Abstract
A method of making a prefabricated root section (26) for a wind turbine blade (10) is described. The method comprises: providing a male mould (28) extending longitudinally in a spanwise direction between an inboard end (30) and an outboard end (32) and extending transversely in a chordwise direction between a leading edge (34) and a trailing edge (36), the male mould (28) defining a male mould surface (38) of convex curvature in the chordwise direction; providing a root plate (48) having one or more root inserts (50) projecting therefrom, the or each root insert (50) being arranged along an arcuate path; arranging one or more inner fibrous layers (40) on the male mould surface (38); arranging the root plate (48) at the inboard end (30), of the male mould (28) such that the or each root insert (50) overlays an inner fibrous layer at the root end of the mould (28). The method further comprises arranging one or more outer fibrous layers on top of the inner fibrous layers (40) and on top of the or each root insert (50), providing resin to the fibrous layers (40) and to the or each root insert (50) and curing the resin to form a prefabricated root section (26) for subsequent use in the manufacture of a wind turbine blade (10). Curing the resin to form the prefabricated root section (26) is conducted before removing the prefabricated root section (26) from the male mould (28).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
