Air Coupled Ultrasonic Guided Wave Measurement for Board Crease Integrity
Air-coupled ultrasonic guided waves quantify paperboard crease ply delamination and micro-cracking non-destructively, preventing box compression failure.
Web Inspection
Continuous Monitoring
Automated scanning systems designed to identify surface defects and irregularities on a moving roll of paper or film ensure consistent quality during production. Modern web inspection utilizes high speed cameras and specialized lighting to view the material as it travels through the press or winder. The system identifies holes, spots, slime streaks and coating skips that are invisible to the human eye at high velocities.
This technology prevents defective material from reaching the final customer.
Defect Detection
Sophisticated algorithms classify each found defect based on its size and shape. During web inspection, the software records the exact location of every flaw and generates a digital map of the entire reel. This map allows the finishing department to stop the winder and remove the contaminated sections.
Real time alerts allow operators to adjust the machine settings immediately if a recurring problem appears.
Data Integration
Resolution of the imaging sensors determines the smallest particle that the system can reliably detect. High performance web inspection setups use multiple camera banks to cover the full width of the web without gaps. The integration of this data into a mill-wide quality management system provides a long term view of machine performance.
Light sources are often tuned to specific wavelengths to highlight flaws in transparent films or highly reflective foils. This continuous oversight reduces waste and improves the yield of sellable products.
