SOLUTION: The distributing roller drive device is equipped with a center gear 1 to be driven by a printing unit cylinder and distributing rollers 6 whose drive gear 5 is engaged with the center gear 1. These distributing rollers 6 are moved in the axial direction. The center gear 1 is of a double gear structure, the first gear 2 of which is engaged with a printing unit cylinder with a second gear 4 being engaged with the drive gear 5 of the distributing rollers 6 and supported by a journal 15. Two gears 2, 4 have internal gears 23, 24, with which the two gear rims 21, 22 of a planetary gear 20 are engaged. The planetary gear 20 is supported by the journal 15 for supporting the movable second gear 4. |
