ABSTRACT:
In an ink metering device for an ink trough--ink roller combination, circular-cylindrical buttons rotatably inserted into the bottom plate of the ink trough are used as ink metering elements. One face end of the buttons has raised projections acting as metering ridges, which are either in contact with the ink roller 2 or spaced apart therefrom by a specific distance. The projections acting as metering ridges preferably extend diametrically across the face end of each metering element. By rotating the metering elements about their axis of rotation, which is approximately perpendicular to a tangent of the ink roller, the ink metering can thus be varied from a minimum amount (zero) to a maximum (for complete inking), depending on the rotational position of the raised projections.
