A method of controlling a multi-roll calender producing a sheet of synthetic plastics, rubber or other elastomeric material comprising sensing the pressure of material being calendered in roll gaps of the calender, which roll gaps follow one after another in the direction of movement of the sheet; adjusting the width of the two gaps formed with mating rolls on opposite sides of at least some of the rolls to cause the difference between the pressures in the two gaps to be as small as is practicable; and maintaining such pressures substantially constant.
