It is mainly composed of a screen, a press and a dryer. In the papermaking process, since the fibers on the sticky screen cannot be removed in time and effectively, the fibers remaining in the pulp will have an adverse effect on the papermaking process and the quality of the paper sheets, such as blocking the screen gap, contaminating the forming screen, felt and dryer screen, adhering to the pipes of the paper machine and making it difficult to clean, and being brought into the paper surface and affecting the quality of the paper sheets.
