ABSTRACT:
In an imprinting device including a pressure cylinder and a movable counterpressure cylinder, the counterpressure cylinder is disposed opposite the pressure cylinder and is elastically attached to a rocker which is pivotal about a point. The device includes at least one electro-dynamic actuator so as to vary the axial distance between the pressure cylinder and the counterpressure cylinder in that the actuators move the rocker about its pivot point.
