    This invention relates to a combination sheet rotary printing press for printing securities, in particular banknotes.
    A known printing machine, the printing press of which consists of an offset cylinder that is rolled up by several offset cylinders and a pressure cylinder interacting with it and therefore allows only one side of the sheet to be printed. The offset cylinder and the transfer cylinder interact with the pressure cylinder, the sheet clamps of which press the sheet from the offset cylinder and carry it along with the pressure cylinder to the circumference until the gripping of the transfer cylinder. In this case, the portion of the circle between the offset cylinder and the transfer cylinder, in which the sheet is carried along the pressure cylinder, is much more than half the circumference of the pressure cylinder.

    pa. In addition, the transfer cylinder acts simultaneously as the cylinder of the sheet turning device and for this reason has a size corresponding to the length of two sheets, so that its diameter is twice the diameter of the form cylinder and the offset cylinder, which usually have a size corresponding to one single sheet, while the offset cylinder and the pressure cylinder are fitted to the three-sheet format and therefore have a diameter three times larger than the forme cylinder and the transfer cylinder.
    The sheet feeder in a known combination press consists, as mentioned, of an indirectly printing cylinder interacting with a pressure cylinder for turning the sheets, which acts as a transfer cylinder, for turning the sheets of a small cylinder that is adapted to the size of the sheet. , from twice the size of the drying cylinder, near the circumference of which the drying device is located, from the register-corrected grab of the single cylinder, as well as from the transporting cylinder, which transfers the sheets to the pressure cylinder of the printing machine for metallographic printing and the size of which, as well as the size of the register cylinder, corresponds to the size of the sheet. Since this transporting device, when a system of valuable grippers is abandoned, it works only with interacting cylinders, in which the sheet goes from one cylinder directly to the next cylinder, during the whole process of transporting the sheet between indirectly printing press and metallographic printing press A perfect register is very reliable, so that in general, after a sheet is turned over, a register can be corrected in all cases, and then estvl is automatically given cylinder.
    With the aid of the aforementioned known machine, one or the same side of the sheet can be either printed, without turning the sheet, using multi-color offset printing and using multi-color printing from steel engravings, or, when turning the sheet, one side of the sheet receives a multi-color offset printing, and the other the side of the sheet is a multi-color print from steel engravings.
    The invention is based on the task of creating a combination sheet rotary press while retaining a single cylinder built
    devices for transporting sheets in such a way that the indirect printing press can operate in duplex mode and form one multi-color image on both sides of the sheet.
    Due to the design and location of the transfer and transfer cylinders in an indirectly printing press uncovered free sheet
    a portion of the circumference of the second cylinder, made in the form of an offset cylinder, is so enlarged that several, in particular, three or four offset cylinders and their inks can be installed along this portion of the circumference, so that a sheet that passes indirectly through the printing machine simply a multi-color print not only on the side facing the first offset cylinder, but also on the side adjacent to the second offset cylinder. With these multi-color prints, in the case of banknotes, it is preferably a non-counterfeit multi-color background, which on one side of the sheet is complemented by a multi-color printing from steel engravings depicting the main pattern on the metallographic apparatus. So by using this printed
    machines in one pass can make perfect banknote prints, in which the front side has a multicolor basic sample and a non-counterfeit background, and the reverse side
    It has a non-counterfeit background, as it is, in particular, usually adopted when printing banknotes of lower value. However, in addition to this, a main sample can also be created on the back
    due to the fact that at least one of the form cylinders of an indirectly printing printing apparatus is equipped with a moistened offset form having a basic pattern, preferably in the form of an intaglio printing form.
    Appropriate embodiments of the printing press according to the invention are derived from the dependent claims. A particularly preferred embodiment, according to which the indirect printing press is reversible and which allows one to create a multi-color offset printing on one side of the sheet depending on the setting or to produce printing from several forms.
    The purpose of the invention is the expansion of technological capabilities by providing various types of single and double-sided printing.
    FIG. 1 shows an example of a combination rotary sheet printing press, in which an indirect printing press provides double-sided multi-color offset printing; in fig. 2 — a printing machine with a different sheet feeding system and with a different arrangement of the forme cylinders on the upper offset cylinder of the indirect printing press; in fig. 3 - a printing machine in which an indirect printing press on one side of a sheet provides multicolor offset printing and on the other side of the sheet a colorful print from several forms; in fig. 4-6 is the same in which the indirect printing press is reversible and can occupy three different working positions to obtain different printing combinations, with the lower half of the printing apparatus taking up in accordance with FIG. 4 position for printing from several forms, in accordance with FIG. 5, the first position for offset printing and in accordance with FIG. 6 second position for offset printing.
    The combined rotary sheet printing machine (Fig. 1) consists of an indirect printing press A, through which the sheets first pass, from the after-transporting device B for transporting the sheets, which is made up exclusively of cylinders, and from the printing machine, in which Sheets fall at the end of device B for transporting sheets.
    An indirectly printing press A, in the case of which it is a printing press operating in duplex mode, has two interacting offset cylinders 3 and 5 vertically above each other, each of which is in contact with several forme cylinders 12, 15 or 7 , 10, having offset printing forms, and between which the sheets are simultaneously sealed on both sides. With the help of several transport cylinders 1 and a transfer cylinder 2, which interacts with the offset cylinder 3, the sheets fall on the offset cylinder 3, where they are carried away by its gripping sheets. The direction of rotation of both offset cylinders 3 and 5 is indicated by arrows. After
    The sheet, enlarged by the offset cylinder 3, has passed the printing position between the two spray cylinders. It is gripped by the transfer cylinder 18, which interacts with the offset cylinder 3, which is the first transport cylinder of the device B for transporting sheets. The portion of the circle between the transfer cylinder 2 and transfer cylinder 18, in which the sheet is carried by the offset cylinder 3, is equal in size to a maximum of half of its circumference and in the considered example extends approximately by
    5 135 ° C. In general, it is preferred that this portion of the circumference extends through an angle of less than about 150 ° C.
    The transfer cylinder 18 has the same diameter as the transfer cylinder 2,
    0 and the forme cylinders 7, 10 and 12, 15, which are usually small, are only plate-carrying cylinders whose circumference is adjusted to the size of the sheet. Offset
    5 cylinders 3 and 5 are respectively designed to receive three sheets and therefore three times as large.
    Due to the design and location of the transfer cylinder 2 and transfer cylinder 18, the uncovered free upper portion of the circumference of the offset cylinder 3 is at least half the circumference of the cylinder, in the example under consideration it extends approximately at an angle of 225 ° C and provides enough space for several plate cylinders, of which, in accordance with FIG. 1, both the forme cylinders 12 are located to the right of the vertical midline and both the forme cylinders 15 are to the left of the vertical midline of the offset cylinder 3.
    In this example, it is assumed that the forme cylinders 12 and 15 carry wetted offset forms. They are rolled up with paint inking unit 13 or 16 respectively and are moistened with a humidifier 131 or 161, respectively. The color units 13 and the dampening units 131 are installed in the stand 14 of the ink apparatus, and the color apparatus 16 in the stand 17 of the ink apparatus .
    Another blanket cylinder 5 interacts with four bearing blanket plates for printing plates, of which, in accordance with FIG. 1 three form cylinders 7 are installed to the right of the centerline and one form cylinder 10 to the left of the vertical centerline of the offset cylinder 5. Again, these form cylinders carry moisturizing offset forms. Three plate cylinders 7 interact with inking units 8 and humidifiers 8 in an exhaust rack 9 of the inking unit, while plate cylinder 10 interacts with the inking unit 11 and the humidifier 111.
    In addition, in accordance with FIG. 1, devices 32 for sucking paper dust are provided near the circumference of the transfer cylinder 2 and the preceding transporting cylinder; these suction devices may also be located near the circumference of at least two successive transporting cylinders 1. In the lower circumference region offset cylinders 3 and 5 are provided, in addition, automatically operating devices 4 or 6 for washing the rubber web, which are naturally in printing mode the printing device occupy a non-working position removed from the offset cylinders.
    The transport device B in this example has nine transport cylinders, namely a transfer cylinder 18, a cylinder 19, four cylinders 20, near the circumference of which are drying devices 21 for drying both printed sides of the sheet, cylinder 22 for turning sheets related to sheet turning, cylinder 23, which acts as a register cylinder and at the same time as part of a sheet turning device, and another cylinder 24, which introduces sheets into apparatus C for metallogs raphic print. All cylinders 18, 19, 20, 23, and 24 have the same size fitted to the sheet, while cylinder 22 for turning the sheets is fitted to the size of two sheets and therefore has a diameter twice as large.
    This device for turning sheets is known. If the sheet which is located on the cylinder 22 rotating in the direction of the arrow does not have to be turned over, then it is taken in the usual manner directly by the cylinder 23 due to the fact that its grippers grab the front edge of the sheet located on the cylinder 22. In the event of turning the sheet, after it has completely passed the gap between the cylinders 22 and 23, it is caught at its trailing edge, installed with the possibility of rotation on the cylinder 23 and
    correspondingly controlled grippers and extends in the direction of the straight arrow F on the cylinder 23, the rear edge of the sheet becoming its front edge, and the cotor is simultaneously freed from the grips of the cylinder 22.
    By its action as a drive cylinder, the cylinder 23 takes care that the possible
    0 deviations of the positions of the sheets from the exact register.
    In the example of FIG. 1, all the cylinders of the transport device B, as well as the transfer cylinder 2 and the transport cylinders 1 located in front of it, are at least approximately horizontally adjacent to each other or in the same horizontal plane.
    0 The metallographic printing apparatus C consists of a printing cylinder 25, onto which a sheet of transporting cylinder 24 falls, interacting with the printing cylinder 25 of the printing cylinder.
    26, which carries the forms for metallographic printing, four patterned rollers 27, which are rolled up by colorful devices 28 in various colors and which are rolled up by paint forms
    0 metallographic printing on the plate cylinder 26, and from the flushing device 30. All the paint apparatus 28 are installed in the exhaust rack 29 of the ink apparatus. The sheets printed in apparatus C for metallographic printing are then received by the transporting system 31, in particular, by a system of chain grippers.
    With the help of the described press, banknotes can be fitted on both
    0 sides, respectively, with a four-color offset print, which is a non-counterfeit background, and, besides, on one side, depending on the setting of the device for turning sheets, a four-color print with steel engravings as the main pattern. If necessary, the other side of the sheet printer A can also be equipped with a main pattern, for which in this case serves one of the plate cylinders, which in this case is equipped with a preferably intaglio printing pattern having a main pattern, the surface of which is out
    5 is moistened with a suitable wetting device so that it does not absorb paint when rolled up with paint.
    The printing machine according to FIG. 2 differs from the printing press according to fig. 1 in that the transport cylinders 1 in accordance with FIG. 1 are replaced by another known sheet feeding system 33, for example, a sheet feeding conveyor belt. At the end of this sheet-feeding system 33, sheets with the help of stop cylinders ZZa and transfer cylinder 2 fall onto the offset cylinder 3. Another difference from the printing press in accordance with FIG. 1 is that in the upper rack 14 of the indirect printing press A, only one plate cylinder 12 with an ink device is installed, but in the other rack 17 of the ink machine, three plate cylinders 15 with ink machines are installed. In this press, a sheet-circumference portion of the offset cylinder 3 extends over an angle of approximately 145 °. All other structural details of the indirect printing apparatus 4, the sheet feeding device B and the metallographic printing apparatus C are the same as in the embodiment according to fig. one.
    In a printing machine according to an exemplary embodiment in accordance with FIG. 3, the lower half of the indirect printing press A prints according to the printing method from several forms, which is also called the Oryol printing method, while the upper half, as in the example in accordance with FIG. 1 and 2, prints using the offset printing method. The sheet feeding system 33 with the stop cylinder ZZa, from which the sheets fall on the transfer cylinder 2, corresponds to the sheet feeding system of the printing machine in accordance with FIG. 2. Only four small transport cylinders are provided in sheet feeding device B in front of cylinder 22 to turn the sheets, namely, transfer cylinder 18 and the next three cylinders 20, and drying devices 21 are located near the circumference of all four small cylinders. The metallographic printing apparatus C corresponds to the embodiments A of FIG. 1 and 2.
    In order to achieve multi-color printing from several forms on one side of the sheet, the lower half of the indirect printing press according to FIG. 3 is made as follows.
    Both offset cylinders 3 and 5 are pressed apart. Adjacent to the blanket cylinder 5, the forme cylinder 10 carries a composite printing plate having a perfect printing pattern. An additional small cylinder in the form of a cylinder 34 is provided between this plate cylinder 10 and the offset cylinder 3 for transferring the image, which is adjacent to both the plate cylinder 10 and the offset cylinder 3. To the right of the vertical center line of the offset cylinder 5 are located in accordance with FIG. 3 four plate cylinders 7, which are separated by color separation forms, which are rolled by colorful devices with 8 different colors. In addition, a humidifier 8 is again provided in each inking unit 8, which, when used in a wet offset form, moistens it.
    Color separation forms have carved reliefs, which are respectively rolled up and correspond to printed areas of a combined printing form determined by a specific ink, and transfers the multi-color image located next to each other in paints on the offset cylinder 5 that functions as a multi-colored collecting cylinder, which in turn rolls up the paint
    the printing plate on the plate cylinder 10. A multicolor image of this rolled paint of the assembly plate is transferred by means of a cylinder 34 for transferring the image to a sheet, which
    passes between the offset cylinder 3 and the cylinder 34 for transferring the image. The prefab printed form preferably consists of a high printing preprinted form, but may also consist of
    of a wet offset printing form, in which case this printing plate is wetted with a dampening apparatus, which, when viewed in the direction of rotation of the printing cylinder 10, is located
    at the back of the point of contact with the cylinder 34 for transferring the image and in front of the point of contact with the offset cylinder 5.
    In order to conveniently position the cylinder 34 for transferring images on the circumference of the offset cylinder 3, the offset cylinder 5 is disposed with some displacement relative to the offset cylinder 3 located opposite to the outside, i.e. in accordance with FIG. 3 slightly to the right. Due to this, on the circumference of the offset cylinder 5, to the right of its vertical midline, there is a place for the installation of four
    supporting color separations of the forme cylinders 7, so that the offset cylinder 5 in this embodiment example interacts in general with five forme cylinders.
    Based on this configuration, the feeding of the sheets to the blanket cylinder 3 is shifted somewhat up compared to the printing presses according to FIG. 1 and 2, and therefore the section of the circumference of the offset cylinder 3 between the transfer cylinder 2 and transfer cylinder 18, which the sheet passes through, is somewhat larger; in the example under consideration it is equal to half the circumference of the cylinder, however, if necessary, it could also be easily made slightly smaller. On the upper portion of the circumference of the offset cylinder 3, three forme cylinders are provided, namely, to the right of the vertical midline one forme cylinder 12 with its inking unit 13 in the rack 14 of the inking device and to the left of the vertical midline two formini cylinder 15 with its inking machines 16 rack 17 inking machine.
    Thus, the sheets, when the slot passes between the offset cylinder 3 and the cylinder 34 for transferring the image, receive on one side a three-color offset print and on the other side a four-color collection print. Therefore, in this way, non-counterfeit backgrounds can be produced on both sides of the banknotes in various printing methods, the offset printing method produces images with superimposed inks and the method of printing with several forms produces an image with inks next to each other.
    FIG. 4-6 show another embodiment of a printing press, in which an indirect printing press A is reversible and can occupy three different printing positions. The printing machine according to FIG. 4-6 has the same sheet feeding device 2, the same printing machine C for metallographic printing and basically also the constructed printing device A, as well as the already described printing machine according to FIG. 3. The same parts are marked with the same reference numerals.
    The differences are that the offset cylinder 5 can be interchanged between the position for offset printing (Figs. 5 and 6) and the position for printing from several forms (Fig. 4), that the cylinder 34 for transferring images can be interchanged between the working position, in which it adjoins both the blanket cylinder 8 and the plate cylinder 10 and the non-working position retracted from both of these cylinders, that the plate cylinder 10 can also be rearranged, has a matching inking device 11 and or an offset printing form (Fig. 5 and 6), or national team
    the printing plate (FIG. 4) and that, finally, the forme cylinders 7 that are in contact with the offset cylinder 5 have either offset printing plates (FIGS. 5 and 6) or color separation plates (FIG. 4).
    0 A sheet feeding system 33 with a stop bar of the same, as in the printing machine in accordance with FIG. 3. With the offset cylinder 5, in addition to the plate cylinder 10 with its inkstand device 11, the matrices 5 again match the formaid cylinders 7 with the inking machines 8, which are located to the right of the vertical centerline of the offset cylinder 5. The offset cylinder 3, as in the printing machine, in accordance with FIG. 3,
    0 is rolled up again with three offset plate plates 12 and 15.
    In the printing position with several forms in accordance with FIG. 4 offset cylinder 5, the cylinder 5 is retracted from the offset cylinder 3, the plate cylinder 10 carries a complete printing plate having a perfect printing pattern, is adjacent to the offset cylinder 5 and is separated from the associated cylinder
    With this inking device 11, which, for example, can be simply carried out by draining adjacent paint rollers or transfer rollers. The cylinder 34 for transferring images takes up a working position.
    5 Four forme cylinders 7 carry color separation plates. The printing position from several forms in accordance with FIG. 4 and the created image for printing from several forms exactly correspond to the configuration of the described press in accordance with FIG. 3 and the image obtained there for printing from several forms.
    In the position for offset printing in accordance with FIG. 5 the offset cylinder 5, as in the case with the printing press according to FIG. 1, pressed against the offset cylinder 3, the forme cylinder 10 bears the paint rolled up by the inking apparatus
    0 11 offset printing plate, adjacent to the offset cylinder 5 and rolls it with paint. Form cylinders 7 are also equipped with offset printing forms. The cylinder 34 for transferring images takes a non-working position in which it is retracted from both the printing cylinder 10 and the offset cylinder 3. In this case, the sheet passing through the printing cylinders 3 and 5 is equipped with a three-color offset print on the upper side
    and on the underside of a five-color offset print.
    FIG. 6 shows another offset printing position of printing press A, in which offset cylinders 3 and 5 are again pressed against each other, however, the forme cylinder 10 is retracted from the offset cylinder 5 and interacts with the cylinder 5 occupying the working position and the transfer cylinder 34 occupied by the working position images, which is pressed against the blanket cylinder 3. The plate cylinder 10 carries an offset printing plate rolled up by the paint by the inking device 11, the design of which is transferred by means of a cylinder 34 for transferring from expressions in the worksheet. Four plate cylinder 7 carry rolling paint offset cylinder 5 offset printing plates. Thus, the sheet first obtains a three-color offset print on the upper side of the printing slots between offset cylinders 3 and 5 and a four-color offset print on the lower side and then another single-color offset print on the bottom side using a cylinder 34 for transferring images.
    The invention is not limited to the exemplary embodiments described, but allows for a variety of options from the point of view of the number and arrangement of interacting with offset cylinders 3 and 5 of the forming cylinders, the construction of the cylinders of the sheet transporting device, as well as the design of the metallographic printing machine.
