Abstract

A sheet-guiding device has a sheet-guiding element for a sheet-fed printing machine having an impression cylinder and a further cylinder adjacent thereto, the sheet-guiding element being disposed for guiding a sheet transported by the impression cylinder when the further cylinder is set-off from the impression cylinder. The further cylinder includes a cylinder selected from the group thereof consisting of an applicator cylinder for applying ink or varnish, respectively, to a sheet lying on the impression cylinder, and a tool cylinder for applying a finishing step to a sheet lying on the impression cylinder. The sheet-guiding element is disposed separately from the further cylinder and covers an impression zone of the impression cylinder.
