Method for producing a wood structure with a decorational pattern, a device for patterning a piece of wood and a decorational wood structure

A method for mechanically producing a wood structure with a decorational pattern, the wood structure having a plurality of pieces of wood, each piece having two edges, the method comprising the steps of:

• dividing the decorational pattern of the wood structure into partial patterns using software means,
• forming movement tracks of at least one milling cutter of a processing head of a device to process the wood structure based on the partial patterns using the software means,
• processing partial patterns onto a working face of the plurality of pieces of the wood structure by moving, with a processing movement, the at least one milling cutter of a processing head of a device for patterning transversely to each piece of wood with an axis of rotation of the milling cutter at an inclined angle relative to a plane of said working face forming grooves of each partial pattern, each of the grooves having two planes set at an angle relative to each other and a changing depth in a transverse direction of the groove,
• forming several grooves successively onto the working face of said plurality of pieces of wood with one said processing movement, each processing movement starting or ending at the edge of the piece of wood, and
• forming the wood structure by placing said plurality of pieces of wood side by side wherein the partial patterns together form the decorational pattern of the wood structure.
