The invention represents a substantial simplification and improvement the existing production methods. It enables the production of grain veneers, as it could not be achieved by the known methods. -The real ones with many Types of wood on the cut surface of the veneer visible indentations, such as eyes, Rings, crater-like structures and spots of a similar kind are mostly the result of with cut wild shoots, tubers, growths and the like that cut right through the wood masses grow, e.g. B. in bird's eye maple, in Thuya and others.
