In addition, since the number of paper feed units 1 and print units 2 used is limited by the number of pages to be produced, one or a plurality of paper feed units 1 and print units 2 are not used. In order to improve the operation rate of the rotary press, it is desired that these unused paper feeding units 1 and printing units 2 are further used for separate printing processes. However, there are two cutting / folding mechanisms 90 and 90 ′. When one of the cutting / folding mechanisms 90 is used, the other cutting / folding mechanism 90 ′ has no other drive source and cannot be driven individually. Therefore, it was impossible to produce a separate newspaper using the paper feed unit 1 and the print unit 2 that were not used. As a conventional technique, there is no means for effectively using the unused sheet feeding unit 1 and printing unit 2.
