PURPOSE: To adjust a circumferential register during an operation of a printing machine by constituting a shaft of a plate base to be disposed at an intersection of a connecting line passing axes of a rubber cylinder and a plate cylinder and a connecting line passing axes of an impression cylinder and an intermediate gearwheel. CONSTITUTION: A plate cylinder 4 is held at a plate base 5, in a frame or the like, and driven by an intermediate gearwheel 6. Teeth of the gearwheel 6 are first engaged with teeth of an impression cylinder 3, and then with the cylinder 4. The gearwheel 6 is also rotatably held at the base 5, which is gradually rotatably disposed around a turning shaft 7. The shaft 7 is disposed at an intersection of connecting straight lines 8, 9. The line 8 passes the shaft 10 of the late 4 and the shaft 11 of the cylinder 2, extended together with the line 9 passing the shaft 12 of the gearwheel 6 and the shaft 13 of the cylinder 3 to support the base 5 to a height adjustable support bearing. Thus, since a turning motion of the base 5 can be executable around the shaft 7, a circumferential register of the cylinder 4 can be adjusted to the cylinder 2. |
