhesive i.e. urea glue. The middle layer is formed by a core e.g. medium-density fiberboard wood fiber core. Each external layer comprises the plies (5-8) made of wood veneer. A pair of grid-like structure reinforcements is arranged between respective pair of plies. A wood-glue compatible sizing agent is applied onto the reinforcements. Thickness of the middle layer constitutes 30 to 99 percentage of overall thickness of the plate. The reinforcements are made of plastic, metal or glass fiber fabric.</p> |
