Abstract
[0033] Two identical annular blanks (20, 30), each having a flat side surface (27, 37), are arranged side to side with the lateral surfaces juxtaposed in a plane of axial symmetry between an inner forming mandrel (M) and an outer, rotating forming tool (R); the mandrel and the outer tool have respective outer working surfaces (A, C) which are axially symmetrical with respect to the plane (p); the mandrel and the outer tool are rotated and approached so as to radially compress and plastically deform the annular blanks (20, 30) between the working surfaces (A, C). (Figure 6)
