Abstract (en)
[origin: EP2319968A1] An air supply system to launch (10, 11) or relay (6) nozzle means for a weft yarn in a pneumatic weaving loom is disclosed. The system comprises at least one outlet on/off valve (V 1 ) controlling said nozzle means and further only another inlet on/off valve means (V 2 ) on the air supply conduit pertaining to said nozzle means upstream of said outlet on/off valve (V 1 ); between said two outlet valve (V 1 ) and inlet valve means (V 2 ) there is arranged a storage tank (Tk), of a volume suited to contain sufficient air for at least one weft yarn launch, and a pressure sensor (P) apt to drive said inlet valve means (V 2 ) so as to open when the pressure in the tank (Tk) drops below a preset minimum threshold (Psl) and to close when the pressure in the tank (Tk) rises above a preset maximum threshold (Psu).
