After many years of intensive development, Voith Paper has won the first order for a curtain coater used for graphic paper coating in a board machine. This innovative process is being used for the first time for coating applications beyond the field of specialty papers where the curtain coater has been successfully used for years to apply thermo-reactive or capsule coatings.

This new process provides good coverage and superior printability, as well as optimal runnability and significant energy savings.

In this rebuild project, the existing air knife coater was replaced with a curtain coater, allowing the company to overcome the current speed limit and to substantially increase the coating solids content. In this particular case, the coat drying energy costs will almost be halved.

In addition, curtain coating ensures optimal coverage, permitting the use of more cost-effective coating pigments.

The operating window of the curtain coater was successfully widened thanks to efficient process development in the Voith Paper PTC.
