Calender is an important technical equipment for finishing paper surface in the process of papermaking. Calendering is a process that uses Calender to process paper or cardboard containing certain moisture to improve the smoothness and gloss of paper and to control the thickness of paper or cardboard paper to a certain extent. Paper is a wide sheet material. In order to press the paper evenly on the whole width, the points on the busbar contacting the working two rollers must be meshed evenly in each pressure area to produce the same line pressure. For a Calender consisting of more than two Calender rollers arranged vertically, because of the existence of intermediate rollers, this ideal requirement can only be met when the roller surface contacts the bus bar in a straight line under working conditions.
