Abstract
An ink fountain including a frame defining a horizontal slot adjacent the fountain roller. Arranged side by side in the slot is a metering assembly in the form of a series of flat slides each having a cam assembly at its rear end for adjusting the position of the slide with respect to the fountain roller thereby to meter ink in predetermined thickness in respective zones. Each slide is formed of a body having secured thereto a rectangular tip portion formed of resilient plastic. The tip portion of each slide has embedded in it a blade of wear resistant spring metal, the blade being coextensive with the width of the slide and so oriented as to present a flat face to the fountain roller defining, with the fountain roller, a sharply acute cusp. The rectangular tip portion of each slide is relieved in the region just behind the spring metal blade to permit the blade to flex broadwise resiliently and accommodatingly when the slide is advanced to bring the edge of the blade against the surface of the fountain roller thereby to achieve a seal between the blade and the fountain roller with only limited reaction force being exerted between them.
