Web inspection for quality optimization in pulp and paper

For papermakers looking to optimize product quality, ABB’s Web Imaging System (WIS) and Web Monitoring System (WMS) provide the most advanced sheet detection capability on the market.  

Mill challenges that web inspection can help address: 
  • How to calculate roll-specific quality values to automatically classify rolls before they reach the winder?
  • How to trace wrinkles, dirt or defects back to their root cause so remedial action can be taken?
  • How to avoid losing value and decreasing profit potential due to quality issues and reprocessing?
  • How to reduce or eliminate downtime caused by sheet breaks and defects?
Accurate web defect detection, imaging, and identification all play crucial roles in automation, quality control, root cause tracing and process improvement. With 40+ years of superior web inspection experience, you can rest assured that ABB’s solutions offer you state-of-the-art tools for identification of web defects, enabling quick corrective actions.

PLEASE NOTE: ABB is ending the active sale of both the Web Imaging System (WIS) and Web Monitoring System (WMS). ABB is fully committed to support the existing systems in line with our full lifecycle policy. If you have questions, please contact us ABB Pulp and Paper
