Abstract (en)
[origin: EP0924324A1] A traveling sensor (1) moves along a track (4) past the spinning positions. An optical transducer (2) provides a signal for the interruption or reflection of a light beam by the yarn (15) as it passes by in the rotating balloon (16). The duration of the signal is evaluated to indicate statistical outliers in diameter or other irregularities.
