ABSTRACT:
The present invention is directed to a coating apparatus for a printing press. The apparatus includes an oscillating-metering roller having an internally disposed oscillation mechanism for delivering to a printed web a uniform fluid coating free from coater-imposed aberrations. The oscillation mechanism includes a translating means for translating a rotational movement into an oscillating movement, a velocity-modifying means for modifying the velocity of the rotational movement and a velocity-regulating means for providing a regulated, consistent velocity.
