Abstract
A method for conveying a sheet includes guiding an electrically charged sheet pneumatically along a desired path, continuously detecting a charge distribution on the sheet, and reducing a positional deviation of the sheet from the desired path by actuating at least one actuating element influencing the position in dependence on the charge distribution. An apparatus for conveying a sheet includes a control device for the position of the sheet and a sensor connected to the control device for detecting an electric field present on the sheet. The method and apparatus permit the sheet to be guided with small deviations from the desired path.
