| 摘要 | PURPOSE:To prevent the printing surface from being scratched even when a number is not printed, etc. by so arranging a first printing unit for use in general printing and a second printing unit for use in printing of a number etc. as to be freely connected or separated each other, whereby said first printing unit of an offset printing press is rendered usable solely. CONSTITUTION:When a first and a second printing units 1, 2 are connected, a paper (a) printed between a rubber cylinder 4 and a press cylinder 5 is seized by a gripper 13 installed in a chain 12 and transferred to a press cylinder 14 of the second printing unit 2. Thereafter, the paper (a) is done with lateral and longitudinal perforations and numbering and the like, and transferred by a chain 21 to a paper discharging pad 22 while it is seized by a gripper 20 of a paper discharging cylinder 19 of a paper discharging section 18. When the second printing unit 2 is separated, the paper (a) seized by the gripper 13 is transferred by the chain 12 to a paper discharging pad 23.
