    The invention relates to the printing industry, in particular to the ink machines of rotary offset machines.
    The purpose of the invention is to reduce energy consumption.
    The drawing shows a colorful .apparatus rotary offset machines.
    Ink device contains installed on the basis of (not specified) the ink spray device 1, inter. a rasterized krasnoobredeyushchy cylinder 2, a plate cylinder 3 with an offset form 4, at least one rolling roller 5, which interacts with a rasterized color, a transfer ring 2 and a form 3 cylinder, operating with it; interaction with the plate cylinder 3 and a device installed with the possibility of interaction with the cylinder 2 to prevent the penetration of the moistening liquid into the printing ink, made in the form of at least one rubberized roller 7 and interacting with it, a separating roller 8 with a hydrophilic surface mounted between the last rolling roller 5 and the ink supply device I in the direction of rotation of the rasterized paint transfer cylinder 2 (in the direction of the arrow).
    The inking machine works as follows.

    about
    Using the inkjet sub device 1, the cells of the rasterization paint-transmission cylinder 2 are filled with printing ink. After two rolling rollers 5, the paint is rolled onto the printing plate 4 on the plate cylinder 3. By means of a wetting device 6, which can be performed, for example, in the form of a brush humidifier, the liquid is fed to the printing plate 4. The paint rolls onto the rubber sheet 9 of the offset cylinder 10. Between the offset cylinder 11 and the further non-depicted counter-pressure cylinder, printing of the paper web 12 is carried out. Through the rolling rollers 5 the moistening liquid flows from the printing form 4 to the ink-feeding cylinder 2 and from there - in fresh printing ink in the chamber 13 of the spray device 1
    In order to remove the moistening liquid from the printing ink in the cells of the ink-transfer cylinder 2 after contact with the last rolling roller 5, at least one rubber roller 7 interacting with the spray paint cylinder is installed in the direction of rotation of the rasterized paint-transfer cylinder 2 with which the separating roller 8 interacts with a hydrophilic surface. In this case, the rubber roller 7 is in a contact that is made by pressing against the side surface of the ratized ink-transfer cylinder 2, and the separation roller 8 is in a contact made by pressure from the side surface of the rubber roller 7.
    The paint transfer cylinder 2, the rubber roller 7 and the separation roller 8 are made with the same rotational speed, the driving gears of the rollers 7 and 8 being engaged with the driving gear

    The diameter of the rubber roller 7 is chosen so that, at the highest working speed, not a single drop of paint or a single drop of water comes off the side surface of cylinder 2 due to centrifugal force. However, the diameter of the separating roller 8 is selected so that at the lowest printing speed, a centrifugal force is already achieved, allowing exceptional removal of 8 water droplets from the side surface of the separating roller 8. At the same time, water droplets converging from the side surface are caught in the chamber 14 surrounding the rollers 7 and 8, from which they are diverted. The separation roller 8 may have a polygonal cross section. The edges of the polygon enhance the effect of separating the water droplets from the side surface of the separation roller 8.
    The device does not require the availability of means for heating the rasterized paint-transfer cylinder of means for cooling the plate cylinder and the pneumo-saddle, which ensures a reduction in energy consumption.

    Invention Formula
    An inking machine of a rotary offset machine containing a screen-mounted device installed on the base, a rasterized paint-transfer cylinder that interacts with it, a form cylinder with an offset form, at least one roll-on roller that interacts with a rasterized paint-spreading and form cylinder, a humidifying device that is installed interaction with the plate cylinder, and a device for preventing the penetration of the moistening liquid into the printing ink, Interaction of a rastriro- bathrooms kraskoperedayuschim cylinder, characterized in that, in order to reduce power consumption, the mouth
    In order to prevent the moistening liquid from penetrating into the printing ink, at least one rubber roller and a separating roller associated with it with a hydrophilic surface are installed between the last roll and the ink supply device in the direction of rotation of the rasterized paint transfer cylinder.
    lindra 2. It goes without saying that rollers 7 and 8 can be driven by friction from the rasterized paint-transfer cylinder 2, the diameters of the rubber roller 7 and the separating roller 8 are only a fraction, for example 1/10 of the cylinder diameter
