Tungsten Carbide B flute Corrugated Roller for Corrugated Cartons
Flute profile
The special flute design from Meijia:
The same meter of single corrugated board can be saved up to 5‰.
The volume of glue can be saved up to 5‰ thanks to a better lamination between fluting paper and linerboard.
The following table is just for a reference.

How to adjust the corrugating rolls well to expand the lifetime?
1. Inspect the balance of corrugating roll regularly, at least once a month.
2. Inspect the gap among corrugating roll, glue roll and pressure roll to avoid abrasion.
3. When installing corrugating rolls, mind the small gap between corrugating rolls and suction hood which will cause abrasion of corrugating rolls and aluminum plate from suction hood.
4. The copper knives will loosen with the movement of machine. The knife in “T” position will scratch the coating on two sides of grooves. So fix the cooper knives regularly.
5. In the premise of assuring corrugated board quality in real production, it’s better to use smallest oil/air cylinder pressure both of corrugating roll and pressure roll.
6. When changing wide width to small width in real production, reduce oil/air cylinder pressure both of corrugating roll and pressure roll accordingly to avoid abnormal abrasion caused by excessive pressure. Especially the direct abrasion between corrugating rolls and pressure roll in paperless areas will cause falling off of coatings.
