Abstract: Rotor blade for a wind power plant. The rotor blade includes a plurality of curved laminated wooden modules attached to each other, where each curved laminated wooden module includes a plurality of laminated veneer lumber boards. Each curved laminated wooden module is curved in at least one direction, where each laminated veneer lumber board includes a first set of veneer plies, where the first set of veneer plies includes a plurality of veneer plies and where the wood grain is directed in a first direction, and a second set of veneer plies, where the second set of veneer plies includes a single veneer ply or several veneer plies arranged adjacent each other and where the direction of wood grain differs from the first direction. Beneficially, the rotor blade including curved laminated wooden modules can be obtained in an easy and cost-effective way. The rotor blade is further environmental friendly.

Abstract: A 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 includes 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 including one or two plies with the wood grain directed to be 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, and gluing and pressing the plies to each other to form the laminated veneer lumber board.
