3/5/7 Ply Corrugated Cardboard Production Line


This production line is available in large amount automatic production, which can produce corrugated paperboard correspond to national standard with high quality, and adopted concentrated control, operated and repaired easily, safely, reliable, reducing manpower, This production line adopts international energy saving technology with oil heating, which can saving 40 percents energy than steam heating, So this can reduce costs effectively. It’s an economical production in big, middle paperboard company.

1. Total Length: 40-70m

2. Total Power: 100-200kw

3. Two kind of frame with shaft and frame without shaft, provide the customer with the choice.

4. Corrugated paperboard marching: diameter of corrugated rouer: 280-406mm, electric adjust speed motor used.

5. Double cylinder gum mounting marchine: On the adoption, inside two layers draw the gun, dascend to carry the paper lead the paper roller.

6. Oven: total length 7.8m, combined with 9-18 heating flocks.

7. Setting Part: total length 3.8-5 m, combined weith some pairs of symmetrical shafts.

8. Horizontal, Lengthuays slicing marchine: Common knife or superthin knife selected based on customer’s demand,high automatically, handy operating.
