Abstract (en)
[origin: EP0602431A1] To reduce the stoppage times of a rotary intaglio printing machine and the amount of waste occurring, provision is made in a doctor blade arrangement, in which a doctor blade extending parallel to the axis of rotation of the forme cylinder (1) is pressed against the forme cylinder with the aid of a doctor blade beam (25) to scrape off the excess ink, for the doctor blade to be formed by a strip (20) which is so flexible that it can be wound and unwound around axes running transversely to its longitudinal direction, for the doctor blade strip to be mounted and guided on the doctor blade beam in such a way that it is displaceable counter to and in the longitudinal direction, for the length of the doctor blade strip to be far greater than the axial length of the forme cylinder, and for a winding device (28, 29) to be arranged in each case in the region of the axial ends of the forme cylinder for winding and unwinding the doctor blade strip. Using a drive device, the doctor blade strip can be displaced in the longitudinal direction during the printing operation, in which case it is unwound from the one winding device and wound onto the other winding device. <IMAGE>
