摘要：Method and machine for making rotational bodies by plastic deformation with adiameter varying lengthwise. Method wherein, upon rotating the blank, a local pressure isexerted with a progressive increase of force involved at start so as to reach a sufficientlimit. For implementing such method, the blank is treated between two pressure areaswhich have an intersection by displacing the areas relatively between each other, whilethe blank is displaced in relation to the intersection point of the two areas and thevariation of the diameter of the object to be manufactured.
