词汇 fourdrinier
词源
fourdrinier. The brothers Fourdrinier, Henry and Sealy, in- vented the fourdrinier machine that makes most of the paper we use. In 1807 they patented the first practical machine for converting wood pulp into paper, but labored 30 years in per- fecting it, aided only by a partial grant from Parliament. The En- glish papermakers revolutionized the industry with their fourdrinier, which is today a huge automatic machine working on the same basic principle but bearing little resemblance to the original.
