    PRINTING PRESS FEEDED WITH ADAPTED SHEET TO MAKE A FRONT-BACK PRINT OF THE INDIVIDUAL SHEETS
    TECHNICAL FIELD OF THE INVENTION [001] The present invention generally relates to a sheet fed printing press adapted to perform double-sided printing of individual sheets, in particular for the production of security documents such as bank notes, comprising one or more printing units each adapted to carry out simultaneous double-sided printing of the sheets, each printing unit including two printing cylinders that cooperate with each other and form a printing narrowing, where both sides of the sheets are printed simultaneously, the two printing cylinders each collect ink patterns from at least two associated plate cylinders. The invention particularly relates to a printing press which preferably comprises a printing unit with at least one printing group designed to print a first side and / or a second side of the substrate by collecting different prints or ink patterns in their respective colors in a cylinder, for example, a collection cylinder, before being printed on the substrate.
    BACKGROUND OF THE INVENTION [002] Such printing presses are known as in the art, in particular from European Patent Publication No. EP 0 949 069 A1 and International PCT Publications Nos. WO 2007/042919 A2, WO 2007/105059 Al, WO 2007/105061 Al, WO 2008/099330 A2, WO 2014/056711 Al, WO 2016/042482 A2 and WO 2016/071870 Al, whose publications are all
    Petition 870190078844, of 08/14/2019, p. 8/139
    2/38 incorporated herein by reference in its entirety. International PCT Publication No. WO 2007/042919 A2, in particular, describes a two-sided offset printing press adapted to perform simultaneous front-facing printing of sheets that further comprise an additional printing group placed upstream of a group main printing press.
    [003] Figures 1 and 2 illustrate such a two-sided printing press that is adapted to perform simultaneous double-sided printing of S sheets, as generally used for the production of bank notes and as security documents, whose printing press is designated globally by reference number 100. Such printing press is, in particular, marketed by the present applicant under the product designation Super Simultan® IV. The basic configuration of the printing press 100 shown in Figures 1 and 2 is similar to that shown and discussed with reference to Figure 1 of PCT International Publication No. WO 2007/042919 A2. This type of printing press is generally referred to as a so-called Simultan (or Simultan offset) press due to the fact that several colors are collected in a common blanket before being transferred simultaneously to the S sheets.
    [004] This printing press 100 comprises a printing unit 2, which is specifically adapted to perform the simultaneous double-sided printing of S sheets (according to the offset printing principle so-called Simultan) and comprises, as is typical in the art, two blanket cylinders (or printing cylinders) 5, 6 that rotate in the directions indicated by the arrows and between which the leaves
    Petition 870190078844, of 08/14/2019, p. 9/139

    S are fed to receive multicolored prints on both sides, that is, on the front and back sides. In this example, mat cylinders 5, 6 are three-segment cylinders that are supported between a pair of side frames designated by reference number 20. Mat cylinders 5, 6 receive and collect the different ink patterns in their respective colors from plate cylinders 15 and 16 (four on each side), which are distributed around a portion of the circumference of the blanket cylinders 5, 6. These plate cylinders 15 and 16, which each carry a plate corresponding printing, are themselves covered by ink using corresponding inking devices 25 and 26, respectively. The two groups of inking devices 25, 26 are advantageously supported on two inking carts 21, 22 which can be moved close to or away from the centrally located plate cylinders 15, 16 and blanket cylinders 5, 6.
    [005] As is known in the art, each printing plate is wound around the corresponding plate cylinder 15, 16 and fixed, at its front and rear ends, by means of an adjoining plate fixing system, whose fixing system of plate is located in a corresponding cylinder slot of the plate cylinder (for example, see International Publications (PCT) Nos. WO 2013/001518 Al, WO 2013/001009 Al and WO 2013/001010 A2, which are also incorporated by reference in your totality).
    [006] S sheets are fed from a sheet feeder 1 on a feeder table 1 * located near the printing unit 2 (on the side
    Petition 870190078844, of 08/14/2019, p. 10/139
    4/38 right in figures 1 and 2) for a succession of transfer cylinders 9, 8 ', 10 (three cylinders in this example) placed upstream of the blanket cylinders 5, 6. While being transported by the transfer cylinder 8' , the S sheets receive a first impression on a first side of the S sheets (ie, upper side - or front, in the illustrated example, whose side is identified by a black triangle in the drawings as opposed to the lower side - or back, which is identified by a white triangle), which uses an additional printing group, the transfer roller 8 'performs the additional function of printing roller. This additional printing group consists of, in addition to the transfer roller 8 ', a mat roller 8 (a two-segment roller in this example) that collects the inks from two plate cylinders 18 that are covered by ink using corresponding inks 28. The inking devices 28 are advantageously supported on an inking cart 24 which can be moved close to or away from the plate cylinders 18 and the blanket cylinder 8. The S sheets that are printed by means of the group of inks Additional prints are first dried / cured by a drying / curing unit (designated by reference number 50 in Figure 2), while being transported by the sheet transfer roller 8 ', before being transferred to the main printing group located downstream. This drying / curing unit 50 can in particular be a UV curing device, such as a UV-LED curing device.
    [007] In the example of Figures 1 and 2, the sheets S are transferred to the cylinder surface of blanket 5, where a leading edge of each sheet is maintained by means of
    Petition 870190078844, of 08/14/2019, p. 11/139
    5/38 appropriate claws located in cylinder slots between each segment of the blanket cylinder 5. Each sheet is thus transported by the blanket cylinder 5 for narrowing printing between the blanket cylinders 5 and 6, where the front-back printing simultaneous occurs. Once printed on both sides, the printed sheets S are then transferred, as is known in the art, to a sheet transport system 3 (such as a chain grab system with spaced grab bars) for distribution in a leaf distribution unit 4 comprising multiple (e.g. three) distribution stack units 41, 42, 43. The reference number 31 in Figure 2 designates a pair of chain wheels located at the upstream end of the sheet transport 3.
    [008] In the example of Figures 1 and 2, the first and second transfer cylinders or drums 11, 12, such as drums or suction cylinders, are interposed between the leaf transport system 3 and the blanket cylinder 5. These first and second transfer cylinders 11, 12 are optional (and can therefore be omitted) and are designed to perform inspection of the S-sheets on the front and back sides, as described for example in International application No. WO 2007 / 105059 Al. Reference numbers 61, 62 in Figure 2 designate corresponding inspection cameras (such as line scan cameras) that cooperate with cylinders or drums 11, 12.
    [009] Figure 3 shows, schematically, a partial side view of a printing unit, designated by the reference number 2 * 'of a printing press 100 *,
    Petition 870190078844, of 08/14/2019, p. 12/139
    6/38 according to Figure 3 of PCT International Publication No. WO 2016/071870 Al.
    [010] The printing press 100 * comprises a main printing group consisting of elements 5, 6, 15, 16, 25, 26, including the first and second printing cylinders 5, 6 that cooperate with each other for form a first printing nip between the first and the second printing rollers 5, 6, in which the first and second sides of the sheets S are printed simultaneously, the first printing roll 5 acts as a group transport roll for the sheet main print job. The configuration of the main printing group is just as identical to that of the main printing group illustrated in Figures 1 and 2. In this other example, printing cylinders 5, 6 are likewise three-segment cylinders, which are supported between one pair of side structures 20. The printing cylinders 5,6 receive and collect the different ink patterns in their respective colors from the first and second sets of four plate cylinders 15, respectively 16, which are distributed around a the circumference portion of the printing cylinders 5, 6. These plate cylinders 15 and 16, which each carry a corresponding printing plate, are again covered by ink through corresponding sets of four inking devices 25 and 26, respectively. The two sets of inking devices 25, 26 are likewise supported on two retractable inking carts 21, 22 that can be moved near or away from centrally located plate cylinders 15, 16 and printing cylinders 5, 6 .
    Petition 870190078844, of 08/14/2019, p. 13/139
    7/38 [Oil] In contrast to the configuration illustrated in Figures 1 and 2, the additional printing group comprises third and fourth printing cylinders 7, 8 that cooperate with each other to form a second printing narrowing between the third and the fourth printing rollers 7, 8 where both sides of the sheets S are printed simultaneously, the third printing roll 7 which acts as a sheet transport roller of the additional printing group. Each printing cylinder 7, 8 collects the inks from corresponding sets of two plate cylinders 17, respectively 18, which are covered by ink using corresponding inking devices 27, 28. These two sets of inking devices 27, 28 are also supported on two retractable inking carts 23, 24 that can be moved close to or away from centrally located plate cylinders 17, 18 and printing cylinders 7, 8 (whose carts 23, 24 can be distinguished from or form an integral part of the inking carts 21, 22 of the main printing group).
    [012] As shown in Figure 3, the additional printing group 7, 8, 17, 18, 27, 28 is placed upstream of and above the main printing group 5, 6, 15, 16, 25, 26, the first and second printing cylinders 5, 6, on the one hand, and the third and fourth printing cylinders 7, 8, on the other hand, being aligned along two horizontal planes.
    [013] The main printing group 5, 6, 15, 16, 25, 26 and the additional printing group 7, 8, 17, 18, 27, 28 are coupled to each other by means of a sheet conveyor system intermediary that comprises, in the
    Petition 870190078844, of 08/14/2019, p. 14/139
    8/38 illustrated embodiment, first to third sheet transfer rollers 10 ', 10, 10' interposed between the first and third printing rollers 5, 7. More precisely, sheets S printed in the additional printing group 7, 8 , 17, 18, 27, 28 are transferred from the third printing roller 7, in succession to the first foil transfer roller 10 ', to the second foil transfer roller 10, to the third foil transfer roller 10' , and then to the first printing cylinder 5 of the main printing group.
    [014] On their way to the main printing group 5, 6, 15, 16, 25, 26, S sheets are dried / cured by the first and second drying / curing devices, 51, 52 which cooperate, for example respectively with the first and the second sheet transfer rollers 10 ', 10. The drying / curing devices 51, 52 are generally UV curing devices, in particular UV-LED curing devices.
    [015] The S sheets to be printed are fed in succession from the sheet feeder (not shown in Figure 3) on the feeder table 1 * where they are conventionally aligned before being fed in a succession of, for example, three sheet transfer cylinders 9, 9 ', 9 in the feed. As shown in Figure 3, the S sheets are fed in succession by the sheet transfer rollers 9, 9 ', 9 to the third printing roller 7. The S sheets thus receive the first and second impressions from both sides that are carried out simultaneously in the printing narrowing between the third and fourth printing cylinders 7, 8 of the printing group
    Petition 870190078844, of 08/14/2019, p. 15/139
    9/38 additional and in the printing narrowing between the first and second printing rollers 5, 6 of the main printing group.
    [016] Once fully printed, S sheets can likewise be inspected on both sides using an inspection system 11, 12, 61, 62 similar to that described with reference to Figures 1 and 2, and then , transferred to the sheet transport system 3 for distribution to the sheet distribution unit (not shown in Figure 3).
    [017] In the examples in Figures 1 to 3, it can be seen that the sheet path runs through the printing unit 2, respectively, 2 *, from top to bottom. A limitation of the printing presses in Figures 1 to 3 lies in the fact that the expansion possibilities are somewhat limited by the installation height available in the relevant printing jobs where the printing press is to be installed. The basic configuration of the printing presses in Figures 1 to 3 is, however, a huge advantage in terms of color-to-color registration accuracy thanks to the fact that such printing presses are designed to operate according to the printing process in Simultan's offset.
    [018] Figure 4 shows another known sheet fed printing press, designated globally by reference number 100 ** 'for the S-sheet double-sided printing press, as described in the U.S. Patent, for example. North American No. 5,555,804, which another publication is also incorporated here by reference in its entirety. This type of printing press, which (like the printing presses in Figures 1 to
    Petition 870190078844, of 08/14/2019, p. 16/139
    10/38
    3) does not require any reverse sheet system to print both sides of the S sheets, it is generally referred to as a so-called double-stage press (doubledecker). Other examples of such two-stage presses are described, for example, in Japanese Patent Publication No. JP 2004-034641 A and European Patent Publications Nos. EP 0 906 826 A2, EP 0 976 555 Al, EP 1 060 883 Al, EP 1 323 529 Al, EP 2 357 083 Al, EP 2 484 523 Al, EP 2 583 828 Al, EP 2 647 505 Al, EP 2 653 309 A1, EP 2 756 952 A1 and EP 2 845 728 A2.
    [019] In contrast to the examples in Figures 1 to 3, the printing press in Figure 4 is not adapted for simultaneous double-sided printing of the S sheets. Instead, the S sheets are fed in succession from the sheet feeder 1 (through the feeder table 1 * and the sheet transfer roller 9 in the feed) through a series of printing units 2.1 through 2.8 that are designed to print the front and back sides of the sheets S of a alternately and consecutively. More precisely, printing units 2.1, 2.3, 2.5 and 2.7 are designed to print the upper side (front) of the S-sheets, while printing units 2.2, 2.4, 2.6 and 2.8 are designed to print the lower side (back). of the S leaves.
    [020] As shown in Figure 4, the printing units 2.1, 2.3, 2.5, 2.7 each comprise a printing cylinder 10.1 to 10.4 (located below the path of the S sheets), which cooperates with an associated blanket cylinder 5.1 to 5.4 (located above the path of the S sheets), whose blanket cylinder receives a relevant ink pattern to be transferred to the front side of the S sheets from
    Petition 870190078844, of 08/14/2019, p. 17/139
    11/38 of a corresponding plate cylinder 15.1 to 15.4 covered by ink using a 25.1 to 25.4 inking machine. Once printed by printing units 2.1, 2.3, 2.5, 2.7, S sheets are transferred from the relevant printing cylinder 10.1 to 10.4 to the relevant printing cylinder 11.1 to 11.4 of the printing unit located downstream 2.2, 2.4, 2.6, 2.8, whose printing cylinder 11.1 to 11.4 is located above the path of the S sheets. A series of eight printing cylinders 10.1 to 10.4, 11.1 to 11.4 is thus provided to transport the S sheets consecutively through the eight successive printing units 2.1 to 2.8.
    [021] The printing units 2.2, 2.4, 2.6, 2.8 are basically the mirror image of the printing units 2.1, 2.3, 2.5, 2.7 and likewise each comprise a 6.1 to 6.4 blanket cylinder ( located in this case below the path of the sheets S) that cooperates with the associated printing cylinder 11 located above it and receives a relevant ink pattern to be transferred to the back side of the sheets S from a corresponding plate cylinder 16.1 to 16.4 covered by ink using a 26.1 to 26.4 inking machine.
    [022] Once printed by the last printing unit 2.8 in sequence, the sheets S are transferred to a sheet transport system 3 via a final transfer roller 13 for transport and distribution to the sheet distribution unit 4. Only one distribution stack unit 41 is shown in Figure 4, but multiple distribution stack units can be contemplated as in the example in Figure 1.
    Petition 870190078844, of 08/14/2019, p. 18/139
    12/38 [023] In the example in Figure 4, you will appreciate that the sheet path runs through print units 2.1 to 2.8 from right to left along a substantially horizontal direction, instead of vertically as in the examples in Figures 1 to 3. In addition, the S sheets are submitted, in the example in Figure 4 to eight consecutive printing steps, one in each printing unit 2.1 to 2.8, whereas, in the examples in Figures 1 to 3, the S sheets are submitted to only two consecutive printing steps, that is, a first printing step in the additional printing group and a subsequent second printing step in the main printing group. In this regard, one of the main limitations of the type of printing press represented in Figure 4 lies in the increase in sheet distortion (as each printing step adds to the distortion of S sheets) which has a negative impact on color registration accuracy at color. In addition, while the printing press of Figure 4 is flexible in which additional printing units can be provided, the machine footprint is necessarily increased as a result of such an addition.
    [024] There is therefore a need for an improved printing press configuration that is flexible in terms of modularity, while maintaining as high as possible the high color registration accuracy of the Simultan presses mentioned above.

    SUMMARY OF THE INVENTION [029] A general objective of the invention is to improve known printing presses of the type mentioned above.
    [030] More precisely, an objective of the present invention is to provide such a printing press that it is adapted to perform a double-sided printing of individual sheets with a high accuracy of color to color registration while being flexible in terms of the possibility of expansion.
    [031] Another objective of the present invention is to provide such a printing press where the machine's operability and accessibility are not compromised.
    [032] These objectives are achieved thanks to the printing press defined in the claims. In
    Petition 870190078844, of 08/14/2019, p. 20/139
    14/38 in particular, a sheet fed printing press adapted to perform a double-sided printing of the individual sheets is provided, in particular for the production of security documents such as bank notes, which comprise two or more printing units each adapted to carry out simultaneous double-sided printing of the sheets, each printing unit including two printing cylinders that cooperate with each other and form a print narrowing, where both sides of the sheets are simultaneously printed, the two printing cylinders each collect ink patterns from at least two associated plate cylinders. According to the invention, the two printing cylinders are located one above the other in such a way that the sheets run laterally through each printing unit from a first side side located upstream of the print nip to a second side side opposite the first side and located downstream of the print narrowing.
    [033] Instead or preferably in addition to the above, in a preferred embodiment, a printing group of a respective printing unit is designated as a printing group for indirect printing, such as indirect lithographic printing, that is, offset printing, or indirect relief printing, for example, letterpress printing, or a combination of both.
    [034] A so-called collection printing group is designed to print at least one side of the substrate, firstly collecting multiple prints or patterns from several plate cylinders on one printing cylinder, for example, a so-called printing cylinder collect,
    Petition 870190078844, of 08/14/2019, p. 21/139
    15/38 before being printed, as an image collected as a whole on the substrate.
    [035] The printing unit or in particular the preferred collection printing group can be configured with at least one or more inking devices and associated plate cylinders designed to allow and / or perform an offset printing, which comprises, for example, a damping system and / or at least the possibility of placing lithographic printing plates on the respective plate cylinder. Although these inking devices can possibly also be performed for letterpress printing without or with the damping system inactive and with a letterpress printing plate, the printing group or printing unit is nevertheless designated - at least in part - as an offset printing group respectively printing unit. In addition to plate cylinders and inking devices designed to allow and / or perform offset printing, a collection group or printing unit may comprise additional plate cylinders with associated inking devices designed to perform only other types of printing especially , for example, letterpress printing. In this sense, the collection printing unit or group above should be understood as an offset printing unit or group, provided that at least one, more or all of its corresponding plate cylinders and inks are or are designated to allow and / or perform offset printing.
    [036] In an alternative embodiment, the printing unit or in particular the collection printing group can be configured with only one or more plate cylinders
    Petition 870190078844, of 08/14/2019, p. 22/139
    16/38 and associated inking devices designed to allow and / or perform indirect relief printing, for example, such as letterpress printing.
    [037] The additional advantageous embodiments of the invention form the subject matter of the dependent claims and are discussed below.

    DETAILED DESCRIPTION OF THE PERFORMANCE OF THE INVENTION [046] The present invention will be described in the particular context of a sheet fed two-sided printing press adapted to perform offset printing on both sides of the sheets and comprising one or more printing units. each showing a Simultan configuration (2) in (2). It should be appreciated, however, that the invention is not limited to this particular configuration and can be extended to any Simultan configuration (m) in (n) where the variables men are integers greater than or equal to 2. That said, the configurations printing presses, as shown in Figures 5 to 7 are particularly preferred, as they exhibit a reasonably simple configuration while still allowing unprecedented expansion capabilities and great modularity. As this will be appreciated from reading the following description of embodiments of the invention, the preferred Simultan printing unit configuration (2) in (2) would allow any printing press configuration for two-sided printing (2 x N) in (2 x N) (N being a number

    18/38 integer equal to the number of Simultan (2) printing units in (2) individual. The expression configuration (m) in (m) is to be understood as a simultaneous two-sided printing with color separations m or structures printed on each side and / or a configuration of a two-sided printing press, the printing unit or group comprising a first set of m plate cylinders that cooperates with a first printing cylinder and a second set of m plate cylinders that cooperates with a second printing cylinder, whose first and second printing cylinders cooperate to create a common impression narrowing.
    [047] The term printing group will be used for the equipment, for example, the cylinders, rollers and means of the inking unit (s), which belong to a printing narrowing for at least one printing. side of the substrate. A double-sided printing group for this purpose is a special printing group with two printing groups, one on or for each side of the substrate path, sharing the same print narrowing for printing simultaneously on both sides of a substrate. pass through and act mutually with their printing cylinders as back pressure cylinders for the other printing group. It is to be understood that several printing groups can be arranged in the same printing unit, with these printing groups, for example, being arranged on walls of individual structure or of several parts.
    [048] In the context of the present invention, the term printing cylinder (s) will be used to designate the relevant cylinders of the printing press which cooperate

    19/38 directly with the first or second side of the S sheets to transfer the print patterns to it. This expression is, however, interchangeable with the expression blanket cylinder, it being understood that the relevant printing cylinders each carry a number of printing blankets. In the embodiments of Figures 5 to 7, these printing cylinders (or mat) are designated by reference numbers 105 and 106 and are cylinders of two segments. The printing cylinders can, however, have any suitable size or diameter.
    [049] The terms top side (or front side) and bottom side (or back side) are used in the following description to designate the two opposite sides of the S sheets to be printed. More precisely, in the illustrations in Figures 1 to 7, the top / front side designates the side of the leaves that is identified by the black triangles in the drawings, while the bottom side / back designates the side of the leaves that is identified by the white triangles in the drawings. These expressions are, however, interchangeable.
    [050] Figure 5 schematically shows a partial side view of a printing unit, designated by reference numeral 200, of a printing press according to an embodiment of the invention. Although only one printing unit 200 is shown in Figure 5, the relevant printing press can comprise any desired number of printing units 200 located one after the other, all sharing the same or substantially the same configuration. A sheet feeder conveyor system, sheet feeder and sheet distribution unit are not shown in Figure 5, but must be appreciated

    20/38 that such components - which are known as such in the art - would generally be provided to ensure feeding S sheets to the (first) printing unit in the sequence and transporting the printed S sheets from the last printing unit in the sequence for the distribution unit. In addition, any additional printing or processing unit can be provided upstream or downstream of any of the printing units 200, including, but not limited to, an inspection system to inspect one or both sides of the sheets, a coating unit to coat one or both sides of the sheets with, for example, a varnish, or any other printing unit that operates according to any desired printing process (such as intaglio printing, silkscreen printing, letterpress printing, etc.) .
    [051] The printing unit 200 illustrated in Figure 5 is specifically designed to be able to be coupled to at least one other, the identical printing unit 200, either on the upstream side and / or on the downstream side. More precisely, the printing unit 200 includes two printing cylinders 105, 106 which cooperate with each other and form a printing nip, where both sides of the S sheets are simultaneously printed. These two printing cylinders 105, 106 are located one above the other in such a way that the sheets S run laterally (here from right to left), through the printing unit 200 from a first side side, designated by reference number 201a, located upstream of the print narrowing formed by the two printing cylinders 105, 106 for a second side, designated by the number of
    Petition 870190078844, of 08/14/2019, p. 27/139
    21/38 reference 201b, opposite the first side side 201a and one located downstream of the print narrowing. In the illustrated example, the first printing cylinder 105 acts as a sheet transport cylinder and transports the individual sheets S to and passes through the print narrowing.
    [052] The second printing cylinder 106 can alternatively be designated as the sheet transport cylinder, in which case the transport of the S sheets to and away from the narrowing of printing between the two printing rollers
    105, 106 would have to be changed accordingly. In the context of the present invention, it does not really matter whether the S sheets are transported by the first or the second printing cylinder.
    [053] As illustrated in Figure 5, the printing unit 200 is preferably designated as a Simultan unit (2) in (2) comprising the first and second plate cylinders 15A, 15B that cooperate with the first cylinder of printing 105 and the third and fourth plate cylinders 16A, 16B which cooperate with the second printing cylinder
    106. In the illustrated example, the first and second plate cylinders 15A, 15B are consequently located above the first impression cylinder 105, while the third and fourth plate cylinders 16A, 16B are located below the second impression cylinder. 106. Each of the plate cylinders 15A, 15B, 16A, 16B is covered by ink using a corresponding inking device 25A, 25B, 26A, 26B, whose inking devices 25A, 25B, 26A, 26B can advantageously be assigned to each comprising two sources of ink, the configuration of which is useful for rainbow printing.
    Petition 870190078844, of 08/14/2019, p. 28/139
    22/38 [054] Each inking device 25A, 25B, 26A, 26B is conveniently designed to extend along a substantially vertical direction above or below the associated plate cylinder 15A, 15B, 16A, 16B, thereby releasing the space to gain access to the plate cylinders 15A, 15B, 16A, 16B for the purpose of, for example, mounting or removing the printing plates from the circumference of the plate cylinders 15A, 15B, 16A, 16B. For each ink source, at least one reference plane is not defined, which crosses with that respective ink source and that contains the axis of rotation of the plate cylinder 15A, 15B, 16A, 16B associated with that respective ink source. An inking apparatus designed to extend along a substantially vertical direction above or below the associated plate cylinder 15A, 15B, 16A, 16B is preferably characterized by the fact that for at least one ink source of that inking apparatus and preferably, for each ink source of that inking device, the at least one respective reference plane contains at least one straight reference line, and in which this at least one straight reference line is oriented perpendicular to the axis of rotation of the plate cylinder 15A, 15B, 16A, 16B associated with that respective ink source and wherein that at least one straight reference line with a vertical straight line limits an angle that is less than 45 ° more preferably less than 35 ° , more preferably less than 25 ° and more preferably less than 20 °. Alternatively, the inking apparatus 25A, 25B, 26A, 26B can be located on corresponding inking carts designed to be retractable away from plate cylinders 15A, 15B, 16A, 16B.
    Petition 870190078844, of 08/14/2019, p. 29/139
    23/38 [055] In the illustrated example, the first and second printing cylinders 105, 106, the corresponding plate cylinders 15A, 15B, 16A, 16B, as well as the associated inking devices 25A, 25B, 26A, 26B ( unless the latter is supported on the inking carts as mentioned above) are supported between a pair of side frames 201, whose pair of side structures 201 forms corresponding connection interfaces on the first and second side sides 201a, 201b at the entrance / side upstream and at the outlet / downstream side of the printing unit 200. Preferably, the pair of side frames 201 also supports a first sheet transfer element 95, in particular a first sheet transfer cylinder 95, which cooperates with the first printing cylinder 105 upstream of the printing narrowing and at least a second sheet transfer element 110, in particular a second sheet transfer cylinder 110, which cooperates with the first impression cylinder 105 downstream of the print narrowing. Even more preferably, the pair of side frames 201 also supports a third sheet transfer element 120, in particular a third sheet transfer cylinder 120, which cooperates with the second sheet transfer cylinder 110 to take sheets S from of the second sheet transfer roller 110. In other words, in the example in Figure 5, the sheets S travel laterally through the printing unit 200 from a first sheet transfer location (or sheet entry location) TI located on the first side side 201a (i.e., the sheet transfer site for the first sheet transfer roller 95) to a second sheet transfer site (or location
    Petition 870190078844, of 08/14/2019, p. 30/139
    Sheet outlet 24/38) T2 located on the second side side 201b (i.e., the sheet transfer site from the third sheet transfer roller 120), the sheets S being transported in succession by means of rollers 95, 105, 110 and 120.
    [056] The sheet transfer elements 110, 120, 95 are shown exemplarily as the sheet transfer cylinder 110, 120, 95 throughout the drawings. However, at least one of the sheet transfer elements 110, 120, 95 or a plurality of the sheet transfer elements 110, 120, 95 or all of the sheet transfer elements 110, 120, 95 are alternatively incorporated as one another type of sheet transfer element 110, 120, 95, for example, a chain claw system 110, 120, 95 and / or a claw system 110, 120, 95 that is movable by a transport element, such as such as a transfer drum or drum. In particular, at least two separate clamping systems 110, 120, 95 spaced apart in a circumferential direction around a common transfer cylinder 110, 120, 95 which carries these at least two clamping systems 110, 120, 95 can be considered as at least two transfer elements 110, 120, 95. Preferably, at least one of the sheet transfer elements 110, 120, 95 is incorporated as a grab system or a chain grab system 110, 120 , 95 or as a sheet transfer cylinder 110, 120, 95 comprising at least one gripper system. More preferably, at least two of the sheet transfer elements 110, 120, 95 are incorporated as a respective clamping system and / or as a respective system
    Petition 870190078844, of 08/14/2019, p. 31/139
    25/38 of chain claw 110, 120, 95 and / or as a respective leaf transfer cylinder 110, 120, 95 comprising at least one claw system. In an exemplary embodiment, the first sheet transfer element 95 is incorporated as a first sheet transfer cylinder 95 and / or the second sheet transfer element 110 is incorporated as a second sheet transfer cylinder 110 and / or the third sheet transfer element 120 is incorporated as a third sheet transfer cylinder 120.
    [057] According to the preferred embodiment shown in Figure 5, the first and second drying or curing units 510, 520 are further located downstream of the printing narrowing of at least one and preferably of the respective printing unit 200 ; 200.1, 2001.2; 200.1 *, 200.2 * between the two printing rollers 105, 106, that is, over a corresponding portion of the circumference of the second and third sheet transfer rollers 110, 120, respectively, in which the sheets S are transported. The second drying or curing unit 520 may alternatively be cooperating directly with the circumference of the first printing cylinder 105 immediately after the printing narrowing in order to dry or cure the back / bottom side of the S sheets. The drying or drying units curing 510, 520 are preferably UV curing units, such as UV-LED curing units. The second and third sheet transfer rollers 110, 120 can alternatively be incorporated again like any other type of sheet transfer elements 110, 120.
    [058] Preferably, the transfer location of the IT sheet for the first element of
    Petition 870190078844, of 08/14/2019, p. 32/139
    26/38 sheet transfer 95 or the first sheet transfer cylinder 95 and the sheet transfer location T2 away from the third sheet transfer element 120 or third sheet transfer cylinder 120 is located at the same height, as illustrated in Figure 5, thus allowing a direct coupling of two identical printing units 200 one after the other, in the case of the third sheet transfer element 120 or third sheet transfer cylinder 120 of the printing unit located upstream 200, which is made to cooperate directly with the first sheet transfer element 95 or the first sheet transfer cylinder 95 of the printing unit located downstream 200.
    [059] Such a configuration where at least two identical printing units 200.1, 200.2 are coupled directly to each other is shown in the realization of Figure 6. In fact, Figure 6 is a schematic partial side view of a printing press designated by reference number 1000 and comprising at least two printing units 200.1, 200.2 of the same type as previously described in connection with Figure 5. Components 15A, 15B, 16A, 16B, 25A, 25B, 26A, 26B, 95, 105, 106, 110, 120, 201, 510, 520 in Figure 6 are the same components as described in connection with Figure 5 and therefore do not need to be described again. It is sufficient to understand that the two printing units 200.1, 200.2 are coupled directly to each other, with the second side side 201b of the first printing unit 200.1 being coupled to the first side side 201a of the second printing unit 200.2. In the illustration in Figure 6, the first side side 201a of the first printing unit 200.1 is shown
    Petition 870190078844, of 08/14/2019, p. 33/139
    27/38 coupled to a feeder table 1 * of a sheet feeder, whose feeder table 1 * is provided with a leaf transfer element 90 or leaf transfer cylinder 90 that acts as feed and receives the individual S sheets of, for example, a grab arm swing system. The second side side 201b of the second printing unit 200.2 (not shown in Figure 6) can likewise be coupled to a third printing unit in a similar manner to the first and second printing units 200.1, 200.2.
    [060] The last printing unit in the sequence of printing units can also be coupled to any suitable sheet conveyor system for transporting the printed S sheets to a corresponding sheet distribution unit in a manner similar to that shown, for example example, in Figure 4, if a suitable sheet transfer element or sheet transfer cylinder can also be interposed between the third sheet transfer element 120 or the third sheet transfer cylinder 120 of the last printing unit in the sequence and the upstream end of a sheet transport system 3 (like the sheet transfer cylinder 13 shown in Figure 4).
    [061] Although this is not specifically illustrated, an inspection system similar to the inspection system 11, 12, 61, 62 shown in Figures 1 to 3 can also be provided downstream of the last printing unit in order to inspect both sides of the printed S sheets.
    [062] Figure 7 shows another embodiment of a printing press, designated by the reference number
    Petition 870190078844, of 08/14/2019, p. 34/139
    28/38
    1000 *, according to the invention and comprising at least two printing units 200.1 *, 200.2 *, which are located one after the other. As in the embodiment of Figure 6, an odd number of sheet transfer elements, in particular sheet transfer cylinders, i.e. transfer cylinders 110, 120 and 95, are provided downstream of the printing narrowing of the first printing unit 200.1 * and upstream of the print narrowing of the second printing unit 200.2 * to transfer the sheets S from the first printing unit 200.1 * to the second printing unit 200.2 *. The only difference in relation to the realization of Figure 6 lies in the fact that not all sheet transfer elements 110, 120, 95 or sheet transfer cylinders 110, 120, 95 are an integral part of the first and second printing units 200.1 *, 200.2 *. Instead, in the example of Figure 7, only the first sheet transfer element 95 or sheet transfer cylinder 95 and the second sheet transfer element 110 or sheet transfer cylinders 110 are supported between the pair of side frames 201 * of the two printing units 200.1 *, 200.2 *, the third sheet transfer element 120 or sheet transfer cylinder 120 which is supported in this case in an intermediate structure 205 which is interposed between the second side side 201b * of the first printing unit 200.1 * and the first side side 201a * of the second printing unit 200.2 *. In the illustrated example, the second side side 201b * of the second printing unit 200.2 * is likewise coupled to an intermediate structure 205 that supports the third sheet transfer element 120 or the third cylinder

    [063] From a functional perspective, the
    components 1 * , 15A, 15B, 16A, 16B, 2 5A, 25B, 26A, 26B, 90, 95, 105, 106, 110, 120, , 201 * , 205, 510, 520 at Figure 7 fulfill the same function that the components 1*, 15A, 15B, 16A, 16B, 25A, 25B,520 described 26A, 26B, in connection 90, 95with the , 105,Figure 106,6. 110, 120, 201, 510,
    [064] Various modifications and / or improvements can be made to the above described achievements without departing from the scope of the invention as defined by the appended claims.
    [065] First of all, either of the two printing cylinders 105, 106 can be designated as a sheet transport cylinder and the invention is therefore not limited to the illustrated embodiments, where the sheet transport cylinder is located above of the sheet path S. The sheet transport roller can also be located below the sheet path S. In one embodiment, the sheet transport roller of a first printing unit is located above the sheet path S as a roller The sheet transport roller of a second adjacent printing unit is located below the path of the sheets S. In another embodiment, the sheet transport roller of a first printing unit is located below the path of the sheets S while a roller for transporting the sheets. sheet of a second adjacent printing unit is located above the path of the S sheets.
    [066] Likewise, while Figures 6 and 7 show that the three sheet transfer rollers 110,
    Petition 870190078844, of 08/14/2019, p. 36/139
    30/38
    120, 95 are provided downstream of the printing narrowing of the first printing unit 200.1, respectively, 200.1 *, and upstream of the printing narrowing of the second printing unit 200.2, respectively 200.2 *, to ensure the transfer of the S sheets from from one printing unit to another, any number of at least two sheet transfer elements or rollers would be convenient. The number of at least two transfer elements or rollers is preferably any odd number of transfer elements or rollers and more preferably an odd number of at least three transfer elements or rollers. The illustrated examples are advantageous in that the at least two sheet transfer elements 110, 120, 95 and, in particular, the at least three sheet transfer elements 110, 120, 95 or cylinders 110, 120, 95 ensure sufficient spacing between the two successive printing units and accessibility to all relevant parts of the printing presses, in particular the plate cylinders 15A, 15B, 16A, 16B and the drying / curing units 510, 520. Alternatively, the three sheet transfer elements 110, 120, 95 or cylinders 110, 120, 95 could be replaced by another number, in particular another odd number of sheet transfer elements or cylinders, for example five sheet transfer cylinders of the size that the sheet transfer roller 95 shown in Figure 6 and / or Figure 7.
    [067] It should also be appreciated that all relevant printing units do not necessarily have to be strictly identical. The achievements described here, in
    Petition 870190078844, of 08/14/2019, p. 37/139
    However, they have a great advantage in that complete modularity is ensured, as each individual printing unit is designated as a basic building block that can be added or removed from the printing press without major difficulties.
