Fourdrinier machineMachine for producing paper, paperboard, and other fibreboards, consisting of a moving endless belt of wire or plastic screen that receives a mixture of pulp and water and allows excess water to drain off, forming a continuous sheet for further drying by suction, pressure, and heat. Calendering smooths the paper or board and imparts gloss or other desired finish to the surface. The first machine to produce a continuous web (roll), the Fourdrinier machine was patented in France in 1799 by Louis Robert and later improved in England by Henry (1766–1854) and Sealy (died 1847) Fourdrinier. With further improvements over the years, it is still in use today. Fourdrinier machine [‚for·drə′nir mə‚shēn] (mechanical engineering) A papermaking machine; a paper web is formed on an endless wire screen; the screen passes through presses and over dryers to the calenders and reels.

Internal Size: A fourdrinier machine producing lightweight specialty printing and writing papers was alkaline sized with AKD and used a bentonite microparticulate retention system. The new three-ply paper fourdrinier machine will use state-of-the-art technology to produce a strong, yet light-weight sheet of paper. There still are many excellent high-tech products directed to improving sheet quality and machine operations for cylinder and fourdrinier machines, but new technology in these areas in the future will most likely come from smaller suppliers. |
