Automated testing ensures process reliability and consistent quality in cartonboard production
NEWS
Mayen, March 6th, 2026 – With the introduction of an automated testing system, WEIG has further advanced its quality monitoring: higher testing density, faster availability of measurement results, and comparable quality data both within the Mayen mill and across sites with Annweiler.
The Autoline testing line provides reliable quality results in a very short time. Thanks to automated measurement, several tests can be performed in parallel. As a result, our quality assurance experts can detect deviations earlier and initiate corrective actions within the ongoing production process when necessary.
This significantly increases the number of available measurement points, allowing not only individual values but complete quality profiles to be recorded. The result is more uniform quality across the entire web width and improved transparency regarding potential fluctuations.
The testing line measures, among others, the following parameters:
- Whiteness
- Bending stiffness
- Thickness
- Smoothness
- Grammage
- Gloss
Another advantage of the new system is the high accuracy and consistency of the measurement results. Because the testing process is standardized and reproducible, measurement errors and variations between individual test cycles are significantly reduced. This effect also applies across sites, as identical systems are installed at our cartonboard mill in Annweiler. As a result, a consistent, cross-site evaluation of product quality is ensured.
By integrating this testing technology, WEIG is strengthening its inline quality monitoring and creating the foundation for even more stable, comparable, and traceable product quality during the ongoing production process.
