Double Layer Wires Carton Paper Machine, mainly used for making testliner cardboard paper, corrugated body paper. Paper machine line is mainly divided into several parts as below: Head Box, Fourdrinier Section, Press Section, Front drying section, Inclined type Surface Sizing Machine, Back Drying Section, Calendering Section, Reeling Section.

 

Every Parts Function

 

1. Head box: Two sets open type Head Boxes, respectively correspond to top layer wire, bottom layer wire, By controlling the liquid level in Head Box to control and stabilize the sizing pressure head of feed pulp.Flow pulp, make the stock uniform spread on the wire.

 

2. Wire part: Double layer wires, respectively correspond to top layer wire, bottom layer wire. Pulp initially dehydration, reduce the following burden.

 

3. Press Section: Divided into 1st press, 2nd press. 1st and 2nd press are MG press.  Squeeze dewatering, improve the paper tightness.

 

4. Front Drying Section: Φ1500/Φ1800 Dryer, group drive. Removing the water of paper.

 

5. Inclined type Surface Sizing Machine: Increase the paper’s physical properties.

 

6. Back Drying Section: Φ1500/Φ1800 Dryer, group drive, paper dehydration again after sizing.

 

7. Calendering Part: Double Rolls Calender, Upper and Lower Roll are metal roll, improve paper’s smoothness, get higher quality paper.

 

8. Reeling Part: Pneumatic Horizontal Rolling Machine,  make paper get certain length and breadth.
