Abstract

Die Erfindung betrifft ein Verfahren zur Erwärmung von Bedruckstoff und / oder Toner, insbesondere in einer elektrofotographisch arbeitenden Druckmaschine, mit wenigstens einer mit wenigstens einem Hohlkammerresonator ausgebildeten, stehenden Mikrowelle, wobei der Bedruckstoff durch einen Spalt des Resonators geführt wird.The invention relates to a method for heating printed material and / or toner, in particular in an electrophotographically operating printing press, with at least one standing with at least one Hohlkammerresonator standing microwave, the printing material is passed through a gap of the resonator.

Des weiteren betrifft die Erfindung eine Vorrichtung zur Erwärmung von Bedruckstoff und / oder Toner, insbesondere in einer elektrofotographisch arbeitenden Druckmaschine, die wenigstens einen Resonator mit wenigstens einer Hohlkammer für von einer Mikrowellenquelle ausgesandte Mikrowellen umfaßt, der wenigstens eine stehende Mikrowelle erzeugt und einen Spalt aufweist, durch den der Bedruckstoff hindurchführbar ist.Furthermore, the invention relates to a device for heating printed material and / or toner, in particular in an electrophotographic printing machine comprising at least one resonator with at least one hollow chamber for emitted from a microwave source microwaves, which generates at least one standing microwave and having a gap through which the printing material can be passed.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren bzw. eine Vorrichtung der genannten Gattung weiter zu verbessern.The invention has for its object to further improve a method and a device of the type mentioned.

Diese Aufgabe wird erfindungsgemäß in Verfahrenshinsicht dadurch gelöst, daß die Leistungsverteilung der vom Resonator applizierten Mikrowelle gezielt für den jeweiligen Bedarf ausgeformt oder konfiguriert wird.This object is achieved according to the invention in process view, characterized in that the power distribution of the microwave applied by the resonator is formed or configured specifically for the particular need.

Dadurch wird eine größere Unabhängigkeit von der Willkür bei einer Auswahl eines Resonators erreicht.
