Abstract

An apparatus for guiding and transferring a sheet in a printing machine from a first cylinder to a gripper of a second cylinder in which the apparatus has a guide device for a holding element, which is held outside the first and second cylinder. In this way, the design of the guide apparatus can be independent of the first and second cylinders. In addition, a longer time period is available for gripping, tensioning and transferring the sheet. The apparatus can be used both in a recto printing machine and in a turner device in recto and verso printing.
