Abstract
PURPOSE:To prevent the penetration of ink in a bearing part and to make durability excellent, by, providing a pipeline for supplying compressed gas to the internal space of a non-contact type seal part and steadily discharging the gas from the small gap of the seal part. CONSTITUTION:The compressed air supplied to a flexible tube 24 is reduced in pressure by a pressure controller 23 and distributed in a circumferential direction by a circumferential groove 25 through an air supply hole 21 to be discharged to the atmosphere from a non-contact type seal part 26 through an air hole 27. Since this compressed air flows through the small gap of a seal part after reduction in pressure, the flow rate thereof is slight. Since this discharged air stream is steadily generated, there is no possibility such that the ink transferred to a plate cylinder cone 9 from a plate cylinder 11 flows in against an air stream and the adhesion of the ink to a bearing 4 is prevented. Further, it is unnecessary to use a material to be eroded by a solvent such as synthetic rubber in a bearing part and the damage of durability by the ink can be eliminated.
