12 Claims

1. A method of manufacturing a wind turbine blade, the method comprising:

providing a mould for a shell of the wind turbine blade, the mould extending in a longitudinal direction from a root end to a tip end;

providing a plurality of elongated root inserts;

providing a root plate with a plurality of arcuately arranged connection points;

at the connection points, connecting the root inserts to the root plate, such that the connected root inserts jointly form a contour of a portion of a root section of the wind turbine blade; and

positioning the root plate relative to the mould in order to place the contour formed by the root inserts at least partially into the mould,

wherein the method further comprises

providing a spacer having a decreasing thickness, and wherein

the connecting of the root inserts to the root plate comprises providing the spacer between the root inserts and the root plate.
