Abstract

A sheet-fed, rotary, printing press for printing on both sides of sheets without a sheet reversing device, includes printing units having a modular construction. Each module includes at least a plate cylinder, a blanket cylinder, an impression cylinder, a transfer cylinder and at least one drive wheel. Modules for printing on the first side of the sheets and modules for printing on the second side of the sheets have an identical construction and are disposed in such a way that one is rotated through 180° relative to the other about an axis extending in a sheet processing direction.
