Abstract:
1. A rotation transmitter adapted for use with a forme cylinder of a printing press comprising: a forme cylinder body supported for rotation about an axis of rotation; a rotor adapted to rotate with said cylinder body and having a rotor contact surface; a stator fixed against rotation and having a stator contact surface; a first number of flow channels in said stator and each adapted to receive a flowable medium; a second number of flow channels in said rotor and each adapted to deliver the flowable medium received from said stator to said cylinder body, said rotor contact surface and said stator contact surface being in engagement during introduction of the flowable medium into said cylinder body, said second number of rotor flow channels being greater than said first number of stator flow channels; means connecting said rotor to said cylinder body for rotation with said cylinder body; first and second printing plates arranged one behind the other on said forme cylinder body in a direction of said rotation of said forme cylinder body; a first group of at least four inlet openings in selected ones of said rotor flow channels; a second group of at least four inlet openings in other selected ones of said rotor flow channels; and a group of outlet openings in said stator flow channels, said first group of said inlet openings being in fluid communication with said group of outlet openings in a first rotational position of said forme cylinder, said second group of said inlet openings being in fluid communication with said group of outlet openings in a second rotational position of said forme cylinder, said second rotational position being different from said first rotational position.
