    • PROBLEM TO BE SOLVED: To provide a web offset printing press and an adjusting method of a tilt angle of a printing cylinder which enable more reliable reduction of delamination. SOLUTION: The web offset printing press performs printing on a web 10 at a nipping part of paired printing cylinders 9a and 9b which are opposite to each other and disposed in shifting in the direction of advance of the web 10, in a sequence of the first printing cylinder 9b on the upstream side and the second printing cylinder 9a on the downstream side. The press comprises a tilt angle adjusting mechanism 20 which adjusts a tilt angle α of a plane connecting both axes of the paired printing cylinders 9a and 9b, to a plane intersecting at right angles to the direction of conveyance of the web 10, and with a control means 30 which controls the tilt angle adjusting mechanism on the basis of parameters correlated with the probability of occurrence of the delamination caused by printing of the second printing cylinder 9a on the downstream side out of the paired printing cylinders 9a and 9b.

    • 要解决的问题:提供一种卷筒纸胶版印刷机和能够更可靠地降低分层的印刷滚筒的倾斜角度的调整方法。 卷筒纸胶版印刷机在成对的印刷滚筒9a和9b的夹持部分的纸幅10上进行打印,该印刷滚筒9a和9b彼此相对并沿着纸幅10的前进方向移动,按顺序 位于上游侧的第一印刷滚筒9b和下游侧的第二印刷滚筒9a。 压力机包括倾斜角度调节机构20,其将连接成对的印刷滚筒9a和9b的两个轴线的平面的倾斜角α调整到与卷筒纸10的传送方向成直角相交的平面, 控制装置30,其基于与在成对的印刷滚筒9a和9b中的下游侧的第二印刷滚筒9a的印刷所引起的分层的发生概率相关的参数来控制倾斜角度调节机构。 版权所有(C)2008,JPO&INPIT
