The working mode of the calender

- Jul 31, 2019-

The calender works in a continuous rolling mode. The printed matter is conveyed from the paper feeding table to the calender belt between the hot pressing roller and the pressing roller, and the coating is attached to the surface of the calendering belt to be calendered under the action of temperature and pressure. The calendered coating layer is gradually cooled to form a shiny surface layer. The calender belt is a specially treated stainless steel endless steel belt. The hot press rolls are internally equipped with sets of far infrared heating sources to provide the heat required for calendering. The pressure of the pressure roller is mostly electro-hydraulic pressure regulation system, which can accurately meet the pressure requirement in calendering. The calendering speed can be controlled by a speed-regulating drive motor or a slip motor.
