- the gear train 102 in which the reversing printing unit configured according to the invention is located can be operated in the perfecting mode, is designated by reference number 102, while reference number 103 is in the pure printing operation of the reversing printing unit called setting course of the drive.
- the individual waves from the first sheet-guiding cylinder 2, turning drum, transfer drum, additional Transport element and second sheet-guiding cylinder are all in one Side wall 99 of the reversing printing unit with bearings shown only schematically here 91 rotatably added.
- an engaged state 97 as well as a reach disengaged state 98 On the shaft of the transfer drum 9 can for example one of the gear wheels 105 or 104 in the axial direction, designated by the Travel 96 are shifted so that the distance a to engage or out Engage, just corresponds to a gear width.
- the sleeve-shaped element 100 on the circumference of which the outer gear 105 of the shaft of the transfer drum 9 is fastened, returns to a dashed position 101 so that it is effectively disengaged of the gear 104 with the drive gears 90 and 92 of the first and second arc-guiding cylinder 1, 20 is ensured.
- This choice of drive wheels is used to switch from straight printing mode 59 to Fine and reverse printing mode 60 by coupling between direct and indirect Drive via turning drum 14 on the transfer drum 9 Rotation of the drive systems to one another such that the turning drum 14th depending on the format, exactly the end of the sheet 1, 65 lying on the printing cylinder detected.
- straight printing mode 59 the drive takes place in such a way that the gear wheels 93 and 94, that are required in the perfecting mode 60, in a rest position of Reversing drum 14 and additional transport element 17 are disengaged
