Abstract: A control device for timed control of a filling pressure during filling of a press die with a pasty or slip-like mass has a pressure sensor detecting a pressure in the press die, a threshold stage to which a corresponding pressure signal is fed from the pressure sensor, a timing element on which the threshold stage acts to maintain a filling pressure at an intended value during determinable holding time, a second threshold stage to which the pressure signal can be fed, and a logical gate to which outputs of the two threshold stages are connected and which generate a trigger signal for timing element when a particular value simultaneously exceeds a first threshold value of the first threshold stage and falls below a second threshold value of the second threshold stage.
