This paper will discuss the latest developments in composite calender roll cover technology. The developments that will be discussed are improved wear resistance, impact resistance, temperature resistance, and barring resistance. The focus will be on the physical material improvements in the covers and how these improvements affect the performance of the cover in the calender. In addition, this paper will discuss the impact that these improvements will have on improving grind intervals and reducing unplanned roll changes. The impacts of these changes will be shown for all types of calenders. (soft calender, supercalender and Multi-nip calenders) This paper will also discuss the use of the latest nip monitoring technology in calendering cover applications. A few success stories will be included in this paper.
