ABSTRACT:
An improved corrugated board manufacturing apparatus and method including precise web moisture and temperature control is disclosed. The apparatus includes steam driven manifolds for zone drying of the web using pressurized steam to reduce moisture and equalize the moisture content across the web. Moisture sensors and temperature sensors are implemented to scan the web and provide feedback information regarding web moisture and temperature. Wrap arm position is automatically controlled to obtain ideal web temperatures for corrugated board production. Web speed and take-up ratios are monitored to determine when process parameters are out of limits which may cause waste. An improved hot plate section including variable pressure applied to the web as well as variable steam supplied to the hot plates results in a more effective process control loop in achieving and maintaining web temperature for curing the adhesive and preventing warping.
