<p>The invention concerns a machine for high rate serial bending of a tube, comprising a bending head (1) provided with a radius block (3) and a backing block (4) including at the periphery a groove with semicircular cross-section and means for driving the backing block (4) in rotation coaxial to the radius block (3) so as to drive the tube to be bent (2) and wind it on the radius block (3). The radius block (3) consists of a disc comprising a bevelled panel (30) arranged along a chord of the disc and it comprises means for moving the bending head (1) relative to the axis of the tube (2) along a path (R) passing through the pins (34, 40) of the radius block (3) and of the backing block (4) and means for axially rotating the radius block (3) independently of the displacement of the backing block (4).</p> |
