Abstract

Appts. to identify hazardous debris and foreign matter is fibre material, esp. cotton and manmade fibres has an analogue/digital converter (63) at the evaulation unit (14) for the signals from the camera (12) which monitors the material. The pref. camera (12) is a plane camera with a strobe light. ADVANTAGE - The system gives an improved monitoring action and determines the degree of soiling by unwanted matter in the fibres.
