ABSTRACT:
Individual disks or roller elements (4) are located, axially positioned next to each other, on a water roller transfer structure. To provide for smooth operation of rollers of a roller train of the machine, the disks or roller elements (4) of the water roller structure are in continuous surface engagement with a receiving roller, forming part of the machine roller train, and driven at machine speed. The disks or roller elements (4) are individually selectively shiftable about the circumference of the receiving roller (5) by deflection of individual angled levers (6) for selective engagement with a water supply roller (2) operating, for example, in a water trough (1), receiving water from the water supply roller. The receiving roller (5) is axially oscillating or reciprocating, and may form part of the inker of the printing machine and, further, has engagement contact with additional rollers (5', 5") of the inker of which one (5"), for example, also is axially reciprocating or oscillating.
