Abstract

A printing unit arrangement in a web-fed rotary printing press includes at least one printing unit 2a having a first and second plate cylinder 4, 6 and associated first and second blanket cylinders 8, 10 which are mechanically coupled via meshing gear wheels and which are commonly driven by one drive motor 12. A second printing unit of the printing unit arrangement includes a first and second plate cylinder 24, 26 and associated first and second blanket cylinders 28, 30. The first plate cylinder 24 and the first and second blanket cylinders 28, 30 are mechanically coupled via meshing gear wheels and are commonly driven by a first drive motor 42. The second plate cylinder 26 is individually driven by a second drive motor 46, and is engageable and disengageable from the associated second blanket cylinder 30 while the printing press is in operation, in order to perform flying edition changes or changes of a spot color.
