Corrugated cardboard longitudinal warpage

June 12, 2022

Controls warping in the vertical direction:

1. Reduce the drag force of the friction plate at the exit of the flyover;

2. Check the overpass pipe guide plate of the control paper gap;

3. If the overpass piles up, the amount of accumulation on the overpass should be reduced;

4. Reduce the brake friction on the preheater;

5. Correct the preheater and idler to allow it to rotate freely;

6. Use base paper with high tension.

Control vertical warpage:

1.Under the influence of paperboard quality, use the base paper with low tension;

2. Increase the pressure of the cotton web on the cardboard to increase the paperboard's force on the hot plate;

3. Reduce preheater brake drag force;

4. Increase the drag force of single-sided corrugated board on the overpass;
