Curl control

OptiDry Curl, the new solution for curl control, is based on the impingement drying technology. Traditionally dryer groups with a double-felted configuration have been used for controlling the paper curl by adjusting different top/bottom dryer temperatures and affecting in this way drying on the two sides of the paper. Another traditionally used method is moisturizing (with water or steam), which also influences the curl of paper but at the same time increases paper moisture again.

OptiCoat Short Dwell coating | valmet.com

OptiCoat Short Dwell is a blade or rod coater with short dwell time application, especially well-suited for high-speed LWC coating. Short dwell time means that water penetration into base paper is minimized. This enables archieving low coat weights easily.
