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.
