摘要

An ink metering device for the fountain roller of a printing press including a plurality of ink slides in the ink fountain wherein each slide has a metering element of duct width movable by an adjusting screw which is connected to an adjusting pin and biased by a spring toward the fountain roller to produce a metering gap wherein the spring element is supported between a fixed part of the ink fountain and the metering element and a length-equalizing element is provided permitting transmission of an adjusting movement to the adjusting pin such that the lenth-equalizing action is effective only by overcoming the force of the spring element. In the preferred embodiment, the adjusting pin is rigid with the metering element and the other end is screwed into a length-equalizing coupling connected to a selective drive mechanism with the intermediate portion of the pin being supported for axial movement in a guide block.
