Subsequently thereto, the setting of the relative pat- tern rapport of the printing stations relative to one another is obtained, which printing stations are associated with a particular printing run. For this, the gear 43 is first released by the device 47 and the friction coupling 45 engaged, so that with still as yet un-operated setting devices 51 and 57 the printing cylinder 28 is started up and accelerated, until it has a circumferential speed corresponding to the drive of the main drive shaft 39.

Once this is achieved, then additionally the coupling 48 is engaged, and the friction coupling 45 may remain in engagement during this period.

The printing cylinder 28 now idles corresponding to the drive of the main drive shaft 39, via the planetary gear stage 41. The speed of the carrier band thus corresponds to the intended production speed, but the relative pattern rapport has not yet been achieved.

The phase position of each mark of each carrier band of the printing stations associated for a particular operating run is now observed via an observation device and 35 a computer as well as a subsequentially arranged indicating instrument, for example a screen. If this phase position does not yet agree, i.e. if the relative pattern rapport has not yet been reached, then actuation of one or both setting devices 51 and 57 briefly supplies a drive to the second input 49 of the planetary gear stage 41, so that the corresponding carrier band is additionally accelerated or delayed, depending upon the direction of rotation effected by the setting device 51. In this manner, the mark of the carrier band of one printing station can be shifted relative to the mark of the carrier band of another printing station, until the relative pattern rap- port is achieved, taking into account the distance be- ween the two associated printing stations. When the marks overlap one another, i.e. are in rapport, then the time has come at which these two printing stations can be pressed against the paper web, i.e. at which printing is immediately possible in rapport without printing of scrap and without interrupting of the corrugated paper manufacture.

This switch-over from idling to printing is mostly effected by appropriate displacement of the counter- pressure cylinder 29, which is moved against the printing cylinder 28.

I claim:

1. An arrangement for manufacturing printed corrugated paper cuts with a corrugated paper machine, comprising: an integrated rotary printing machine having a plurality of printing stations in said corrugated paper machine; longitudinal cutter means and trans- verse cutter means; drive means; said printing stations being integrated for printing a paper web with laterally adjacent areas of different width and length which are selectively connectable with said drive means; said printing stations carrying for each area printing forms mounted on an endless exchangeable carrier band of different lengths, said longitudinal cutter means and transverse cutter means being provided for different area lengths; transmission means having a friction collpling and a mechanical engagement coupling for driving integrated printing stations from said drive means of the corrugated paper machine; said transmission means of each printing station having a planetary gear stage with one input connecta§1e via said two couplings with a drive shaft of the corrugated paper machine for set- ting carrier bands carrying printing forms of printing stations with reference to one another, said planetary gear stage having a second input connectable with at least one setting device, said planetary gear stage having one output leading to a printing cylinder of the printing station.源1自37518.论~文'网·www.751com.cn

2. A corrugated paper installation according to claim1, including two setting devices for coarse setting and free setting of said carrier bands, and a further coupling between the setting device for free setting and the second input of said planetary gear stage.
