Kind Code:
B2
Abstract:
To provide a gravure rotary printing machine comprising a furnisher roll contacting a plate cylinder, which can suppress ink from scattering to an end face of the plate cylinder and an axis of the furnisher roll.SOLUTION: In a gravure rotary printing machine, a furnisher roll is constituted of a columnar part at a center part and a truncated cone-shape part at a side part. In the truncated cone-shape part at the side part, a small-diameter surface becomes an end part of the furnisher roll and a large diameter part contacts the columnar part at the center part of the furnisher roll. The diameter of the large diameter surface is equal to the diameter of the columnar part at the center part of the furnisher roll. In a direction of an axis of the furnisher roll, an end part of a plate cylinder is positioned at the truncated cone-shape part at the side part of the furnisher roll.SELECTED DRAWING: Figure 1
