<p>A control system for automatic control of a unit for coating a moving web e.g. of paper or cardboard using a curtain coating technique. An apparatus (10) for direct or indirect application of a liquid or pasty coating medium (14) onto a moving substrate web (18), especially of paper or cardboard, comprising a curtain coating applicator (12); at least one sensor device (46/48/48) to determine the amount of coating composition in the coating layer (14a) on the substrate web (18) and to generate a corresponding coating amount signal ( DELTA G, DELTA G'); at least one regulating device (38/40) to control at least one adjustable setting of the curtain coating applicator (12) upon which the coated amount of coating composition in the coating layer (14a) depends; and a control unit (42) which receives the coating amount signal ( DELTA G, DELTA G') from the sensor device and compares it to at least one set value to enable any necessary adjustment to be made to the settings of the curtain coating applicator.</p> |
