A calender is a series of hard pressure rollers used to finish or smooth a sheet of material such as paper, textiles, rubber, or plastics. Calender rolls are also used to form some types of plastic films and to apply coatings.[1] Some calender rolls are heated or cooled as needed.[2] Calenders are sometimes misspelled calendars.
