Wet end measurement system for MD and CD quality monitoring and control - It will increase the likelihood of making better paper

This unique non-scanning sensor technology, measures the sheet water weight at the wet end of the paper machine and generates an MD drainage profile p er machine ply. This measurement allo vs monitoring of MD drainage characte ristics during grade change and sheet breaks, which presents new opportunit ies to further improve paper quality. Case studies are presented to) highli ght the identification of MD variation on twin-wire and multi-ply machines where little visibility into the process is currently available with tradit ional scanning gauges.
