    This invention relates to printing. The purpose of the invention is the expansion of technological capabilities through simultaneous duplex printing by various methods. The machine can print on both sides of the paper an image of matched colors through a letterpress printing form, on which the ink is applied by a collecting cylinder, which in turn receives ink from stencil rollers, the number of which corresponds to the number of colors, or the image from the overlayed colors and patterns by means of form cylinders replacing the color separation cylinders and supplied with printing plates which put paint on the corresponding offset cylinder, and their number corresponds to the number of images and images of each of the types mentioned. The machine contains two offset cylinders, acting or as collecting cylinders, spaced from each other, and each of them is in contact with a cylinder carrying the aforementioned letterpress form, the image from which is transferred through another offset cylinder to paper, or as offset cylinders, pressed together and printing on paper, or one as a collecting cylinder, and the other as an offset cylinder, both of which are distant from each other. In the latter case, the image on the offset cylinder is transferred by the image transfer cylinder, which replaces the forme cylinder, to the said offset cylinder. 8 il.

    The rotary multi-color printing machine for printing on roll or sheet paper contains an intaglio printing cylinder 1, an intaglio printing cylinder 2 with rubber coating, a second rubber-coated cylinder 3, in contact with a printing press 1 of high printing, and the third cylinder 4 having a rubber coating, in contact with the first cylinder 2 mold or stencil rollers 5, interacting with them colorful devices 6, and the forme cylinder 1 letterpress and second cylinder etc. 3 have inlet and outlet means relative to correspond - the first 2 and the third four TS1SHPNDROV. The machine is equipped with a cylinder 7, which is in contact with the perry center 2, a TI-.IM cylinder, 7 repins, 1 m tium, interacting with it through a single-sided form or tr; 1 screen-H1, 1 rolls 8, and an additional high-grade printing plate 9 in contact with the third 4 and fourth 7 cylinders, while the first 2 and fourth 7 cylinders have means for supplying and discharging one relative to the other in the form of eccentrics 10, 11. The additional high printing cylinder 9 has means for supplying and discharging (not shown) relative to the fourth cylinder 7.
    The device performs the operation as follows.
    The machine of FIG. 1 to 4 is a roll-type printing press: and contains two input rollers 12 for a paper tape 13 and a device 14 for removing dust and eliminating static electricity. Printing on paper 13 can occur both between two cylinders 3, 4 according to the Eagles-Eagles method (Fig. 1), according to the offset-Eagles method (Fig. 3) or according to the Eagles-Offset method (Fig. 4), and between two most of which interact with shi (offset) cylinders 2.7 through cylinder 4 the other half of the offset-offset method (Fig. 2). After printing, the paper is transported by the exit rollers 15 from the machine.
    The rotational directions of the cylinder are arrows.
    When printing according to method 5, Eagles (offset) Cylinder are spaced apart (figs like cylinders 3, 4 are pressed.) In practice, it is very easy to remove chi by means of ex 10.11, on which each (offset) qi is mounted. 7. Installation on eccentrics for adjustment and for none of the cylinders in an idle machine; it is performed so that the eccentric of the lindra is moved with rotation, when the cylinders are separated by a min, a distance of just millimeters (by fi the distance is increased).
    The printing machine consists of symmetrical halves, the poet is given a detailed description of the right half of the Noah.
    In the measure (offset) shown in FIG. 2, the cylinder 2 operates with four stencils, on which there is an engraved according to the zones printed in the corresponding color using the matching applied by means of the apparatus 6 with a double cr tank. It is also desirable to roll the rollers 5 with the relief of this material, which is not subjected to formation even with the relief of the relief, which allows the floor to have thin lines that form the background.

    which interacts with cylinder 4 of the other half
    The direction of rotation of the cylinders is shown by arrows.
    When printing by the method of Eagles - Eagles (offset) Cylinders 2, 7 are separated from each other (figure 1), while the cylinders 3, 4 are pressed to each other. In practice, it is very easy to remove the cylinders by means of eccentrics 10,11, on which the housing of each (offset) cylinder 2, 7 is mounted. The installation on eccentrics is used for adjusting and for pushing the cylinders out of working condition of the machine; it is designed in such a way that with rotation of the eccentric the axis of the cylinder moves. During cylinder lead, they are separated by a minimum distance of only 1 or several millimeters (in Fig. 1, this distance is increased).
    The printing machine consists of two symmetrical halves, therefore, a detailed description of only one, the right half is given below.
    In the embodiment shown in FIG. In example 1 (offset) cylinder 2 interacts with four stencil rollers, on which there is a relief 16, engraved according to the contours of the zones, printed in the corresponding color using the appropriate ink applied by the inking machine 6 with a double ink reservoir. It is desirable to produce rollers 5 with relief 16 of solid material that is not deformed, even with very thin relief, which allows for very thin lines that form a protective background. The four-color zones are transferred onto (offset) cylinder 2, acting as a collecting cylinder, on which the zones are combined and from where they are transferred onto a single plate cylinder 1 carrying a typographical printing plate 17 in contact with the collecting dial 2 plate 17 is a complete printable pattern in four colors. In turn, the full four-color image is transferred to (offset) cylinder 3, the diameter of which is smaller than the diameter (offset) of cylinder 2, and

    At the same time, another image is printed on the other side of the paper 13 by the offset cylinder 4, which is created similarly by the corresponding organs of the other half of the machine, namely, four additional stencil rollers 8, containing a relief plate 18, coated with paint using four inks 19, a collecting cylinder formed another (offset) cylinder 7 and a plate cylinder 9 in contact with it and provided with a printing plate 20 representing a full pattern of the second image, Available for offset offset 4. During the simultaneous printing, offset cylinders 3 and 4 mutually serve as backpressure cylinders.
    In the case of using the same offset printing machine (Fig. 2), it is enough to replace rollers 5 and 8 with forme cylinders 21, 22, equipped with printing plates 23 and 24, fold 1 offset cylinders 3 and 4 away from each other. Forming cylinders 1 and 9 are from offset cylinder 2 and 7 respectively and pressing cylinders 2 and 7 against each other so that they are printed on paper 1. Cylinders 3,1,4 and 9 do not work and are not set in motion, since their drive system is not connected to the drive unit of the machine.
    The printing plates 23 and 24 are offset printing plates used in the dry office.
    Seth; they show private drawings on which the paint is applied from the ink devices 6 and 19. Such private drawings of various colors are combined on the offset cylinder 2 and 7 respectively, which act as collecting cylinders for the private drawings forming the multi-color image. The result is a four-color dry offset print on each side of the paper for its passage between the cylinders 2.7.
    Adjusting the distance between different cylinders, namely offset cylinders 3 and 4, as well as between offset cylinders 2 and 7 and between the plate cylinder 1 and 9, respectively, and the offset cylinder 2 and respectively 7, as well as other needs

    The movements of other shafts and cylinders relative to movable cylinders are carried out in a known manner, in particular by installing halls and cylinders on eccentrics, as mentioned in connection with offset cylinders 2 and 7. The removal of cylinders takes a very short distance, of the order of several millimeters. Colorful devices 6 and 19 are mounted on movable carriages. In accordance with FIG. 3 on the machine, you can also print by the method of offset, - Orlov. In this case, the position of the working bodies corresponds to the position in the Orlov – Orlov method according to FIG. one.
    In this example, the right side of the machine prints according to the Eagles method by means of stencil rollers 5 with relief 18 and a plate cylinder 1, which carries the printing press 17, on which the ink is applied by the offset cylinder 6, which acts as a collective cylinder, where the ink enters with stencil X rollers 3 with relief of Kt.
    The left side of the machine performs offset printing by means of plate cylinders 22 provided with offset plates 24, and the paint is applied by the offset cylinder 7. In this case, the image is transferred from the offset cylinder 7 by means of the image transfer cylinder 25 to the offset cylinder 4, the image transfer cylinder 25 replaces here plate cylinder 9 (Fig. 1) and performed using a rubber cylinder or lined cylinder. In this case, the mixed printing offset image is printed on the paper by means of the offset cylinder 4 after being transferred through the cylinder 2.
    In the fourth use case (Fig. 4), the two halves of the machine print the Eagles - offset. The left side prints the image according to the Orlov method by means of rollers 8 with a relief plate 18 and a plate cylinder 9 carrying a printing plate 20, and the right side prints a offset image by means of plate offset cylinders 21 with plates 22 and an image transfer cylinder 26 replacing the plate cylinder 1.
    It is possible that the choice of the sides at the same time of the mixed printing is important if the paper printed in the described machine passes into another printing unit to receive at least one side of the second image, for example, a metallographic print as the main pattern .
    Figures 5-8 show various arrangements of organs in a sheet press for printing according to the Eagles-Eagles method (Fig. 5), offset-offset (Fig. 6); offset - Orlov (Fig. 7) and Orlov - offset (Fig. 8). Such a machine and its variants are almost identical with the roll machine of FIG. 1,2,3 and 4 except for only the means of transporting sheets of paper 27. FIG. 5-8 trajectory of sheets 27 is shown in solid line. The printed paper sheets 27 are fed in a known manner by means of a feed cylinder 28 and two transfer cylinders 29 provided with grippers. Unlike paper tape 13, sheets 27, in any embodiment, are always contacted with /, from the offset cylinders of pairs,, h and one of the offset and ornd pairs 2.7, and in this example with offset cylinders) 1dry 3 and 2, also acting as transfer cylinders and equipped with grippers. For transferring sheets from the cylinder 3 to the cylinder 2, an intermediate transfer is provided, the cylinder 30, also equipped with grippers and constantly interacting with two offset cylinders 3 and 2. After printing is finished, sheets 27 of the protractor are equipped with a chain gripper system 31 to the exit foot or to another machine to complete printing, such as for metallography.
    When printing is carried out according to the Orlov-Orlov method (FIG. 5), the arrangement of the elements corresponds to the arrangement shown in FIG. 1. Two offset cylinders 2 and 7 are spaced apart and act as collecting cylinders on which paint is applied by rollers 5 with relief plates 8 a and B with plates 18 and which in turn transfer paint to form 1) high-pressure printing and respectively 20 on the plate cylinder 1 and respectively 9.

    The devices 6 and 19 are shown schematically with several shafts and contain the same elements as in FIG. 1-4. The offset cylinders press together and print corresponding images on both sides of the sheets 27.
    In this example, the ratio of the diameters of the cylinders 3, 1,5,4,9,8 and 30 on the one hand and cylinders 2 and 7 on the other hand is 1: 3; the periphery of cylinders 2 and 7 corresponds to three sheets of paper, each offset cylinder 2.7 carries three panels, while cylinders 3 and A carry only one.
    The fact that the sheets 27 are in contact with that area of the offset cylinder 2, on which there remains a little paint that is not transferred to the plate cylinder 1, practically does not have a negative impact, since the structure is designed in such a way that the colorful zones on the cylinder 2 that are in contact with sheet 27, bearing the image printed by cylinder 3, consistent with the color zones of the printed image (3.
    To comply with the registration conditions, it is necessary to position the corresponding cylinders as follows: the sum of the arc length around the periphery of cylinder 1 in the direction of rotation of the cylinders between the points of contact of the latter with cylinder 2 R with cylinder 3 plus the length of the arc around the periphery of cylinder 3 between points of contact of the latter with cylinder 1 and the point of entry paper per cylinder 3 plus the length of the paper path between the point at which it enters cylinder 3, plus the length of the paper path between the point at which it enters cylinder 3, before the point of entry for cylinder 2 should and to be equal to the arc length on the periphery of the cylinder 2 between the last point of contact with the cylinders 1 and 30 plus the length of the periphery of the cylinder 1 (which is 1/3 of the circumference of the cylinder 2). Under these conditions, a certain point of the image transferred onto the paper from the cylinder 3 and coming from one of the three panels mounted on the cylinder 2 coincides when the paper enters the cylinder 2 with the same place of the image of the subsequent panel. The design of the cylinders for achieving such a register is known. In addition, since the sheets 27 are not subjected to pressures
    at tststindre, the possible transfer of paint from cylinder 2 to the sheets is very incomprehensible.
    To implement the offset-offset printing method (FIG. 6), the arrangement corresponding to the one shown in FIG. 2. Both offset cylinders are pressed against each other and paint is applied on them from offset plates 23 and 24 mounted on the form cylinders 21 and 24. The offset cylinders 3 and 4 are separated from each other, the form cylinder 1 is removed from the offset cylinders 3 and 2 and the plate cylinder 9 is removed from the offset cylinder 7. The plate plates 1 and 9 are idle as the offset cylinder 4, while the other offset cylinder 3 serves as a transfer cylinder for sheets transported along the transfer cylinder 30 to the offset cylinder 2 for print on both cylinders 2 and 7.
    For the implementation of the mixed offset printing method - Orlov (Fig. 7), the arrangement of pa6o4V {x organs corresponds to the arrangement shown in Fig. five.
    In this example, the right side of the machine prints the Eagles by means of stencil rollers 5 and a plate cylinder 1 bearing a letterpress form 17, where ink comes from the offset cylinder 2, in turn, the collecting cylinder, where the ink comes from the rollers 5.
    Left side of the machine It provides offset printing by means of plate cylinders 22 provided with plates 24, from which ink enters the offset cylinder 7. In this case, the image is skewed from the offset cylinder 7 by means of the image transfer cylinder 25 to the offset cylinder 4; the image transfer cylinder 25 replaces in this case the plate cylinder 9. It is made, with the aid of a rubberized or offset cylinder. So, the offset printing of the print 15ts on paper by offset cylinder 4 after transfer through cylinder 25 is simultaneous offset printing. With regard to the contact between sheets 27 and offset cylinder 2 transporting them to the chained chain system, In connection with FIG. five.

    In the fourth embodiment, the implementation (Fig. 8) for printing according to the Eagles method - the offset of the half of the machine is changed by functions, and the left side prints the image of the Eagles by means of stencil rollers 8 with plates 18, the image transfer cylinder 25 is replaced by the form cylinder 9 provided with a high shape 20 printing, representing the full pattern, and the right half prints the offset image by means of the plate cylinder 21 with plates 23, while the plate cylinder 1 of the previous example is replaced by the cylinder 26 of the image transfer.
    In all examples, rollers 5 and B, intended for applying paint to collecting offset cylinders 2.7, can be replaced with partitioned plates acting as color separation plates for paints applied to the cylinder. In this case, it suffices to replace the plates 5.8 on the cylinders that are in contact with the corresponding offset cylinder, in order to change from one printing method to another, whereas the cylinder bodies do not change. When modifying one of the cylinders 1 or 9 into the image transfer cylinder 26 and 25, the body of this cylinder may remain unchanged if the printing plate is thin enough and can be replaced with a web and vice versa.
    At least one of the printing units with the printing roller 5 or 8 and with the inking device 6 and / or 19 on one or the other side of the machine can be a wet offset printing unit, and the corresponding printing cylinder or cylinders in this case are supplied with a wet printing plate. offset printing.
