<p>The drying rate of the web is precisely controlled by detecting and monitoring web or felt low and high cross-direction temperature profiles. Drying rate modulators are actuated as required to increase or decrease the drying rate to produce a flat temperature profile. The drying rate is varied in response to temperature profile information provided to an automatically or manually controlled central control system by web high temperature and low temperature sensors. The drying rate of web is predicted as a function of observed temp. in locations near to the low temp. detector.</p> |
