ABSTRACT:
An ink metering arrangement for a printing press including a fountain roller having a plurality of slides arranged edge-to-edge in respective column positions, each slide being adjustable so that its tip forms a gap with the roller thereby determining the rate of ink flow in the corresponding column position. Each slide has a reversible motor for driving the slide over a limited range of movement with respect to a slide reference position. A potentiometer is connected to the motor for producing an electrical output signal corresponding to the degree of slide displacement, the potentiometer having a stop to establish a reference output condition. A slip clutch is interposed in at least one of the motor connections so that when the motor is energized in a first direction the potentiometer and slide are both driven to their reference positions accompanied by relative slipping movement of the clutch notwithstanding the fact that the tip of the slide may have been shortened by wear against the roller. Upon reversal of the motor the potentiometer thereafter provides an accurate measure of the opening at the gap.
