Abstract
An ink-applying device includes a rotary ink-application roller and a rotary dosing roller positioned between the ink-application roller and a funnel-shaped ink reservoir filled with ink. A bottom wall of the dosing roller is formed with a longitudinal row of conical holes of differing diameters. A number of dosing chambers of differing diameters are formed, respectively in the circumferential surface of the dosing roller to receive ink from the ink reservoir through those holes and to transmit it to an ink-application roller upon rotation of the dosing roller. A plurality of vertically movable plungers are mounted in the ink reservoir to selectively close or open the filling holes in the bottom wall communicated with respective dosing chambers in the dosing roller. A predetermined ink profile on the dosing roller may be obtained in each ink zone by selecting holes and dosing chambers to be closed and open.
