  • Patent number: 10166757
    Abstract: An inking system of a printing press includes an impression cylinder for guiding a printing substrate, and at least one ink-transfer roller. The ink-transfer roller includes a cylinder mandrel, on which at least one cylinder sleeve is concentrically displaceable, and bearing blocks, in which ends of the ink-transfer roller are mounted and which are independently displaceable in the radial direction of the impression cylinder. The ink-transfer roller can be set against the impression cylinder or any other ink-transfer roller, with a bearing block being detachable from one end of the ink-transfer roller and displaceable relative to the ink-transfer roller so that the cylinder sleeve can be removed via this one end. A stop device, with which the cylinder sleeve can be brought into contact, has components that are movable in the axial direction of the print roller. The movable stop device components can be decelerated via a force-providing element.
