Abstract:
Gegenstand der vorliegenden Erfindung ist eine mobile Sprühpistole, mit der eine Strahlungshärtung eingeleitet werden kann, ohne dass der Operateur vor Strahlung geschützt werden muss. Dies wird erreich durch eine mobile Sprühpistole, umfassend einen Zufuhrkanal 2 für eine strahlungshärtbare Beschichtungsmasse, eine in Längsrichtung bewegliche Nadel 1, mit der der Zufuhrkanal 2, der einen Ringspalt um die Nadel 1 bildet, gegen die Mündung 13 des Zufuhrkanals 2 abgedichtet werden kann, wobei die Nadel 1 so ausgestaltet ist, dass sie für elektromagnetische Strahlung durchlässig ist, mit der eine Härtung der strahlungshärtbaren Beschichtungsmasse eingeleitet werden kann und/oder die Zuleitung 12 transparent für elektromagnetische Strahlung ausgestaltet ist und eine Beleuchtungseinheit 10 an derZuleitung 12 angebracht ist.
