  • Damping system for an offset press
    Patent number: 4991502
    Abstract: In the damping system for an offset press according to the present invention, the rotational speed of a motor, which drives a water-applicator roller, is controlled such that the difference or slip between the peripheral speed of the water-applicator roller and the peripheral speed of the plate cylinder can be set to a desired value. To this end the damping system comprises a water-applicator roller which applies water, supplied from another roller, to a plate cylinder of the offset press. The water-applicator roller is in contact with the plate cylinder. A motor drives the water-applicator roller. A detecting device detects the rotational speed of the motor. A device detects the peripheral speed of the plate cylinder. A slip input device sets a desired difference between the peripheral speed of the plate cylinder and the peripheral speed of the water-applicator roller.
