A driving device for printing machines, having a rod for oscillatingly moving a distributor roller in axial direction, includes a joint via which the rod is connected to the distributor roller, the joint permitting relative movement between the rod and the distributor roller so as to compensate for a displacement of the distributor roller perpendicularly to the axial direction of the distributor roller; and a printing machine having the driving device.

Driving device for printing machines

A sheet-fed printing machine having a feed system for feeding sheets from a sheet feeder to the sheet-fed printing machine, and an imaging device for setting an image on a printing plate disposed on the plate cylinder are provided. The feed system includes at least one oscillatingly moving pregripper and a drive device for the feed system, the pregripper being uncoupled from the drive device.

Sheet-fed printing machine and method of operation

A cylinder for receiving a printing form, the cylinder being formed with a gap having gap edges, which projects into the interior of the cylinder, the gap extending in a direction of generatrices of the cylinder and serving for guiding ends of a printing form therethrough, includes device for tautening the printing form on a jacket surface of the cylinder, at least one of the gap edges having a curvature for attaining tensioning forces which are constant over at least approximately the entire width of the printing form.

Cylinder for receiving a printing form including cylinder gap with curved gap edges

A method for laterally aligning a sheet in a sheet-processing machine, the sheet being retained by sheet grippers which are displaced axially on a common carriage with respect to an alignment cylinder, includes fixing the carriage when it reaches a predetermined desired position; and device for performing the method.
