Definitions

• the invention relates to a funnel structure and a printing unit of a web-fed rotary printing press according to the preamble of claim 1 or 17.
• DE 32 37 504 C2 shows two formers with an additional third former, at least one longitudinal cutter and two turner bars.
• the DE 101 63 209 B4 is an arrangement with two juxtaposed folders and each one to this in the vertical direction staggered effetfalztrichter to remove, the funnel structure is arranged after at least one printing unit of a printing press and productions for a certain number of stationary newspaper pages and lying newspaper pages in tabloid format.
• WO 2005 / 105447A1 discloses a funnel construction with a group of three folding funnels of a certain width arranged in the same funnel plane. In one embodiment, this group of three funnels is laterally associated with an additional former of greater width. In another embodiment, this group of three funnels on a different plane is a group of two additional larger width bins assigned.
• the invention has for its object to provide a funnel structure and a printing unit of a web-fed rotary printing machine with increased product variability.
• newspaper articles and / or magazine products can also be produced in a fixed-format newspaper format and / or variably-sized tabloid or quarterfold products.
• Fig. 1 shows an embodiment of a funnel structure
• Fig. 2 is a schematic representation of a forme cylinder

• Fig. 4 shows a second embodiment of a production by means of at least two juxtaposed former
• FIG. 5 shows a third embodiment for a production by means of at least two juxtaposed, and an additional third former
• Fig. 6 shows an embodiment of a printing machine with tabular representation of production alternatives.
• 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.
• the two funnels here in the same direction - and especially not necessarily opposite directions - laterally movable.
• the hopper assembly 01 is associated with at least one folder F1 or folding unit, which may be formed for example as a double folder with two folding cassettes F1 A and F1 B.
• the formers A; B; C; D z. B. each have an effective width b in their casserole area for the incoming web, which is half of an effective width bO2 of a funnel structure 01 upstream printing group cylinder 02, z. B. a forming and / or a transfer cylinder 02, corresponds (Fig. 2).
• 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.
• the effective width bO2 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.
• the printing cylinder 02 (in particular, all the printing unit cylinder of a printing unit or a printing unit 03) has a greater effective width bO2 than four o.g. Newspaper pages, in particular an effective width bO2 of five o.g. 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 divided by a - in particular transversely movable - longitudinal cutting 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, d. H. all are in straight ahead the respective former A; B; C; D supplied.
• the section through the longitudinal cutting device M1 can also immediately before running onto the former A; B; C; D, for example, take place on a hopper inlet roller, not shown.
• 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 productions 125% compared to a maximum page number that can be produced with a four-page wide rotation.
• the web B2 is then passed through at least two longitudinal cutting devices M1; M2 (or a longitudinal cutting device with at least two knives) cut into three sub-webs, wherein two sub-webs are each two newspaper pages wide, and a sub-web a newspaper page wide.
• M1 longitudinal cutting devices
• the three partial webs are separated by the two longitudinal cutting devices M1; M2 in the web before a turning bar assembly W cut longitudinally.
• the 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 half a newspaper page width, compared to the o. G. Basic position transverse to the incoming web B01 - in particular in the same direction - to be moved.
• the only one newspaper page 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.
• 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.
• 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.
• the at least two formers A; B; C; D are thus optionally in a symmetrical to a plane of symmetry S of the printing unit 03 and the printing machine position and in a position offset by half a newspaper page position can be brought.
• the plane of symmetry in this case runs perpendicular to the axis of rotation of the printing cylinder 02 and divides this to half its effective length.
• a length of the printing cylinder 02 thus corresponds z.
• the printing cylinder 02 is therefore significantly larger than 2n, and less than 3n broadsheet pages, ie its width is z. Greater than 2.1 * n newspaper pages and less than 1.9 * (n + 1) newspaper pages in broadsheet format, where n represents a natural number, ie ne N.
• Funnels A; B; C; D of this level are thus movable by half a newspaper page width of the broadsheet format.
• the movable funnels A; B; C; D for example, formed laterally movable at least by a quarter of this funnel width.
• 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.
• 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.
• 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.
• web B3 is cut into a two-thirds and one-thirds wide web. These are now offset laterally by two turning bar pairs of a turning bar arrangement W and guided on the additional funnel E.
• the additional funnel E has a greater effective width b 'than the other formers A; B; C; D.
• so-called tabloid or quarter-folded products with variable side widths of 5.5 to 8.5 inches can thus be produced.
• the side height to be generated for example, between 1 1 - 17 inches
