Abstract
The present invention relates to a method and a mould system (66) for manufacturing at least two preforms for moulding a wind turbine blade. The preforms include at least one preform of a first shape and at least one preform of a second shape. The preform mould structure (68) has a moulding surface (70) of variable shape such that the shape of the moulding surface (70) can be varied at least between a first and a second configuration by using actuators.
