At the time Robert was working for Saint-Léger Didot, with whom he quarreled over the ownership of the invention. While still on the fabric in the sheet mould, the wet paper is pressed to remove excess water and then the sheet is lifted off to be hung over a rope or wooden rod to air dry.Fourdrinier machineIn 1799, Louis-Nicolas Robert of Essonnes, France, was granted a patent for a continuous paper making machine. Extra nips give more smoothing but at some expense to paper strength.Reel section where paper coming out of the machine is wound onto individual spools for further processing.There can also be a coating section to modify the surface characteristics with coatings such as china clay.HistoryBefore the invention of continuous paper making, paper was made in individual sheets by stirring a container of pulp slurry and either pouring it into a fabric sieve called a sheet mould or dipping and lifting the sheet mould from the vat. Only one nip (where the sheet is pressed between two rolls) is necessary in order to hold the sheet, which shrinks through the drying section and is held in tension between the press section (or breaker stack if used) and the calender. Infra-red driers are also used to supplement cylinder drying where required.Calender section where the dried paper is smoothened under high loading and pressure. Drying removes the water content down to a level of about 6%, where it will remain at typical indoor atmospheric conditions.

The first modern paper machine was invented in Britain by Henry and Sealy Fourdrinier, and patented in 1806.The same process is used to produce paperboard on a paperboard machine.Contents1 The process sections2 History2.1 Fourdrinier machine2.2 Similar designs2.3 Related inventions3 Pulp types and their preparations4 Stock (pulp) preparation5 Operation5.1 Forming section or wet end5.2 Variations of the Fourdrinier forming section5.3 Press section5.4 Dryer section5.5 Sizer5.6 Calender section5.7 Reel section5.8 Winder section6 Glossary7 Materials8 See also9 Notes10 References11 External linksThe process sectionsPaper machines usually have at least five distinct operational sections:Forming section, commonly called the wet end, is a continuous rotating wire mesh which removes water from the paper by sucking it out of suspension.Press section where the wet fibre web passes between large rolls loaded under high pressure to squeeze out as much water as possible.Drying section, where the pressed sheet passes partly around, in a serpentine manner, a series of steam heated drying cylinders. 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. 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.
