In a jet loom embodying the present invention, in general, measured lengths of the weft yarn are inserted by fluid actuation into the shed delimited between the upper and lower warp yarns. When stop signals for the loom are sensed, the weft yarn about to be inserted into the shed is deflected under suction from its normal course and thus inhibited from entering the warp shed until the time of complete stop of the operation of the loom, which is braked. After the termination of braking, the moving components of the loom are operated in reverse and brought in this manner to a predetermined angular position of one weaving cycle. With the loom resting in this position, the lastly inserted weft yarn is disposed of.Suction of the weft yarn is performed by a suction pipe having a suction opening disposed near the usual weft route. This suction pipe is mounted for example intermediate the jet nozzle and the selvage towards the jet nozzle, intermediate the weft yarn supply unit and the jet nozzle or in the neighborhood of the temple.According to preferred embodiments, a structure is provided for guiding the weft yarn toward the suction opening of said suction pipe.
