Embodiment Construction
[0023]FIG. 1 shows a cross-sectional view of a blanket cylinder 1 with a bore 2 that passes through it. A supply line 3 is supported in the bore 2 on spacers 6. The spacers 6 have flow regions 7, which in the present case are formed as circular drill holes along the circumference of the spacer 6. The spacers 6 form a return duct 4 having an annular cross-section between the inside wall of the bore 2 and the supply line 3. The supply line 3 and return duct 4 are rotatably joined with the connector 5, which is rigidly mounted on a base of the blanket cylinder.
[0024] The connector 5 is preferably a rotationing union of the type sold by the Deublin Company of Waukegan, Ill. For the embodiment of FIG. 1, a Deublin 57 Series duo-flow union is especially suitable. Such a union can be fixed to a support framework of the rotating cylinder, and has sealed joints connecting the inlet line 12 and discharge line 13 to the supply line 3 and return duct 4 respectively.
