- calendering
-
Process of smoothing and compressing a material (notably paper) during production by passing a continuous sheet through a number of pairs of heated rolls.The rolls in combination are called calenders; they are made of hardened steel or steel covered with fiber. In paper production, they typically exert a pressure of 500 lbs per linear in. (89 kg per cm). Coated papers are calendered to obtain a smooth, glossy finish. Calendering is also widely used in the manufacture of textiles, coated fabrics, and plastic sheeting.

▪ manufacturing processprocess of smoothing and compressing a material (notably paper) during production by passing a single continuous sheet through a number of pairs of heated rolls. The rolls in combination are called calenders. Calender rolls are constructed of steel with a hardened surface, or steel covered with fibre; in paper production, they typically exert a pressure of 500 pounds per linear inch (89 kilograms per centimetre). Coated papers are calendered to provide a smooth, glossy finish.Calendering is also widely used in the manufacture of textile fabrics, coated fabrics, and plastic sheeting to provide the desired surface finish and texture.* * *
