<p>A roll bending machine for bending plates or iron sheets with a programmable work cycle; a central processing unit (CPU) by suitable sensoring means (21, 30, 33, 34) controls the working positions of the rolls (12, 13, 14) of the bending machine adjusting them according to programmed data which can be modified each time by an operator or automatically, according to the characteristics of the plate (15) being worked. The use of a three-point sensing device (35) enables the diameter which the machine is conferring to the plate (15), to be controlled, intervening to make the necessary corrections. <IMAGE></p> |
