The funnel construction 01 shown in FIG. 1 has at least one funnel plane with two juxtaposed, in particular fixed-format, formers A, B; C, D on. These are either in pairs or individually laterally movable so that by applying a fifth-wide sub-string (see Fig. 5) also five-sided wide webs with one or both of the fixed formers A; B; C; D can be processed. This is especially true for products that require variable web widths.

Advantageously, two such funnel planes, each with two such juxtaposed folding funnels A, B; C, D provided.

The hopper assembly 01 is associated with at least one folder F1 or folding unit 01, which may be formed for example as a double folder with two folding cassettes F1A and F1 B.

In one embodiment, the formers A; B; C; D z. B. in each case an effective width b in their casserole area for the incoming web, which is half of an effective width b02 of a funnel structure 01 upstream printing cylinder 02, z. B. a forming and / or a transfer cylinder 02, corresponds (Fig. 2).

In another embodiment, the formers A; B; C; D z. B. each have an effective width in their ramp area for the incoming web, the two standing pages of a standard product in the stationary newspaper format, z. B. two newspaper pages in broadsheet format corresponds (see, for example, Fig. 3). Ie. the effective width of the former A; B; C; D corresponds z. B. two juxtaposed printing forms in newspaper format, especially in broadsheet format. In this case, the effective width b02 of the forme cylinder 02 can be greater than four juxtaposed printing forms in the newspaper format. The printed pages in the newspaper format, in particular the standard format, here have, for example, a width of 12.5 inches.

In Fig. 3, the printing cylinder 02 (in particular all printing cylinders of a printing unit or a printing unit 03) has a greater effective width b02 than four newspaper pages above, in particular an effective width b02 of five newspaper pages on. The printed with four sides or four newspaper pages wide web B1 passes through the printing unit 03 in a plane of symmetry S center, is longitudinally cut by a longitudinal cutting device with at least one - in particular transversely movable - knife M1 in the middle before the resulting part webs the formers A; B; C; D be supplied. The formers A; B; C; D are in a symmetrical to the symmetry plane S position, z. B. basic position. The width b1 of the web B1 is z. B. 50 inches. The production shown in Fig. 3 thus z. B. is a newspaper production with a four-page wide web B1, with four newspaper pages next to each other (eg., Each 12.5 inches wide) printed (short: 4/4), dar. None of the partial webs is turned, ie all are in straight ahead the respective former A; B; C; D supplied. The section through the longitudinal cutting device (see knife M1) can also immediately before running onto the former A; B; C; D, for example, take place on a hopper inlet roller, not shown.

In Fig. 4, a web B2 passes through a larger width b2, z. B. 62.5 inch, the printing unit 03, in which it z. B. is printed side by side with five printed pages. This results in a maximum increase of the possible number of pages in newspaper production to 125% in comparison to a maximum page number producible with a four-page wide rotation. The web B2 is then passed through at least two knives M1; M2 (or a longitudinal cutting device with at least two knives M1, M2) cut into three partial webs, wherein two partial webs are each two newspaper pages wide, and a partial web a newspaper page wide. In the example of Figure 4, the three partial webs by the two transversely to the web running direction spaced knife M1; M2 in the web before a turning bar assembly W cut longitudinally. In only dashed representation variant of the one of the two cuts, z. B. the one between the two each two-sideways partial webs, even immediately before emergence on the former A; B; C; D, for example, take place on a hopper inlet roller, not shown. One partial web then runs as far as the funnel inlet roller as a four-side-wide partial web (4/5 web) and the other as a one-side-wide partial web (1/5 web).

The two funnels A; B; C; D are placed in an eccentric position in which they are offset by an offset V, z. B. by a half newspaper page width, are moved across the above-mentioned basic position transversely to the incoming web B01. The only one Newspaper side wide partial web is turned over a turning bar pair of a turning bar assembly W on the flight of one of the other two partial webs and with this together the corresponding former A; B; C; D supplied.

Preferably, the funnels A; B; C; D of the two funnel groups are moved independently of each other laterally, so that printed a subset of the webs to be printed with five pages in width and on accordingly shifted from the basic position funnel A; B; C; D a hopper level can be performed and printed the remaining webs with four sides in the width and located in the base position funnel A; B; C; D the other funnel level can be performed. This can result in a cost savings when the four-sided wide webs are printed by means of easily exchangeable individual plates.

The production shown in Fig. 4 thus z. B. is a newspaper production with a five-page wide web B1, which is printed with five newspaper pages side by side (eg., Each 12.5 inches wide) (short: 5/5) is, A 1/5 partial web is turned while the other two partial webs in the straight-line run the respective - correspondingly positioned - former A; B; C; D is supplied.

Fig. 5 shows an embodiment, wherein a web B3, possibly with one of the aforementioned widths b1; b2 different width b3, with printed pages in tabloid format, that is printed with horizontal printed pages. For example, a 51-inch wide web B3 with three side-by-side tabloid sides with sides of z. B. 17 inches printed. The funnel construction 01 according to FIG. 5 has, in addition to the other two funnels A; B; C; D another folder E (additional funnel E) on which z. B. is wider than the former. It has, for example, a width b3, which corresponds to two printed pages in tabloid format, for. B. a width b3 of 34 inches. For example, web B3 is cut into a two-thirds and one-thirds wide web. These Now be offset laterally by two turning bar pairs of a turning bar assembly W and guided on the additional funnel E. However, it is also possible to use two knives M1; M2 z. Example, a longitudinal cutting device three third part widths webs be generated, which are then fed to the additional hopper E three turning bar pairs of a turning bar assembly W then. The additional funnel E, for example, has a greater effective width b 'than the other formers A; B; C; D.

With the embodiment according to FIG. 5, so-called tabloid or quarter-folded products with variable side widths of 5.5 to 8.5 inches can thus be produced. Depending on the page height to be generated (eg between 11-17 inches), three to five printed pages (three printed pages next to one another in FIG. 5) can be produced side by side on the web B3.

6 shows an example of a printing machine with four reelstands R01 to R04, three printing towers (eg each having at least four printing locations on both sides), the funnel structure 01 and the folding apparatus F1. The superstructure has z. B. two turning towers, each with at least two turning bar pairs of a turning bar assembly W, advantageously three turning bar pairs, on. On at least one of the printing towers D01 to D03 can be arranged an additional printing unit with an additional pressure point per web page. The three printing towers D01 to D03 are traversed in the illustration of FIG. 6 of four tracks. Alternative production possibilities are set forth in the table under the printing press of FIG. 6, the second and fourth line products corresponding to a web B1 according to FIG. 3 four webs B1, the first and third line products corresponding to a web B2 having a width of five pages According to Fig. 4, the fifth to seventh line products corresponding to a three lying pages in tabloid width B3 in FIG. 5 and the eighth line to the product corresponding to a web B3 modified smaller tabloid product, wherein five lying tabloid sides a smaller length, z. B. 11 inches long, side by side on a 55 inch wide web. For example, with 40/30 etc. specified Number of pairs indicates how many print pages can be produced in total with this production (here eg 40 pages), and how many of them can be printed in two-sided four-color printing (here eg 30). The short form "five wide" etc. means "five pages of the specified format wide".

In further Ausführungsbespielen Fig. 7 to 10 show superstructures or funnel structures for variable product design with a default for four printed pages of a first format in the web width designed printing machine (with correspondingly wide printing unit or forme cylinder 02) for the pressure of three compared to the standard print page wider printed pages of a different format from the first format. The printed pages can in the latter case z. B. less than one-third of a maximum in the printing unit printable width (b02) or equal to one third of this width (b02). However, it is larger than a quarter of the standard width for printing four standard pages of the first size side by side.

The printing press can now be operated side by side in an operating situation with four printed pages of the first format side by side or with three printed pages of the second format side by side.

In the upper part of the figures, a page layout on a web B2 for the standard case of four printed pages (strand Sa, Sb, Sc, Sd), and directly below a web B3 for three broader pages (strand S1 to S3) is shown. Downstream follows a funnel structure 01 with at least two adjacent funnels A; B. The two adjacent funnels A; B in FIG. 7 each have an effective width b in the run-up area for the web, which corresponds in each case to half the maximum web B2 to be printed, that is to say two page widths in the standard format when printing on four sides. An effective width (b / 2) of a funnel edge of this two-flank funnel A; B thus corresponds to a page width in standard format - in the example substantially one quarter of the effective width b02 of the forme cylinder 02 or the maximum width of the web to be printed.

The two funnels A; B is a wider addition judge (E), or as shown a "half funnel" F associated with only one funnel edge f. In the embodiment according to FIG. 7, in the case of three-sided operation (ie when printing three broader printing sides next to one another), the web is cut into three partial webs and each of the partial webs offset in parallel by a turning bar arrangement, so that they lie on a flank f of the wider funnel E or ., the longer flank f of the half funnel F accumulate. The effective width bf of this flank f, short flank width (ie projection of the effective width on the width of the incoming part web) of the hopper E, in particular of the half hopper F is designed to be greater than a quarter of the maximum width to be printed b02 and corresponds to at least one strand width one of the three sub-webs or substantially equal-width strands S1, S2, S3. The web B3 is thus in one operating situation by two knives M1; M2 in three - e.g. cut equal width - partial webs (strands S1 to S2), each of the three strands via a pair of turning bars W laterally offset to the broader edge f, and led together on this flank f. In the other - e.g. standard - operating situation, the railway B2 by z. For example, a knife M1 is longitudinally cut longitudinally, and the two resulting-e.g. in each case two standard print pages wide - partial webs in straight-line design on the two funnels A; B guided. In principle, one of the two partial webs can also be guided via one of the turning devices W onto the other partial web and jointly onto one of the two funnels A; B are led. It is advantageous if at least one of the turning devices W are formed with turning bars of a length which corresponds to at least half the effective width b02 of the forme cylinder 02, or at least half of the maximum web width to be printed, in projection onto the incoming part web.

The half hopper F may be in the manner of a pressure medium, eg compressed air, inflated turning bar - eg without an additional hopper plate - be formed.

In FIG. 8, the partial webs run on an edge f of one of the two funnels A '; B 'on and are on corresponding turning devices and possibly additionally falls (eg, because here the offset of the third sub-web is very low) aligned with this flank f. Funnels A '; B 'remain here z. B. compared to standard production stationary. At least one of the two funnels A '; B 'is asymmetric with respect to its effective funnel edges, d. H. he points - e.g. on a side facing the outside of the machine - a longer effective edge f (or larger width bf of the projection), eg. B. bf greater than a width of a printed page in the standard format. The funnel A '; B 'is for this purpose e.g. asymmetrically formed, d. H. he has a longer edge f and a side edge of the standard pressure side corresponding shorter edge (on the machine inside). In Fig. 7 and 8 thus z. B. laterally offset all three sub-webs.

As a funnel edge here are the inclined to the web running direction legs of the substantially triangular funnel A; B; A '; B 'understood. The leg regions of the funnel A 'running obliquely to the direction of web travel; B 'in Fig. 8 are different in length. In the example of the "half" funnel F, the asymmetry is designed such that the length of the one leg becomes zero.

To at least partially avoid the lateral displacement, according to FIG. 9 at least one of the funnels A '; B ', especially the hopper B' provided for the third partial webs; movable transversely to the web running direction. As shown in FIG. 9, one partial path (here on the left) can travel straight ahead along the longer flank f of the funnel B 'which has moved inward, and the middle and right partial path can likewise be aligned with this flank f via turning devices. If the funnel B 'is driven even further inward, one or more partial webs can be moved to the center of the funnel in an unillustrated embodiment and can therefore be longitudinally folded. The same result can be achieved if a partial web to be turned is aligned not on the flank, but on the funnel tip.

On the other hand, one or more of the tracks can not on the flank, but exactly between two funnels A '; B 'are driven, but this must then be cut before. However, both funnels A '; B '- e.g. together - be designed to be movable transversely to the web running direction in the same direction. In this case, in each case only a wider flank f with a non-turned wider sub-web can be brought into flight.

Is the funnel A '; B 'designed to be movable inwardly, the two funnels A'; B 'either slightly offset in height so that they do not interfere with each other, or are in the center of the hopper A' directed to the machine center; B 'optionally attachable or removable lugs provided. These are removed in the case of the collision and re-scheduled or unfolded for standard production.

In an embodiment shown in Fig. 10 z. B. both funnels A '; B 'moves in the direction of the machine center that without turning the one outer part of the web on the outer longer edge f of a funnel B' and the other outer part of the web on the outer longer edge f of the other funnel A 'is performed. The middle sub-path can then either on flank f of one or the other funnel A '; B 'turned or aligned.
