The object of the calender for cloth and paper is to give the material a perfectly smooth and equal surface, and sometimes to produce a superficial glaze, as in certain cotton and linen fabrics and what is specifically called calendered paper, or a wavy sheen, as in watered silk, etc. The larger rolls in such a calender are usually made of solidified paper or pasteboard turned exactly true, with intermediate castiron cylinders. Calenders are attached to paper-making machines for expressing the water from the felted web of paper, and for the finishing processes of smoothing and glazing. They are also used for spreading india-rubber into sheets suitable for making rubber fabrics, etc.
