  • Patent number: 6755130
    Abstract: An automatically controlled cleaning system has a cleaning fluid reservoir with a feed of the cleaning fluid to the rotating bodies to be cleaned via a cleaning element for each body. Its serviceability can be monitored, in particular erroneously exceeding the critical quantity of cleaning agent per unit time during the cleaning of the rotating bodies of the press can be detected and countermeasures can be initiated, by constructing the cleaning reservoir as a pressure container which can be pressurized from a compressed-air source via an electronically drivable changeover valve V1, and by implementing each feed of the cleaning fluid to the rotating body by means of a fluid feed line in which there are installed at least one electronically driveable changeover valve V4 that controls the flow, and at least one further electronically driveable changeover valve V5 which controls the expulsion quantities and expulsion times of the cleaning fluid.
