Abstract: An ink fountain device includes a fountain roller, a blade, a pair of ink dams, a compression coil spring, and a fountain roller moving device. The fountain roller is rotatably supported by an eccentric bearing. The blade is arranged close to the fountain roller. The distal end of the blade forms a clearance, with respect to an outer surface of the fountain roller, where ink is to be supplied. The pair of ink dams are arranged to be substantially perpendicular to the blade and oppose each other in an axial direction of the fountain roller, and are supported to be movable toward and away from the outer surface of the fountain roller. The compression coil spring biases the ink dams to move toward the outer surface of the fountain roller. The fountain roller moving device pivots the eccentric bearing so as to move the fountain roller.

Abstract: An ink chamber doctor, bearing two doctor blades that are arranged in the shape of a roof can be placed in position at an anilox roller of a printing machine and moved away from the same. To guarantee that the central plane of the ink chamber doctor always agrees with a diametral plane of the anilox roller so that the result is a uniform wearing of the doctor blades, the side faces of the strip-shaped housing of the ink chamber doctor bear guide means, which can be used in guides of the side members. The ink chamber doctor can be slid in the guides at least in its end region facing the anilox roller up to its positioning at said anilox roller in a plane that includes both the central plane of the ink chamber doctor and also the axis of the anilox roller. Furthermore, means for pressing the ink chamber doctor against the anilox roller and/or for holding the ink chamber doctor at the anilox roller are envisaged.
