<p>A method and an apparatus (40) for detecting foreign materials in a moving textile material (5), in particular in moving threads, yarns or slivers is described comprising providing a probe (41) for picking up triboelectric signals from the moving textile material (5) and comparing the output of the probe (41) with a reference value to provide a signal representative of detection of a foreign material in the textile material (5). The apparatus (40) may be used in a card, a drawing bench, a ring spinning machine, an air-jet spinning machine, an open-end spinning machine, a chemical spinning machine, a bobbin winding machine a doubling machine, a combing machine, a bobbin frame, a texturing machine or a loom. <IMAGE></p> |
