The ejector pulse is generated as a function of the actual pressure established in the suction gripper unit after its connection to the positive pressure source. A vacuum gripping device suitable for executing this method and including a pressure measurement device for detecting the actual pressure and an electronic control unit used for controlling the control valve device and communicating with the pressure measurement device.
