<p><P>PROBLEM TO BE SOLVED: To provide a printing machine, the diameters of printing cylinders of which can be changed and, at the same time, the entry of oil and oil mist into a printing unit can be fully prevented from developing. <P>SOLUTION: In a rotary printing machine 1, the diameter of a blanket cylinder 17 of which can be made possible to change, a first frame side slinger plate 67 provided projecting towards a shaft 33 so as to extend nearly normal to the axis line of the printing cylinder at the peripheral edge of a hole 49, through which the shaft 33 of the printing cylinder provided on a driving side frame 23 and a first blanket cylinder side slinger plate 83 provided nearly parallel to the first frame side slinger plate 67 under the condition that a gap is held in the direction of the axis line of the printing cylinder between the first frame side slinger plate 67 and the first blanket cylinder side slinger plate 83 about the periphery of the shaft 33. On the tip positions of the first frame side slinger plate 67 and of the first blanket cylinder side slinger plate 83, in all the positions, to which the blanket cylinder 17 move in accompany with the change of its diameter, the first frame side slinger plate 67 and the first blanket cylinder side slinger plate 83 are set to overlap with each other. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
