  • Ink fountain with a fountain roller in the inking mechanism of printing presses
    Patent number: 6085652
    Abstract: An ink fountain with an ink-duct roller in the inking mechanism of printing presses, with a device for filling printing ink into the ink fountain, is described. The device for filling ink is mounted on a sled so that it can be moved back and forth in the longitudinal direction of the ink fountain. A sensor is fastened to the sled, and when the ink level is too low, the sensor controls the ink feed. Thereby, a precise regulation of the amount of ink added can be achieved by means of a downstream dosing device.
