DESCRIPTION OF THE PREFERRED EMBODIMENTS

The installation illustrated in FIG. 1 serves to pro- duce corrugated paper which is printed on one side. A paper web 2 is pulled off a roller carrier 1and is formed in a corrugated paper machine 3 to corrugated shape and here united with a paper web 4 coming from a roller carrier 5. The web 6 thus produced advances into a storage 7 and is pulled from there through the next- following parts of the installation without here under- going any further treatment. The storage 7 can also be omitted.

A paper web 9 travels from a roller carrier 8 into a storage 10 and from there via a pulled-off drive 11 into a printing machine 12 which has a plurality of inpidual printing stations 13, for example, twenty of them. The paper web 9 is here printed on its upper side by several of the printing stations 13.

The printed paper web 14 travels at the end of the printing machine 12 into a laminating station 15 where j( is united with the web 6 to form a corrugated paper web 18.

At the end of the installation there are provided pull- off devices 16 and longitudinal cutters 17; the longitudinal cutters 17 cut the corrugated paper web 18 length- wise according to the printed-on laterally adjacent numbers of pattern repeats. Transverse cutters 19 or rotary punches are also provided in order to cut the web transversely and to separate the inpidual cuts from the partial webs.

The installation according to FIG. 2 is basically similar, but here both sides of the corrugated paper web 18 are printed. The paper web 4 is pulled off the roller carrier 5 and supplied via the storage 7 and the drive 11 to the first part of the printing machine 12. Here, three printing stages 13 are illustrated. It is understood that the number thereof can be varied here also. These three printing stations 13 serve to differently color or print the paper web 4 in accordance with the pattern distribution. The paper web 4 is then supplied to the corrugated paper machine 3. The paper web 2 which forms the corrugation is pulled off the roller carrier 1. In the corrugated paper machine 3 the webs 2 and 4 are united with one another. The web 6 is obtained which is advanced through the storage 7 and the following aggregates up to the laminating station 15.

The paper web 9 is pulled off the roller carrier 8 and supplied via the storage 7 and a further pull-off drive 11 into the second part of the printing machine 12, where again a number of printing stations 13 is provided. Since here the outer side of the later cut is to be printed, a comparably larger number of printing stations is pro- vided, analogous to the installation in FFG. 1. The printed paper web 14 is united with the web 6 in the laminating station 15 and the corrugated paper web 18 is obtained which, just as in the embodiment of FIG. 1, is subpided by longitudinal cutters 17 and transverse cutters 19.

FIG. 3 shows an inpidual printing station 13 of the printing machine 12 in schematic view. The paper web 9 to be printed is passed between the guide rollers 20, 21, 22, 23, 24, 25, 26 and 27 through the printing station

The printing cylinder 28 is stationarily journaled. Oppositely it there is provided a counter-pressure cylinder 29 which can be pushed against or pushed away from the printing- cylinder 28. The printing cylinder 28 is embraced by the carrier band 30 which according to the length of the pattern and possibly the number of patterns can have a different length and carries the printing forms. Different support and tension rollers 31, 32, 33 are provided which are shiftably mounted in order to permit an accommodation to the respective lengths of the carrier band 30. The carrier band 30 is wider than the corrugated paper web and has in the projecting marginal areas perforations which serve for its drive. The drive means necessary for this are inpidually connectable with the machine drive for the entire installation. It is also possible to connect groups of printing stations 13 for joint operation. The printing forms on the carrier band 30 are inked via an inking station 34. A drying installation 35 is provided between the guide rollers 22 and 23.
