Zusammenfassung:	The applicator, to coat one or both sides of a paper or cardboard web (in)directly with a liquid or paste medium (2), has an edge pressure unit (28,30) to apply pressure to the doctor (18) near an edge zone of the applicator roller (4) or counter roller or the paper web. A higher pressure is applied to the doctor (18) at the edge zone, than pressure (20) applied to the applicator roller (4) or the counter roller or web at the application zone, so that an uncoated edge strip remains at the applicator roller (4) or counter roller or web.
