The press section consists of press roller and press felt. The drying section is composed of one or several dryer cylinders. Some fourdrinier paper machines are equipped with mechanical calender to improve the smoothness and tightness of the paper.

1. In tensile strength, vertical and horizontal tension difference of cylinder mould paper is much more than fourdrinier paper.

2. In terms of smoothness, the difference between two sides is considered, the mould paper is generally higher than the fourdrinier paper.

3. In uniformity, the cylinder is generally worser than the long-mesh paper.

4. The paper disease of cylinder is more than fourdrinier paper disease, and easily appear dust, block and the occurrence of edge, brittle and other defects.
