  • Patent number: 7114437
    Abstract: A method for shifting a doctor blade in its longitudinal direction, the doctor blade being set against a cylinder of a printing machine, wherein the shift movement of the doctor blade is such that, for most of the time of the print operation, the shift velocity of the doctor blade is in a range from 0 to 0.1 m/s, and a printing machine having a doctor blade assembly, including a doctor blade arranged to be set against a cylinder, and a shift mechanism for shifting the doctor blade in its longitudinal direction, such that the shift mechanism is adapted to execute the method.
