After being baked in the oven, the finished paper is peeled off the drying cylinder and rolled up into bundles using a paper reel. As the pulp is transferred from the mesh belt to the drying cylinder, some pulp fibers will adhere to the drying cylinder. After the pulp is dried and paper is made, some fine fibers will adhere to the surface of the drying cylinder, resulting in the next sizing, the points where the fibers are attached cannot be sizing, or the sizing is too little. After the pulp is dried, the corresponding points will form small holes or pits on the paper, thus affecting the quality of the entire paper.
