Abstract
Electronic device for controlling weft yarn insertion in continuous weft feed looms, without shuttles, adapted to stop the loom and emit a corresponding signal, not only each time there is a breakage or absence of a weft yarn, but also whenever the undesired insertion of double wefts occurs. This device comprises a plurality of transducers, each activated by a weft yarn, a logic network and means for stopping the loom, said logic network comprising means for storing a predetermined law of insertion of the individual weft yarns corresponding to a certain weaving operation on the loom, and for comparing with said law the actual weft insertions detected by the transducers.
