PREAMBLE TO THE DESCRIPTION The following specification particularly describes the invention and the manner in which it is to be performed : - ENGLISH TRANSLATION VARIFICATION CERTIFICATE u/r. 20(3)(b) I, Mr. HIRAL CHANDRAKANT JOSHI, an authorized agent for the applicant, MAN ROLAND DRUCKMASCHINEN AG do hereby verify that the content of English translation of certified German Priority claiming 10 2007 012945.0 dated 14th March 2007 thereof is correct and complete. The invention concerns a folding unit of a web-fed printing machine in accordance with the preamble of Claim 1. The DE 102 59 655 B3 discloses a sheet combining device of a printing machine, which is disposed between a longitudinal folding device and a horizontal folding device of a folding unit of a printing machine. The longitudinal folding device of the folding unit disclosed therein encompasses two formers, whereby print substrate webs fed into the respective former as sheet in the area of each former are slit in partial sheets through a longitudinal slitter assigned to the respective former. A sheet comprising partial webs exits from each former, whereby one sheet composed of partial webs, which exits one of the two formers, is divided into two partial sheets composed of partial webs, in accordance with DE 102 59 655 B3. The former of these two partial sheets is conveyed over a stapler, the latter of these two partial sheets is combined with the sheet composed of partial webs exiting the other former, without these partial webs reaching the area of the stapler. The folding unit of DE 102 59 655 B3, thus, requires two formers in the range of the longitudinal folding device, whereby one sheet composed of partial webs, which exits one of the two formers, can be divided into two partial sheets composed of partial webs. Such a folding unit has the disadvantage of restricted flexibility as well as restricted production possibilities. Furthermore, the same is laborious and expensive, since two formers are required in the area of the longitudinal folding device. From this point of departure, the invention at hand is based on the problem of creating a novel folding unit of a web-fed printing machine. This problem is solved by means of a folding unit of a web-fed printing machine in accordance with Claim 1. In accordance with the invention, the longitudinal folding device demonstrates only one former, whereby print substrate webs fed into the former as sheet are slit into partial webs through longitudinal slitting by means of a longitudinal slitter assigned to the former or through minimum one longitudinal slitter, respectively assigned to minimum one print substrate web each of the sheet. The said partial webs exit the former as partial sheets and that the sheet exiting the former can be divided into minimum three partial sheets downstream from the former and upstream from the transverse folding unit, whereby one stapler is respectively assigned to minimum one of the partial sheets. The folding unit in accordance with the invention demonstrates one single former in the longitudinal folding device. Hereby, costs can be reduced. The sheet exiting the single former can be divided into minimum three partial sheets, whereby one stapler respectively is assigned to minimum one of the partial sheets, preferably to more than one of the partial sheets. Hereby, flexibility and production possibilities of the folding unit can be enhanced. The partial sheets can be combined downstream of the stapler or each stapler and upstream of the transverse folding unit. Preferably one stapler each is assigned to minimum two partial sheets. Preferred advancements of the inventions can be derived from the sub-claims and the following description. Execution examples of the invention have been described in detail by means of the drawing, without being constrained by it. Hereby, Fig. 1 illustrates a folding unit of a web-fed printing machine in accordance with the invention as per a first execution example; Fig. 2: A folding unit of a web-fed printing machine in accordance with the invention as per a second execution example; Fig. 3: A folding unit of a web-fed rotary printing press in accordance with the invention as per a third execution example; Fig. 4: A folding unit of a web-fed rotary printing press in accordance with the invention as per a fourth execution example; Fig. 5: A folding unit of a web-fed rotary printing press in accordance with the invention as per a fifth execution example; and Fig. 6: A folding unit of a web-fed rotary printing press in accordance with the invention as per another execution example. In the following, the invention at hand has been described in greater detail with reference to Fig. 1-6, whereby Fig. 1-6 show schematic representations of preferred execution examples of a folding unit of a web-fed rotary printing machine in accordance with the invention. The folding unit of Fig. 1 encompasses a longitudinal folding unit 10 as well as a transverse folding unit 11. The longitudinal folding unit 10 encompasses one single former 12, whereby a sheet 13 composed of several print substrate webs stacked one over the other is fed into the former 12. In the area of the former 12, the sheet composed of print substrate webs fed into the former 12 is divided into partial webs through longitudinal slitting by means of a longitudinal slitter assigned to the former 12 and not shown in the figure, whereby a sheet 14 composed of partial webs exits the former 12. When, as shown in Fig. 1, a longitudinal slitting device is assigned to the former 12, the longitudinal slitting of all print substrate webs of sheet 13 takes place on former 12. In this case, the sheet 14 exiting the former 12 encompasses a quantity of 2xm partial webs, when the sheet 13 fed into the former 12 is composed of a quantity m of print substrate webs. Alternatively, it is also possible, that one longitudinal slitting device is respectively assigned to minimum one print substrate web of sheet 13 upstream of the former 12. In this case, the print substrate webs of stream 13 can be divided individually through longitudinal slitting, whereby a provision can be made that only a few of the print substrate webs are divided into partial webs through longitudinal slitting. The partial webs exiting the former 12 of the longitudinal folding device 10 are conveyed to the transverse folding device 11, whereby copies are separated from the partial webs by means of transverse slitting and transverse folds are made in these copies in the range of the transverse folding device 11. In accordance with Fig. 1, the transverse folding unit 11, thus, encompasses a cutting blade cylinder 15 in order to separate copies from the partial webs through transverse slitting. Furthermore, the transverse folding device 11 encompasses a folding blade cylinder 16 as well as a folding jaw cylinder 17, in order to make transverse folds in the copies separated through transverse slitting. In the spirit of the invention at hand, the sheet 14 exiting the sole former 12 of the longitudinal folding device 10 is divided into minimum three partial webs upstream of the transverse folding device 11, seen from the transport direction of the partial webs and/or print substrate webs, whereby one stapler is respectively assigned to minimum one of the partial webs. In the execution example of Fig. 1, the sheet 14 composed of partial webs and exiting the former 12, is divided into three partial webs 18,19 and 20, whereby a stapler 21 is respectively assigned to each of the partial webs 18, 19 and 20. In the range of the staplers 21, the respective partial webs 18, 19 and 20 are combined with each other e.g. through saddle wire stapling. As can be derived from Fig. 1, the partial webs 18, 19 and 20 are combined once again after passing by the staplers 21 upstream of the transverse folding device 11. Thus, we have three stapled products, lying one within the other in the so-called double production. In the so-called collective production, we have up to 6 stapled products lying one within the other. In the sheet guide of the partial sheets 18,19 and 20, there are devices, for register-aligned combining and/or unifying of the partial sheets 18,19 and 20. The number of partial webs per partial sheet 18,19 and 20 is freely selectable. Thus, it is, e.g., possible that each of the partial sheets 18,19 and 20 demonstrates the same number of partial webs. Likewise, it is possible that each of the partial sheets 18,19 and 20 is distinctive in respect of the number of partial webs. The execution example of Fig. 2 is different from the execution example of Fig. 1 in that a stapler 21 is not assigned to each of the partial sheets 18,19 and 20, but only to the two external partial sheets 18 and 20 of the three partial sheets. As mentioned earlier, it is possible that the print substrate webs of the sheet 13 are individually separable through longitudinal slitting. Thus, there can be a provision, e.g., in the context of the execution example of Fig.2, that merely the external partial webs 18, 20 travelling over the staplers 21 encompass partial webs generated through longitudinal slitting in tabloid form, whereas, in contrast, the middle partial sheet 19 encompasses unseparated print substrate webs in broadsheet format. Besides, it is possible in both the execution examples of Fig 3-6 that one partial sheet or even several partial sheets encompass/es unseparated print substrate webs in broadsheet format. In the execution example of Fig. 3, a stapler 21 is assigned to merely the middle partial sheet 19 out of the three partial sheets. In the execution examples of Fig. 1-3, the sheet 14 exiting the sole former 12 can be divided into three partial sheets 18, 19 and 20. Fig. 4, 5 and 6, on the other hand, show execution examples, wherein the partial sheet 14 exiting the sole former 12 of the longitudinal folding device 10 can be divided into five partial sheets 18,19,20,22 and 23. In the execution example of Fig. 4, a stapler 21 is respectively assigned to the external partial sheets 18 and 20 and the middle partial sheet 19. On the other hand, in the execution example of Fig. 5, one stapler 21 each is assigned to the two partial sheets 22 and 23, which respectively run between the middle partial sheet 19 and one of the external partial sheets 18 and/ or 20. In the execution example of Fig. 6, a stapler 21 is respectively assigned to the external partial sheets 18 and 20, the middle partial sheet 19 and the partial sheet 23 running between the partial sheets 19 and 20. At this point, it may be pointed out that the division of the sheet exiting the former into three or five partial sheets is of purely exemplary nature. Thus, there can even be four or more than five partial sheets. In the spirit of the invention at hand, the sheet exiting the sole former is divided into minimum three partial sheets. One stapler each is respectively assigned to minimum one of these partial sheets, preferably min. two partial sheets.

In the following, the invention at hand has been described in greater detail with reference to Fig. 1-6, whereby Fig. 1-6 show schematic representations of preferred execution examples of a folding unit of a web-fed rotary printing machine in accordance with the invention.
The folding unit of Fig. 1 encompasses a longitudinal folding unit 10 as well as a transverse folding unit 11. The longitudinal folding unit 10 encompasses one single former 12, whereby a sheet 13 composed of several print substrate webs stacked one over the other is fed into the former 12. In the area of the former 12, the sheet composed of print substrate webs fed into the former 12 is divided into partial webs through longitudinal slitting by means of a longitudinal slitter assigned to the former 12 and not shown in the figure, whereby a sheet 14 composed of partial webs exits the former 12. When, as shown in Fig. 1, a longitudinal slitting device is assigned to the former 12, the longitudinal slitting of all print substrate webs of sheet 13 takes place on former 12. In this case, the sheet 14 exiting the former 12 encompasses a quantity of 2xm partial webs, when the sheet 13 fed into the former 12 is composed of a quantity m of print substrate webs.
Alternatively, it is also possible, that one longitudinal slitting device is respectively assigned to minimum one print substrate web of sheet 13 upstream of the former 12. In this case, the print substrate webs of stream 13 can be divided individually through longitudinal slitting, whereby a provision can be made that only a few of the print substrate webs are divided into partial webs through longitudinal slitting.

The partial webs exiting the former 12 of the longitudinal folding device 10 are conveyed to the transverse folding device 11, whereby copies are separated from the partial webs by means of transverse slitting and transverse folds are made in these copies in the range of the transverse folding device 11. In accordance with Fig. 1, the transverse folding unit 11, thus, encompasses a cutting blade cylinder 15 in order to separate copies from the partial webs through transverse slitting. Furthermore, the transverse folding device 11 encompasses a folding blade cylinder 16 as well as a folding jaw cylinder 17, in order to make transverse folds in the copies separated through transverse slitting.
In the spirit of the invention at hand, the sheet 14 exiting the sole former 12 of the longitudinal folding device 10 is divided into minimum three partial webs upstream of the transverse folding device 11, seen from the transport direction of the partial webs and/or print substrate webs, whereby one stapler is respectively assigned to minimum one of the partial webs.
In the execution example of Fig. 1, the sheet 14 composed of partial webs and exiting the former 12, is divided into three partial webs 18,19 and 20, whereby a stapler 21 is respectively assigned to each of the partial webs 18, 19 and 20. In the range of the staplers 21, the respective partial webs 18, 19 and 20 are combined with each other e.g. through saddle wire stapling. As can be derived from Fig. 1, the partial webs 18, 19 and 20 are combined once again after passing by the staplers 21 upstream of the transverse folding device 11.
Thus, we have three stapled products, lying one within the other in the so-called double production. In the so-called collective production, we have up to 6 stapled products lying one within the other.
In the sheet guide of the partial sheets 18,19 and 20, there are devices, for register-aligned combining and/or unifying of the partial sheets 18,19 and 20.

Thus, there can be a provision, e.g., in the context of the execution example of Fig.2, that merely the external partial webs 18, 20 travelling over the staplers 21 encompass partial webs generated through longitudinal slitting in tabloid form, whereas, in contrast, the middle partial sheet 19 encompasses unseparated print substrate webs in broadsheet format. Besides, it is possible in both the execution examples of Fig 3-6 that one partial sheet or even several partial sheets encompass/es unseparated print substrate webs in broadsheet format.
In the execution example of Fig. 3, a stapler 21 is assigned to merely the middle partial sheet 19 out of the three partial sheets.
In the execution examples of Fig. 1-3, the sheet 14 exiting the sole former 12 can be divided into three partial sheets 18, 19 and 20. Fig. 4, 5 and 6, on the other hand, show execution examples, wherein the partial sheet 14 exiting the sole former 12 of the longitudinal folding device 10 can be divided into five partial sheets 18,19,20,22 and 23.
In the execution example of Fig. 4, a stapler 21 is respectively assigned to the external partial sheets 18 and 20 and the middle partial sheet 19. On the other hand, in the execution example of Fig. 5, one stapler 21 each is assigned to the two partial sheets

22 and 23, which respectively run between the middle partial sheet 19 and one of the external partial sheets 18 and/ or 20. In the execution example of Fig. 6, a stapler 21 is respectively assigned to the external partial sheets 18 and 20, the middle partial sheet 19 and the partial sheet 23 running between the partial sheets 19 and 20.
