Assemblies in a printing couple of a rotary printing press

An assembly in a printing couple of a rotary printing press comprising:

• first and second spaced printing press side frames;
• at least one forme cylinder supported by the side frames, the at least one forme cylinder being loaded with a plurality of printing formes;
• three ink forme rollers supported by the side frames and spaced circumferentially about the forme cylinder for engagement with the plurality of printing formes;
• first and second distribution rollers supported by the side frames, a first of the ink forme rollers being engageable with the first distribution roller and with the forme cylinder, second and third ones of the ink forme roller being engageable with the second distribution roller and the forme cylinder;
• one ink dividing roller supported by the side frames, each of the first and second distribution rollers being engageable directly against the ink dividing roller;
• an ink reservoir;
• an ink fountain roller in the ink reservoir and which picks up ink from the ink reservoir;
• a single ink film roller supported by the side frames and positioned between, and in engagement with, both the ink fountain roller and the ink dividing roller, the single ink film roller having an ink film roller axis of rotation and spaced ink film roller ends;
• at least one ink film roller socket defining a bearing point for the ink film roller axis, the at least one ink film roller socket being fixed to one of the side frames and receiving one of the ink film roller ends;
• and
• a plurality of actuators in the at least one ink film roller socket, the actuators being arranged around the ink film roller end received in the ink film roller socket, and wherein at least this single ink film roller is arranged for radial movement, wherein the radial movement of this single ink film roller displaces the axis of this single ink film roller by displacement of at least one of the ends of this single ink film roller eccentrically in relation to the ink film roller socket which defines the bearing point that belongs to this single ink film roller and which is fixed to one of the side frames, the displacement of the at least one end of the single ink film roller eccentrically, with respect to the ink film roller socket in which that one end of the single ink film roller is received being accomplished by operation of the actuators in the socket.
