When the member 58 screwed onto the screw shaft 57 and rotatably supported by the bracket 54 is rotated by the axial registration device 18b, the adjustment shaft 40 moves in the axial direction, and the shell 36 also moves in the axial direction. . Therefore, the plate cylinder main body 34 and the shell 36 can be registered in the axial direction.

ストを低減できる。The divided plate cylinder device of the rotary printing press of the present invention is constructed as described above, and the following effects are achieved. (1) Drive the plate cylinder body and shell synchronously by driving one side of the divided plate cylinder from the drive side. Further, additional backlash between the drive helical gears can be kept extremely small. Therefore, printing problems such as scratches are less likely to occur. (2) The adjustment shaft passes through the plate cylinder main body and extends to the outside of the frame on the driving side to connect the divided plate cylinder, the circumferential direction registration device and the axial direction registration device, and the plate cylinder main body and The circumferential and axial registers of the shell can be performed separately, the result of each registration does not affect the other registers, and these registers can be performed during operation and stop. It can be carried out. (3) Since both journals of the plate cylinder body are supported as before, there is no sticking in the gap between the shell and the plate cylinder body, and it is difficult to cause co-rotation. The strength of the divided plate cylinder can be increased by shortening the frame span by extending the frame to the outside. (4) Since the driving helical gear on the operating side is no longer required, the register adjustment mechanism can be simplified, the number of parts can be reduced, and manufacturing costs can be reduced.
