Patent number: 11691352Abstract: A post-moulding station is described which is used in the manufacturing of a wind turbine blade. 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.Type: GrantFiled: August 14, 2018Date of Patent: July 4, 2023Assignee: LM WP PATENT HOLDING A/SInventor: Bernard Willem De Waal Malefijt

Publication number: 20170274563Abstract: A system and method for the manufacture of wind turbine blade moulds and wind turbine blade mould plugs is described. The method comprises dividing a blade mould geometry (70) or plug geometry into separate geometrical slices or segments. The separate slices can then be used to control a cutting of blank elements (78) to form separate cut surfaces (82). The cut surfaces are used to form a consolidated wind turbine mould surface.Type: ApplicationFiled: August 18, 2015Publication date: September 28, 2017Inventors: Bernard Willem DE WAAL MALEFIJT, Ulrik WOLF, Daniel Schlichting KIRKEGAARD
