Claim:
A method of manufacturing a wind turbine blade having a suction side and a pressure side and a spar disposed between the suction side and the pressure side, the method comprising: prior to assembly, providing at least two caps, each cap forming an intermediate portion between two end portions, where the end portions extend transverse to the intermediate portion and form a cap joint surface portion along a longitudinal extending edge of the end portion and the intermediate portion forms an outer surface portion of the spar, prior to assembly, providing at least two webs, each web being provided with web joint surface portions along opposite and longitudinally extending edges, assembling the spar by arranging the caps relative to each other so that the end portions of one cap extend from the intermediate portion towards the end portion of another cap; connecting the joint surface portions of the caps with the joint surface portions of the webs to form a tubular configuration of the spar; and orienting the spar relative to the wind turbine blade such that the intermediate portion of at least one cap confronts or forms part of the suction side of the wind turbine blade.
