    The invention relates to printing presses, in particular to a printing device of a rotary printing machine for duplex printing.
    The purpose of the invention is to improve the performance of the device.
    FIG. 1 shows the proposed printing device of a rotary printing machine for duplex printing; in fig. 2 — device for fastening the bottom tire and the form of the counter-pressure on the cylinder of the counter-pressure; in fig. 3 - bottom tire, cut; in fig. 4 - counterpressure shape, section.
    The printing device 1 of the rotary printing machine has two parallel-mounted printing units 2 and 3 duplex, each of which has an inking device 4, consisting of a roller 5 with a mesh surface and an inking apparatus 6. A roller 5 with a mesh surface of the printed node 2 interacts with the plate cylinder 7 and the counter-pressure cylinder 8 interacting with it, while the roller 5 interacts with the additional surface of the printing unit 3 with the additional plate cylinder 9 and with the with him

    cylinder 10 counterpressure. The paper web 11 fed to the printing device 1 is initially taken up with a chrome roller 12 and fed to the ea-eor between the forme cylinder
    7 and a backpressure cylinder 8, where the paper web 11 is printed on the front side. From the plate cylinder 7, the paper web 11 is guided by two chrome-plated guide rollers 13 and
    14 from the bottom to the second gap between the additional platen cylinder 9 and the supplemental cylinder 10 of the counterpressure, where it is subjected to printing a revolution. The cylinders 8 and 10 of the counterpressure have a circumference parallel to the axis of the recess 15 and the fixture 16 for fastening the printing plate (tire) 17 and the substrate 18 and the corresponding recess-15, made in the form of three tensioning shafts 19-21 installed next to each other, lengths which corresponds approximately to the length of the recess 15. Both external tension shafts 19 and 21 serve to tension the substrate 18 and have a longitudinal chamber 22 for receiving both ends 23 and 24 of the substrate 18. The middle tension shaft 20 has two longitudinal diametrically opposed each other 25 and 26 for placing the ends 27 and 28 of the tire 17. The substrate 18 consists of an elastic material, preferably cork, flax or rubber or textile fabric, depending on the size of the available words. The thickness of the substrate 18 depends on the thickness of the tire 17, so that the total thickness of the substrate 18 and the tire 17 does not exceed a predetermined value, for example, 3.3 mm. The ends 23 and 24 of the substrate 18 are folded back and sewn to the substrate 18 so that at the ends 23 and 24 of the substrate 18 a loop 29 is formed to receive the retaining wire 30. The substrate 18 is reinforced in the area surrounding the cylinders 8 and 10 of the counter-pressure so that there is a greater thickness , than at the ends 23 and 24 of the substrate 18. The tire material 17 or at least its surface depends on what requirements are imposed on the surface 31 of the cylinders
    8 and back pressure, i.e. The material may be solid, soft, red or water repellent, oleophilic or hydrophilic.

    If the plate cylinders 7 and 9 are provided with a solid printing plate (with a hardness of about 90 in shore D), then an optional It is useful to use soft cylinders 8 and 10 of counterpressure, or a soft surface on them. In this case, you can use the well-known rubber panels, equipped with pearls, caused by vulcanization. However, if the plate cylinders 7 and 9 are provided with a soft printing plate (with a hardness of about 60 Shore D), then the surface of the cylinder 8, 10 must be counter-pressured with a solid and paint-repellent, as required when printing using water-based paints. In such a case, the tire 17, for example, trimetallic, is tensioned over the substrate 18 on the cylinders 8 and 10 of the counter-pressure. The trimetallic tire 17 has a thickness of about 0.3 mm and an outer layer, for example, of steel, copper and chromium. The tire 17 may also be plastic or nylon. In order to facilitate the tensioning process, elastic fabric (for example, from flax) is attached to the both ends of the tire 17 at the location 32 and, moreover, the ends are provided with clamping pads 33 and 34. The length of the tire 17 is chosen so that the riveted positions 32 do not fit the circumference backpressure cylinders, and entering the recess. ku 15.
    The device works as follows.
    In order to supply the cylinders 8 and 10 with the form of the counterpressure, the loops 29 of the lower tire 18 with the retaining wires 30 are inserted into the longitudinal grooves 22, after which they are tensioned by rotating the tension shafts 19 and 21 and fixed in this position. The first clamping block 33 of the tire 17 is inserted into the first upward groove 25 of the tension shaft 20, after which it is rotated halfway in the direction or counterclockwise until the opposite groove 26 is pointing upwards. The second clamping block 34 of the tire 17 is inserted into the groove 26. By further rotating the tension shaft 20 in the direction or counterclockwise, the ends 27 and 28 of the backpressure printing plate are lengthened, as a result of which the tire 17 is pulled onto the back pressure cylinders 8 and 10. The tension shaft 20 is fixed in a tensioned position. Both of the printed circuit assemblies 2 and 3 can also be installed one above the other.
