  • Method and equipment for cleaning and maintaining rolls
    Patent number: 6905573
    Abstract: 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.
