Metal belt calender In metal belt calendering a one-metre-long calendering zone is formed between a heated metal belt and a heated thermo roll. Figures 1 and 2 show schematic drawings of a metal belt calender. The extended calendering dwell time and high thermal energy of the calendering zone effectively plasticise the web surface. Only low
