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: 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.
