Abstract (en)
[origin: WO2009101250A1] The invention relates to a method for manufacturing a flange ring (9) of a wind power plant having an L-shaped cross-section, in which method the flange ring (9) is manufactured by bending from a straight rod (1) with a right-angled cross-section first a ring blank (8) and then machining the cross-section of the ring blank (8) into the L shape. In the invention, before the rod (1) is bent into the ring blank (8), on one surface of the straight rod (1), a groove (2) extending in the longitudinal direction of the rod is formed to provide an essentially U-shaped cross-section for the rod (1).
