ABSTRACT:
A roller electrode includes an elongated hollow roller, a stationary shaft, and an electrically conductive fluid. The hollow roller and the stationary shaft are electrically conductive. The hollow roller has an inner surface which confines an interior chamber. The stationary shaft is provided coaxially in the interior chamber of the hollow roller and is journalled to the hollow roller. The stationary shaft has an end section which extends out of the interior chamber for connection to a power supply. The fluid is provided in the interior chamber around the stationary shaft to provide a stable electrical connection between the stationary shaft and the hollow roller.
