Sun Hong Paper Machine Clothing -- Forming Fabric

Forming Fabric is a mesh fabric installed in the forming part of a paper machine, used for dewatering pulp and initially forming paper sheets. Its main function is to evenly deposit the pulp and form initial wet paper sheets through its own support and water filtration ability after the pulp enters the mesh. Modern paper machines are characterized by high-speed and continuous operation, which places extremely high demands on the structural strength, breathability, wear resistance, and stability of the forming fabric.The forming fabric not only affects the dewatering efficiency of the pulp, but also directly determines the surface quality, structural uniformity, and fiber arrangement of the finished paper, and is therefore known as the "shaper of paper quality".

As one of Sun Hong's best selling products, forming fabric has many years of production experience and can provide you with the most competitive prices and the most professional technical support, and can customize professional integrated services for you according to your needs.

Production Process

FAQs about Forming Fabric

What is the reason for the rapid wear of the edge of the forming fabric?

Most of the most serious wear is at the joint between the vacuum and the non-vacuum, about 10-15cm from the edge of the forming fabric. At this time, it is necessary to increase the width of the vacuum box opening, add normal pressure lubricating water to the edge of the vacuum box, or apply reinforcing ribs at appropriate locations.
Why does the forming fabric produce delayed wear?

Hysteresis wear is caused by the running speed of the forming fabric being lower than the surface of the dewatering elements and other devices in contact with it. It usually occurs at the couch roll or drive roll.
How to deal with the forming fabric when the paper machine is shut down?

If the shutdown time is short, on a paper machine with low load and low pulp temperature, the original operating tension value can be retained;
If it is on a high-speed paper machine with high load and high temperature, even if it is shut down for a short time (the fourdrinier paper machine is at creeping speed), the tension must be relaxed;
If the machine is shut down for a long time, all tensions need to be relaxed and the forming fabric needs to be stored without tension. It can also be washed and unrolled for storage.
What should be paid attention to when using the forming fabric in normal times?

When the paper machine is shut down, turn off the vacuum water suction device to avoid partial sinking of the forming fabric and accelerating the wear and wrinkling of the forming fabric. Turn off the high-pressure water at the same time to avoid partial sinking of the forming fabric and accelerating the wear and wrinkling of the net.
What should be paid attention to before installing the forming fabric?

Before starting the machine, it is necessary to check and remove foreign objects on the forming fabric and the automatic net guide system according to the direction of the arrow on the forming fabric.
