Integrated quality assurance for nonwovens

Based on the know-how of EVS, a high-technology supplier of automated vision inspection, acquired by Uster in 2018, the Uster EVS Fabriq Vision N ensures consistently high rates of defect detection to guarantee quality. This is achieved by using automated control during intermediate inspection. Uster EVS Fabriq Vision N locates any visible faults objectively and consistently. Defects in every roll are located and recorded at normal line running speeds. This equipment allows seamless integration of an inspection system into any production, detecting holes, irregularities, contamination and any other defect. The installation is easy and flexible.
To guarantee optimal defect detection, in combination with spectroscopes various light sources are integrated in the installation – all customized and suited to mill light conditions.
The inspection system provides real-time alerts, showing all defects and automatically creating roll inspection charts. All detected faults are collected in an album review. Here, the operator can quickly mark faults and select which can be deleted. Users can set their own quality standards for different types of nonwovens, increasing the efficiency of the grading process.
