Abstract
A method of producing a rotor component or a stator component includes the steps of providing a disc-shaped element with a plurality of radially projecting and circumferentially spaced blades, an intermediate ring with an inner surface adapted for contacting tips of the blades, and an external ring with an inner surface adapted for contacting an outer surface of the intermediate ring, moving the intermediate ring co-axially in relation to the disc-shaped element to an operative position in which it is located radially outside the blades, and moving the external ring co-axially in relation to the intermediate ring to an operative position in which it is located radially outside the intermediate ring.
