Abstract (en)
[origin: WO2011015178A1] On a weaving machine, the arrival of the weft thread (1) during insertion into a shed is monitored by means of a sensor (4) at the end of the insertion path (5). The sensor (4) produces different signal profiles (6) upon the passage of different weft threads (1,2,3...n). A control unit (7) determines the respective reference signal from several signal profiles (6) of the sensor (4) for each weft thread (1,2,3...n) to be inserted depending on the weaving pattern, the reference signal being compared with the actual signal profile (6) in the weaving process. The operator no longer has to make any entries into the controller (7) regarding the type of weft threads (1) to be monitored during weft insertion.
