Pressure roll is beneath the corrugating roll. It exerts pressure upon the lower corrugating roll, which sticks the cardboard paper and the top of the corrugating roll tightly. Because of the direct touch between the surface of pressure roll and cardboard paper, the surface of pressure roll should be cleaned frequently.
Our pressure roll can be regrind 3-4 times because of it's deeper harden layer and thicker barrel thickness. We will design appropriate crown to match with corrugating rolls. That's one of key points for a good quality paperboard.
