Abstract
An apparatus is set forth wherein a pressurized cylinder is operative to direct fluid flow from a series of compartmentalized sections within the cylinder operative through separate valving to direct the flow through metered orifices formed in a coextensive matrix pattern throughout the cylindrical wall of the cylinder, and to direct fluid from the cylinder to a plurality of water form rollers to direct the water from the cylinder onto a plate cylinder for use in printing machines.
Claims7
A printing press dampening apparatus in combination with a rotary printing machine, wherein the machine includes a plate roller and at least one transfer roller to direct fluid onto a surface of the plate roller, and
- a water feed roller to direct water to the transfer roller,
- the water feed roller including pressurizing means for directing pressurized fluid interiorly of the water feed roller, and
- a matrix of metered apertures for directing the fluid from interiorly of the water feed roller to the transfer roller and
- wherein each of the metered apertures comprises a conduit orthogonally oriented relative to a cylindrical surface defined by the water feed roller, each of the conduits including a tapered opening within the surface of the water feed roller, and a spherical check ball normally biased to close the tapered opening in a first position and repositioned to a second position spaced from the tapered opening upon contact of the spherical check ball with the transfer roller.
