PURPOSE: To enhance printing quality by connecting a ring to a journal to fix the same at the replacement of a sleeve. CONSTITUTION: When a sleeve-shaped rubber blanket is replaced, that is, when a bearing 10 is released, an eccentrically formed ring 12 becomes a state not rotated with respect to a blanket cylinder 1. Further, the rotation of the blanket cylinder 1 is prevented by the drive device connected to a journal 3. Further, the drive device is connected to the journal 3 and the blanket cylinder 1 is supported in a state floated in the air in the released bearing 10 by the device so as to keep equilibrium. The rubber blanket 31 replaceable in a released journal 2 is shown by a chain line. After the replacement of the rubber blanket 31 is completed, sliders 7, 8 are moved. |
