  • Surface finishing of rotor blades for wind turbine
    Patent number: 8567058
    Abstract: The present invention relates to a method for surface treatment of a wind turbine rotor blade (1) comprising a leading edge and a trailing edge separating substantially opposing first and second surfaces of said rotor blade. The method comprises the steps of providing a wind turbine rotor blade, supporting said rotor blade at least at a root end and at a distal position along a longitudinal axis of the rotor blade and providing moveably arranged first and second surface treatment devices (24, 25) adapted to provide surface treatment of the first and second surfaces of the rotor blade, respectively, wherein the first and second surface treatment devices are moved in opposite directions and towards the leading and trailing edges, respectively, during surface treatment of the first and second surfaces of the rotor blade.
