- A cylinder which is more or less electrically conductive at least in a region
- Means for rotatably supporting the cylinder about its cylinder axis and
- At least one means for supplying an electrical voltage to the electrically conductive region,
- The and an electrically conductive, to cylinder coaxial shaft or axis
- Having at least one cylinder for coaxial sliding ring of electrically conductive and flexible material, which rests slidably on the shaft or axle,
- Wherein either the electrically conductive shaft is rotationally fixedly connected to the cylinder and is electrically connected to the electrically conductive region of the cylinder, the slide ring is stationarily arranged and is connectable to an electrical power supply,
- Rotatably or the sliding ring is connected to the cylinder and is electrically connected to the electrically conductive region and the axis is stationary and can be connected to an electrical power supply.
