摘要： The invention relates to a multi-ply wood product. The supply of wood suited e.g. for the production of plywood has considerably decreased. Consequently, attempts have been made to compensate the deterioration in the quality of the surface finish and in other wood qualities e.g. by means of various coating methods, with varying success. The most important problem has been the insufficient adhesion between the coating and the wood. For the elimination of these problems, a multi-ply wood product has been developed in which at least one layer is formed by a crude fiber ply blank comprising haphazardly oriented fiber material as well as bonding agents, additives and filler materials. A single hot-pressing step in connection with the production of the multi-ply wood product forms this blank into homogeneous ply (14) which, by virtue of the partial splitting of the fiber structure and the resulting reorientation, which take place during the hot-pressing, fills the irregularities in the surface of an adjacent wood layer (1) and forms a tight synthetic ply of accurate dimensions.
