This invention relates to an apparatus for displacing shaft -mounting bearing stands, which are secured to carriages, in carriage guides, preferably for displacing the bearing stands of plate cylinders and inking rollers of a printing unit in carriage tracks of the inking unit supports of a multicolor rotary press, comprising screw drives, which are driven by electric motors. To solve the object to provide such an apparatus in which shafts and particularly plate cylinders and associated inking rollers can mutually independently be displaced relative to each other and, e.g., relative to an impression cylinder, the invention resides in that a screw that extends parallel to a single carriage track is rotatably mounted in the machine frame or on the inking unit support and is provided with a drive. A nut which is non-rotatably and axially immovably connected to a bearing stand or to a carriage is mounted on the screw, At least one additional nut is mounted on the screw and is rotatably and axially immovably connected to at least one additional bearing stand or to the associated carriage and is connected to a separate drive.
