ABSTRACT:
A cylinder unit is provided for a web-fed printing press. The unit includes first and second cylinders which form printing gaps with a common first counterpressure cylinder. Third and fourth cylinders are provided which form printing gaps with a common second counterpressure cylinder. The four cylinders and the two counterpressure cylinders are cylinders of a single H-shaped cylinder bridge. The second and third cylinders are spaced from one another at such a distance that a web can run in between these two cylinders in their printing-on positions at the respective counterpressure cylinders and can run out after wrapping around the two counterpressure cylinders. The first and fourth cylinders are spaced so close to one another that they can be reversed from a printing-on position against their respective counterpressure cylinder into printing-on position in relation to one another.
