High strength results in a lower number of breaks
The higher the dry content of the paper web after leaving the press section, the less energy has to be expended in subsequent drying. A high initial wet strength of the moist paper web after leaving the press also leads to a lower number of breaks, especially in the first dryer groups. This is essential for good runnability of the entire production facility.
Along with its main task, namely dewatering the paper, the press also has a big influence on the paper’s quality characteristics. It decisively influences thickness and volume, as well as the surface characteristics, of the paper. Along with a high volume, high-quality paper also requires a smooth surface that is identical on both sides.
