ABSTRACT:
In order to improve mechanical positive synchronization in a sheet-fed printing machine between gripper carriages guided in wave-like fashion through printing units on endless chains and the associated impression cylinder, the impression cylinders (1) have twice the diameter of the plate and blanket cylinders (2, 3). Sprocket wheels (34), also of twice the diameter of the blanket cylinders, are fixed on the ends of the double-size impression cylinders (1) and on them there are disposed two diametrically opposite gripper carriage locating and fixing devices (24-32) which are adjustable both radially and tangentially and which can also be used to bring the different printing plates into register with one another on the printed sheet (38).
