Process control for spun-lace using machine vision

Measure air permeability and density for SpunLace processes

There is a relationship between air permeability and fabric characteristics such as fabric weight, thickness and density for many non-woven types. Vision systems now seek to provide added value for producers by improving the capability around process control tasks such as formation analysis to enable this.

100% inspection tool for process control

Often it's difficult in high speed manufacturing to get good feedback on what you would consider obvious issues. Opacity measurement, color reflectivity in plastic film processing, textiles, coating variations for converters, formation analysis for non woven inspection and other visual measurements that change during a long run are not normally measured in real time and 100% inspection vision systems usually target defects that are visually obvious, ignoring the slow moving process issues that cost you dearly in the long run.

Adaptive surface inspection improves quality

What is adaptive surface inspection?

Adaptive inspection is the process a vision system can use to update it's segmentation parameters automatically. This is the key to inspecting substrates that have a natural variation in appearance but there is still the requirement to detect low contrast defects.

Block statistics to measure opacity, fiber direction and coating uniformity

Why Block statistics?

We are always looking to build novel measurement tools. The more we learned  about the requirements for measuring opacity, we saw a need for a  tool we called block statistics. We break down the web or sheet into programmable discrete sections and then apply a variety of algorithms that depend on the optical configuration deployed.
