Abstract
A method for cleaning cylinders of a rotary printing press having washer and suction devices and an adjacently mounted dryer which shortens the down time during the cleaning operation and at the same time satisfies safety requirements. At the beginning of a cleaning process, the dryer is reduced from its normal operating output level to a predetermined lower operating output level which eliminates the risk of combustion with cleaning fluid vapors. At the end of the cleaning process, the operating output of the dryer is increased from its reduced level to its normal operating level in a significantly shortened period of time, as compared to conventional practice, resulting in reduced down time for the printing machine during the cleaning operation.
