Xerium Technologies, Inc. has announced full commercial availability of SmartRoll, the industry’s first continuous pressure-sensing paper machine press roll. Xerium has been conducting on-site customer testing since introducing the SmartRoll in late 2008.
The SmartRoll significantly increases production efficiency and reduces downtime by providing a constant stream of true operating condition information to paper machine operators or mill managers while the paper machine is in operation. Xerium’s SMART Technology employs a proprietary embedded sensor system to extract data from the roll cover during machine operation. By enabling on-the-run adjustments, the SmartRoll helps optimize production, reduce energy consumption and control costs.
“Our SMART Technology represents a technological leap forward for paper processing,” says Stephen R. Light, president, CEO and chairman or Xerium Technologies.
Mounted across the width of the roll cover, the SmartRoll sensors are monitored by head-mounted electronics that rotate with the roll and transmit data wirelessly to a dedicated computer. A custom operator interface provides dynamic monitoring of the pressure profile, pressure profile standard deviation, and roll speed, and also provides a historical data log for benchmarking and comparison purposes.
Armed for the first time with accurate real-time knowledge of nip performance, the operator can adjust machine parameters without guesswork to make corrections to the sheet’s moisture profile as it exits the press section. The benefits can include: increased output, reduced downtime, extended press felt life, extended roll cover life, reduced consumption of materials, reduced energy costs, and early warnings of potential roll cover failures.
