PROBLEM TO BE SOLVED: To naturally press the tip of a doctor blade to a plate cylinder uniformly left and right in parallel, and to prevent all the loads of a doctor holder and the doctor blade from being applied only to two left and right rods.SOLUTION: A fluid pressure doctor device 1 includes two left and right fluid pressure cylinders 20 and 20, a doctor holder 30 connected to the rods 25 and 25 of the two left and right fluid pressure cylinders 20 and 20, a doctor blade 40 held in the doctor holder 30, and reception members 9 and 9 for receiving the load of the doctor holder 30. By delivering the rods 25 and 25 at fluid pressure from the cylinder parts 21 and 21 of the two left and right fluid pressure cylinders 20 and 20, the doctor holder 30 and the doctor blade 40 are linearly moved in a delivering direction to press the tip of the doctor blade 40 to a plate cylinder 5.SELECTED DRAWING: Figure 1 |
