Title:
SHOCK MARK PREVENTING APPARATUS OF PRINTING PRESS
Document Type and Number:
Japanese Patent JP3294162
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus constituted not only to prevent vibration by eliminating the fluctuations of the force acting on a printing cylinder to prevent printing irregularity but also to enhance printing quality.
SOLUTION: A shock mark preventing apparatus 1 of a printing press is equipped with a pressure means 2 constituted so that clamp grooves 12A are formed to the surfaces of a plurality of printing cylinders 10 reversively rotated in mutual contact state under a predetermined contact pressure and the fluctuations of the contact pressure generated when the clamp grooves 12A are brought to a mutual contact state accompanying the rotation of the printing cylinders 10 are suppressed and the printing cylinders 10 are pressed to the opposite side of the clamp grooves 12A in matching relation to the rotary cycles of the respective printing cylinders 10. Therefore, the forces acting on the printing cylinders 10 are not cyclically fluctuated and, as a result, vibration is prevented and the printing irregularity caused by vibration is reduced and printing quality is enhanced.
