PROBLEM TO BE SOLVED: To adjust easily only a nip-width of a liquid-forming roller for a liquid-feeding roller. SOLUTION: The nip-width adjustment device consists of angle-displacement members 6, 31 installed at the both ends of the liquid-feeding roller 3 with a possibility of the angle displacement, support members 10, 36 for the liquid forming roller supporting the roller shaft at the both sides part from pins 7, 32 with a possibility of the angle displacement by making the pins 7, 32 installed in parallel to the axial center of the liquid feeding roller form the side of each angle-displacement member to be an axis and nip-width adjustment mechanism 14, 15, 37, 38 capable of adjusting the nip-width of the liquid forming roller contacting the liquid feeding roller, and a plane passing through the axial center lines of the pin and the plate cylinder is positioned adjacent to the axial center line of the liquid forming roller contacting the plate and liquid feeding roller, and the common contact-plane of the section where the liquid feeding roller and the liquid forming roller contact is positioned close to the axiel center line of the pin. |
