PURPOSE:To certainly and uniformly supply ink or water by a method wherein a cam connecting protrusion is provided on an inner shaft on which a reciprocating roller main body is loosely mounted, and an axial-direction transfer cam is divided into two parts along or perpendicularly to a cam groove, combined into a piece by fixing members and connected to the cam connecting protrusion. CONSTITUTION:An axial-direction transfer cam body 6 is divided into two parts by cutting off a part of the barrel between flanges 5, so that a cam groove 6a is formed by cut-off end faces 5a which face each other. A cam body connecting protrusion 4 on an inner shaft 3 is inserted in the cam groove 6a, and the flanges 5 are connected into a piece by a connecting ring 7 and set screws 8. When rollers are turned, a reciprocating roller main body 1, which is in contact with an ink transfer roller 12, is rotated and reciprocates a desired distance in the axial direction at a desired speed via the cam body connecting protrusion 4 and the cam groove 6 which is on the inner circumferential face of the reciprocating roller main body 1 and connected to the protrusion 4. Thereby, ink supplied between the ink transfer roller 12 and the reciprocating roller main body 1 is uniformly distributed and transferred onto a form roller 14 and then to a printing machine 15. |
