Abstract

In order to make a rotor blade provided with ridges where the ridges lie close to each other and have a mainly circular direction with the centre in the rotor axis and where the ridges have a form tapering outward, characterized by the fact that the ridges are formed by a cylinder provided with grooves under strong pressure and under rotation pressing against the rotor blade so that its surface layer flows and, after the cylinder has passed the formed ridges, they remain. Procedure according to Claim 1, characterized by the fact that, at the same time as a cylinder forms one surface of the blade through pressure against its surface, another cylinder forms the opposite side of the blade through pressure directed roughly opposite the direction of pressure of the first cylinder.
