Fast and easy root cause analysis of web breaks. The enhanced features provide pulp and papermakers with higher-quality images than before for analysis purposes, enabling them to take virtually instantaneous corrective measures. 

The Valmet IQ Web Monitoring System (IQ WMS) records video images of the crucial events in the process, such as web breaks, tail feeding and defects triggered by the IQ Web Inspection System.

Recorded images are available for playback, enabling operators to quickly find the origin of the event and correct the problem. This shortens downtime after breaks and improves runnability. Optimized machine efficiency delivers fast payback on investment.

IQ Web Monitoring System features:

  • Synchronized recordings as a key for fast and easy root cause analysis
  • Light area adjustment (patent pending) – free rotation of LED light
  • Balanced chain of image handling without losses
  • Web inspection system triggering
  • Automated region of interest analysis with related recordings

Multiple geometries and different wavelengths are available

Unique lighting technology enables the detection of print-critical defects that have not been visible before. More sensitive and reliable defect analysis can be achieved with multigeometry.

The IQ Web Inspection System (IQ WIS) provides new information to reduce the origins of web defects in the effort to optimize production quality and efficiency. The result is a customer product, which meets the highest standards for visual quality, printing performance and high efficiency converting. With the IQ Web Inspection System operators can quickly focus in the specific quality problems, which result in profitability loss. Using this new information the operator can make the necessary changes in the machine operations. Optimized machine efficiency and high product quality deliver fast payback on investment.

Web Inspection System functions:

  • Defect detection with unique lighting technology
  • Integration to WMS for finding the origins of quality problems
  • Real-time defect map with defect viewer
  • Defect classification
  • Periodical defect analysis linked to machine component lengths
  • Defect trend and profile
  • Formation analysis
  • Reel and defect reports
  • Trim planning tools to optimize customer roll quality
  • Automatic target stop control for re-reelers and winders
