Forming Rolls And Calenders - Calendering and milling are sufficiently similar to enable them to be treated together. Valmet’s calender roll covers provide longer service intervals and optimum paper or board properties. Web therefore, when calendaring polymers, the material passes three nip regions. In case of calenders with two and three rolls, the rolls are normally arranged vertically over one another. Besides providing better marking resistance, our calender covers allow much higher speeds and temperatures without damage than conventional alternatives. Calenders are sometimes misspelled calendars.

Valmet’s calender roll covers provide longer service intervals and optimum paper or board properties. Calendering is a mechanical process by which rubber is pressed into textiles (cloth, fabric, tire cord) forming composite sheets. The first pass is the ‘‘feed’’ pass, the second, the ‘‘metering’’ pass, and the third, the ‘‘sheet formation, gauging, and finishing’’ pass (1).
