    Abstract: A method and a system are disclosed for detecting the features of a water layer in layered enclosures of single unit dose products. Thanks to the method and the system of the invention, the layered enclosures may be manufactured to higher specifications and quality owing to real time control of the features of the water layer between the enclosure layers. The technical advantage of the method of the invention consists in the possibility to detect the features after formation of the layered enclosure is complete—hence inspecting the finished product—and to feed back the detected information to the very water laying device for a real time adjustment of the features of the water layer at the areas where acceptance criteria are not met.

    Abstract: A method of analysing the quality of a welding area of an absorbent sanitary article is disclosed. During a learning step, a plurality of welding operations are performed both with a sufficient quality and with an insufficient quality, and the welding area generated for each welding operation is monitored via a camera. During a training step, the pixel data of the welding areas monitored during the learning step is processed for training a classifier configured to estimate a welding quality as a function of respective pixel data of a respective welding area. Accordingly, during a normal welding operating step, the welding quality may be estimate via the classifier, thereby improving the environmental sustainability of the production process.
