ABSTRACT:
The electronic weft stop motion is designed for monitoring the weft thread in a last phase immediately following the weft insertion into the weaving shed when a thread tensioning device located on the picking side of the machine laterally deflects the weft or filling thread and thus holds it tensioned. A tactile thread sensor is arranged in the region of the lateral deflection of the weft thread in such a manner that the thread sensor goes free from the weft thread in the undeflected condition thereof, however is frictionally contacted by the weft thread when the latter is being laterally deflected.
