Product Description

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.

Forming fabric is a very important for a paper machine in a paper mill. In general formation of paper depends on wire cloth and refining of paper pulp. Paper machine wire cloth (forming fabric) made from polyester or polyamide monofilaments. To shape an uninterrupted belt, it is made by endless of a seam. During woven of forming fabric, filaments are composed of paper machine direction and paper machine cross direction. The filaments of paper machine direction or lengthwise are called warp. One the other hand the filaments of paper machine cross direction are called weft or Shute or filling. The construction of wire cloth depends on some weaving variables such as pattern, mesh, yarn, diameter, degree of crimping etc. Mesh is very important for a wire cloth (forming fabric). Water drainage and retain of fibers are depends on it.

According to the category, forming fabric can be divided into single layer wire cloth, 1.5 layer wire cloth, double layer wire cloth, two and a half layer wire cloth, triple layer wire cloth and 3.5 layer wire cloth.

In accordance with weaving, wire cloth (forming fabric) can be divided into 2-shed, 4-shed, 5-shed, 7-shed, 8-shed, 16-shed, 24-shed etc. A paper machine wire cloth has two surfaces. One is the forming surface or top surface and another is the wearing surface or underside surface.
Depending on paper machine and various paper grades wire cloth also difference. The uses of triple layer wire cloth (forming fabric) is increasing day by day.

FAQ

How to choose the right forming fabric for your paper machine?

Forming fabric design based on different machine type, operation speed, paper grade. So please provide us your paper machine information as details as possible.

How to Install Forming fabric

1. Before installing the forming wire, kindly check the equipment if it is in good condition, the surface of wires should be forbidden from unevenness, slanting, burr, sand, etc.

2. The running direction must be in accordance with the direction of the arrow on the wire, the wire should be placed in the correct position, and the rollers should be paralleled with each other to prevent the wires from being deflected.

3. There should be a swinging high-pressure water device that used to wash wire. Water pressure is not lower than 6-10 kg/cm² for the medium and low-speed paper machine; speed more than 350m/min, water pressure is not lower than 10-15 kg/cm²; When using multi-layer forming wire, water pressure is not lower than 15-30 kg/cm², meanwhile water should be clean and without sand.

4. When installing the forming wire, firstly let the wire be slightly tensioned, add water to lubricate the operation, adjust the tension to normal after sizing, keep the tension of the low-speed paper machine at 3-4 kg/cm², and high speed one at 4-6 kg/cm².

Packing & Shipping
