Abstract: Rotor blade (1) for a wind power plant comprising a plurality of curved laminated wooden modules (2, 3, 4, 5) attached to each other, where each curved laminated wooden module (2, 3, 4, 5) comprises a plurality of laminated veneer lumber boards(11), where each curved laminated wooden module (2, 3, 4, 5) is curved in at least one direction, where each laminated veneer lumber board(11) comprises a first set of veneer plies (19), where the first set of veneer plies comprises a plurality of veneer plies (12) and where the wood grain is directed in a first direction, and a second set of veneer plies (22), where the second set of veneer plies comprises a single veneer ply or several veneer plies (12) arranged adjacent each other and where the direction of wood grain differs from the first direction. The advantage of the invention is that a rotor blade comprising curved laminated wooden modules can be obtained in an easy and cost-effective way. The rotor blade is further environmental friendly.

Abstract: Method for producing a laminated veneer lumber board adapted to be used for curved modules in which a plurality of laminated veneer lumber boards are laminated to each other to form a curved laminated wood module, where the method comprises the steps of; cutting a plurality of veneer plies, placing a first part of a first set of plies in a mould with the wood grain directed in a first direction, placing a second set of plies comprising one or two plies with the wood grain directed that is perpendicular to the first direction on the first part, placing a second part of the first set of plies with the wood grain directed in the first direction on the second set of plies, gluing and pressing the plies to each other to form the laminated veneer lumber board. The advantage of the invention is that a laminated veneer lumber board adapted for curved modules is provided.
