For example, the calender disclosed in CN202222028976.2 on January 10, 2023 can adsorb impurities on the raw material, thereby ensuring the cleanliness of the surface of the raw material. The raw material is positioned by the limiting block arranged on both sides of the raw material. Once the raw material paperboard is inclined, it can be found in time by observing the distance between the raw material and the limiting block.
