In June of 2010 a curtain coater had started up on a board machine in Frohnleiten, Austria. It replaced an air knife coater which has been operating in this position. Shortly after start-up the curtain coater showed significantly better quality and runnability than the previous set-up. This paper will discuss quality improvement and energy savings due to reduced drying requirements and improved runnability of the machine.
