ABSTRACT:
An airjet weaving machine weft thread supply includes at least two thread preparation mechanisms and detectors for detecting thread breaks. When the detectors detect a thread break, a control unit deactivates the thread preparation mechanism in which the thread break has occurred and transfers the task of the deactivated thread preparation mechanism to another thread preparation mechanism. The control unit also activates an alarm signalling system and may also cause the main drive of the weaving machine to shut off in response to detection of a thread break.
