Abstract
A method of trimming a production flange (52) from a wind turbine blade (10) during manufacture of the wind turbine blade (10). The method comprises mounting a self-propelled flange trimming apparatus (60) on the production flange (52) and using a drive system (64, 66) of the apparatus (60) to propel the apparatus (60) along the production flange (52). A directional control system controls the direction of the apparatus (60) and a cutting tool (81) cuts through the production flange (52) as the apparatus (60) travels along the production flange (52). Also, a self-propelled production flange trimming apparatus (60) comprising a carriage (61) with a drive member (64, 66), a directional control system, and a cutting tool (81) attached to the carriage (61). A system comprising a wind turbine blade moulding (50) and a trimming apparatus (60) mounted on the production flange (52) of the moulding (50).
