Abstract:
A method for one of direct and indirect application of a coating medium onto a moving material web, said material web being one of a paper web and a cardboard web, said method comprising the steps ofapplying the coating medium onto the moving material web with an applicator device, a volume of the coating medium applied within a predetermined time period being adjustable; associating a metering element with the moving material web, said metering element being disposed after said applicator device relative to a direction of travel of the moving material web; exerting an adjustable actuating force upon said metering element to thereby meter the applied coating medium; measuring a coating weight of the coating medium applied to the moving material web; comparing said measured coating weight to a predetermined desired value; reducing the volume of the coating medium applied and concurrently maintaining a substantially constant actuating force within said predetermined time period when said measured coating weight exceeds said predetermined desired value; and reducing said adjustable actuating force exerted upon said metering element and concurrently maintaining a substantially constant volume of the coating medium when said measured coating weight is less than said predetermined desired value.
