The purpose of adding medium height to rubber roll is as follows.A. Correcting the deflection of the rubber roller body during operation (making it equal contact with the compressive material)B. Optimum linear passage of cloth, wood, paper, etc. (to prevent snaking or bending)It is widely used in the production process with large length-diameter ratio (L/D, cot surface length/cot diameter) or high pressure.Medium and high speciesMedium and high species. jpg2. Medium and high accuracyMedium and high accuracy varies with length-diameter ratio of cots, type of rubber layer, thickness of rubber layer, working condition, medium and high processing capacity and hardness of rubber layer. Generally, the medium and high processing capacity is less than 0.05 mm.
