  • Preset control, feed forward control and feedback control can be appropriately combined together to realize precise coating weight control.
  • Dispersions in the dose can be reduced, when coil is exchanged and coating or speeds are changed. Moreover, in case of changes in the control environment due to an exchange of nozzles or similar reasons, adaptation control can be used to minimize any decline in precision.
  • The system comes equipped with automatic tuning capability for a model to predict coating weight and a function to analyze the coating profile in the direction of strip width, thereby supporting precise control.
