Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of a tension unbalance due to unevenness in each of impression cylinders by a method wherein the tension of a paper sheet between printing units and between processing units is automatically gradually increased from an upper stream spot toward a downstream spot. SOLUTION: Tension detectors 7a-7e to detect the tension of a paper sheet W in respective positions are arranged in spots situated upper stream from the impression cylinders 4a-4c for printing of a printing part 2 and in spots situated upper stream from the tension roller of a processing part 3. Feedback of detecting values of tension detectors 7a-7f is effected to respective controllers 12a-12f to regulate the rotation speeds of the respective tensile rollers 12a-12f for impression cylinders 4a-4c for printing and a processing part 3. The rotation speeds of the respective tensile rollers 6a-6c for the printing impression cylinders 4a-4c and the processing part 3 are regulated to a rotation speed at which detecting values detected by the tension detectors 7a-7f are gradually increased from an upper stream spot toward a downstream spot.

[0005] (3) In the processing and folding section, the paper is fed by friction due to the partial pressure of the tension roller and the rubber roller, and air is mixed between the paper and the roller during rotation, and slip is likely to occur. Particularly in the high-speed range, the tension in the high-speed range becomes unstable, resulting in poor register registration for printing and poor register between the processing units such as the punching unit and the horizontal sewing unit. It was easy.
