A weaving machine having a filling breakage detector for generating an error signal upon breakage of a filling thread. This error signal then stops the weaving machine. A pick finding process is then initiated in which the weaving program is set back and then blocked. After removal of any filling thread in the open shed, the weaving machine is operated until the preceding shed is opened enabling the removal of the filling thread. If this is the ruptured filling thread, it is replaced by a new filling thread, the weaving program is unblocked and the weaving machine is operated in its normal sequence. If the filling thread is not ruptured once or if another ruptured filling thread is detected in a preceding shed, the pick finding process is repeated. The cloth takeoff and the warp letoff are also set back correspondingly with the weaving program.
Process for controlling a weaving machine, which is stopped by an error of a filling breakage detector, wherein for pick finding, the weaving program of a control device of a shedding apparatus is set back and the pick finding occurs with the weaving machine running forward, and additionally at least the cloth takeup is correspondingly set back, chracterized in that, after being set back, the step-by-step action of the weaving program in each pick finding cycle is blocked at least for that shed, which follows the shed in which the ruptured filling thread is being searched for, in such a way that the shed to be examined reamains open, at least as a double shed, during at least two filling cycles, whereupon the continuation of the sequentially correct next normal weaving process is triggered or, prior thereto, the pick finding cycle is repeated, for respective preceding sheds accompanied by corresponding set backs of the weaving program, until the ruptured filling thread is found.
