Abstract
The invention relates to an applicator for coating webs of paper or cardboard, with a backing roll for supporting the web at least in the area of the applicator, and with a nozzle for supplying coating mixture. The nozzle is connected to or integrated with a support beam. A guide surface has an angular, sharp parting edge on the end of the guide surface and is attached to the support beam. The guide surface--toward the parting edge --steadily approaches the shell surface of the backing roll, while in the area of the parting edge deviating at an angle between 0.degree.-10.degree. from the tangential direction of the backing roll existing adjacent the parting edge. The guide surface and the backing roll define an applicator gap in which a hydrodynamic pressure prevails.
