  • Patent number: 5437227
    Abstract: A doctor arrangement for a rotary intaglio printing machine comprises a doctor to remove excess ink from the plate cylinder. The doctor is in the form of a band which extends parallel to the axis of rotation of the plate cylinder against which it is pressed by a doctor bar. The doctor band is so flexible that it can be wound on and unwound about axes which extend transversely to its longitudinal direction and the doctor band is so mounted and guided at the doctor bar that it is displaceable relative thereto in the longitudinal direction, the length of the doctor band being substantially greater than the axial length of the plate cylinder. A respective winding device for winding on and unwinding the doctor band is arranged in the region of each of the axial ends of the plate cylinder. A drive means displaces the doctor band along the doctor bar during the printing operation when the doctor band is unwound from the one winding device and wound on to the other winding device.
