Differences between seamed press felt and endless felts

The biggest difference between seamed press felt and ordinary press felts is installation and disassembly. Seamed press felts are specially designed with seam structures. Ordinary press felts require complex installation and disassembly by humans, which takes a lot of time and manpower. Seamed press felts can be directly put on the paper machine and connected using a special seam structure, which not only ensures the safety of the production process but also greatly reduces the replacement time so that the paper machine can be put into production quickly.

Easy to install, reduce labor consumption, reduce downtime and improve efficiency.

Stable structure, excellent pressure resistance and tensile resistance.

Good water filtration performance.

Sun hong's seamed press felts are made of high quality fiber materials and designed using special processes.

The seams are reinforced so that there is no need to worry about falling off even when running at high speeds, which effectively improves your production efficiency.

We can customize and tailor a unique solution for you according to customer needs.

Things you need to know about felt lint ? Why and How to slove it ?

Reason:There are many reasons for the damage and the lint of the felt, mainly two of which are scraped by machine parts and chemical damage.1.The most common reason is that the surface of the press felt torn loosened by high pressure water.2.Lack of lubricating water between the vacuum panel and the

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.
How to get the price of press felt?

Please provide us with the following information:your paper machine speed, paper kind, paper weight and the size of the felt(W*L*GSM)
What are the causes of press felt lint?

There are many reasons for the damage and the lint of the felt, mainly two of which are scraped by machine parts and chemical damage. The most common is that the surface of the press felt torn loosened by high pressure water.Sometimes the responsibility is not with the fabric, because the fibers can also come from pulp or even from outside systems.
What causes the standard thread of press felt to run off or bend and deform in front and back?

①The length of both sides of the press felt is not the same
②The paper machine rollers are not parallel, causing the press felt to be unevenly tightened
③Uneven watering of the press felt when restarting the machine, resulting in inconsistent shrinkage of the press felt.
What should I do if the press felt becomes wider after use?

The press felt may become wider after a period of use, which is normal. Don't tear it by hand, you should stop machine and cut off the extra edge after it is dry, then use a soldering iron to iron the edge.
What should we pay attention to when changing a new felt?

Distinguish the front and back side of the felts.

Install according to the standard line on the felt
