Valmet Coater Roll Cover CC
Valmet's roll cover product portfolio also includes a polyurethane cover as alternative for rubber covers for blade coaters. As hard-coated coater blades have become increasingly common, problems have emerged with the durability of traditionally used rubber covers, particularly in the edge areas where the roll cover and the abrasive blade come into contact. The durableValmet Coater Roll Cover CCprovides a solution to this issue multiplying running time in the blade coater, reducing the need for roll replacement and grinding.
Results with Coater Roll Cover CC
- Longer regrinding intervals, reducing the need for roll replacement
- Less profile wear thus less material removed during grinding, resulting in longer cover lifetime
- Uniform hardness profile and stable roughness profile resulting in smoother coating profiles
- Superior impact resistance during web breaks reducing roll cover marking and damages
