ABSTRACT:
An ink fountain construction for a printing press having a trough extending adjacent and parallel to the fountain roller to define a control space occupied by a flow control strip. The control strip is made up of a series of separate and independent flow control segments in the form of identical blocks of rectangular shape arranged snugly side-by-side for zonal control of the ink film fed to the roller. Each segment is rigidly secured to the frame at its lower end. Each segment has a relatively thin central section and is sprung forwardly to bias the presented upper edge of the segment against the fountain roller. A set of pull rods connected to the upper ends of the segments have adjusting means at the rear end to draw the connected segment rearwardly to define a gap with the fountain roller to establish the rate of ink feed in the respective zonal position. A resilient sealing strip is sandwiched between the front edge of the frame and the flow control segments under edgewise compression thereby to follow the movements of the individual segments over the entire range of adjustment while maintaining a constant seal between the segments and the front edge of the frame.
