Abstract
An antistatic device for reducing electrostatic charges on moving material webs may include an active positive electrode assembly having a plurality of active individual positive electrodes electrically connected to a positive high voltage source. The device may include an active negative electrode assembly having a plurality of active negative electrodes electrically connected to a negative high voltage source. A sensor system may be included for detecting a polarity of a neutralizing current between the material web and the antistatic device during operation of the antistatic device, and a controller for controlling the high voltage sources. The controller may be coupled to the sensor system and may be at least one of programmed and configured to one of active or leave activated the high voltage source required in each case and one of deactivate and leave deactivated the high voltage source not required in each case in response to the detected polarity of the neutralizing current.
