Shoe press felt description
A shoe press consists of a shoe press roll and a counter roll which can be a solid roll or, for higher speeds and wider machines, a deflection-compensated roll. A separate load joint between the bearing housings of the shoe roll and the counter roll carries the linear load of the shoe press. Shoe press felt is used here.
Shoe press felt features
1. High anti-compaction capacity.
2. Extremely high elasticity and recoverability.
3. Strong drainability and larger void volume.
4. Long holding time of wear resistance and plastic strength of felt.
5. Smooth felt surface and even pressure distribution.
Shoe press felt working principle
A paper transporting felt for a shoe press includes a base layer, a first batt layer which is formed on a wet paper side surface of the base layer, a second batt layer which is formed on a roll side surface or a shoe side surface of the base layer, and a wet paper contacting fibrous layer which includes split fibers and is formed on a wet paper side surface of the first batt layer so as to come into direct contact with the wet paper. The split fibers are split by being pressurized by the roll and the shoe.
