Abstract
A run-up control for the pressure cheek in a drawing apparatus achieves stoppage times during the run-up phase by having a pressure cylinder with first and second pressure spaces as well as a control piston which is fixed in its position in the control cylinder when the second pressure space is acted upon with pressure. The control piston is fixed in its position by a piston rod, a fixed stop and an adjustable stop. The first pressure space is in a continuous flow connection with a mash pressure space which is reduced when the pressure cheek runs up so that the volume of the second pressure space determines the point in time of the stoppage time in the run-up phase of the pressure cheek.
