ABSTRACT:
A method for producing veneered compressed parts, wherein a carrier, an intermediate sheet of veneer and a cover sheet of veneer are glued together in a molding press as to form a unfinished molded part. The cover sheets of veneer and optionally the intermediate sheets of veneer are thoroughly dyed in an aqueous dye bath before executing the molding process and then dried while the surface of the finished molded part is lacquered. A continuous layer of a pasty, hardenable impregnating agent is applied on one side of the thoroughly dyed cover sheet of veneer and the layer of impregnating agent is substantially prehardened while preserving flexibility. The cover sheets of veneer are stabilized mechanically as well as their color fastness by the layer of impregnating agent.
