12 Examples of folding funnels of variable effective width.

In the figures, a part of a web-fed rotary printing press, in particular a newsprint printing machine, is shown schematically, wherein a web B has at least one printing unit which is shown only symbolically 01 , in particular a printing tower with a plurality of printing units, passes through and one or both sides by at least one printing cylinder 02 is printed, a so-called. Superstructure with at least one, at least one blade unit 03 having longitudinal cutting means and optionally a turning device with at least one pair of turning bars 04 passes through, and finally in the form of partial webs B1; B2 on a funnel construction 06 be guided. Instead of or in addition to the blade unit 03 or the first-mentioned longitudinal cutting device can downstream of the turning device directly in front of the funnel inlet, z. B. cooperating with a funnel inlet roller, at least one alternative or additional longitudinal cutting device with a blade unit 07 be provided. Although in the printing unit shown schematically 01 no transfer cylinders are shown, are the printing units 01 preferably designed as an offset printing units.

The funnel construction 06 has at least one funnel plane with a group of at least two juxtaposed formers 08 ; 09 , z. B. standard folding funnels 08 ; 09 on. These (at least two) standard folding funnels 08 ; 09 are preferably - in particular individually - formed laterally movable transversely to the web running direction and / or in its effective width b; b ', ie in its width b; b 'viewed in the ramp area transversely to the web running direction, changeable.

The effective width b; b 'the standard folding funnel 08 ; 09 are variable in a bandwidth, which comprises at least the two following widths b, b '. The larger, z. B. maximum, width b is equal to twice an even divider, z. B. 2/4 (= 1/2) or 2/6 (= 1/3) of the nominal width b02 of the upstream printing unit 01 or printing cylinder 02 , The smaller, z. B. minimum, width b 'then equal to twice an odd divider, z. B. 2/5 or 2/7, the nominal width b02 of the upstream printing unit 01 or printing cylinder 02 , Nominal width is understood here as the maximum width for which the printing unit 01 or the printing cylinder 02 designed. This also corresponds approximately to a maximum web width bB.

At least for the external standard funnels 08 ; 09 However, a funnel group does not require a variability of the effective width f, f 'of this funnel flank (funnel half) on both funnel flanks, but only on the side facing an adjacent funnel. Thus, for operation with the larger format F1, the width f corresponds to at least one funnel edge F of the standard funnel 08 ; 09 an even divisor, e.g. B. 1/4 or 1/6 of the nominal width b02 of the upstream printing unit 01 or printing cylinder 02 , And in the case of the smaller width of the funnel or the printing of the narrower format F2, the width f 'of the funnel edge F' then an odd divider, z. B. 1/5 or 1/7, the nominal width b02 of the upstream printing unit 01 or printing cylinder 02 ,

Is the printing press or the printing unit 01 in standard production, eg Standard newspaper production, adapted to print n (with even n, eg n = 4 or n = 6) print pages of a first format F1, e.g. B. newspaper pages in a first broadsheet format to print side by side on the web, so have the, for. B. a number of at least n / 2 juxtaposed standard funnels 08 ; 09 in standard operation, an effective width b with b = 2 / n · b02 (with n even, eg 2, 4, or 6, in particular even and n ≥ 4) or at least one funnel edge F with an effective width f = 1 / n · b02. In the alternative production, where side by side n + 1 printed pages of a second format F2, z. B. print pages of an at least narrower broadsheet format F2 or a tabloid format F2, are printed on the web B or are, so have the standard funnel 08 ; 09 a smaller effective width b 'with b' = 2 / (n + 1) * b02, or at least at least one funnel edge F 'of smaller width f' with f '= 1 / (n + 1) * b02.

D. h., In a case contributes as a forme cylinder 02 trained printing cylinder 02 on its lateral surface in the axial direction side by side print images of a total of n printed pages of one Formates F1 (or F1 ', see below), in particular one or more printing forms with print image templates of side by side n print pages of a format F1 (or F1', see below), and in the alternative production on its lateral surface in the axial direction side by side print images of a total of n + 1 printed pages of the other format F2 (or F2 ', see below), in particular one or more printing forms with printed image templates of juxtaposed total of n printed pages of the other format F2 (or F2', see below).

For the advantageous case that the printing press not only for printing with the two basically by the maximum nominal width 02 predetermined formats F1 and F2, but also for the production with smaller formats F1 '; F2 'is formed (variable web width), the standard funnel 08 ; 09 have a relation to the above width b 'even smaller effective width b''as the lower limit. Examples, once for a narrower standard production with a smaller format F1 'and once for an alternative production with a smaller format F2', are in the 7 and 8th exemplary for all 1 to 6 given examples given. In addition to the standard hoppers 08 ; 09 are then preferably also one or more blade units 03 ; 07 and / or one or more turning bars 04 transversely to the web running direction, advantageously remote-controlled, movable - in particular via the control station or even an automatic presetting system with regard to the planned production or used web width and the format F1 to be produced; F1 ';F2; F2 'positionable.

In an advantageous embodiment of the printing press, the superstructure has at least one pair of turning bars 04 on, which has a deflection effective length whose projection on the width of the incoming web B, B 'z. B. at least 3/5 (in a printing machine with n = 4 printed pages in standard format (F1) or 3/7 (in a printing press with n = 6 printed pages in the standard format (F1) of the nominal width b02.This is the turn of a mere impression page widths Part track avoidable, it can be a three pages printed in alternative format F2 side by side partial web B3 turned, and only after the turn before the funnel inlet to be cut longitudinally.

In a further development of the printing press, the funnel group is standard funnels 08 ; 09 an additional former 11 , z. B. additional funnel 11 , assigned, in particular sibling. This additional funnel 11 is preferably also formed transversely to the web running direction movable. In its "waiting position", ie, for example, in unused position when, for example, driven in standard production, is the additional funnel 11 completely out of alignment, which is dictated by the width of the printing cylinder. In operation, it may be spent towards the machine center and the adjacent standard hopper 09 connect directly. Should the Zusatzfalztrichter 11 are used only for production in alternative format F2, it has z. B. only one og reduced width b 'on. With this additional funnel 11 is it possible, such as in 11 shown as an example, in multi-lane operation turned or unswept partial webs also on this former and thereby produce a higher number of, longitudinally folded or cut in the fold, partial strands.

In 12 different versions for formers with variable effective width are shown, wherein under a) at least in the center of the machine directed portion of the funnel 08 ; 09 optionally attachable or removable lugs are provided. These are removed in the case of the collision and re-scheduled or unfolded for standard production. Under b), an embodiment is indicated, wherein at least in the area directed to an adjacent funnel area of the respective funnel 08 ; 09 Recesses are provided in the upper region such that they are ineinanderbewegbar with a corresponding region of the adjacent funnel in the manner of a toothing at least by a certain range. In a solution according to c), the former can 08 ; 09 ; 11 be so slightly offset in height to each other so that they do not interfere with each move.

As in 9 and 10 indicated, are also the standard funnels 08 ; 09 downstream train groups 12 designed to be movable transversely to the web running direction.

The aforementioned embodiments for movable formers, the width variability of the formers, the turning bar, the additional hopper and the movable train groups can individually but advantageously combined to several and complementary to each other in a printing press for use. In the 1 to 8th Exemplary web guides of such printing machines are set forth.

Show here 1 and 2 two web guides from the standard production with four printed pages of the standard format F1 having printing pages side by side, wherein in 1 the partial webs B1 and B1 in the straight line run (without turn) on the funnel structure 06 be guided. In 2 a sub-web B1 is turned on the flight of the other sub-web B2 and on a common former 08 guided.

In the 3 to 6 is produced in alternative production with five (n + 1) juxtaposed printed pages of the smaller / narrower format, wherein 3 all partial webs B3, B4, B5 straight (without turn) on the funnel construction 06 and side by side on the three formers 08 ; 09 ; 11 (narrower effective width!) Are performed. In 4 is a three-side width (or 3/5 of the nominal width b02) sub-web B7 over a "long" turning bar pair turned over and then again cut longitudinally on the funnel structure 06 (with the smaller effective widths). In 5 For example, a three-side-width partial web B8 is led straight ahead and cut again before the funnel construction, while a two-side-wide partial web B9 is used. In 6 a fifth section B11 is turned.

In 7 For example, as noted above, an exemplary example of standard production is shown with a somewhat narrower first format F1, while in 8th exemplarily the example 4 for alternative production (5 or n + 1 pages) for a somewhat narrower alternative product.
