Line-scan inspection detects defects such as foreign matter, holes, wrinkles and contamination in real time on pulp and base paper production lines, stopping defects early.
This page summarizes a use case published by INTELLIZ. The summary does not state a customer, project status or quantitative results; whether it applies to your product is confirmed with samples and imaging conditions.
Which defects does it check? The summary of this use case describes detecting defects such as foreign matter, holes, wrinkles and contamination in real time with line-scan imaging on pulp and base paper lines, stopping defects early.
How accurate and how fast is it? This use case has no published quantitative results. Missed defects, false rejects and throughput can only be confirmed by testing your samples under your line conditions, against the same criteria.
Why do you need the line speed and web width? For material that runs continuously, speed, width and the smallest defect to find decide the imaging method and the number of cameras. Giving the three values in the same units speeds up the review.
What should I prepare before contacting you? See the information listed above. Including your product, the defects you look for and your production conditions in the inquiry helps us start the review.
Consumer Goods, Plastic & Containers
Surface Defect
Inline Inspection
Continuous Material (Film/Paper/Coil)
Defects this use case covers: Foreign matter, Holes, Wrinkles, Contamination
Covers defects visible on the paper surface (foreign matter, holes, wrinkles, contamination and the like).
Quality items that surface imaging cannot measure, such as basis weight, thickness or moisture, need other measuring methods.
According to the use case summary, defects are detected in real time with line-scan imaging. The actual camera setup is decided by web width and line speed.
