    摘要: The present invention is a method and apparatus for controlling free charge on a moving web. The method and apparatus includes two DC ionizers one of each polarity positioned near one surface of the web. A conductive plate mounted on the opposite side of the web opposite the DC ionizers is controlled in response to the free charge measured on the web downstream of the ionizers. The present invention allows control of the free charge on the web to almost zero without imparting any frequency in the charge on the web.
