One of the most important steps in paper production is surface sizing, because the hydrophobicity of the paper surface is crucial for the subsequent print image or even water resistance. In most cases, this key performance property of paper is adjusted exclusively with a surface sizing agent.

There are often problems with increased Cobb values occurring when using surface sizing , which can only be slightly improved with an additional dosage of surface sizing agent. A second  adjusting screw  would be desirable to solve this problem.
