Abstract: An apparatus for application of liquids to a continuously conveyed outer layer having a rotating plate which is horizontal and parallel to the outer layer or with a deviation of up to 15° from horizontal, wherein a liquid applied to the rotating plate is ejected centrifugally from the rotating plate via rotation and then, via gravity, passed onto the outer layer below the rotating plate, is provided.
