ABSTRACT:
An ink fountain formed of a trough and fountain roller, the trough having a recess along its presented edge which defines a ledge surface. A metering bar of durable resilient plastic, and which is of "L" cross section, has a first leg which occupies the recess and a second leg which overlaps, and is sealed to, the bottom of the trough, with the corner of the metering bar defining a gap. Adjusting keys are spaced along the metering bar, each key having a rotatable stem carrying an eccentric at its tip. The first leg of the metering bar has a groove of constant width extending along its inner surface, parallel to the fountain roller, in which all of the eccentrics are snugly received for localized adjustment of the gap, positively in both directions. A resilient sealing strip interposed between the ledge surface and the metering bar seals the second leg of the metering bar with respect to the frame.
