Winding device for winding a substantially insulating web material

A winding device for a substantially electrically insulating web material having a winding roller on which the web material can be wound, characterized in that an apparatus exists for transferring an electric charge to the web material on the winding roller, and when deflecting to the winding roller, and the apparatus for transferring an electric charge is connected to at least one electrical high-voltage source with a positive or negative polarity such that undesirable charge on the web material on the winding roller is reduced or avoided, wherein the winding device has an impression roller which deflects the web material to the winding roller and lies against the web material on the circumference of the winding roller in order to roll against it in the direction opposite that of the winding roller, wherein the impression roller has an electrically conductive layer or electrically semi-conductive layer on the circumference, an apparatus exists for transferring an electric charge to the electrically conductive layer or electrically semi-conductive layer of the impression roller, and the apparatus for transferring an electric charge to the conductive layer or electrically semi-conductive layer is connected to the electrical high-voltage source, and wherein the winding device has an idler roller that is arranged at a distance from the winding roller which has a rotary axis that is arranged parallel to the rotary axis of the idler roller, so that the web material is guided by the idler roller to the circumference of the impression roller, deflected by the impression roller, and guided on the circumference of the winding roller.
