Abstract (en)
It is described a tube bending machine having a supporting frame (2) on which a tube to be bent (4) is disposed. Right and left forming dies (7, 8) act on the tube (4). A bending tool (9) moved by a rocking arm (21) carries out bending of the tube around the forming dies. The bending tool (9) is also radially movable close to and away from the forming dies, to perform a controlled and precise tube bending. <IMAGE>
