OnQ ModuleCoat

OnQ ModuleCoat

Uniform distribution of coating color

OnQ ModuleCoat is a system for coat weight cross profile control in trailing blade coating machines. It ensures uniform distribution of the coating color in machine cross direction.

Cross direction control with OnQ ModuleCoat takes place via adjustment by zones of the profiling device. For this, the actuator is equipped with an incremental and absolute encoder. The additional position feedback via a LVDT (linear variable differential transformer) provides absolute reliability for protection of the profile rail. The auto-mapping function of the Profilmatic control automatically checks the correlation between actuator position and measurement position in the paper web. This allows uniform distribution of the coating color. The “mapping model” adjusts to the measured change.

OnQ ModuleCoat is used in trailing blade coating machines for cross profile control.
