Monitoring the product quality of airbag fabrics is an important part in the manufacture of an airbag. Thereby the aim is to detect faults in the fabric early and to identify possible sources of error. In this paper, a special inspection method is presented that allows detecting mechanical damages that cannot be detected by previous used inspection systems. For that purpose the fabric is observed under a flat camera angle. Destroyed fiber sections, which express themselves in line-like structures in the images, are recognized by a custom image analysis method. Thus, the human inspector can be supported by the detection of difficult recognizable mechanical damages and a further step towards a hundred percent control of airbag fabrics is ensured.
