B Flute Hard Chrome Plated High Speed Traditional Corrugating Roll
Flute Profile
Almost every set of corrugating rolls are needed to be designed and
customized separately according to the width, diameter, flute
height, corrugated paper GSM, speed and cardboard physical index
requirement.

Adjust well
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.
