Abstract
A bending method for tubular elements in a bending machine (1) comprising a central vice (3) and two moving bending heads (4, 5) provided with bending means (11) and positioned on the sides of the vice (3). The method comprises the following operations: positioning a tubular element (T) inside the vice (3) and the bending heads (4, 5); holding a tubular element (T) in bending position inside the vice (3) and the bending heads (4, 5); rotating the bending means (11) of the bending heads (4, 5) to bend the tubular element (T), the rotation of the bending means (11) being combined with the travel of the bending heads (4, 5) with respect to the vice (3) to make bends with variable radius of curvature on the tubular element (T). <IMAGE>
