A Fourdrinier is a type of forming section or former on a paper or board machine. It serves three main functions: to drain and recover white water from the stock suspension to form a sheet, to deliver the formed sheet to the press section at the highest possible consistency, and to optimize sheet formation to create a strong, uniform, high quality sheet of paper or board. Knowing the design and principles of the Fourdrinier is essential to proper sheet formation.
