Abstract
An apparatus for fixing a sheet on the surface of an electrically conductive cylinder of a printing machine for processing sheets, in particular, a sheet-fed offset printing machine. The apparatus includes an electrode that extends over the width of the cylinder for creating an electric field for adhering the sheet to the surface of the cylinder and an air directing device for directing pressurized air streams against the sheet and preliminary positioning the sheet onto the cylinder prior to being acted upon by the electric field. Various alternative embodiments of the sheet fixing apparatus are disclosed.
