Abstract
For the application of a coating material onto a running material web, particularly a paper or cardboard web, a cylinder guides the web of material while a dosing element extends over the work width and has a surface which together with the cylinder forms an application gap converging in the travel direction of the web. In order to be able to apply various coating materials at high web speeds evenly and without disturbances, even at low application weights, the dosing element is supported swingably about an axis parallel to the cylinder, the radius of its surface guiding the coating material increases continuously in the travel direction of the web up to the dosing line and the surface ends at the dosing line with an edge whose radius is less than 8 mm.
