  • PRODUCT DETAIL


Technical Synthetic Fabric -- Press Felt, Forming Screen Belt, Dryer Screen, Single Layer Forming Fabrics- 5 Shaft, Good Dewatering, High Retention


Made by Jurgens 13m Wide Weaving Looms and Austria Automatic Seaming Machine


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.

Polyester forming fabric can be divided into 4-shed, 5-shed, 7-shed, 8-shed, 16-shed and 24-shed based on the weaving structures. And it can also be divided into single layer, double layer, two and a half layer, three layer and SSB triple layer forming fabric based on the categories.
