ABSTRACT:
A powder spray coating facility is automatically switched between a first operating mode in which only recovery powder is moved into an intermediate receptacle, and a second operating mode in which only fresh powder from a fresh powder unit is fed to the intermediate receptacle. Switching may be carried out from the second operating mode to a reserve powder operating mode when, following switching from the first operating mode to the second operating mode, an intermediate receptacle sensor continues to transmit a “powder needed” signal.
