A process for spreading, electrostatically charging, and forwarding a fibrous web concomitantly formed with a vapor blast. The web is charged by passing it through a highly ionized zone created by a corona discharge between an ion gun and a target plate. The electrical potential between the ion gun and target plate causes current to flow which is sufficient to deposit a charge on the web which is preferably 75 to 100 percent of the maximum sustainable charge, but low enough to avoid loss of web charge through secondary corona discharge between the target plate and the web. |
