Abstract

Method and device for the fabrication of tubes (5,6) with an oval or elliptical section that comprises a tube (5,6) with a circular section placed along a path defined by a plurality of rollers (3 and 4, 7 and 8, 9 and 10, 11 and 12, 13 and 14). The plurality of rollers comprises couple of rollers (3 and 4, 7 and 8, 9 and 10, 11 and 12, 13 and 14) placed diametrically opposed to each other and defining the path. The passage through the path forces, therefore, the tube (5,6) against the throats (30,40) of the rollers (3 and 4, 7 and 8, 9 and 10, 11 and 12, 13 and 14) causing its deformation for its entire length.
