ABSTRACT:
A process for the multiple coating of webs which are continuously moving past a coating point, using coating apparatus according to the bead coating process is carried out such that any number of comparatively high viscosity layers is arranged above an accelerating layer which lies below the layers and has a viscosity range of from 1 to 20 mPas and a layer thickness of from 2 to 30 .mu.m. A very small gap width of from 100 to 400 .mu.m is selected between the sliding surface coating head and the web to be coated and only a low reduced pressure is applied under the coating head. By this process, coating rates of 400 m/min and more may be achieved with a good coating quality.
