- 摘要：
- Ink metering device in an ink duct for offset or letterpress printing machines having an ink duct roller with metering and support regions disposed adjacent one another in axial direction of the ink duct roller, the metering regions being formed of metering elements adjustable zonewise to varying ink gap spacings, and the support regions continuously contacting the ink duct roller at least indirectly, under spring biasing force, including a flexionally elastic support rail extending over the entire length of the ink duct roller, the support regions being rigid support ledges formed on the support strip, the metering elements being disposed between the support ledges, and adjusting means operatively associated with the metering elements for zonally varying the ink gap spacings for the respective metering elements.
