The forming section consists of a long moving belt of fine mesh screen supported by rolls or foils. For many decades, this screen belt was made of bronze and called the “wire.” Today it is made of synthetic polymer — primarily polyester monofilament — and is called the forming fabric. Newer machines (gap formers) trap the slurry out of the slice between two forming fabrics. As the forming fabric moves along the forming section, water drainage is assisted by foils. The fiber then passes over the suction boxes to pull more water from the furnish. Still more water is removed at the couch roll just before the sheet leaves the forming section. At this point, the sheet consistency is about 20%.
Dedicated research has produced synthetic forming fabrics that yield improved drainage, higher production and longer life at a lower cost per ton of paper produced.
Keylife’s forming fabrics are available in a wide variety of meshes, depending on the type of paper produced. Coarse mesh fabrics are used to manufacture heavy paper grades such as those used in the production of corrugated boxes. Very fine mesh fabrics are required for lightweight paper, such as writing paper, book paper and magazine paper. The average life span of a forming fabric, depending on the type of paper, is approximately three months.
Single Layer Forming Fabric is usually used in slow or medium speed paper machine. Although its structure is simple, it has a uniform mesh, a fine surface, high fiber supporting index, good dewatering, light fabric mark and a high fiber retention.
