A paper machine is a collective term for a complete set of equipment that forms a paper web for pulp, including a main unit such as a pulp box, a mesh unit, a pressing unit, a drying unit, a calendering machine, a paper rolling machine, and a transmission unit, as well as auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery.

A machine that produces paper by dewatering the pulp water suspension that meets the requirements of papermaking through a filter, mechanical extrusion dewatering, and drying processes. The paper machine consists of three main parts: forming, pressing, and drying, which complete the above process. It is equipped with necessary finishing, coiling, and transmission devices, as well as auxiliary systems such as pulp supply, pulp and white water circulation, vacuum, ventilation and exhaust, paper loss treatment and lubrication, and self-control.
