PURPOSE:To provide a printing roll having a simple structure and to easily incorporate the same in a real machine by providing box-shaped space to the central part of a printing roll and arranging a wt. in the space through a member having a spring element and an attenuation element. CONSTITUTION:A blanket 3 is wound around the surface of a printing roll 1 composed of a rubber cylinder through a clamp device 2 and box-shaped space 4 is provided to the central part of the printing roll. A wt. 6 is arranged to the space 4 through a member 5 having a spring element composed of rubber and an attenuation element and the inherent vibration frequency in the direction right-angled to the axial direction of the wt. 6 and the member 5 is allowed to almost coincide with the bending inherent vibration frequency of the printing roll. |
