  • Method of operating a press
    Patent number: 5297478
    Abstract: A method of operating a press designed to eliminate fluctuations of the pressing force in a press. The maximum actual value of the stroke's pressing force is averaged over n strokes. The average value is compared with a desired value, and when there is a deviation, a position adjustment in the press is triggered by means of a controller. An example of the press position adjustment is a displacement of the axis of the slide.
