DAMPENING APPARATUS WITH ROTOR FOR PROJECTING SPRAY

摘要

A plate-dampening apparatus for a printing press projects a spray of dampening liquid onto a transfer roll. The apparatus includes a weir over which dampening liquid continuously spills, and a rotor having projections which are moved at speed to cut through the thickness of the liquid, without striking the weir, as the liquid spills over the wier and project a spray from it.
