ABSTRACT:
A machine and method for adjustment of the tooling of a forming machine while continuously operating such machine. The adjusting device being located in a movable or stationary machine part, such as the upper tool part. A measuring device for measuring the cutting and forming result, the measuring signals of which are used to set an actuator which actuates the adjusting device is included. The adjusting device can be actuated by a servo-motor fixed with respect to a stationary machine part. The output shaft of the servo-motor can be coupled with the adjusting device via a transmission arranged on the movable machine part, the driving-sided part of the transmission being arranged on the output shaft of the servo-motor to be slidably displaceable in the direction of movement of the movable machine part and rotatable with the motor output shaft.
