Claims

[Scope of utility model registration request]

In the plate cylinder device of a rotary printing press, in which printing plates are mounted separately on the left and right sides of the plate cylinder, and the phase alignment can be finely adjusted separately in the vertical and axial directions during operation, both sides of the machine frame are used. The shaft is rotatably supported while its axial movement is restricted, and has a pair of through holes drilled in the diametrical direction at each end, and a pair of through holes drilled in the diametrical direction from both ends, respectively, so as to intersect with the through holes in the axial direction. a core body member having a pair of concentric holes drilled in the core body member, and having a length approximately half of the core body member;
a pair of thin plate cylinders rotatably and axially movably fitted to the outer circumferential surface of the core body member, and provided with a plate clamping member;
A pair of concentric shafts are rotatably and axially movably fitted into each of the pivot holes so as to intersect with the through holes, and a pair of concentric shafts are inserted into each of the through holes so as to intersect with the through holes. A pair of connecting shafts are inserted with a predetermined gap between them, both ends are fixed to the inner wall of the printing cylinder, and the center part is fixed to the concentric shaft, and each of the connecting shafts is connected to the end of each of the concentric shafts. an axial moving means configured to individually move each concentric shaft in the axial direction with respect to the core body member; What is claimed is: 1. A plate cylinder device for a rotary printing press, comprising: rotating means configured to rotate the plate cylinder relative to a core cylinder member.
