For many years, book paper has been an important part of the paper industry. Nowadays, the continuous growth of the production capacity of book paper has become a reality through new technologies that can satisfy the quality of products. The development of multi-layer headboxes provides an opportunity for the simultaneous use of different virgin fibers and secondary fibers in the production of sheet paper, making the final product versatile. In a multilayer headbox, two or three layers of fibers are typically combined to form a single paper layer.

 

In addition to the use of a multi-layer headbox, the concentration dilution distribution technique can reduce the quantitative change in the sheet. This technology makes it easy to retrofit existing paper machines. Especially for the multi-layer headbox, using the concentration dilution distribution technology, the quantitative distribution change can be reduced from 2.0 to 2.5% to 1%. Reduce the fluctuation of paper count and copy out uniform paper sheets.

 

When Voith Sulzer and Andritz collaborated on the development of new tissue paper technology, the TissueFlex technology was introduced, which introduced NipcoFlex shoe press technology into the production of sheet paper.
 

 

The nip pressure distribution of the shoe press is wider than the vacuum press roll, allowing it to produce the same line pressure at a lower maximum nip pressure. In conventional vacuum presses, it may happen that the sheet is wet at the press exit. This rewetting phenomenon will result in a 10% loss in dryness of the sheet, while the pressure at the exit of the shoe press is rapidly reduced, resulting in a small amount of moisture return to the sheet.

 

This shoe press maintains the same dryness and good bulk of the produced tissue paper. It is said that the shoe press can be used to increase the bulk of the paper by 15 to 30% in the vacuum press position with a universal Yankee dryer, but the tensile strength may decrease slightly.
