1 and 2 show an exemplary top view of embodiments of a trained as a web-fed rotary printing press, especially a newspaper printing machine. The printing press has at least one printing unit 01 with several, in particular stacked, printing on, in which one of a reel changer 06 originating railway 02 , z. B. paper web, for example, is printed multi-colored on both sides. Form and transfer cylinder 03 ; 04 the, in particular as a printing tower with at least eight (eg on both sides in each case four) pressure points executed printing unit 01 have an effective bale length, which at least two, z. B. four (double-width) or six (three-width) juxtaposed printed images of stationary newspaper pages or at least two, z. B. four (double width) or six (three-width) juxtaposed printed images of horizontal printed pages, z. B. magazine pages, in tabloid format. When printing, the form cylinder 04 then on its lateral surface z. B. one or more printing forms with a total of four print images of corresponding printed pages in tabloid or newspaper format.

After printing passes through the web 02 a so-called superstructure 07 in which it by a longitudinal cutting device 08 in - preferably two-sided width - partial webs cut longitudinally, if necessary provided turning devices 09 z. T. laterally offset and brought to another flight, possibly provided by register facilities 11 the partial webs are aligned relative to one another in the longitudinal direction, and finally in a funnel structure 12 folded into strands longitudinally, and these strands then a cross cutter 13 , z. B. the cross-cutting device of a folder 14 be supplied. In the advantageous case of a newspaper printing press which can also be used for the printing of semi-commercial products, the printing press has at least one of the printing units in the web path 01 a dryer, not shown.

In 1 and 2 schematically two advantageous embodiments for the preparation of the above components are set forth: In the execution of 1 is the funnel construction 12 in the machinery aligned and in principle after leaving the printing units 01 by "straight-ahead" of the tracks 02 or partial railways reachable. turning devices 09 may be omitted here if necessary. However, in the case of a double or triple width machine with part webs to be turned, the turning device is 09 or the turning devices 09 at least one longitudinal cutting device 08 upstream. It can in the event that none of the partial webs must be turned, the slitter 08 or additionally an optional optional longitudinal cutting device 08 be arranged directly in front of the funnel inlet. In the execution after 2 is the funnel construction 12 with respect to its projected into the horizontal direction of curvature rotated by 90 ° for machine alignment and after leaving the printing units 01 by an angular web run over a turning bar of a turning device 09 reachable. For the case to be used partial webs is the turning device 09 or the turning devices 09 at least one longitudinal cutting device 08 upstream. In the event that a turning bar is provided with an effective length, which in projection on the incoming web at least the width of a maximum to be printed web, z. B. four or six juxtaposed printed pages in lying tabloid or standing newspaper format (broadsheet) corresponds, the said slitter can 08 or an additional, optional optional longitudinal cutting device 08 be arranged directly before the funnel inlet, so after turning.

The funnel construction 12 has at least one former 16 , but advantageously at least several formers 16 . 17 , z. B. a funnel group with several, in particular two or three juxtaposed formers 16 ; 17 on a same hopper level and / or two or three stackers arranged one above the other 16 . 17 in different levels. The term "at the same level" here means that the funnels of this funnel plane are located in the same machine plane and / or are at least cut by a same horizontal plane, in addition to the longitudinal cutting device 08 generated main section line are z. B. directly upstream of the formers or directly after the formers longitudinal slitting devices 19 provided, which cuts the partial webs in the alignment of the Falzrücken with a funnel center section along so-called. Nebenschnittlinien longitudinally. The superimposed by the corresponding folder other layers are then not folded on both sides, but are einseitenbreit loose on each other. The knives of the main cutting lines from the slitter 08 and the side cutting lines from the slitter 19 can structurally also as a common longitudinal cutting device arranged directly in front of the funnel inlet 08 . 19 be summed up.

Preferably, the printing units or the form cylinder 04 at least one of the printing units 01 "Double-sized" with so-called "double circumference" formed. Ie. the corresponding form cylinder 04 has a circumference, which two standing pressure sides, z. As newspaper pages, in broadsheet arrangement and / or four lying printed pages, z. B. magazine pages, in tabloid arrangement. In operation, the form cylinder 04 in the circumferential direction on its lateral surface one behind the other, the printed images of two stationary newspaper pages or four horizontal magazine pages. The two successively arranged newspaper pages or four magazine pages arranged one behind the other can, in one embodiment, extend on a common printing form extending substantially around the full circumference, but also advantageously on two printing forms arranged one behind the other in the circumferential direction 21 be arranged. In the latter case, when replacing a print page, the other pages do not need to be replaced. The printing forms 21 For example, each with their ends in z. B. over the entire effective ball length continuous - channels 22 held. Due to the double-sized version of the forme cylinder 04 can be twice as many printed pages per turn on the web to be printed 02 To Print.

3 provides only schematically (and for simplicity without the provided in the case of the offset printing unit transfer cylinder) a form cylinder 04 with printed images in a lying tabloid format (F1) as well as a printed with the corresponding printed image pattern web 02 A possibly alternative mode of operation with stationary print images in broadsheet format (F2) is exemplarily indicated dotted for the dimension of a printed page and transferred to the remaining printed pages.

If the same print images, that is to say the print images in the circumferential direction in each case two times, are arranged on the two halves of the circumference, the same print image or the two same print images is or are on the web twice in succession with a forme cylinder rotation 02 printable. The corresponding with the two halves of the circumference printing sections on the printed web 02 are in 3 by way of example with section A and B, or in the case of multiple-width paths 01 in additional distinction of the sub-paths defined by the main cutting lines 02.1 ; 02.2 denoted by A1 or A2 and B1 or B2. In so-called "double production", the printed image in section A (or A1 and A2) corresponds to that of section B (or B1 and B2) The same product is then in this operating mode with "double production" per machine revolution hung twice and behind the folder 12 interpretations.

In the advantageous mode of operation here, the printed pages of different printed images, that is to say the printed images in the circumferential direction, are in each case simply arranged on the two peripheral halves one behind the other. So are with a form cylinder revolution several -. B. two broadsheet pages or four taboo pages - different print images just in a row on the web 02 printable or printed. The corresponding with the two halves of the circumference printing sections on the printed web 02 ( 3 ) are printed with mutually different printed pages. In this mode of operation called "Collective Production", the printed image in section A (or A1 and A2) does not correspond to that of section B (or B1 and B2) .The two successive differently printed sections A; B; A1, B1; A2 ; B2 can be in this mode in the folder 12 "Collect", ie superimpose and summarize in a product.

The folder 12 is as a collectible operable folder 12 formed and has at least one as a collecting cylinder 23 operable transport cylinder 23 and a jaw cylinder 24 on. The cross cutter 13 can in Strangweg storm upstream of the transport cylinder 23 or as shown, as one with the transport cylinder 23 as an abutment cooperating cutting cylinder 26 , with z. B. two circumferentially spaced knives may be formed. The collection cylinder 23 has an odd number on the circumference, z. B. depending on the requirements of the format and / or the sections to be collected and / or the product strength to be achieved three, five or seven, holding elements 27 , z. As puncture needle groups or gripper, on, by each of which the leading end of the previously cut strand is received and held. Due to the odd number a strand section can be added, and after another round and the inclusion of a second strand section until the second pass of the nip with the jaw cylinder 24 be delivered as a product section P to the latter. The folder 12 further includes a first stapler 18 , in particular a ply stapler 18 , on, by means of which at the collecting cylinder 23 superimposed layers are connected by stitching together. Preferably, the ply stitcher acts 18 with the collecting cylinder 23 together and connects the layers to be connected to several, z. B. two, transversely to the transport direction spaced locations. The connection 20 , z. B. several, z. B. two stitches 20 is preferably carried out in the region of a line L explained in more detail below, which lies in the region of the first transverse fold to be produced in the connection.

At least one web path between at least one printing unit 01 and the folder 12 is a device for generating recesses 28 , z. B. a punching device 28 , in particular a rotary die 28 arranged. By means of these are recesses in the web path associated with this path 02 or partial track 02.1 ; 02.2 or in which the train 02 or partial railway 02.1 ; 02.2 this Bahnweges after passing through the former 16 ; 17 containing strands 31 ; 32 or strand bundles 31 ; 32 produced. In the Strangweg of this train 02 or partial railway 02.1 ; 02.2 after passing through the former 16 ; 17 containing strand bundle 31 32 may preferably at least one device for the connection of strand layers 29 , preferably a second stapling device 29 or according to product requirement if necessary, a Querleimeinrichtung (with correspondingly required temporary strand division and glue device), but in particular a strand binder 29 , be provided.

The punching device 28 is formed or at least operable such that punching with the corresponding pattern of recesses 33 only once per revolution of the forme cylinder 04 , ie only in one of the two of the double-sized form cylinder 04 printed sections A; B is effected ("skip-stiching") .Punching takes place in particular at one point along the web or partial web or the strand exactly between two successive printed images, in particular on a downstream in the folder 12 For the case of two printing plates in the circumferential direction, this line L is advantageously located in the circumferential direction through the forme cylinder 04 applied print image between the two print images of a same of the two printing plates and in the case of only one four tabloid pages in a row having printing form between the first and the second or between the third and the fourth printed page. As a result, only in one of the two consecutive sections A; B or A1; B1; A2; B2 a punching with the recess 33 , The other section B; A or B1; A1; B2; A2 remains unpunched. Preferably, i. V. m. the punching device 28 provided a not specifically shown suction.

The punching device 28 can, as in 4 shown schematically, on the web path in front of the downstream former 16 . 17 or in the strand path after the former 16 ; 17 be arranged. In the first case, the punching device 28 z. B. in such a way - one or more parts - designed so that by means of this in the on the former 16 ; 17 incoming double-sided partial web 02.1 ; 02.2 or in the possibly still uncut corresponding web strip of a web 02 symmetrical to the center of the partial web or of the strip per one-side-wide Teilbahn- or strip half one or more recesses 33 can be introduced. Thus come the recesses 33 the one-side partial web or strip halves after passing through the downstream former 16 . 17 to lie on each other. In the example shown, each one-side partial web or strip half are two transversely to the web running direction spaced recesses 33 intended.

In one embodiment, in which no difficulties with respect to the requirement for symmetry can occur, the stamping device is 28 in Strangweg after the former 16 ; 17 arranged and provides the strand concerned 31 ; 32 , In particular in the region of the above-mentioned point or line L, with one or more recesses spaced transversely to the direction of travel 33 ,

The punched out 33 have transverse to the web running direction z. B. a length of at least 5 mm, in particular between 7 and 30 mm, and a width of z. B. at least 2 mm, on.

The punching device 28 In a variant, it can also be designed as a perforating device for section-wise transverse perforation, in particular in the region of the line L. The "recesses" 33 are in this variant as short perforated line-like sections with z. B. a length of the perforation transverse to the web direction of at least 5 mm, in particular hissing 7 and 30 mm, is formed. However, it can by the punching device 28 a framed by a perforation surface according to the above dimensioning of the punched 33 be provided.

Should the or more layers of the stamped section A1 of the strand 31 ; 32 downstream section produced by transverse cutting A1 ', z. B.

Strand section A1 ', be connected to each other, so goes through this strand 31 . 32 the device provided for this case in the strand path for the connection of strand layers 29 , in particular the second stapling device 29 , The connection 34 is preferably carried out by several, for. B. two, transversely to the direction of each other spaced stitches 34 or glue spots (or a transverse glue trace). The connection preferably takes place at the same point along the path or partial path or strand as the punching, in particular along the line L. In the case of punching, downstream of the former 16 . 17 can be connected first and then punched or vice versa - the device then being placed in the appropriate order in the strand path.

After passing through the punching device 28 and if necessary, the Stranghefters 29 the strand is running 31 in the folder 14 one. In the advantageous case of two formers 16 ; 17 and two resulting strings 31 ; 32 , these are in front of or at the entrance of the folder 14 to a strand 38 , z. B. total strand 38 , summarized and together in the folder 14 guided. Here, the strand sections of the two strands come to rest on the collecting cylinder. As in 6 shown schematically come z. B. in the first rotation, the two sections A1 'and A2', and on the second rotation, the sections B1 'and B2' lie above. The inner section A1 'has the punches 33 and if necessary stitches 34 on. The place of punching 33 corresponds with the intended places for the stitches 20 of the file stapler 18 now in such a way that when stapling all layers without punches by means of the layer stapler 18 connected to the recesses 33 However, due to the present at the place of stapling recess (s) 33 stay disconnected.

Through the recesses 33 i. V. m. the ply stapler 18 Thus, it is possible in the resulting product two partial product sections, so-called. Sections 39 ; 41 or "books" 39 ; 41 to produce with varying numbers of layers, with at least one of the two sections 39 . 41 (the one with the layers without recesses 33 ) through the ply stapler 18 connected to each other. When using the strand stapler 29 are the recesses 33 having layers also joined together. Without Strangheftung these layers are loose and thus individually removable.

In 6 and 7a are the layers with the product sections A1 '; A2 '; B1 '; B2 'in each case for the sake of overview in one layer. Depending on the number of rollers on the former 16 ; 17 accumulating tracks 02 and an optionally preceding turning of one- or two-page-wide partial webs 02.1 ; 02.2 or a strand division or mixture described below, however, these can also be multi-layered. In the example of the 4 with the two tracks 02 or the four partial webs 02.1 ; 02.2 have the product sections A1 '; A2 '; B1 '; B2 'two layers each. 7a schematically shows the four superimposed product sections A1 '; A2 '; B1 '; B2 'in single-layer representation while 7 schematically the two resulting sections 39 ; 41 in a section through the line L shows.

In 8th are in one-layer representation of the two sections which lie behind each other after the transverse folding 39 ; 41 shown. Here it can be seen that two printed in collective mode of the four-page and double-sized printing units webs 02 a product with a total of 48 pages in two sections 39 ; 41 different page numbers is producible, with the outer, by the ply stapler 18 stapled section 39 this 48 pages, and the in nere, if necessary, stapled or not stapled by the stitch stapler 41 only 16 pages. In this version, the two tracks 02 unfocused and without strand division in the "straight running" run through the printing press.

In an in 4 dashed line indicated training is at least one of the formers 16 ; 17 coming strands 31 ; 32 divisible trained. Ie. they are not shown, z. B. a transfer roller below the folder 16 ; 17 provided on which a strand 31 ; 32 divisible in the way that a substring 36 ; 37 of a strand 31 ; 32 branchable and the other strand 32 ; 31 can be fed. The remaining remaining strand 31 '; 32 ' then runs z. B. continue as described.

Thus, for example, in one of the above-mentioned "straight-ahead operation" first variant, a sub-string 36 of the strand 32 taken and together with the strand 31 through the punching device 28 and possibly the stapling device are guided. The inside section 41 is thereby increased in its position or page number (see 9 ). In 9 has the inner section 41 when processing two webs 02 a "double layer" more (ie 24 pages), ie eight pages more, and the outer section 39 eight pages less (ie 40 pages).

Conversely, in a second variant, a part of the strand 31 as a substring 37 decoupled and with the strand 32 together without punching and without stapling to the folder 14 be guided ( 10 ). The resulting product then has z. B. when processing two webs 02 an inner section 41 with a "double layer" less, ie eight pages less (ie 8 pages), and the outer section 39 eight pages more than in the above-mentioned straight-ahead operation (ie 56 pages).

It is also possible to transfer a number of layers differing from the above example from one to the other strand. The above examples are also to be transferred to versions in which instead of a strand division and mixture before the former 16 ; 17 a turning of one or more partial webs 02.1 ; 02.2 takes place and thereby the number of layers is varied.

Basically, the o. G punching and layering is also on a printing press with only one former 16 applicable. A product which can be produced in this case then has, for example, an inner, non-stitched section 41 with recesses in the area of the fold back and an outer section stitched in the area of the fold back 39 on.

Advantageous with regard to variable and / or different page numbers in the sections 39 ; 41 However, is the execution in a printing machine with at least two formers 16 ; 17 , which are arranged side by side or one above the other.

11 shows a product with two sections 39 ; 41 the same number of layers, which can be produced optionally with the printing press.
