Abstract: The present invention relates to a method of manufacturing a part, such as a preform, for a wind turbine blade. One or more channel members (72) are fastened to the mould surface of a preform mould, and a fibre material (85) and a binding agent is arranged on the mould surface (87). The fibre material, the binding agent and the one or more channel members are covered with a vacuum bag, and negative pressure is applied to the fibre material and binding agent via the one or more channel members for consolidating the preform. Each of the channel members (72) comprises a plurality of slits (77) extending between its inner surface and its outer surface, the slits having an orientation that is substantially transverse to the longitudinal axis of the channel member.

Abstract: A gripping device (76) is provided for lifting a preform for a wind turbine blade from a preform mould (71). The gripping device (76) comprises a base frame (62), a plurality of arms (78) slidably mounted on the base frame (62), each arm (78) having a proximal end and a distal end, a plurality of gripping members (86) for gripping a top surface (75) of the preform. The vertical position of one or more arms (78) of the gripping device (76) relative to the base frame (62) may change when lowering the gripping device (76) towards a preform to reflect the top surface (75) of the perform.

Abstract: The present invention relates to a moulding assembly (100) for manufacturing a shell part of a wind turbine blade, and to methods of manufacturing a shell part of a wind turbine blade using the moulding assembly. The moulding assembly (100) comprises a blade mould (96) with a moulding cavity (97), a gripping device (76) for releasably engaging a preform (98) for the shell part, and a lifting device (102). A tensionable member (112) is attached to the blade mould (96), and a tensioning unit coupled to the tensionable member is used for creating and maintaining tension on the tensionable member while arranging an engaged preform within the moulding cavity.

Abstract: Disclosed are processes and systems for degassing liquid resin. Resin is provided at a resin inlet and pumped into a first duct using a resin pump to achieve a first absolute pressure of at least 1.6 bar in the first duct; the resin pump and/or a flow control valve are configured to achieve a first pressure drop across the flow control valve of at least 1.5 bar; a second duct communicates the resin from the flow control valve to a storage tank; a gas evacuation system maintains a pressure in the storage tank below 100 mbar at least partly concurrently with pumping resin into the first duct.
