Abstract
A doctor blade device of a rinsable ink application device of a rotary press is cleaned by first pumping ink back out of an ink chamber of the doctor blade device via a discharge line into an ink tank. Subsequently, from a solvent tank and via a feed line, solvent is directed into the ink chamber. During a predetermined time span, solvent is directed via the discharge line into the ink tank. Subsequently, the solvent, which is still contaminated with ink, is pumped into a contaminant chamber within a predetermined time span. The solvent flow from the solvent tank is interrupted and the solvent is pumped into the contaminant tank. Fresh solvent is then pumped via the feed line into the ink chamber, the suction line to the solvent tank is closed, and the solvent is pumped via the feed and discharge lines within a closed rinsing cycle for a predetermined amount of time. The circulating solvent is then directed into the contaminant tank.
