摘要：
In a coating method for direct or indirect application of a coating medium onto a moving surface, the amount of coating medium dispensed by an applicator device within a given time period and the actuating force that is exerted on the metering element, in order to achieve a coating layer of a desired coating weight, are altered independently of each other. In a relaxation operation mode, the amount of coating medium applied within a given time period is reduced when the coating weight exceeds a desired value; when the coating weight falls below the desired value, the actuating force exerted on the metering element is reduced. In a contact pressure based operating mode, the amount of coating medium applied within a given time period is reduced when the coating weight exceeds a desired value; when the coating weight falls below the desired value the actuating force exerted on the metering element is increased. When the coating weight falls below the desired value, the amount of coating medium applied within a given time period is increased and the actuating force exerted on the metering element is reduced, while keeping constant the contact pressure of the metering element against the moving surface.
