The forming fabric or "wire" of a paper machine is the continuous belt or belts of mesh screen upon which the paper sheet is formed. Most modern forming fabrics are no longer comprised of metal wires. Rather, they are comprised of polyester monofilament. The weave pattern and layering of a forming fabric is designed to meet stringent requirements of dimensional stability, resistance to abrasion (on the wire side), minimum resistance to drainage, minimum wire-mark, and (sometimes) maximization of retention of fiber fines. Traditional Fourdrinier paper machines have a single wire. Modified Fourdriniers and gap formers can have two.

Press felt / paper making felt
There are three series of BOM papermaking felts available in the market. They are single layer base mesh,double layer base mesh and multi layer base mesh. According there structures, they can be divided into BOM formed felt, BOM pressed felt, BOM upper felt, BOM dryer felt, BOM pulp board felt, and so on.
BOM paper-making felts are generally made of the base mesh layer and the fiber layer. The base mesh can be single, double, or multi-layers. The double base mesh
layer can also have a 1+1 laminated. The multi layer base mesh can also be divided into 1+2 or 2+2 laminated. All mesh bases are woven with monofilament or twisted monofilament yarns. The fiber layers are woven with different sizes of polyamide fibers. Fiber layers and base mesh layer are attached by needle stitching to form the felt.
