Functionality

The applicator roll brings the water/liquid from the pan to the metering nip. The ­hydrophilic transfer roll meters the media to the web, with or against the web ­direction. The transferred amount of coating/media is controlled by the speed of the hydrophilic roll, that is, increased velocity results in an increased applied amount.
