Back-up roll coater systems
Our color coating lines feature extremely precise and reliable back-up roll coaters. What's standard procedure here is that the top side of the strip is coated by one of two coater decks with three rolls. This means you can change colors and coatings fast Expressed simply: you just set the rolls to the thickness you require. It takes only one coater deck with two or three rolls to coat the bottom surface with the same coating.
To prevent vibrations, our coaters are very rigid. What also counts is that the precise roll adjustment and roll drives ensure even coating. Installed here is a wiper system that continuously cleans the back-up roll. You can use the hydraulic quick retraction mode to open and close the coating rolls within two seconds to allow the strip joint to pass through.
Vertical roll coater
It's necessary before color coating to apply a passivation coating to the strip surface. This happens in a vertical roll coater. Our effective control system ensures a uniform coating in the required thickness at low media consumption. Also featured in our coaters are several circulation systems for quickly changing the coating media. You hardly have to wait at all because the rollers, pans and media systems are cleaned automatically in less than two minutes.
