Abstract

A printing group of a printing press includes at least one form cylinder that has at least one axially extending opening on the external surface of the cylinder. That at least one axially extending opening forms a channel in the cylinder and in which channel several printing form end retaining assemblies are provided. These retaining assemblies are provided in the channel on both sides of a center plane which bisects the form cylinder perpendicularly to its axis of rotation. A first one of these retaining assemblies that adjoins the center plane cooperates with a second retaining assembly, located on the other side of the center plane, to both engage the same printing form, in a first mode of operation. In a second mode of operation, the first retaining assembly cooperates with a third retaining assembly, that is located further away from the center plane, and on the same side thereof as the first retaining assembly, to engage a second printing form.
