Multiply wood product having haphazard oriented fibres between the crude fiber ply blank and an adjacent wood layer

Abstract From the Canadian patent

The invention relates to a multiply 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 multiply wood product has been developed in which at least one layer is formed by a crude fibre ply blank comprising haphazardly oriented fibre material as well as bonding agents additives and, filler materials.
