Abstract: An inking unit in a rotary printing press includes an ink fountain with a ductor blade, a ductor roller disposed adjacent the ink fountain, and one or more ink fountain pans removably disposed in the ink fountain. The ink fountain pan is formed with a duct through which printing ink is conveyed to the ductor roller. The duct is selectively closed and opened with a closure device, which includes a closure member pivotally mounted on the ink fountain pan. The closure member thereby pivots between a first pivot position in which the duct is open and a second pivot position in which the duct is closed.

Abstract: Ink duct of a rotary printing press, having two side walls between which an ink duct blade is arranged, each of the side walls being formed with an arcuate recess at a front end face thereof for bearing against an ink duct roller of the printing press, includes a deformation device disposed at each of the side walls for modifying a contour thereof defining the respective recess formed therein.
