A '''paper machine''' (or '''paper-making machine''') is an industrial machine which is used in the [[pulp and paper industry]]
to create [[paper]] in large quantities at high speed. Modern paper-making machines are based on the principles of the Fourdrinier Machine, which uses a moving woven [[mesh]] to create a continuous paper web by filtering out the fibres held in a paper stock and producing a continuously moving wet mat of fibre. This is dried in the machine to produce a strong paper web.

The basic process is an industrialised version of the historical process of hand paper-making, which could not satisfy the demands of developing modern society for large quantities of a printing and writing substrate. The first modern paper machine was invented by [[Louis-Nicolas Robert]] in  France in 1799, and an improved version patented in Britain by [[Henry Fourdrinier|Henry and Sealy Fourdrinier]] in 1806.

The same process is used to produce [[paperboard]] on a paperboard machine.
