DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0009]
An object of the present invention is to provide an offset printing unit of a printing press for newspaper printing and a web rotary printing press.
[Means for Solving the Problems]
[0010]
This object is achieved according to the invention by the features of claim 1, 4 or 45.
[0011]
An advantage that can be realized by the present invention is that, in particular, a low-cost, high-productivity web rotary printing press design form is possible in order to reliably produce various product formats.
[0012]
This is possible, for example, with six three-sided machines, for example by two three-sided blankets arranged side by side. Various types of webs, for example, each of the material webs, run in the center with respect to the rubber cylinder so that the butt of both blankets at the center double plane is a longitudinally folded area of the non-printing area. Will be located.
[0013]
It is particularly preferred that the device or devices can be adjusted to different web widths by means of guide members and / or processing members cooperating with the web. This is, for example, a former roll arranged side by side with a crimping roll of a retracting device, a catching roller of a catching device, a cutter of a longitudinal cutting device, a crimping roll of a tension group and / or a folding structure. The web is preferably passed through the machine symmetrically with respect to the central axis of the printing press, i.e. at the center with respect to the cylinder width. In one advantageous development, if the guide member and / or the treatment member are odd, the middle member is arranged in the plane of symmetry described above. This member may be fixedly arranged transversely to the conveying direction, whereas the outer guide member and / or processing member is movable transversely to the conveying direction, whereby the web width It is preferable that it is manufactured so that it can be adjusted according to.
[0014]
In addition to this, the triple width embodiment of the printing press has the advantage that the certainty of production is significantly increased compared to the double width printing press if the planned thickness of the product to be achieved is the same. On the other hand, the production capacity of the printing machine or each printing unit can be improved by 50% while maintaining the number of printing units. Reduces splicing equipment (investment), splicing frequency (reliability of production), and set-up time (cycle time) when pulling in webs compared to double-width printers for the same product thickness .
[0015]
In an advantageous embodiment, the printing unit is manufactured as a nine-cylinder satellite type printing unit, which on the one hand gives a high color registration accuracy and on the other hand a design with less vibration. The configuration as a satellite type printing unit is that when there is a demand to produce printed matter of various web widths in the BB type printing unit, there is a direct contact zone where there is no paper web for at least one web width. It is also preferable for the reason. As is well known, this leads to a transport behavior where the change is too great, which can result in partly significant registration errors and wrinkles.
[0016]
Vibrations are also avoided by the advantageous arrangement of the lining on the torso, construction form and mounting method. On the other hand, the opening of the outer cylinder surface is minimized in the circumferential direction. Further, at least in the rubber cylinder, at least one section length is arranged with the openings alternately displaced in the circumferential direction so that the closed outer cylinder surface always cooperates with the plate cylinder or the satellite cylinder. It may be.
[0017]
It is particularly preferable to cover the rubber cylinder width symmetrically only by the two three-print surface widths. In this way, printing can be performed with various web widths without changing the blanket in advance, unlike the three blankets having two printing surface widths that have been conventionally used.
[0018]
The drive of one (or more) satellite cylinders mechanically independent from each set of cylinders provides advantages, particularly in the sense of allowing variable operating conditions. For example, setup operations such as flying-type plate change and cleaning can be performed during production. Conversely, the web can be retracted while another cylinder or set of cylinders is stopped or while the setup program is in progress. It is also preferable to operate the satellite cylinder at a different surface speed than the other cylinders if there is a blanket with the characteristics of active or passive transport.
[0019]
In an advantageous embodiment, the superstructure of the printing press has at least one longitudinal cutting device with at least five cutters spaced from each other transverse to the direction of paper travel.
[0020]

The plate cylinder 16 and the rubber cylinder 17 have, in a particularly advantageous embodiment, a covering with a cylinder tension 19; 21 as shown in FIG. In addition to this, FIG. 4 shows a particularly advantageous arrangement of the gaps 27; 36; The plate cylinder 16 has two gaps 27 or gap openings 28 (openings 28) spaced circumferentially from each other by 180 °, each continuous over the effective length of the plate cylinder 16 and rubber. In the cylinder 17 there are two gaps 36; 37 or gap openings 38; 39 (openings 38; 39), each circumferentially offset by 180 °, which are continuous over half the effective length. The gaps 27; 36; 37 are shown only in FIG. 4 as slits for inserting the end of the waist, but as will be explained in detail later, to accommodate corresponding clamping devices and / or clamping devices. The inside may be open.
[0037]
FIG. 4 schematically shows a printing unit 13 having a plate cylinder and a rubber cylinder 16; 17 for printing a variable web width, together with a folding structure 11 which will be described in detail later, and with two web widths. It is shown in the figure. In the first operation mode, it is possible to print the web 03.1 having the first width b1 in order to print with the first printing surface format F1, and in the second operation mode, it is smaller than this. A web 03.2 having a second width b2 can be printed for printing with the second printing surface format F2, and the rubber cylinder 17 has at least six newspapers of the larger printing surface format F1. The width of the surface is in the axial direction, and two blankets are arranged side by side along the circumference of the circumference, and these blankets are at least the smaller format F2 (for example, the printing surface format F2). ), But preferably the larger format F1 (for example, printing surface format F1), each having three newspaper printing widths in the axial direction.
[0038]
The number of newspaper printing pages when viewed in the axial direction is, for example, the same in the first operation mode (newspaper printing, F1) and the second operation mode (newspaper printing, F2). This number of faces is preferably six faces of the corresponding format F1; F2.
[0039]
The larger width b1 is suitable for printing six newspaper pages arranged side by side in the first format F1, for example 1,800 to 2,500, preferably 1,900. To 2,400 mm, in particular 1,900 to 2,200 mm. The smaller width b2 is suitable for printing six newspaper pages arranged side by side in the second format F2, for example, 1,750 to 2,100, preferably 1,750. To 2,050 mm, preferably 1,850 to 1,950 mm, where b1> b2. The possible width for newspaper printing is not limited to the two listed above, but can be applied to any arbitrary width or format between them. That is, in principle, any web 03 with a wide variety of widths (or corresponding newspaper formats), for example, between 1,750 mm and 2,400 mm, at least between 1,850 and 2,200 mm. Can be changed.
[0040]
3 and 4 also illustrate the virtual printing machine central axis M. FIG. Both the upholstery 21 are arranged symmetrically with respect to the printing machine central axis M. The webs 03.1; 03.2 pass through the printing unit 13 symmetrically with respect to the printing machine central axis M irrespective of the widths b1; b2.
[0041]
In at least one of the operation modes, the plate cylinder 16 of the printing unit 13 supports, for example, a printing plate 19 ″ that extends over at least three newspaper page widths of the current format F1; F2 as viewed in the axial direction. Then, for example, a printing image of three newspaper pages or a printing image corresponding to three newspaper pages as a whole is given to the printing plate side by side, and is particularly exposed. Of the three formers 41; 42; 43 arranged side by side, the former front end of the former former is also located on the printing machine central axis M (see below).
[0042]
FIG. 5 schematically shows the situation for the wide web 03.1 (FIG. 5a) and the situation for the narrow web 03.2 (FIG. 5b), the main cutting lines S1 and S2 being Both different product widths (web widths) are shown together. The “main cutting line” here means a longitudinal cut that hits the web 03 in a straight line between two adjacent formers 41; 42; 43, whereby the generated partial web is It becomes possible for the first time to guide through the adjacent formers 41; 42; 43. At this time (in S1.1; S2.1; S1.2; S2.2), the subscripts “1” and “2” are respectively different formats of the product when viewed transversely to the transport direction. F1 represents the first position of the main cutting line S1; S2 and the second position different from the first position, corresponding to the width b1; b2 of F1; F2 to the web 03.1; 03.2. . The longitudinal cut along the main cutting lines S1 and S2 is made before entering the former by the longitudinal cutting device 06 mentioned in the frame of FIG. 1 or by a comparable longitudinal cutting device not shown in FIG. May be manufactured. A particularly advantageous embodiment of the longitudinal cutting device (06; 65) suitable for this will be described later.
[0043]
FIGS. 5 to 10 are symmetrical planes of the respective formers 41; 42; 43, and if they are configured accordingly, the front ends of the formers are located. Here, reference numerals F41; F42; F43 are given. The folding plane is also illustrated. Here, the spacing A1 between the folding planes F41 and F42 and the spacing A2 between the folding planes F42 and F43 depends on the width b1; b2 of the web 03.1; 03.2 and / or the current printing. It can be seen that it varies depending on the surface format F1; F2 and / or depending on the type (symmetric / asymmetric) of applying the printed image. Such varying intervals A1; A2 are preferably realized by the movement of the outer former 41; 43, at which time the central former 42 remains stationary. The minor cutting lines S4; S5 (not shown in FIGS. 5 to 12) are, for example, in addition to the main cutting lines S1; S2 listed above, in addition to the folding plane F41, the folding plane F42 and / or the folding. It may be provided on the plane F43, and in the case of sub-cutting, a vertically folded product is not produced, but a multi-layered product is formed that is cut open at the back and positioned gently up and down (from FIG. 13). (See the tabloid product of FIG. 16 and the pouch-folded special format of FIGS. 17 and 18).
[0044]
With reference to FIGS. 6 to 10, the advantageous covering and configuration of the printing machine 19 cylinder 19; 21 will be described, in particular for the wide and narrow webs 03.1; 03.2. . However, the illustrated waistline 19; 21 is not a plan view, but corresponds to a completely unfolded body 16;
[0045]
In all subsequent explanations relating to FIGS. 6 to 10, the rubber cylinder 17 is equipped with two cylinders 21 having a larger three-print surface width so as to be aligned in the axial direction. Both of these linings 21 each extend around the entire circumference in one advantageous embodiment, with their respective ends (abutment to the gap openings 38; 39) in a straight line. They may be arranged side by side or offset in the circumferential direction by 180 ° (see above). In another embodiment, two waistboards 21 may be arranged one after the other in the circumferential direction, and in that case, both of the waistbands 21 having the three printing surface widths arranged side by side. The ends of the are aligned with each other. In any case, the two cylinders 21 arranged side by side in the axial direction extend at least over the length of the rubber cylinder 17 required to print the wide web 03.1 when combined. It is preferable.
[0046]
In FIGS. 6 and 7, an advantageous variant for covering the rubber cylinder 17 is shown in broken lines (that is to say two cylinders 21 with three printing surface widths each covering the entire circumference). 8, 9, and 10 show the embodiment in the axial direction of the three-plane width, but the embodiment in the circumferential direction is undecided, and among the examples described above It may be one of
[0047]
FIG. 6 shows the covering state of the plate cylinder 16 by the printing plates 19; 19 ′ in an operation mode or operation mode having a print image of the larger printing surface format F1. The web width corresponds to the wider width b1. In this case, all (12 in this example) printing plates 19 manufactured as the individual printing plates 19 may be arranged. However, a combination of the individual printing plate 19 and the panoramic printing plate 19 ′ (shown in the lower right of FIG. 6 as an example) may be placed on the upper side. The latter has a width of a plurality of (for example, two or three) individual printing plates 19 and contains a printed image (panoramic printing surface) with multiple printing surface widths, or the first (larger one) The printing surface format F1 includes a plurality of printed images each having one surface width or multiple surface widths. Here, a panoramic printing plate 19 ′ (19 ″) is distinguished from a panorama printing image or a panoramic printing surface. In this sense, the panoramic printing plate 19 ′ (19 ″) is an individual printing image or panoramic printing. You can have an image. The intervals A1 and A2 in FIG. 6 correspond to the width b19 that is twice that of the individual printing plate 19, or correspond to the printing surface width bF1 that is twice that of the larger format F1, or the larger one. This corresponds to the panoramic plate 19 ′ of the format F1 or the width b19 ′ of the panorama print image. The printing plates 19; 19 ′; 19 ″ are preferably configured as lithographic printing plates for offset printing.
[0048]
FIG. 7 shows, unlike FIG. 6, the covering state of the plate cylinder 16 by the printing plate 19 ″ in an operation mode or operation mode having a printed image of the smaller printing surface format F2. This corresponds to the narrower width b2.In this case, in an advantageous embodiment, two panoramic plates 19 "are arranged symmetrically with respect to the printing machine central axis M, respectively. Each of the widths of a plurality of (for example, two, especially three) individual printing plates (not shown) that is theoretically necessary for the smaller format F2 is provided. As shown in FIG. ) A plurality of (three in this example) single print surface width print images of the print surface format F2 are respectively included, or a print image having a multi print surface width and a print image having a single print surface width as shown in FIG. Including. In FIG. 7, the plate cylinder 16 contains four printing plates 19 ″ of this kind, which include three printed images of the smaller printing surface type F2 side by side (two are arranged side by side on the circumference, With a double circumference (ie, two newspaper pages on the circumference), and the plate cylinder 16 with a single circumference is of this type 2 Only one printing plate 19 "will be provided side by side. In FIG. 8, the printing plate 19 ″ has a print image having a multi-print surface width and a print image having a single print surface width. Further, a mixed-type modification is also possible, but this is illustrated here. The intervals A1 and A2 in Fig. 7 and Fig. 8 respectively correspond to a double width of a potential individual surface printing plate (not shown) or a double printing surface width bF2 of the smaller format F2. .
[0049]
The printing plate 19 ″ having the smaller printing surface format F2 has not only three printing surface widths, but also extends to the end of the effective outer cylinder surface of the plate cylinder 16. Preferably, both plates 19 "arranged side by side have a width corresponding to the maximum width b1 of the wider web 03.1 or the larger width b1 when the two are combined. Yes. Thereby, a more uniform conveying behavior is possible regardless of the currently used web width over the effective length L16 of the plate cylinder 16 and / or the narrower web 03.2 is used. The risk of drying the corresponding lining 21 in the edge area when doing so is reduced. In that case, the plate 19 "contains a printed image asymmetrically with respect to its width and is exposed, for example, asymmetrically during manufacture. The non-printed edge area is 50 to 100 mm.
[0050]
FIGS. 9 and 10 show the coating of the plate cylinder 16 with a three printing surface width printing plate 19 ″ comprising an asymmetric printing image. Two printing images on the printing plate 19 ″ (for example, Formats or printing surface formats F4 and F5) do not have an integer ratio of width here. Cutting line S1. x; S2. x (SIC) is not symmetric with respect to the printing press center axis M, for example. The intervals A1 and A2 are different from each other, for example. In at least one of the three formers 41 to 43 (42 and 43 in this example), the folding planes F41; F42; F43 (F42; F43 in this example) are attached to the partial webs 03a; 03b; 03c (books) In the example, it does not coincide with the centers of 03b and 03c), so that the finished partial running paper folded in the vertical direction has unequal side lengths.

Before the description of FIGS. 13 and 14, the fourth former 44 (as the additional former 44) in FIG. 12 is, for example, the former in the above-described form of the former. Can have a larger maximum width than 41 to 43, ie clearly more than one sixth (b1 / 6) of the width b1 of the wider (or widest) web 03.1 The largest available side length can correspond to at least 120% of one sixth of the width b1 of the larger, especially wider web 03.1. Thereby, it is possible to selectively perform production (format F3) as shown in FIGS. 13 and 14 selectively for newspaper production (format F1; F2).
[0055]
In FIG. 13, the plate cylinder 16 (especially 6 newspaper widths) is similarly equipped with only two panoramic plates 19 ″ in the axial direction, but these panoramic plates are printed with tabloid F3 print images (ie The incoming web 03.3 has a further width b3 which is different from the first and second widths b1; b2 here. In the printed image, the product length after completion (after lateral folding) is located in the axial direction of the plate cylinder 16 and corresponds to a quarter (b3 / 4) of the width b3 of the web 03.3. (Refer to FIG. 14) The product width is the circumference U of the plate cylinder after the lateral folding (not shown) is completed. _FZ Of substantially one quarter (U _FZ / 4). The width b3 is, for example, narrower than both other widths b1; b2, for example, 1,600 to 1,800 mm, preferably between 1,700 mm to 1,750 mm. Here, the printed web 03.3 is cut at its longitudinal center along a tabloid main cutting line S3 (advantageously coincident with the printing machine central axis M), both of the partial webs 03a; 03b being turned respectively. Through the bar 46, the direction is changed by 90 ° from the previous conveying direction toward the long side of the printing press, guided so as to be out of alignment with the three formers 41 to 43, and subsequently, Turn through the former 44 in a suitable orientation transversely to the printing machine central axis M, or with a further turning bar 46 (as shown) and turn again by 90 °.

As shown by a double arrow in FIG. 30, when three turning bars 69 that are movable to change the direction are provided, the partial webs 03a; 03b; 03c generated after the longitudinal cutting are replaced with three stationary formers 71; The position of the turning bar 69 can be found according to the widths b1; b2; b3 of the webs 03.1; 03.2; For example, using a former structure 11 with stationary formers 71 to 73, each of which has a fixed width corresponding to the width of the partial webs 03a; 03b; 03c resulting from the widest web 03.1. it can. In FIG. 30a, a partial web width turning bar 69 is provided for this purpose, and in FIG. 30b, a turning bar 69 is provided that is three times as wide (ie, at least six newspaper print widths of the larger format F1). ing. FIG. 31 includes a plurality of (two in this example) printing towers 01 or 02, each of which is a common format described in FIG. 30a or 30b but only schematically illustrated in FIG. The arrangement of the two printing press sections that are produced via the turning device 07 towards the structure 11 is schematically shown.
[0098]
FIG. 32 shows the folding structure 11 in a cross-sectional view. In this case, as shown, it may be slightly offset in the vertical direction (not shown) or fabricated with an additional piece 47 (shown only for the lower group), substantially the same former. Two groups of 41; 42; 43 may be arranged one above the other. Immediately between each former group, at least one former introduction roller 76 or tension roller 76 driven by a motor 74 is provided.
[0099]
The folding device 12 of the printing press is, in an advantageous embodiment, made in 7 zones for all the previous examples.
[0100]
The circumference of the transport cylinder 77 corresponds to more than five section lengths, in particular seven section lengths or seven signatures (“7 section transport cylinder 77”). In the conveyance cylinder 77, seven holding devices provided on the circumferential surface of the conveyance cylinder 77 at equal intervals in the circumferential direction, for example, puncture strips with puncture needles that can be fed are arranged. (Puncture type folding device). The holding device may be manufactured as a gripper (gripper type folding device). Further, each of the conveyance cylinders is slightly (for example, 0.3 to 3 cm) as viewed in the rotation direction with respect to the position of the clamp point (gripper type folding device) or against the puncture penetration part (puncture type folding device). Seven cutting strips, which are preferably arranged at intervals on 77 outer cylinder surfaces, are arranged. The circumference of the gripper cylinder 78 also preferably corresponds to more than five section lengths, in particular seven section lengths or seven signatures.
[0101]
Further, seven folding blades are attached to the conveying cylinder 77, and these folding blades are reached each time when the gap between the conveying cylinder 77 and the holding cylinder 78 is reached (depending on whether the stacking operation or the standard operation). Or the signatures that have been fed out and conveyed by the conveying cylinder 77 are handed over to the holding cylinder 78 for folding. For this purpose, the holding cylinder 78 has, for example, the same number of holding parts (not shown) as the number of folding blades and / or the holding device of the conveying cylinder 77, which are equally spaced in the circumferential direction. In this example, there are especially seven. The folded product is transferred from the gripper cylinder 78 to the impeller 79, and is discharged from there to a paper discharge device 81, for example, a conveyor belt 81.
[0102]
The saw blade cylinder 82, which cooperates with the conveying cylinder 77 as a transverse cutting device, is manufactured to be provided with two cutters on the circumference that are twice as large, ie spaced apart by one section length. Alternatively, it may be made to have four cutters on the circumference that are four times as large, ie spaced apart from each other by one section length.
[0103]
In particular, the asymmetrically exposed panoramic plate concept, created with at least one of a plurality of laterally movable formers 41; 42; 43, is a six-sided machine (lined with six printed images). In addition, the present invention can be applied to other machines, in particular, a four-sided newspaper printer (four printed images are arranged side by side). In that case, for example, n = 3 printed images for a six-sided machine and n = 2 printed images for a four-sided machine are aligned side by side in the axial direction, particularly on the printing plate 19 ″. 33a and 33b, an example of which is shown in Fig. 33a and 33b, in which the plate cylinder 16 is covered with the larger format F1 printed image, in this case four printings. The images are arranged only on the eight individual printing plates 19, or only on the four panoramic printing plates 19 '(each two are arranged side by side), or a combination thereof. (Combined as an example in Fig. 33) The plate 19; 19 'preferably covers the entire effective length L16 or the width b1 of the larger web 03.1 to be printed. It is preferable to cover the printing unit 13. When it is manufactured with 1x instead of 2x circumference (2 newspaper pages in the circumferential direction), the above-mentioned is achieved by 4 individual printing plates 19 or 2 panoramic printing plates 19 'or a mixture thereof. The same applies.
[0104]
In another mode of operation in which a narrow web 03.2 is used, the plate cylinder 16 has a smaller format F2 printed image. At this time, the printing plate 19 ″ is also produced as a panoramic printing plate 19 ″, except that it is produced as a panoramic printing plate having two printing faces of the smaller format F2, but still has a wide web 03.1. It preferably extends substantially over the entire region of possible printing length, i.e. it has the same width as the larger format F1 panoramic plate 19 '. At this time, the plate 19 ″ is exposed, for example, asymmetrically as described above. Similarly to the configuration described above with three formers, the former structure is also preferred here, the folding plane F42; The interval A1 of F43 can be changed in the manner described above.
[0105]
As shown in FIG. 33, as an example, two blankets 21 are arranged side by side on the rubber cylinder 17, and these blankets are newspaper type F1; Each of F1 has a width of two printing surfaces. Each of these blankets may extend over the entire circumference and may be arranged on the rubber cylinder so that the respective ends are also aligned with each other, or alternating by 180 °.
[0106]
The following description of the printing press shown in FIG. 34 is not only advantageously applicable when viewed by itself, but is particularly advantageous when combined with one or more of the components described above. For example, a three newspaper width printing machine 21 and / or a three newspaper width printing plate 19 and / or a format variable and / or one or more Guide member and / or processing member 41; 42; 43; 52; 62; 66 as described above, and / or satellite structure, and / or configuration of gap opening 28; 38; 39, and / or gap Clarified that it can be advantageously applied in combination with the width of the opening and / or the special configuration of the formers 41; 42; 43; 44 and / or other components not mentioned above. Keep it. The same applies to FIGS. 35 and 36.
[0107]
FIG. 34 shows a printing press according to a triple-width construction mode for printing six newspaper pages arranged side by side (for example, two planes each having three side-by-side formers). Each fold structure 11 is provided with a printing tower 01; 01a, which is equipped with a stacked printing device, in particular a satellite type printing device, on both sides. A printing press area having substantially the same type of equipment has, for example, two printing towers 01; 01a on both sides of the folding structure 11, and in one advantageous development, at least one of these printing towers 01 For example, in addition to the eight printing locations of the satellite-type printing device 02, two additional printing locations are attached, for example, in the form of a six-cylinder printing device 83 or in the form of a three-cylinder printing device 83. ing. These two additional printing locations may be preferred in combination with one or more of the above-described components, in some cases, even in the printing tower 01 of the printing press separated from the special printing press shown in FIG. is there. In the printing tower 01a thus expanded, two webs 03 can be printed with four colors on one side and one color on the other side, respectively, or one web 03 can be printed with four colors on both sides. And the other web 03 can be printed in one color on both sides. This printing machine is different from the Paltail model (see FIGS. 35 and 36), and has a multi-layer structure in the sense that the printing tower or the lower printing device 02 and the splicing device 05 are not arranged on the same equipment plane. It is made with. Here, the printing tower 01 is arranged on a plane T that is above the plane G that supports the splicing device 05. The former is, for example, arranged on a so-called “table”, in particular, on a concrete table.
[0108]
The printing machine of FIG. 34 has three printing machine areas of the kind described above in this example. ^* As shown, the web 03 can be transferred from the printing tower 01 located in the adjacent printing press area, but from the printing tower located before the next folding structure 11. For example, five paper splicing devices 05 are attached to each of such areas consisting of the four printing towers 01; 01a and the folding structure 11. Depending on the requirements imposed on the desired production, a turning tower with three, four or five turning devices 07 (turning decks) may be provided. Each folding structure 11 is followed by a folding device 12 (here, F1, F2, F3). In addition to this, FIG. 34 also lists options relating to advantageous production methods and products. This notation method will be described by taking up the production form of the gray background color for the web guide format listed in the third line.
[0109]
In the configuration shown in the third row, two products (2x) each having 84 pages (S) are produced from seven webs (B) by two folding devices (here, F1 and F3). In this example, this is due to the broad sheet configuration (that is, the longitudinally long newspaper surface of the plate cylinder 16) and the double production, that is, the operation that does not perform the stacking operation (the stacking operation or abbreviated as unges. Done. In this case, for example, two identical printing plates 19; 19 ′; 19 ″ are placed on the plate cylinder 16 which is twice as large as each other, so that doubles per unit time per running paper. The production volume can be produced, or two different products can be produced on the running paper alternately, and the two product flows can be switched accordingly. In the apparatus 12 (F1), for example, four webs initially printed by 4/4 printing are guided from the right side, and two webs of 1/4 and 4/1 printed by the left outer printing tower, And a 4/4 web printed in an adjacent printing tower is guided in. The product has 84 pages, 72 of which are printed in 4 colors (and the rest are 1 color) (84/72). For products made with other folding devices (F3), In the example, the same applies as above: the other nine rows of the table can be read in the same way, for example, in the sixth row, two folding devices (F1 and F3) each with six webs (B.) To 72 pages (S.) and a product having 60 surfaces of four colors is manufactured, and a product of 24 pages is manufactured by one folding device (here, F2).
[0110]
In one advantageous embodiment, at least one offset printing unit 13 of the printing device 02 of the printing tower 11 (for example, all the printing devices 02; 83 of the printing tower, but preferably all of the entire printing area) Printing device 02; 83, but in particular all printing devices 02; 83) of the printing press are equipped with a three-sided printing plate 19 "and / or a three-sided width cylinder 21 in the embodiment described above. It is configured so that it can be equipped.
[0111]
The folding structure 11 has, for example, at least one former plane, but advantageously two former planes arranged one above the other with three formers 41 to 43 arranged side by side. (For example, shown in FIGS. 4 to 16). One or more of these folding structures 11 additionally have lateral additional formers 44 (or possibly additional former planes) as illustrated in FIGS. Is preferred.
[0112]
FIG. 35 shows a Paltail-type printing machine, that is, the splicing device 05 and the printing tower 01; 01a are arranged on substantially the same plane, for example, in the Paltail plane E. This provides an advantage in terms of construction costs (no substructure, or the required height of the building 86 containing the printing tower 01; 01a, for example, the machine hall 86 is reduced). In that case, in the area outside the printing tower 01; 01a and / or the folding structure 11, the building 86 may be constructed significantly lower (shown in FIG. 35).
[0113]
As can be seen in the plan view (lower partial view), in the illustrated folding structure 11, an additional former 44 may be arranged on the side of a group of three formers. For example, this may be true for one or both of the former planes illustrated by the solid lines if both former planes have the same formrs 41; 42; 43 side by side. The additional former may have the same width as the other three formers, but may have a width wider than this as described with reference to FIG. Here, seven product running papers (for example, so-called “books”) can be run through a total of seven formers (2 × 3 plus additional formers). Optionally, a wider product can be run on the additional former. However, in an embodiment that does not use side-by-side additional formers 44, both former planes are arranged in the manner shown in FIG. 16 (three formers on one plane and two wider formers on the other plane). ) It may be manufactured. As shown in FIG. 32, two “standard” former planes in which three formers are arranged side by side are provided, and in addition to this, two planes located above (indicated here by broken lines) An embodiment may be optional in which two additional formers 44 are arranged above in the form of both upper formers 44 in FIG.
[0114]
One or more of the printing towers 01 may have an additional printing device 83, as indicated here by the reference numeral 01a.
[0115]
In the embodiment of the printing press shown in FIG. 36, the web feeding from the splicing device 05 is performed from the long side of the machine, that is, at an angle of 90 ° with respect to the printing press center plane M. Here again, the printing press is preferably made in partail form, ie the splicing device 05 and the printing tower 01; 01a are arranged in substantially the same plane. One or more splicing devices 05 are installed alongside the machine, and the rotation axis of the material roll or web extends substantially parallel to the central axis M of the printing press. After the web has been unwound sideways with respect to the machine, it is loaded into the redirecting member 84 at a height that is aligned with the machine, for example loaded into a guide member 84 in the form of a turning bar 84, so that the web After that, the direction of movement is located in the center plane M of the printing press. The guide member 84 has a length corresponding to at least its maximum width as seen in the projected view of the incoming web. The guide member is preferably inclined by 45 ° with respect to the direction of travel of the incoming web and with respect to the machine center plane M. In this example, the guide member has a length corresponding to the newspaper surface on which at least six projection views of the incoming web are located side by side. When the splicing device 05 is offset by 90 °, the available length of the turning bar 84 corresponds to at least 1.4 times the web width that can be processed to the maximum on the printing press, ie In the example, it corresponds to at least 1.4 times that of a web having a width of six newspaper pages, or in this example, corresponds to at least 8.5 newspaper pages. Two turning bars may be provided between the two printing towers 01 so as to cross each other, so that these turning bars not only change direction in one direction but also in the other direction. It also enables conversion. In that case, both intersecting turning bars 84 are selectively fed with this web by one splicing device 05 or, as shown, two splicing devices 05 located on the same straight line. Can be supplied at the same time.
[0116]
From the point of view of reliable web guidance, a retraction device for adjusting the web path may optionally be arranged in front of the turning bar 84, but advantageously the turning bar 84 and the entrance to the printing tower 01 You may arrange | position between.
[0117]
The lateral arrangement of the splicing device 05 can again be considered by itself, but also has special advantages when associated with one or more of the advantageous components listed above. It can be demonstrated.
