<p>A deflecting device includes a deflecting electrode (13), which is disposed at a spacing below a lip nozzle (11.1), from which the viscous coating material (10.2, 10.1) flowing freely in the form of a sheet is emerging, and which extends over the entire width of the coating material sheet. This deflecting electrode includes an electrode arrangement (31), the exposure region of which facing the sheet surface is subdivided into a number of electrode elements (33) which taper outwardly to a point. When placed under a voltage, the electrode arrangement (31) provides an ion stream directed towards the surface of the coating material sheet. The impact of this ion stream on the surface of the coating material sheet (10.2) imparts to the latter a change in direction ( alpha ) towards the deflecting electrode (13), so that a flat substrate (5.1) running horizontally towards the deflected coating material sheet (10.1) impinges on the sheet (10.1) at an acute angle ( beta ). The impact of the substrate (5.1) on the sheet (10.1) at an acute angle causes a smooth, undulation-free application of the coating material to the substrate surface.</p> |
