Weitmann && Donrad originally designed its rotor damping system for the graphics industry for use in applying a fountain solution to the rools of rotary screen printing machines and for damping fast moving paper webs. More recently, the system has found uses in the textile industry to provide a contact-free and uniform damping of water onto webs and a low add-on application of highly concentrated liqoors with low water content. The system applies solutions and liquid and water suluble dispersions with solid contents that are within tolerances. Two sided application is possible. A central supply unit dispenses the application liquors to the rotors. The types of supply units are the RF-Compact II, RF-Aquapac II, and RF-Aquapac II b.
