Abstract:
A method and an apparatus for laterally aligning a sheet in a processing machine, in particular a printing machine, carries out lateral sheet alignment on a cylinder of the printing machine, e.g. a feed cylinder. In order to achieve large correction distances in relation to a possible lateral movement capability of a gripper bar, the latter is prealigned prior to correction in such a way that, in the event of deviation from predetermined desired values, it is prealigned laterally to defined positions. A sheet-fed rotary printing machine having the apparatus, is also provided.
