The dusting device (44) is used to coat each of the printed sheets with a uniform powder layer for preventing them from sticking together when stacked, with recovery of the excess powder via a suction device. A powder gas generator provides a gas stream containing the suspended powder particles, fed to a dusting rail with at least one discharge opening (64), the suction device having 2 flat suction channels (52,54) positioned on either side of the dusting rail and extending across the full width of the latter. |
