Working principle

1.  Corrugated paper machinery contains the following sections: Forming, Pressing, Drying, Calendering, Rewinding.

2.  Web end: While the fine pulp enters into the headbox, it will be spreaded along the felts on the web end evenly.

3. Press section: The water in pulp can be squeezed out as much as possible by pressing felts with press roll.

4. Dryer section: Dryers works in group to ensure it can be operate 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 6%.

5. Calender section: Calendering helps to make the surface of the paper more sooth and glossy. What’s more, to ensure consistent thickness of paper.

6. Coating: Sizing improves the paper’s water resistance, printing properties and surface bond strength.

7. Rewinding section: Shape sheet into rolls to make it easier for shipping and conveying, and use slitter to cut the product into multiple strips.
