  • the assignment of the self-drive 26 and the arrangement of the printing form cylinder drive wheel 21 on the printing form cylinder 10 are shown in FIG. 3.
  • the printing form cylinder drive wheel 21 is assigned to the printing form cylinder 10 via a phase position clutch 27.
  • the printing form cylinder drive wheel 21 is arranged in the gear train of the printing press and meshes with the offset cylinder drive wheel 17 and the application roller drive wheel 22.
  • the printing form cylinder 10 is assigned the self-drive 26 via a metal bellows coupling 28.
  • the self-propulsion is designed as an electric motor.
  • the method according to the invention is characterized in a printing press with a cylinder group 11 or 18 in that the drive connection (drive connection 4 - in the operating phase position) between the printing plate cylinder 10 and the printing plate cylinder drive wheel 21 is released by means of the phase position coupling 27 and thus the printing plate cylinder is quasi separated from the drive wheel train and the printing form cylinder 10 is driven by the self-drive 26 in the imaging phase.
  • the speed of the printing form cylinder 10 during imaging i.e. the imaging speed is significantly higher than the maximum printing speed and is preferably 2-5 times the same.
  • the printing form cylinder 10 is reintegrated into the drive wheel train in the operating phase position by means of the phase position coupling 27.
  • Operating phase position means that the pressure starts 29 face the cylinders that are in operative connection and that printing operation is possible.
  • a current for braking the printing press and for bracing the drive wheel train is applied to the self-drive 26 in printing operation.
  • the existing self-propulsion is used to ensure tensioning of the drive wheel train in printing mode.
  • the current supplied to the self-propulsion is preferably in the range of 10% of the current of the main drive motor 12.
  • the drive connection between the printing forme cylinder drive wheel 21 and the drive wheel train is separated so that the printing forme cylinder can be separated from the drive wheel train and the printing form cylinder can be driven by the self-propelled in the imaging phase.
  • the printing form cylinder 10 is reintegrated into the drive wheel train by rotating the eccentric bearing 30 in the operating phase position.
  • Operating phase position means that the pressure beginnings of the cylinders in operative connection face each other and printing is possible.
  • the printing form cylinders 10 are now driven by the self-drive 26 at an imaging speed.
  • the printing form cylinders 10 are brought into an in-phase position relative to the imaging devices 16 from the respective operating phase positions.
  • the in-phase position of the printing form cylinders 10 relative to the imaging devices 16 is preferably identical to the start of printing 29, ie that at the beginning of the Imaging process, both printing form cylinders 10 with their printing starts face the respective imaging device 16.
  • the printing form cylinders 10 are driven synchronously at the imaging speed.
  • the printing form cylinders 10 are brought back into their respective operating phase positions. This is done as described below:
  • the operating phase of the respective printing form cylinder is overrun by the self-drive 26, i.e. the self-propulsion is stopped after passing the operating phase, then the printing form cylinder is integrated into the drive wheel train and mechanical means (phase coupling) take over the exact starting of the operating phase when the drive wheel train is started.
  • the operating phase is started with the following process steps:
  • the self-propulsion of the printing form cylinder is stopped before reaching the operating phase position, then the printing form cylinder is integrated into the drive wheel train and mechanical means (phase coupling) take over the exact starting of the operating phase position when the self-propulsion is started.
  • At least one self-drive in the manner described is supplied with a current for braking the printing press and bracing the drive wheel train.
  • the self-drive arranged on the printing form cylinder is also used in part or in total for driving the printing press in printing operation.
  • This embodiment is shown in FIGS. 6 and 7 and is described below using the drive scheme of the printing press in the four-color version with two cylinder groups.
  • each of the two printing form cylinders with the printing form cylinder drive wheels 21 is assigned its own drive 26.
  • the drive wheel train of the printing press contains, in addition to the forme cylinder drive wheels 21, two offset cylinder drive wheels 17, one impression cylinder drive wheel 15, two applicator roller drive wheels 22, one pre-gripper system. star drive wheel 31, a leading edge separator drive wheel 32, a delivery intermediate wheel 33 and a delivery chain circuit drive wheel 34.
  • the printing form cylinder drive wheels 21 are not actively incorporated into the drive wheel train and the self-propulsion drives 26 only drive the printing form cylinders; the printing press is not driven and is at a standstill.
  • inactive incorporation of the printing forme cylinder drive wheels 21 is understood to mean either a separation of the respective printing forme cylinder drive wheel 21 from the printing form cylinder via a clutch or a release of the printing form cylinder drive wheel 21 firmly connected to the printing form cylinder from the drive wheel train by pivoting the eccentrically mounted printing form cylinder including printing form cylinder drive wheels 21 .
  • the printing form cylinder drive wheels 2 are actively incorporated into the drive wheel train and at least one self-drive 26 drives the printing machine in whole or in part.
  • the motor which is normally provided for driving the printing press is omitted and all of the components of the printing press are driven by at least one self-drive 26.
  • the self-drives must be synchronized.
  • the uniformly rotating assemblies are driven by at least one internal drive 26 via their drive wheels - printing cylinder drive wheel 15, offset cylinder drive wheels 17, printing cylinder drive wheels 21 and applicator roller drive wheels 22.
  • the non-uniformly rotating assemblies - pre-gripper 6, front edge separator 4, delivery chain circuit 7 - are driven by the motor 12 by their drive wheels - pre-gripper system drive wheel 31, first intermediate wheel 35, second intermediate wheel 36, third intermediate wheel 37, delivery intermediate wheel 33, delivery chain drive wheel 34.
  • This variant is advantageous because the drives that cause vibrations have their own drive wheel train.
  • the motor 12 is synchronized with the self-propulsion or the self-propulsion. Another assignment of the modules to be driven to the motor and to the self-propulsion or the self-propulsion is also possible.
  • the method according to the invention is characterized in a printing press with a cylinder group in that the drive connection (drive connection in the operating phase position) is separated between the printing form cylinder and the drive wheel train, so that the printing form cylinder is separated from the drive wheel train and the printing form cylinder is driven by the self-drive 26 in the development phase.
