A drawing apparatus in drawing stages of a press, having a pressure cheek divided into segments, to the corner areas of which pressure cylinders are applied. The pressure cylinders are fixed to the press. Their piston rods, by way of pressure rods, act upon a liftable and lowerable console. At least one locking cylinder which is fixed to the frame is provided which, by way of a lift bridge, is applied to the console and, corresponding to the pressure which acts upon it, prevents an upward movement of the console and thus of the pressure cheek. The point in time of the stop stage in the upward-moving stage can be determined by the valve control of the pressure in the lacking cylinders.
