PURPOSE: To constitute a form roller so as to enable the connection and interception of the motion of an ink distributing process by restricting an axial process on both sides in a roller shaft by two stoppers and regulating at least one of the stoppers in an axial direction. CONSTITUTION: A form roller 3 has a roller shaft 6 and the lateral process of a jacket 7 is restricted on the left side by the stopper ring 11 fixed to the roller shaft 6. That is, the left running ring 12 of a radial-axial bearing 8 collides with the stopper surface 13 of the stopper ring 11. On the right side, an axial process (almost 7-8 mm) is restricted by a shift ring 14. That is, the right running ring 16 of a radial-axial bearing 9 collides with the stopper surface 17 of the shift ring 14. The shift ring 14 is supported on the roller shaft 6 as a part of a regulator 18 in a revolvable and axial shiftable manner. |
