Abstract
The invention relates to a device for detecting flaws in a plastic woven fabric made of monoaxially drawn polymer ribbons, in particular polyolefin ribbons, preferably polypropylene ribbons, wherein in order to monitor irregularities, which are characteristic of flawed sections of the plastic woven fabric, an inspection camera is provided for taking images of the plastic woven fabric, and an analysis unit, which detects irregularities in the weaving pattern of the plastic woven fabric on the basis of the images taken by the inspection camera and which, when detecting irregularities in the weaving pattern indicating a flawed section of the plastic woven fabric, triggers an error signal, which actuates, for example, a flashing light or a horn, or which can be fed to a higher-level machine controller. There is further provided a labelling device for attaching labels to the plastic woven fabric, wherein the labelling device is actuated directly or indirectly by the error signal, in order to attach at least one label to a flawed section.
