ABSTRACT:
The invention relates to a process and a device for detecting extraneous substances and extraneous fibers in a fibrous composite. In order to detect extraneous substances and extraneous fibers, on the one hand when they may make their presence felt in a disruptive manner because of their concentrated nature, and on the other hand, when they are not already processed in a finished product, the fibrous composite (2) is to be shaped to form a band (4) and the extraneous substances and extraneous fibers are to be detected in the band.
