FORMING: A sheet of paper begins in the forming section, where a mixture of 99% water and 1% cellulose fiber is introduced evenly across a polyester forming fabric, which acts as both a sheet conveyor and a dewatering device. As the polyester mesh moves, water drains through it, while the fibers and fillers that form the sheet remain on top.

PRESSING: In the press, additional water is mechanically removed from the newly formed sheet. In the simplest press, the sheet is carried continuously by a large polyester mesh between two rolls, where water is squeezed out of the sheet at high pressure.

DRYING: In the dryer section, the paper sheet travels around large-diameter heated cylinders, where the balance of the water is removed by evaporation. Polyester mesh hold the sheet tightly in contact with the cylinders through the dryer section. Constructed of monofilaments, polyester dryer fabric must be heat resistant, rugged, and designed for both drying efficiency and run ability.

PROCESS BELTS: In the press section of today’s new and rebuilt paper machines, a shoe press has replaced the conventional press. The shoe press increases dryness and enhances sheet properties by lengthening the time the sheet is under pressure.
