ABSTRACT:
A system and method of transporting a sheet along a sheet path with electrostatic forces by applying corona charges to the sheet in pulses from high voltage corona generating electrodes in plural arrays extending along at least one side of the sheet path and subjecting the charged sheet to an electrical field pattern, defined by unevenly opposing electrodes spaced on the opposite side of the sheet path to provide an electrostatic force component acting on the charged sheet to move the sheet along the sheet path. The unevenly opposing electrodes may include grounded electrodes adjacent the downstream end of each array and commonly biased electrodes adjacent the upstream end of each array. Three different embodiments are illustrated.
