“Wet Line” a natural phenomenon, occurs during paper production. It needs to be carefully monitored to avoid losses and expensive breaks in production.

As described in the US patent number US4500968A, the wet line is the line of demarcation between the portion of the stock on the paper machine wire submerged in water and the portion having fibers extending above the depth of the water. Looking down at an acute angle to the wire on a paper machine as it is running one can see the glossy area where the water extends above the surface of the stock and a matte area […]where sufficient water has drained through the stock.

“Wet Line” can be monitored 24/7 with byteLAKE’s Cognitive Services. A dedicated module, designed for exactly that purpose.

To automate that process, byteLAKE has worked with the leaders in the paper industry to further optimize byteLAKE’s Cognitive Services for the purpose of automated wet line detection. The solution is visualized in the picture below.

“Wet Line” detection with Computer Vision

byteLAKE’s Cognitive Services for “Wet Line” detection has already been commercialized and successfully deployed in paper mills.

We have already successfully deployed byteLAKE’s Cognitive Services in commercial environments. Our clients leverage our AI models to streamline quality monitoring and bring AI-powered automation into various processes. The goal of these projects has mostly been to support our clients’ staff in quality monitoring efforts and eventually increase the overall effectiveness of the production processes. And in the case of the “Wet Line Detector”, to help them improve the paper production process specifically and make it more efficient.

Paper Production monitoring with Artificial Intelligence

Humans and machines both make mistakes. Therefore, byteLAKE’s Cognitive Services have been designed to effectively bring out the best of both worlds.

byteLAKE continues collaboration with the industry leaders to develop further modules within the Cognitive Services offering as Artificial Intelligence has a huge potential for manufacturing automation and quickly delivers measurable benefits.

About byteLAKE’s Cognitive Services

byteLAKE’s Cognitive Services is a collection of AI models designed to address Industry 4.0 needs. Each AI model we designed and trained is razor-focused on specific industry tasks, therefore ensuring maximum accuracy. In essence, byteLAKE’s Cognitive Services focus primarily on the following two areas:

There are a couple of special versions of Cognitive Services:

  • Wet Line Detector for Paper Mills: automates detection and measurements of the so-called wet line which occurs during paper production. This module helps reduce costs, expedite visual inspection and avoid unplanned downtime in paper mills. Available as a complete end-to-end solution, including edge components (hardware computing units, cameras), software license, integration services or guidelines, and post-deployment customer care.
