CNC Regularised Parabolic Crowning For Pressure Rolls
Pressure roll is designed to apply pressure across the full corrugated web to ensure consistency of the lines and fluted medium in the single Facer.
Pressure roll is beneath the Corrugating rolls because if there is direct touch with the surface of roll and paper the surface of the roll should be cleaned on regular basis .
It can be re worked 3-4 times because of it’s thickness and hardened layer .
The Technical Name Is The Cosine Curve. This Parabolic Shape Will Compensate For Deflection In Nip Rolls Or Long Rolls .
In order to maintain the pressure balance the roller should also have convexity.
