Abstract
Abstract Ink applicator means for a printing press for applying liquid ink to a roll therein comprises a hollow cylindrical tube adjacent the roll and having a chamber therein. The tube has a longitudinal slit in one side thereof communicating with the chamber and ink inlet ports for communication with the chamber. A longitudinal member of rectangular cross-section is axially disposed within the tube chamber, and cooperates with the interior wall of the chamber to define metering orifices which control passage of ink from the ports to the slit. The longitudinal member is provided with depressions in one surface thereof which extend from a location in the vicinity of the inlet ports along the longitudinal member to equalize fluid pressure in the tube.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
Fluid applicator means for applying ink to a surface of a printing press roll comprising, a hollow tubular member adjacent said roll surface and having a chamber therein, said member having a longitudinal slit in one side thereof communicating with said chamber, at least one ink inlet port communicating with said chamber, and a longitudinal member axially disposed within said chamber, said longitudinal member having a cross-sectional configuration which differs from the cross-sectional configuration of said chamber and having a surface against which ink from said inlet port impinges, said longitudinal member having at least two portions which cooperate with the wall of said chamber to define at least two metering orifices to control passage of ink from said port to said slit, and said longitudinal member being provided with at least one depression in said surface which depression extends from a location in the vicinity of said inlet port along said longitudinal member.
