Abstract

An apparatus for applying liquid of a pasty application medium to a moving web includes a curtain applicator unit, which discharges the application medium onto the web as a curtain or veil which moves substantially under the force of gravity, and a device which at least prevents complete coverage of at least one of the edge strips of the web over a predetermined width. According to the invention, this device deflects the at least one edge strip out of the plane of the web, at least in the area of the curtain applicator unit.
