Balancing system for a bending press actuated by at least three actuators (7, 8, 9), the central actuator including an approach section (10) and a complementary section (11). The side actuators are each associated with one of the sections of the central actuator, thus forming two self-contained assemblies (7, 11) and (9, 10); each assembly is controlled by its control loop and the two loops are controlled in parallel. For highly eccentric bending, two distributers (33, 34) suppress the action of the side-actuator with the lowest pressure and that of the central actuator section with the highest pressure. Only one actuator remains operational for each loop, which allows bending to be achieved at the side actuator. |
