Abstract

Die Erfindung betrifft eine Vorrichtung zur Bestäubung von Bogen (22) mittels eines Puderpartikel enthaltenden Pudergasvorhanges (28). Dieser ist auf eine von den Bogen (22) zurückgelegte Förderstrecke ausgerichtet und beaufschlagt die Bogen (22) von einer Seite derselben, die in einem mittels der bestäubten Bogen (22) gebildeten Stapel (20) nach unten weist. Dies ermöglicht einen relativ kurzen, von den Puderpartikeln bis zu deren Auftreffen auf die Bogen (22) zurückzulegenden Weg und somit eine verbesserte Ausbeute an auf den Bogen aufgetragenem Puder.

Figure 00000001
The invention relates to a device for dusting sheets (22) by means of a powder gas curtain (28) containing powder particles. This is aligned with a conveying path covered by the sheets (22) and acts on the sheets (22) from one side thereof, which points downward in a stack (20) formed by the dusted sheets (22). This enables a relatively short path to be covered from the powder particles to their impact on the sheets (22) and thus an improved yield of powder applied to the sheets.
