There are web fed rotary printing machines known, which consists of printing press subsystems, wherein the printing press sub-systems guide continuous printed material via at least one common folding unit. As printing press sub-system ail technical means or modules of a web fed rotary printing machine should be considered, which are responsible for printing the continuous printing rolls and for conveying of continuous printing rolls including reversing same in the direction of a common folding unit. As per the state of technology printing press sub-systems are differentiated with respect to the same printable print pages, particularly with respect to print pages according to the print cylinders in the longitudinal direction next to each other and in circumferential direction behind each other on printing material. In case of a 2/1 printing press subsystem with the respective print cylinders in longitudinal direction or axial direction two print pages are printable next to each other and in circumferential direction one print page on a printing material. With a 4/2 printing machine sub-system in longitudinal direction four print pages are printable next to each other and in circumferential direction two print pages one after the other on a printing material. To generalize the above concept with an X/Y printing press sub-system in longitudinal direction X print pages can be printed next to each other and in circumferential direction Y print pages one after the other. Common printing press sub-systems are 2/1,3/1,4/1,2/2,3/2,4/2 and 6/2 printing press sub-systems. In the sense of this present invention it is possible, to combine benefits of printing press sub-systems with each other, which are built-up differently with respect to printable print pages, in a web fed rotary printing machine. Thus, for example, printing press subsystems have the advantages with respect to variability of path width, which are characterized by small number of printable print pages next to each other in longitudinal direction vis-a-vis printing press sub-systems, which print a larger number of print 2 pages next to each other on a printing material roll in longitudinal direction. Printing press sub-systems, which print in longitudinal direction a larger number of print pages next to each other on a news print roll, have advantages in view of page capacity. Printing press sub-systems, which print - seen in circumferential direction - only one print page on a news print roll, have advantages with respect to achievable product variety vis-a-vis printing press sub-systems, which print in circumferential direction several print pages one after the other on a news print roll. With the invention based web fed rotary printing machine the individual advantages of individual printing press subsystems can be combined with each other. Preferably the printing presses of variously built-up printing press sub-systems are built-up in such a different manner that in longitudinal direction and/ or in circumferential direction of the respective printing cylinders a different number of print pages can be printed. As per advantageous further development of the present invention the printing press sub-systems are built-up so differently that in the printing press sub-systems the news print rolls can be printed with different printing processes. As per advantageous further development of the present invention the printing press sub-systems are built-up so differently that in the printing press sub-Each of the printing press sub-systems 11, 12 has further a path guiding unit for conveying or moving unprinted as well as printed news print rolls 13,14 or 15 and has one reversing rodding unit 20 or 21, with the help of which printed news print rolls can be fed to the folding unit 16. In the sense of the present invention the printing modules of the printing press subsystems 11 and 12 of the web fed rotary printing machine 10 are built-up in so different manner that in longitudinal direction and/or in circumferential direction of the respective printing cylinder a varying number of print pages can be printed, so that the 3 printing press sub-systems differ with respect to number of print pages printable on the news print rolls. As per the first alternative the printing modules of the printing press sub-systems differ in a manner that in longitudinal direction of the respective printing cylinders a varying number of print pages can be printed, in circumferential direction, however, an identical number of print pages can be printed. As per the second alternative the printing modules of the printing press sub-systems differ in a manner that in circumferential direction of the respective printing cylinders a varying number of print pages can be printed, whereas in longitudinal direction the number of printable print pages is identical. As per a third alternative in longitudinal direction as well as in circumferential direction of the respective printing cylinders a varying number of print pages is printable on the printing material. In the cases, in which in the variously built-up printing press sub-systems in circumferential direction of the respective printing cylinders a varying number of print pages can be printed, the circumferences of printing cylinder in circumferential direction of larger printing cylinders are integral multiples of the circumference of the smallest print cylinder in circumferential direction. Further, in these cases the printing press subsystems are operated in the so-called straight operation (non-collated printing operation) and not in the so-called collect operation (collated printing operation). In a concrete execution form the printing press sub-system 12 is built-up as 4/2 printing press sub-system and the printing press sub-system 11 as 2/2 printing press sub-system. In this case, in the printing module towers 17 and 18 the each of the printing cylinders of the respective printing modules print in longitudinal direction four print pages next to each other and in circumferential direction two print pages each one after the other on the news print rolls 13 and 14. In the print module tower 19 the printing cylinders would print on the news print roll 15 in longitudinal direction two print pages next to each other and in circumferential direction two print pages one after the other. The web fed rotary printing machine 10 would then have under consideration of printing of front and back side of the news print rolls a capacity of 40 print pages. 4 Similarly, it is possible, that the printing press sub-system 12 is built-up as 6/2 printing press sub-system and the printing press sub-system 11 as 2/2 printing press sub-system, wherein the web fed rotary printing machine has then a capacity of 56 print pages. Similarly, the printing press sub-system 12 can be built-up as 4/1 printing press subsystem and the printing press sub-system 11 as 2/1 printing press sub-system, whereby a capacity of 12 print pages is there for the web fed rotary printing machine. In the sense of the present invention the printing press sub-systems 11 and 12 of the web fed rotary printing machine 10 can be further built-up in such a manner that the news print rolls in the respective printing press sub-systems are printable with different printing processes. Thus, the printing modules of the printing module towers 17 and 18 of the printing press sub-system 12 can for example print in offset, whereas in the print modules of the printing module tower 19 of the printing press sub-system 11 the news print roll is printed in the digital print. Further, more combinations of different printing processes are possible, thus, for example, combinations between offset printing and flexo printing or even digital printing and flexo printing. Further, in the printing press sub-systems 11 and 12 different news print materials which means materials of different features can be printed. Fig. 2 shows a second execution example of an invention based web fed rotary printing machine 22, which in turn consists of two printing press sub-systems 23 and 24. In the printing press sub-systems 23 and 24 news print rolls 25, 26 and 27 are printed, wherein the news print rolls 25 to 27 printed in the printing press sub-systems 23 and 24 are fed via reversing rodding units 28 and 29 to a common folding unit 30. In the sense of the present invention both the printing press sub-systems 23 and 24 of the web fed rotary printing machine 22 of Fig. 2 are built-up differently in such a way that in both the printing press sub-systems 23 and 24 news print rolls can be printed with a different number of print pages. The printing modules of the printing press sub-systems 23 and 24 can be so differently built-up that in longitudinal direction and/or in circumferential direction of the respective printing cylinders a varying number of print pages are 5 printable on the news print rolls 25, 26 and 27. In the execution example of Fig. 2 the printing modules of the printing press sub-system 23 are configured in form of two printing module towers 31 and 32. Whereas, in the printing press sub-system 24 there is only one printing module tower 33 available. Optionally, as shown in Fig. 2 with discontinuous line, however, also the printing press sub-system 24 has a second printing module tower 34 for printing of another news print roll 35. In the execution example of Fig. 2 the printing press sub-systems 23 and 24 further differentiate with the fact that in the printing press sub-systems 23 and 24 the printing color is applied with different color application procedure on the news print rolls. Thus in the printing press sub-system 23 the color application follows in the so-called cold set process and in the printing press sub-system 24 in the so-called heat set process. Heat set drying equipment of the printing press sub-system 24 are marked in Fig. 2 with reference numbers 36. In a concrete execution example the printing modules of the printing module towers 31 and 32 of the printing press sub-system 23 can be executed as so-called 6/2 printing modules for providing a 6/2 printing press sub-system, wherein with the respective printing cylinders in longitudinal direction next to each other six each and in circumferential direction one after the other two each print pages can be printed on the news print rolls 25 and 26 to be printed in the printing press sub-system 23. The printing modules of the printing module towers 27 and 34 of the printing press sub-system 24 can be executed as 2/2 print modules for providing a 2/2 printing press sub-system. Hereby, the advantages of 6/2 printing units with respect to page capacity can be combined with the advantages of 2/2 printing units with respect to heat set printing capability in a single web fed rotary printing machine. Further, in the execution example of Fig. 2 the printing press sub-systems 23 and 24 can differ with respect to printing process as well as the news print rolls to be printed. 6 In the execution examples as per Fig. 1 and 2 the news print rolls printed in the differently built-up printing press sub-systems are fed to a common folding unit. It may be noted that also two or more common folding units can be present. 7 Reference symbol list 10 Web fed rotary printing press 11 Printing press sub-system 12 Printing press sub-system 13 News print roll 14 News print roll 15 News print roll 16 Folding unit 17 Printing module tower 18 Printing module tower 19 Printing module tower 20 Reversing rodding unit 21 Reversing rodding unit 22 Web fed rotary printing press 23 Printing press sub-system 24 Printing press sub-system 25 News print roll 26 News print roll 27 News print roll 28 Reversing rodding unit 29 Reversing rodding unit 30 Folding unit 31 Printing module tower 32 Printing module tower 33 Printing module tower 34 Printing module tower 35 news print roll 36 Heat set drying equipment 8 WE CLAIM: 1.

PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed : -

Web Fed Rotary Press
The invention relates to a web fed rotary press as per the title of the claim 1.
There are web fed rotary printing machines known, which consists of printing press subsystems, wherein the printing press sub-systems guide continuous printed material via at least one common folding unit. As printing press sub-system ail technical means or modules of a web fed rotary printing machine should be considered, which are responsible for printing the continuous printing rolls and for conveying of continuous printing rolls including reversing same in the direction of a common folding unit.
As per the state of technology printing press sub-systems are differentiated with respect to the same printable print pages, particularly with respect to print pages according to the print cylinders in the longitudinal direction next to each other and in circumferential direction behind each other on printing material. In case of a 2/1 printing press subsystem with the respective print cylinders in longitudinal direction or axial direction two print pages are printable next to each other and in circumferential direction one print page on a printing material. With a 4/2 printing machine sub-system in longitudinal direction four print pages are printable next to each other and in circumferential direction two print pages one after the other on a printing material. To generalize the above concept with an X/Y printing press sub-system in longitudinal direction X print pages can be printed next to each other and in circumferential direction Y print pages one after the other. Common printing press sub-systems are 2/1,3/1,4/1,2/2,3/2,4/2 and 6/2 printing press sub-systems.
In the sense of this present invention it is possible, to combine benefits of printing press sub-systems with each other, which are built-up differently with respect to printable print pages, in a web fed rotary printing machine. Thus, for example, printing press subsystems have the advantages with respect to variability of path width, which are characterized by small number of printable print pages next to each other in longitudinal direction vis-a-vis printing press sub-systems, which print a larger number of print

pages next to each other on a printing material roll in longitudinal direction. Printing press sub-systems, which print in longitudinal direction a larger number of print pages next to each other on a news print roll, have advantages in view of page capacity. Printing press sub-systems, which print - seen in circumferential direction - only one print page on a news print roll, have advantages with respect to achievable product variety vis-a-vis printing press sub-systems, which print in circumferential direction several print pages one after the other on a news print roll. With the invention based web fed rotary printing machine the individual advantages of individual printing press subsystems can be combined with each other.
Preferably the printing presses of variously built-up printing press sub-systems are built-up in such a different manner that in longitudinal direction and/ or in circumferential direction of the respective printing cylinders a different number of print pages can be printed.
As per advantageous further development of the present invention the printing press sub-systems are built-up so differently that in the printing press sub-systems the news print rolls can be printed with different printing processes.
As per advantageous further development of the present invention the printing press sub-systems are built-up so differently that in the printing press sub-Each of the printing press sub-systems 11, 12 has further a path guiding unit for conveying or moving unprinted as well as printed news print rolls 13,14 or 15 and has one reversing rodding unit 20 or 21, with the help of which printed news print rolls can be fed to the folding unit 16.
In the sense of the present invention the printing modules of the printing press subsystems 11 and 12 of the web fed rotary printing machine 10 are built-up in so different manner that in longitudinal direction and/or in circumferential direction of the respective printing cylinder a varying number of print pages can be printed, so that the
3

printing press sub-systems differ with respect to number of print pages printable on the news print rolls.
As per the first alternative the printing modules of the printing press sub-systems differ in a manner that in longitudinal direction of the respective printing cylinders a varying number of print pages can be printed, in circumferential direction, however, an identical number of print pages can be printed. As per the second alternative the printing modules of the printing press sub-systems differ in a manner that in circumferential direction of the respective printing cylinders a varying number of print pages can be printed, whereas in longitudinal direction the number of printable print pages is identical. As per a third alternative in longitudinal direction as well as in circumferential direction of the respective printing cylinders a varying number of print pages is printable on the printing material. In the cases, in which in the variously built-up printing press sub-systems in circumferential direction of the respective printing cylinders a varying number of print pages can be printed, the circumferences of printing cylinder in circumferential direction of larger printing cylinders are integral multiples of the circumference of the smallest print cylinder in circumferential direction. Further, in these cases the printing press subsystems are operated in the so-called straight operation (non-collated printing operation) and not in the so-called collect operation (collated printing operation).
In a concrete execution form the printing press sub-system 12 is built-up as 4/2 printing press sub-system and the printing press sub-system 11 as 2/2 printing press sub-system. In this case, in the printing module towers 17 and 18 the each of the printing cylinders of the respective printing modules print in longitudinal direction four print pages next to each other and in circumferential direction two print pages each one after the other on the news print rolls 13 and 14. In the print module tower 19 the printing cylinders would print on the news print roll 15 in longitudinal direction two print pages next to each other and in circumferential direction two print pages one after the other. The web fed rotary printing machine 10 would then have under consideration of printing of front and back side of the news print rolls a capacity of 40 print pages.

Similarly, it is possible, that the printing press sub-system 12 is built-up as 6/2 printing press sub-system and the printing press sub-system 11 as 2/2 printing press sub-system, wherein the web fed rotary printing machine has then a capacity of 56 print pages. Similarly, the printing press sub-system 12 can be built-up as 4/1 printing press subsystem and the printing press sub-system 11 as 2/1 printing press sub-system, whereby a capacity of 12 print pages is there for the web fed rotary printing machine.
In the sense of the present invention the printing press sub-systems 11 and 12 of the web fed rotary printing machine 10 can be further built-up in such a manner that the news print rolls in the respective printing press sub-systems are printable with different printing processes. Thus, the printing modules of the printing module towers 17 and 18 of the printing press sub-system 12 can for example print in offset, whereas in the print modules of the printing module tower 19 of the printing press sub-system 11 the news print roll is printed in the digital print. Further, more combinations of different printing processes are possible, thus, for example, combinations between offset printing and flexo printing or even digital printing and flexo printing.
Further, in the printing press sub-systems 11 and 12 different news print materials which means materials of different features can be printed.
Fig. 2 shows a second execution example of an invention based web fed rotary printing machine 22, which in turn consists of two printing press sub-systems 23 and 24. In the printing press sub-systems 23 and 24 news print rolls 25, 26 and 27 are printed, wherein the news print rolls 25 to 27 printed in the printing press sub-systems 23 and 24 are fed via reversing rodding units 28 and 29 to a common folding unit 30. In the sense of the present invention both the printing press sub-systems 23 and 24 of the web fed rotary printing machine 22 of Fig. 2 are built-up differently in such a way that in both the printing press sub-systems 23 and 24 news print rolls can be printed with a different number of print pages. The printing modules of the printing press sub-systems 23 and 24 can be so differently built-up that in longitudinal direction and/or in circumferential direction of the respective printing cylinders a varying number of print pages are
5

printable on the news print rolls 25, 26 and 27.
In the execution example of Fig. 2 the printing modules of the printing press sub-system 23 are configured in form of two printing module towers 31 and 32. Whereas, in the printing press sub-system 24 there is only one printing module tower 33 available. Optionally, as shown in Fig. 2 with discontinuous line, however, also the printing press sub-system 24 has a second printing module tower 34 for printing of another news print roll 35.
In the execution example of Fig. 2 the printing press sub-systems 23 and 24 further differentiate with the fact that in the printing press sub-systems 23 and 24 the printing color is applied with different color application procedure on the news print rolls. Thus in the printing press sub-system 23 the color application follows in the so-called cold set process and in the printing press sub-system 24 in the so-called heat set process. Heat set drying equipment of the printing press sub-system 24 are marked in Fig. 2 with reference numbers 36.
In a concrete execution example the printing modules of the printing module towers 31 and 32 of the printing press sub-system 23 can be executed as so-called 6/2 printing modules for providing a 6/2 printing press sub-system, wherein with the respective printing cylinders in longitudinal direction next to each other six each and in circumferential direction one after the other two each print pages can be printed on the news print rolls 25 and 26 to be printed in the printing press sub-system 23. The printing modules of the printing module towers 27 and 34 of the printing press sub-system 24 can be executed as 2/2 print modules for providing a 2/2 printing press sub-system. Hereby, the advantages of 6/2 printing units with respect to page capacity can be combined with the advantages of 2/2 printing units with respect to heat set printing capability in a single web fed rotary printing machine.
Further, in the execution example of Fig. 2 the printing press sub-systems 23 and 24 can differ with respect to printing process as well as the news print rolls to be printed.

In the execution examples as per Fig. 1 and 2 the news print rolls printed in the differently built-up printing press sub-systems are fed to a common folding unit. It may be noted that also two or more common folding units can be present.
