Abstract
Apparatus for applying a liquid coating onto a moving web has one or preferably two rotatable rollers. In the two roller embodiment both rollers lie on the same plane which is at or near the horizontal. The two roller embodiment positions the rollers adjacent each so as to form a press nip between them. The moving web makes contact with one of the rollers, or the single roller along an extended circumferential arc of the roller. Adjacent each roller is a supply apparatus for depositing a liquid on to a portion of the roller jacket not in contact with the web. Wiper rods are associated with each supply apparatus and are biased against the jacket of the roller to make the coating of liquid uniform. Surplus liquid is used to wash the rollers to remove web fibers and glue and pigment particulate to avoid contamination thereby of the supply apparatus and wiper rods. The surplus liquid and fibers and particulate are collected in sumps.
