Yes, your suspicion is right:
The Fourdrinier process was patented January 18th, 1799 by Louis
Roberts, then sold to Saint-Leger Didot (yes, that Didot family!). Due
to a quarrel between Messrs Robert and Didot, Robert withdrew the patent
but Didot and his nephew John Gamble continued to develop it for the
Fourdrinier brothers, two paper merchants in Paris, in cooperation with
Bryan Donkin. The machine is said to have been in successful operation
somewhere around 1805-1807.
Images of Fourdrinier machines:
The process of making a mouldmade paper, on the other hand, was patented
by John Dickinson in 1809. His patent was based on a machine designed by
Georg Dodd, which originally was built for cutting and placing the paper
produced by the Fourdrinier process.
An image of a cylinder mould machine:
It would be interesting to know why the process of making mouldmade
paper never made it to North America. It seems that the first
Fourdrinier was imported to USA in 1827, and the first US-designed
Fourdrinier built in 1829. No mentioning of cylinder mould machines.
I should also add a correction to my posting yesterday: On a Fourdrinier
machine the fiber/water mixture may also flow out on the mesh, rather
than being sprayed onto the mesh. Mea culpa!
All the best,
