Abstract: A manufacturing method for a wind turbine blade is described which utilizes a post-moulding station in the manufacturing process. A blade shell forming part of a wind turbine blade is initially moulded in a blade mould, the blade shell subsequently transferred to a post-moulding station which allows for various post-moulding operations to be carried out on the blade shell away from the mould, thereby increasing the productivity of the blade mould in the manufacturing process. The post-moulding station may be operable to perform the closing of first and second blade shells to form a wind turbine blade, and may be formed from an adjustable structure which can provide relatively easy access to the contained blade shell for working thereon. Accordingly, the manufacturing equipment may be of reduced cost, combined with an increase in the overall productivity of the manufacturing system.
