Patent ID: 8567058

Claim:
A method for surface treatment of a rotor blade for a wind turbine, the rotor blade comprising a leading edge and a trailing edge separating substantially opposing first and second surfaces of said rotor blade, the method comprising: supporting the rotor blade at least at a root end and at a distal position along a longitudinal axis of the rotor blade, wherein a supporting member at the root end is configured to prevent rotation of the rotor blade about the longitudinal axis of the rotor blade; providing a moveably arranged first surface treatment device configured to provide surface treatment of the first surface of the rotor blade; providing a moveably arranged second surface treatment device configured to provide surface treatment of the second surface of the rotor blade; and moving, via a control module, the first and second surface treatment devices in relative opposite directions during surface treatment of the first and second surfaces of the rotor blade, so that when the first surface treatment device moves toward the leading edge, the second surface treatment device moves toward the trailing edge, and vice versa.
