Abstract:
The present invention relates to a method of manufacturing a blade for a wind turbine, wherein the blade is made in one or more moulds; and wherein the blade has integrally moulded root bushings in the root of the blade for direct or indirect attachment to a hub in a wind turbine. The novel aspect of the invention is that the root bushings (203) in the root (201) of the blade are leveled by shortening of at least one of the root bushings prior to the blade being removed from a supporting mould (205). The invention further relates to a blade made in accordance with the method and a leveling unit (207) for leveling the root of the blade, wherein the leveling unit comprises means for mounting on a mould.
