Press Roll

Press rolls help to consolidate the paper sheet by compressing the fibers together. This consolidation helps to enhance the physical properties of the paper, such as stiffness and tensile strength. Press rolls can also be applied for sheet calendering, which involves applying additional pressure to the paper web to improve surface smoothness, gloss, and printability.

Main functions of paper machine press rolls

1. Water removal: The press rolls apply pressure to squeeze out water between the fibers, increasing the dryness of the paper.

2. Sheet consolidation: The pressure applied by the press rolls causes the fibers to bond tightly, leading to improved sheet density and strength.

3. Sheet calendering: The rolls press the fibers, reducing surface roughness and enhancing the uniformity of the paper surface.

4. Moisture control: By adjusting the pressure exerted by the press rolls, the moisture level in the paper web can be regulated.

In summary, paper machine press rolls have various important functions in the paper making line. The rolls play a vital role in determining the final quality, smoothness, strength, and moisture content of the produced paper. Welcome to contact us for details.
