Yankee drier profiler and control

Abstract

A coating system, a paper machine, and methods of their use are provided.

What is claimed is: 
     
         1 . A coating system and method thereof to take control and correct the application of the release coating chemistry to insure: the release coating chemistry is at the proper mix ratio as programmed by a recipe set point which may be adjustable by the operator, the release coating is being applied in the proper thickness across the Yankee dryer surface at all times, increase and decrease the proportional valves at each nozzle in order to compensate for, and maintain, a constant flow rate independent from variations in supply pressure, increase and decrease the flow rate in order to compensate for variations in production speed (ft/min), detect and report graphically areas that are not coated properly if the system cannot correct a specific problem, provide a graphical view of the concurrent production as to speed, flow rates, release coating thickness, and Yankee temperature profile over the entire surface, extend the life of the creping and doctor blades, decrease maintenance on the spray nozzles, and translate the production data obtained into clear visual results and warn operators in an audio, and visual (graphical) manner of process problems. 
     
     
         2 . A paper machine substantially as shown and described herein. 
     
     
         3 . A method of operating a paper machine substantially as shown and described herein.
