These controls use model-based algorithms to improve the speed and accuracy of machine direction variables, resulting in greater product uniformity, minimized process upsets, and efficient raw material usage. ABB's machine-direction controls are part of a complete, integrated quality control solution.
ABB controls are the fastest and most accurate in the industry using an advanced, time-based Kalman filtering technique for process scanning measurement. This technique extracts precise MD information from scanning online sensors housed in ABB's scanner. Since ABB scanners never leave the sheet, ABB MD controls receive accurate and continuous online product information for better overall performance.
Machine Direction Controls include:
- Weight Controls
- Moisture Controls
- Ash Controls
- Opacity Controls
- Coat Weight Controls
- Automatic Grade Controls
- Color Controls
- Automatic Shade Change Controls
