、非能率的である。(Prior art) When changing printing presses, cleaning, and ink changes due to changes in job content during printing operations on rotary presses, conventional methods have been used to prevent the web on the printing press from wrapping around the printing cylinder. In the process, the web was cut and removed from the printing unit. However, it is inefficient to remove the web from the printing unit every time a plate change or the like is performed, as it requires the effort of introducing the web between the units again later.
