Zusammenfassung
(EN)
The invention relates to a device (1) for identifying foreign parts during spinning preparation comprising an inspection channel (10) through which a fibre material stream (11) can be conducted wherein foreign parts (12) are present and can be identified in said fibre material stream (11) and for this purpose a first lighting unit (13) and at least one second lighting unit (14) are provided for irradiating light (16 17) into the inspection channel (10) and at least one camera (15) is provided with which light (16 17) that is generated by the lighting units (13) and reflected by the foreign part (12) can be detected. According to the invention the first lighting unit (13) is designed to emit light (16) with a first polarisation direction (A) and the second lighting unit (14) is designed to emit light (17) with a second polarisation direction (B) wherein the second polarisation direction (B) differs from the first polarisation direction (A).
