Papermaking machines are based on the principles of the Fourdrinier Machine, which uses a specially woven plastic fabric mesh conveyor belt (known as a wire as it was once woven from bronze) in the forming section, where a slurry of fibre (usually wood or other vegetable fibres) is drained to create a continuous paper web.
With processing benefits unlike most synthetic fibers, Eastman Cyphrex flat polyethylene terephthalate (PET) microfibers process well on inclined wire, Rotoformer and Fourdrinier machines.
Las nuevas tecnologias de impresion fueron entonces empujadas por la propia evolucion en los sistemas de formacion de hojas: si para la segunda mitad del XVIII ya existe mencion de las llamadas maquinas redondas espanolas--maquinas que utilizan un cilindro para formar pliegos de papel de manera continua--(figura 7), hacia 1799 se patenta la primera maquina Fourdrinier (mejorada en 1803 por el ingles Donkin) para elaborar papel en bobinas.
The original is now believed lost, hut an engraving of 1743 by Pierre Fourdrinier shows Susan being rowed towards a ship in front of a large fleet gathered off Dover, standing in the prow with her arm outstretched; beneath the picture are reproduced stanzas 4 and 8 of Gay's poem.
Throughout this article it is assumed that the paper structure is isotropic, but most papers produced on papermaking machines such as those based on the principles of the Fourdrinier Machine show a clear anisotropic formation, see also Schaffnit and Dodson (1993), Scharcanski and Dodson (1996, 2000) and Sampson (2009), where the anisotropy of formation is discussed in detail.

John Kay, inventor of an improved weaving shuttle, and the Fourdrinier brothers, inventors of a paper-making machine, were both nearly ruined by the costs of patent litigation.
It depended on all manner of new technologies that moved beyond mere mechanics into the sphere of automation: the science of statistics (the quantification and mapping of "spiritual destitution" for the purposes of extending the "system to every portion of the land"); stereotypography (the ability to copy and store plates for subsequent print runs), steam-powered presses, and the Fourdrinier papermaking machine.

Experiments have been performed on a Fourdrinier pilot paper machine to characterize the behaviour of a Polyethylene Oxide (PEO) and Cofactor (CF) retention aid system under slow wire speed and very low shear conditions.
Forming Fabric Case Study 1: A newsprint machine with a Symformer top-wire forming unit operating at 4150 fpm was able to reduce forming section drive load by replacing the base fourdrinier double-layer fabric with a triple-layer fabric.
