Abstract

A method of application of a liquid or pasty medium onto a moving material web consisting, in particular, of paper or cardboard, in which a direct application (2) of a liquid or pasty medium (4) onto one side of a moving material web (1) and a contactless deflection (3) of the moving material web along a curved path of motion ensues, the side of the moving material web to be provided with the liquid or pasty medium passing through a concave curvature and the direct application (2) of the liquid or pasty medium ensuing directly ahead of the deflection (3) or during the deflection as a free jet along a contactlessly guided section of the moving material web. Additionally, an apparatus for implementing the method is described.
