a paper-making machine where the paper is made by pulp draining through a continuous wire mesh. ➮ twin-wire fourdrinier

COMMENT: The machine was patented by Henry Fourdrinier before 1810. In it, the white pulp enters from a vat at one end, and flows forward along the mesh becoming paper as the water drains away. It is then dried on heated cylinders. Fourdrinier machines produce webs of paper and can be adjusted to produce different thicknesses, weights and finishes.
