Method and equipment for cleaning and maintaining rolls |
摘要 |
The surface of a web is monitored by a fault detection system ( 20 ), a machine condition monitoring system, a quality measurement system, a web moisture measurement and/or a web temperature measurement and the soiled part of the surface of the roll is detected and localized by means of a soiling monitoring apparatus ( 31, 35; 60 ). A control system ( 41 ) controls a cleaning device ( 40 ) to remove the detected soiling. As a web (W) travels in a paper or board production or finishing process or in finishing machinery the web and/or the surface of the roll is monitored and after a detected deviation the surface thereof is momentarily spread with a liquid while machinery is running at the same time as the web (W) travels over said roll surface. |
