Working principle

The process of paper making line contains the following sections: Wire section, Press section, Dryer section,
Sizing section, Calendering section, Reeling section.

1. Wire section: After the fine pulp come into the headbox, it will be spreaded along the felts on the web end evenly.

2. Press section: To squeeze out as much water as possible in pulp by pressing felts.

3. Dryer section:  Dryer works in group to ensure it can be operated at a gradually slower speed to compensate for paper shrinkage as the paper dries. It will discharge the water content down to a level of about.

4. Sizing section: To improves finished paper’s printing properties and surface bond strength.

5. Calendering section: Calendering can help to make the surface of the paper more sooth and glossy. What’s more, it also can ensure consistent thickness of paper. The pressure given by the rollers applied to the web influences the finish of the paper.

6. Reeling section: To makes the paper more evenly, it can satisfy the needs of various paper. Reel paper into rolls to make it easy to convey and store.
