The felt roller is an important part of the paper machine wire section, mainly used to support the forming wire surface and help dehydration.
The felt roller is usually made of a metal roller covered with rubber, the purpose is to make the roller elastic, play the role of paper peeling, easing the pressure of the pressure roller on the wet paper and felt, and protecting the felt to extend its service life.
1.Support and support
As part of the paper machine, the felt roller is mainly used to support and support the mesh surface to ensure that the mesh surface can run smoothly without tilting or other forms of instability. This is crucial for the formation of paper sheets and subsequent processing steps.
2.Transmitting driving power or running tension
The felt roller is also responsible for transmitting driving power or running tension to ensure that the mesh surface can move at the expected speed and force. This is very important for maintaining stability and uniformity during the paper sheet formation process.
3.Produce dehydration and provide drainage and water storage space
The felt roller can help remove excess water from the paper sheet and accelerate the paper sheet formation process by slightly pressing the mesh surface. At the same time, they also provide drainage and water storage space, so that the paper sheet can pass through the subsequent processing steps smoothly in a wet state.
4.Leading the paper sheet peeling and safe paper guiding
During the papermaking process, the felt roller also needs to guide the paper sheet to peel off the mesh and ensure the safety of this process. By accurately controlling the movement trajectory and force of the felt roller, it is possible to effectively avoid the paper sheet from being damaged or other quality problems during the peeling process.
5.Effects that affect the forming uniformity and the surface properties of the paper
The working state of the felt roller directly affects the forming quality and surface properties of the paper. By adjusting the hardness and elasticity of the felt roller, the texture and smoothness of the paper surface can be controlled to meet the needs of different types of paper.
6.Stretching effect
During the paper forming process, the felt roller also helps to stretch the mesh surface so that the fibers are more evenly distributed on the paper. This not only improves the quality of the paper, but also helps to reduce waste in subsequent processing.
