ABSTRACT:
A weaving machine is of the type in which the weft thread remains attached to the edge of the cloth between successive picks, the weft thread moving along with the cloth as the weaving process progresses, and in which detection of a thread break causes deactivation of a corresponding thread preparation mechanism and transfer of its task to another thread preparation mechanism. The weaving machine includes a monitoring device which, in the case of a thread break, sets a limit as to how much further the broken section of weft thread which is attached to the cloth can move. The monitoring device supplies an output signal so that further action can be taken to prevent further movement of the broken weft thread along with the cloth.
