Press Felt

Before installing felt on the machine, you need to pay attention to the integrity of the packaging, check if there is any damage, and then check if the specifications on the marker are consistent with the goods ordered (specification, amount, contract etc.).And then make sure there is no problem with the appearance, dimension and material.

When install the felt, pay attention to cleaning the installation area of the paper machine. Identify the front and back side and the direction of operation (the side with felt NO and SH (Sun Hong) is the front side. The direction of operation is indicated by the arrow). Do not damage the felt by pulling, tugging. Take care to prevent the press felt from being stained or damaged by hard objects.

Make preparations in advance. Before releasing the pulp,you can stretch the felt firstly, but do not make it over-tensioned. If it is over-stretched, the press felt will shrink horizontally, resulting in deformation of the base cloth eyelet and making water filtration problematic.
Make sure that the vacuum and washing system can operate normally. Observe the standard line running and deformation of the felts and adjust them as soon as you find any problems.

1. Take care not to damage the press felt artificially and avoid cutting. To prevent wear and tear of the press felt, wash it evenly.
2. Try your best to avoid foreign objects entering the pressing zone.
Clean the felt regularly and pay attention to the norms when using chemical detergents.
3. When the machine is offline for 4-5 hours or more, the felt should be cleaned and allowed to relax.
4. To prolong the life of your press felt, you need to wash it regularly. Washing is the key to a longer life and less paper problems.

1. A period of idling facilitates the initial adaptation of felt and to extend its lifespan.

2. After a period of idling, new felts can be washed off the objects on surface, improve the smoothness of the surface
It helps to remove oil and dirt,also to improve its density and air permeability.

3. After installing the new felts you can apply some pressure when felt running, add hot water close to 50°C, then 5% alkaline water to soften the press felt, and pass 0.1 Mpa steam into the dryer cylinder to shorten the initial adaptation time.
