ABSTRACT:
There is provided an inking unit comprising an ink circulating assembly and means for moving a platform on which said ink circulating assembly is provided. The ink circulating assembly includes the ink fountain provided in an ink reservoir, ink outlet means for introducing the ink into the ink fountain, the ink reservoir having an open top and designed to surround the ink fountain from beneath the ink fountain, a screw conveyor arranged along the longitudinal direction within the ink reservoir for conveying the ink mixing the excess dampening water therewith and diffusing the excess dampening water therinto, and a pipe connecting between the ink reservoir and the ink outlet means. The means for moving the platform includes a lifter for vertically moving the platform, and casters for horizontally moving the platform. Thus, the means for moving the platform can be used both as adjustment of a position of the ink fountain in relation to the roller and as removal of the ink circulating assembly to repair and/or to change one to another.
