摘要： The apparatus has as many invalidating units (E) arranged next to one another as there are longitudinal rows of security prints on the print carriers (P). Each invalidating unit (E) has a stand (1), a trough (3) vertically displaceable in the latter and intended for receiving ink (4), a centrifugal wheel (7) rotating continuously above the trough (3), and a shutter (11) which interacts with an orifice (10) of a cowl (9) covering the centrifugal wheel (7). By means of a controlled actuating member (6), the trough (3) is adjustable between a raised working position, in which the centrifugal wheel (7) dips into the ink and the shutter (11) exposes the orifice (10), and a lowered position of rest, in which the centrifugal wheel (7) does not dip into the ink and the orifice (10) is covered by the shutter (11). Control takes place whenever a security print previously detected as a misprint and to be invalidated in one or more longitudinal rows of the print carriers passes the orifice (10) of the respective invalidating unit, so that this misprint is sprayed with ink by the centrifugal wheel (7) through the orifice (10) which is then free.

摘要： A liquid transport mechanism for use particularly in transporting and evenly distributing printing ink in a rotary printing machine is disclosed. A plurality of generally cone shaped ink transport rollers are placed about the periphery of one or more ink relief equalizing cylinders. The axes of rotation of the rollers are angled with respect to the axes of rotation of the ink relief equalizing cylinders. The covered surfaces of the rollers, which are disposed generally in pairs, contact the surface of the ink cylinders to form ink bridges which split the ink coating on the cylinders and cross transport it longitudinally along the length of each of the ink relief equalizing cylinders. The ink metering unit in accordance with the present invention uniformly and rapidly equalizes ink thickness without the need for ink zone adjusting screws and doctor blades.
