Abstract
The present invention relates to a corona station for the preliminary processing of a strip material. The corona station includes at least one electrode (18) connected to a high-voltage power supply through connection means, a housing containing at least partially the electrode (18) and the connection means, and at least one cylindrical counter-electrode (17), wherein the strip of material (16) does not rest on the whole surface of said counter-electrode (17).
Claims11
A corona station for pretreating a material web, having at least one electrode, which can be connected to a high-voltage supply via connecting means, a housing which at least partially accommodates the electrode and the connecting means, and having at least one counter-electrode of cylindrical construction, the counter-electrode has depressions on its circumferential surface, the depressions are arranged at least in subregions in the form of a regular grid, characterized in that an air nozzle is provided at least upstream of the counter-electrode, seen in the conveying direction of the material web and the material web does not bear with its whole surface against the counter-electrode.
