Abstract
Abstract This specification discloses to a plywood overlaid with a decorative paper and the method of manufacturing the same. An adhesive bonds the paper to the plywood. The decorative paper is characterized by being very thin and by having a simulated wood grain pattern. The overlaid paper is coated with a transparent resin coat. The coat is embossed with wood-grain simulating pattern. The coat also includes elongated longitudinal parallel channels wider than the embossings and reaching the depth of the plywood. The channels are colored differently from the color of the wood grain pattern.

Claim 9
Dependent Claim
212 words
The process for the manufacture of a plywood overlaid with a decorative overlay paper, which comprises the steps of uniformly coating the surface of a base plywood with an adhesive which fills the holes and recesses in said surface; partially drying the adhesive coated on said surface; with said adhesive, bonding to said surface a thin decorative overlay paper having a dry weight within the range of 23 to 27 grams per square meter and having the color print of a wood grain pattern; trimming the edges of said overlay paper; coating a transparent coat on said overlay paper; drying the transparent coat completely; press-forming on the layer of said transparent coat a number of transversely spaced-apart, fine-grained grooves extending intermittently in the direction of the wood grain pattern on said overlaid paper; forming a plurality of elongated, transversely spaced, recesses wider than the grooves and extending longitudinally of said base plywood; forming the recesses to such depth as to reach the base plywood; and coating the surfaces of said recesses with paint of a different color from said overlaid paper, whereby the wood grain pattern on said overlaid paper can be embossedly viewed through the layer of said transparent coat, thus giving an appearance of a real wood to the plywood.
