Abstract

A method of making a wind turbine blade in a blade mould is described. The wind turbine blade comprises a plurality of elongate reinforcing structures each comprising a stack of strips of fibre-reinforced polymeric material, and the method comprises: stacking strips of fibre-reinforced polymeric material to form a plurality of stacks (40), each defining a longitudinal axis; aligning the stacks relative to one another in an alignment zone outside the blade mould; supporting the stacks to maintain their relative alignment; transferring the plurality of stacks into the blade mould simultaneously while maintaining the relative alignment of stacks as the stacks are transferred; and integrating the stacks with other blade materials forming the blade in the blade mould. An apparatus for use in the method is also described.
