Calendar roll

A cast-iron roll that is is part of a series of metal rolls at the end of a paper machine. When the paper is passed between these rolls they increase its smoothness and the glossiness of the surface. The amount of pressure controls the degree of smoothness of the paper. Most papers other than antique finished papers are calendered. The type of finish that is achieved using calendering is called an eggshell finish, vellum finish, or english finish.
