Abstract

Air feeding and control device for the pneumatic transporting of the weft (18-21) in air-jet weaving machines, comprising a control system (24), connected to air feeding means, which comprise a compressed air source (2) and a series of nozzles (14-17), driven by respective electrovalves (10-13) and which can be used for inserting the weft; the air feeding means also comprise at least one air feeding and accumulation system (31), suitable for allowing a pre-established quantity of air to be accumulated when the air is not flowing to the nozzles (14-17) and suitable for regulating the air flow-rate when it is flowing to the nozzles (14-17).
