Abstract
In order to be able to adjust the tension and position of a material web, for example, a paper web, that should be printed by a printer, an electrostatically-acting braking device is described that provides a charger, for example, a corotron, and a braking plate, between which the material web runs. The charger charges the material web, which is thereby drawn to the braking plate, lies on the braking plate, and is braked via friction. It is advantageous that the charge voltage of the charger and be controlled via sensors for the web tension and web position and can very quickly react to the signals of the sensors.
