  • Device for guiding sheets
    Patent number: 7328899
    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.
    Type: Grant

  • Sheet guide device in a rotary printing machine
    Patent number: 6729233
    Abstract: A sheet guide apparatus for use in a rotary printing press which is adapted for the smear and mark free transfer of sheets between two sheet holding and transfer systems, such as a pair of sheet-carrying cylinders or a sheet-carrying cylinder and circulating sheet conveyor. The sheet guide apparatus includes a sheet guide having a guide surface disposed beneath the transfer area, and a pneumatic system for blowing a positive pressure air stream in the direction of a transfer area or tangent point between the sheet holding and transfer systems. A further pneumatic system optionally may be provided for drawing or blowing air through apertures in the guide surface.
