Paper making machinery is a machinery that includes the preparation of raw materials, pulping, papermaking, until they are made into rolls or flat sheets, as well as the processing of paper and paperboard. The papermaking industry consumes a large amount of raw materials, water, electricity, and chemical drugs, and generates a large amount of wastewater and waste residue. Therefore, the future of papermaking machinery will develop towards using a wide range of papermaking raw materials, reducing material and energy consumption in the papermaking process, and reducing environmental pollution.

A paper machine is a complete set of equipment that enables the formation of paper pulp into web segments, including a headbox, a web section, a press section, a drying section, a calender, a paper roll machine, as well as host machines such as a transmission section, and auxiliary systems such as steam, water, vacuum, lubrication, and heat recovery. The web part that forms the wet web is the core of a paper machine, so according to the structure of the web part, paper machines can be divided into long web paper machines, sandwich web paper machines, and circular web paper machines.
