Patent ID: 7478807

Claim:
A method for conveying a sheet, which comprises the following steps: providing an apparatus for conveying a sheet, the apparatus including: a desired path for a pneumatically guided, electrically charged sheet; a sensor for continuously detecting a charge distribution of an electric field present on the sheet; at least one actuating element for influencing a position of the sheet; a control device connected to the sensor and to the at least one actuating element for actuating the at least one actuating element in dependence on the charge distribution to reduce a deviation in the position of the sheet from the desired path; a revolving drum having a circumferential contour; grippers disposed on the revolving drum for holding the sheet; a sheet guide plate disposed along the circumferential contour of the drum and defining the desired path, the sensor being structurally combined with the sheet guide plate; a blown air device forming the at least one actuating element and being disposed along the circumferential contour of the drum; and another sensor disposed along the circumferential contour for sensing a floating height of the sheet above the guide plate; pneumatically guiding the electrically charged sheet along the desired path; continuously detecting the charge distribution on the sheet; and reducing the deviation in a position of the sheet from the desired path by actuating the at least one actuating element influencing the position in dependence on the charge distribution.
