New tools help papermakers run, monitor, and maintain roll covers

The use of nano-particle technology, thermal imaging, and imbedding sensors in covers are improving calender roll cover performance, runnability and maintenance. The advances in hot soft-nip calendering and supercalendering have improved the state of calendering technology and overcome the limitations of traditional supercalenders and machine calenders. The systems such as monitoring equipment and processes are recommended and utilized for detecting, monitoring and addressing the cover issues. The North American calandering market is very diversified and the mill suprintendents and managers are teaming up with suppliers of rolls and covers to improve sheet quality and develop high-revenue grades.
