Abstract

The method for bending sections and the like according to programmable radii of curvature is applied in an apparatus that includes a bending assembly (1) provided with a central abutment tool (3) and with an eccentric section bending post (4). The method entails actuating the discontinuous advancement of the section (2) to be bent in abutment with the central tool (3) in step with alternating angular strokes of the eccentric bending post (4), so as to make the section (2) follow the envelope of a virtual mandrel (5) whose radius of curvature can be programmed by virtue of an electronic processing means that is suitable to control or indicate the advancement of the section (2) to be bent and the angular strokes of the eccentric bending post (4).
