The Fourdriniermachine is the basis for most modern papermaking, and it has been used in some variation since its conception.
This was a cylinder mould machine, quite different in operation but also developed in England, not a Fourdriniermachine which was not introduced into the USA until 1827.
While the Fourdriniermachine uses a wireconveyor to create the web, another type of machine makes use of a cylinder mold that rotates while partially immersed in a vat of dilute pulp.
The heart of the Fourdriniermachine is an endless belt of wire mesh that moves horizontally.
At the end of the Fourdriniermachine, the paper is slit by revolving cutters and wound on reels.
For example, the Inverform machine, which was invented in England in the 1940s, is a high-speed machine that produces a range of box board used by the food packaging industry.
