Regulating the calendering process

The calendering process is regulated by highly accurate OD displacement measurement sensors arranged in pairs at three positions on the belt, which measure thickness using the difference in the measured values. The sensors reliably determine any deviations in thickness of less than 1 μm. Signals are processed and differential values calculated in the associated evaluation unit.
