WebbIn this set-up, one roller is a metering device as well as an application device. More precise control is achieved by the addition of more rollers. Three-roll Coating. Three-roll coating uses a metering roller, an applicator roller and a backup roller. Common three-roll configurations are nip feed coating and L-head coating. http://glasslaminatingsolutions.kuraray.com/fileadmin/user_upload/technical_information/downloads/Butacite_G-2014_NEW.pdf
