A machine for bending sections (2) having a longitudinal axis (3) and a constant cross section along the longitudinal axis (3) feeds the sections (2) longitudinally in a first direction (D1), and has a first and a second annular die (11, 12); an ass (15) connected to the second annular die (12) and movable in a plane perpendicular to the first direction (D1) to move the second annular die (12) into a number of operating positions with respect to the first annular die (11) to bend the sections (2); and a joint (22; 39) connecting the first and the second annular die (11, 12), and which forces the second annular die (12) to assume a given position with respect to the first annular die (11) for each position assumed by the assembly (15). |
