Abstract (en)
[origin: EP0072296A2] The method for manufacturing is characterised in that, after forming the outline of the wheel by press-stamping a flat disc (1), the finishing of the rim (2) of the wheel is then carried out by plastic flow of the metal in the cavities of an appropriate mould and then the rim, on which the tyre is mounted, is obtained by slitting, deep-drawing and magneto-forming. <IMAGE>
