Cracked or split corrugated

In the following illustration, the corrugated fiber is cracked or split, and depending on its severity, the pressure resistance of the board after molding is reduced to varying degrees.

Cause core paper web tension is too large Machine components are not aligned, not on the horizontal surface, causing the edge of the core paper to relax, uneven tension on the core paper is not activated, or the speed is too slow after startup,
Or the pre-conditioner drum is locked and cannot be turned.
The brake tension on the core paper is uneven or too large. The automatic splicer tension is too high for the core paper.
Core paper too dry Paper core paper roll is not round or loose The coefficient of friction is too large, the machine core core paper force is too low, the paper texture is poor Pretreatment lacks pretreatment Pretreatment steam sprayer Use "dry" steam

Measure to check the level or alignment of the base paper tray, pre-processor, and single-side machine. Repair or adjust the drive mechanism. Adjust the brake to reduce the tension on the splicer. `
If necessary, reverse the core paper roll If possible, use a core paper roll. If necessary, reverse the core paper roll. Lubricate with a wax or oil mist. Change the core paper roll
Increase the wrap angle device or steam shower device Instead of using high pressure steam, use reflux steam instead
