    摘要: A nine-cylinder satellite printing unit includes printing stations having a first, second, third and fourth transfer cylinder which a web passes through. The transfer cylinders are capable of being stopped when the printing assembly is switched off. A distance between each of the first and second transfer cylinders, the second and third transfer cylinders, and the third and fourth transfer cylinder is shorter than the distance between the first and fourth transfer cylinder. A guide roller keeps a supplied portion of the web away from the first transfer cylinder and another guide roller keeps a discharged portion web away from the fourth transfer cylinder when the first and fourth printing cylinders are respectively in print thrown-off positions.
