Abstract
The presence of yarns of a tentered yarn layer on a textile machine is checked by traversing a feeler transversely across a row of the threads to deflect the yarns. A pressure sensor of the feeler deflects each deflected yarn and generates a signal in response thereto. An optical sensor of the feeler detects each yarn and generates a second signal in response thereto which is compared to the first signal.
