The assembly to give a centralised pneumatic distribution of powder materials to different stations (1,2) has a main channel (8) with an inserted consumption monitor (7). The monitor (7) is connected to the multi-path distributor (9, 10) at the upstream powder vats (3,4) and to the multi-path distributor (11, 12) at the downstream stations (1, 2). The supply and movement of the ingredients pref. gives a constant consumption in a diluted phase in the main channel (8). The main channel (8) has an air lock (13) at the entry for the carrier to be evacuated. The supply vats (3,4) pref. have a return channel (14) to give a closed circuit when the stations (1, 2) require no supplies. The powder supply rate is pref. controlled by the monitor (7) acting on a weighing plate to give measured doses in cycles, with or without injection, for the stations (1,2). The stations (1,2) can have automatically controlled inlets to take the powder materials. The multi-path flaps (11, 12) at the stations (1,2) can be operated by a time control. The automatic station inlets are interrogated in cycles by the common feed control, to determine if a dose of powder should pass to the stations (1, 2) or not. USE/ADVANTAGE - The assembly is for the distribution of powder ingredients to textile dyeing stations, e.g. salts like sodium chloride or sodium sulphate. The system gives a progressive and automatic dosage of powder materials, of different types, to a number of dyeing stations in a central assembly.
