Abstract
A baffle for use in rotary newspaper printing press ink reservoirs. In such ink reservoirs the inking cylinder, while rotating at high speed contacts ink within the reservoir. Conventionally, the high speed rotation of the inking cylinder creates vibrations and turbulence in the ink, such that air is forced between the rotating surface of the inking cylinder and the printing ink, causing bubbles and non-uniform inking of the ink cylinder. The present system includes a series of baffles positioned within the ink reservoir so as to inhibit turbulence and enhance the flow of ink onto the surface of the rotating cylinder.
Claims8
In a printing system of the type embodying a rotatable inking cylinder contactable with printing ink within an ink reservoir, the improvement comprising:
- A. a baffle supported in said reservoir adjacent said inking cylinder, said baffle further including:
- i. a series of vertically disposed plates mounted in side-by-side array perpendicularly to the axis of said inking cylinder;
- ii. a unitary front ink flow guide interconnecting said plates along the axis of said inking cylinder, so as to define an ink into contact aperture in the upper portion of said ink flow guide and an ink outflow aperture in the lower portion of said ink flow guide, a median portion of said ink flow guide intermediate said ink into contact and outflow apertures defining a transverse baffle across said reservoir and in parallel with the axis of said inking cylinder, and
- iii. a unitary back ink flow guide interconnecting the bottom rear of said vertically disposed plates, so as to define an ink outflow guide across the bottom of said reservoir.
