ABSTRACT:
An arrangement for application of liquids, such as a coating unit for a printing press, with a liquid supply above the metering gap formed between a metering roller and an applicator roller interacting therewith, a partition designed to damp vibrations dividing the liquid supply along the length of the rollers in order to compensate for turbulence, resonance and irregular air occlusions as far as the metering gap and to prepare uniform quantities of liquid. For this purpose baffle plates at right angles to the rollers have edges adapted to conform to the curvature of the roller surfaces to define a communicating gap with the roller surfaces, said baffle plates being arranged in a fixed position just inboard of the ends of the two rollers and formed as a unit with the partition defining a constant communicating gap with applicator roller, the partition having regularly arranged communicating channels in the form of holes, preferably a first row near the continuous bottom edge and a second row above the first one.
