　　the paper machine can be roughly divided into the main machine part and the auxiliary system part;

　　the host part is roughly divided into wet parts, cadres, and curls. the wet part can be understood as the part of the paper with a relatively high water content; cadres are the parts of paper that have little moisture and are considered dry; curling is the mechanism by which a page of paper is rolled up.

　　referring to the picture content, the headbox, mesh part, and pressure part can be considered as wet parts; drying, gluing, coating, and calendering are considered cadres; and then there's curling. please do not delve deeply into the concept of classification as it does not involve academia.

　　auxiliary system, literally, refers to the part that assists the host in implementing its functions.
