A printing cylinder of a printing machine that can be immersed in an ink pan is provided with a doctor blade that can be adjusted to it. In order to prevent ink from spraying outward, rings are placed that can rotate freely, but cannot be moved in the axial direction, and carry holding arms that hold wipers in the region between the ink pan and the doctor blade. The rings are held by torque supports in such a way that they cannot rotate with respect to the machine frame.
