21712-197 ABSTRACT In the continuous application of an even coating on a strip of material (5) that passes over a counter roller (6), in particular paper or cardboard, the coating material is delivered at very low pressure with the help of an applicator roller (2) and under the control of a guide plate (8) and into the applicator gap (7) that is formed by the counter roller and the applicator roller. The coating material is dosed by means of a dosing element (15), partially de-watered in the vicinity of a layer that is close to the strip of material so as to form a blocking barrier, and then finally dosed in a final dosing assembly by means of a final dosing element (24) at very low application pressure. A three-stage process of this kind, or the apparatus which is suitable for carrying out this process, makes it possible to achieve consistently good coating quality at comparatively high throughput speeds of the material and at extremely low application weights.
