Abstract (en)
An ink fountain for printing presses is disclosed in which a plurality of metering segments extend along the surface of the fountain roll to control the thickness of the ink film applied to the roll. The metering segments are individually adjustable toward and away from the fountain roll surface by screw and nut actuators in combination with springs which bias the segments toward the fountain roll. Precise positioning of the segments with respect to the roll is provided because the spring takes up all backlash within the actuator threads and any play in the connection between the actuator and the segments and trough. The actuator is structured to prevent actuator-produced forces on the segment in the direction of the roll so that the maximum force of engagement is provided by the spring. The ink trough and segment assembly is pivoted for movement to a service position in which the segments can be removed and replaced without disassembly of the trough assembly.
