Abstract
Between the supply bobbin and a thread tensioner supplied therefrom, which comprises a thread guide (12) which can rotate around an axis of rotation (11), are disposed a fixed thread guiding component (3) and an optical sensor (20) for monitoring the weft thread (2), which is guided by the sensor (20) and an inlet channel (18), which passes through the thread guide (12) in the axial direction, towards the thread tensioner (5). The inlet channel (18) of the thread guide (12) is eccentrically offset with respect to its axis of rotation (11), so that the section of the weft thread (2) running towards it is laterally deflected and a rotational movement which can be detected by the sensor (20) is imparted to this section, and enables a safe monitoring of the weft thread (2) with minimal thread tension. A guide piece which has a guide channel eccentrically disposed with respect to the axis of rotation (11) and can be mounted on the thread guide (12) may also be provided as means to deflect the weft thread (2).
