Abstract:
1. A control system for measuring a gap in an apparatus for pressing a traveling paper web, comprising: a support roll and a press apparatus, said press apparatus including a pressure body, said pressure body and said support roll defining the gap therebetween, said support roll positioned underneath said paper web; a frame movably supporting the pressure body; an actuator operatively disposed between the frame and pressure body for selectively moving the pressure body toward and away from the support roll to control the gap size; a sensor mounted in the press apparatus for producing a signal indicative of the pressure on the paper web as the paper web is passed through the gap adjacent said sensor; and a controller operatively linked with the sensor for receiving the signal, determining the measure of the gap as a function of the pressure, and causing the actuator to move the pressure body to control the gap size.
