    An offset printing machine comprises a plate cylinder and a blanket cylinder respectively carrying roller tracks rolling on one another and determining the center distance between the two cylinders. At least one inking roller with a supple peripheral layer, fed with ink from an inking assembly, is carried by levers pivoted about the axis of an inking cylinder and it carries roller tracks in contact with those of the plate cylinder. The shaft of the inking roller is mounted in its roller tracks via eccentric hubs locked on the shaft and pivoting in the roller tracks via bearings, and one end of this shaft is fast with a gear coupled to a control shaft for adjusting the pressure contact of the inking roller upon the plate cylinder.

    FIELD OF THE INVENTION The invention relates to printing industry, in particular to rotary offset printing machines.
    A known rotary offset printing machine, containing form and offset cylinders with one rolling element in contact, roll cylinders, an ink tank and at least one rolling roller with an elastic coating, which has means for adjusting its pressure to the plate cylinder, including eccentric sleeves. and the rolling element in contact with the rolling element of the plate cylinder and mounted on brackets pivotally connected to the corresponding shaft of the rolling cylinder-i
    ra u.
    A disadvantage of the known device is the difficulty of adjusting the force of pressing the rolling paint roller to the printing cylinder.
    The purpose of the invention is to simplify the adjustment of the force of pressing the rolling paint roller to the plate cylinder.
    This goal is achieved by the fact that in the rotational offset printing
    a machine containing printing plate and offset cylinders with rolling elements in contact with one another, roll cylinders, an ink tank and at least one rolling paint roller with an elastic coating, having means for adjusting its pressure to the plate cylinder, including eccentric sleeves and rolling element in contact with the rolling element of the plate cylinder and mounted on brackets pivotally connected to the corresponding shaft of the rolling cylinder, means for adjusting the rolling pressure th inking roller to the plate cylinder comprises a drive shaft coupled through a gear to a shaft with profile inking roller, wherein the eccentric sleeve mounted on the shaft bearings pdsredstvom with profile inking roller.
    In addition, each eccentric bushing is installed with the possibility of angular adjustment relative to the axis of the rolling paint roller and fixing the position by means of a screw.

This is: shaft 14 with both ITS; 5K conch, mounted on two brackets 6 ro-harnessed: a rolling roller 6 comes. 6. Each bracket 8 can be moved to the outside of the € 5 € 5 of the bottom surface of the rolled frame E and the inside of which is installed the end of the roll E of the roll cylinder 4. Part of the bracket 8 , image; -o: tsa sleeve, i.e. a surrounding do-17, rigidly coupled to a coaxial gear 29, located in foreplay; with another gear 11, rigidly mounted on the pre-transfer drive shaft 30, mounted on the frame for rotation. As a result of the rotation of the drive shaft 30, droioho
    The bracket 8 rotates around the axis of the knurled cylinder 4 and the corresponding displaced of the knurled Kpaco -;: - ioro roller 6 in the direction of the plate cylinder 2 or in the opposite direction so that it is possible to change the print format.
    The roller 14 of the inking ink roller 6 is fixed in the loops 8 by means of bearings 31 mounted in slots provided in these brackets 8, and the position of these bearings can be adjusted by means of screws 32. These screws, which rest on the outer surfaces of the bearings 31, allow move these heads in the direction of the axis of rotation of the brackets 8, i.e. in. lev: le -: i of the rolling cylinder 4. Thus, they make it possible to regulate the pressing force of the rolling paint roller 6 in the rolling qi; n-1 4, i.e. adjust the compression of the elastic coating 27 upon contact with the colorful table and the degree of contact at that location.
    In the position of the stop, the rolling paint roller 6 is also in contact with the forme cylinder 2, against which it is pressed with greater or lesser effort, resulting in a more or less strong compression of the elastic coating 27. This compression arc is usually constant, and its length depending on the case, it can vary from 3 to 5 mm. Form cylinder 2, rigidly mounted on a horizontal-transverse shaft 33, mounted for rotation
    in bearings 34 mounted on sta1
    23, and has rolling surface 35, which consists of rings mounted on the end surfaces of the mold cylinder 2. These rolling surfaces 35 are in turn in contact with similar rolling surfaces 36 mounted on an offset cylinder 3, so as to ensure a constant center distance between the form 2 and offset 3 cylinders.
    In order to provide a constant clamping force for the knurling roller b to the mold cylinder 2 on the knurling paint roller 6, there are also rolling surfaces 37 located in a co-mix with rolling surfaces 35 of the forming cylinder 2.
    Each rolling surface 37 is mounted by means of a bearing 15 on an eccentric sleeve 7 fixed on the roller 14 of the knurling paint roller 6. Each sleeve 7 has a slot and is mounted on the shaft 14 by means of a clamping screw 16. Thus, it is possible to individually adjust the angular position
    each of the two bushings / relative to the axis of the knurling roller 6 so as to align the front and rear portions of the eccentric bushings 7 and, therefore, the rolling surface 37. Each of the sleeves 7 has a cylindrical neck 38 located eccentrically with respect to the axis of the shaft 14, with the bearing 15 fixed to the neck with a rolling surface 37. Each eccentric bushing 7 is sandwiched between under: a bobbin 28 of the knurling paint roller 6, abutting the protrusion of the shaft 14 on one side and an annular gasket 39 located between the bushing 7 and the bearing 31 fixed on the bracket 8 on the other side.
    The clamping of the knurling roller b to the plate cylinder 2 is provided as a result of which it rotates ;; two brackets 8 around the axis of the cylinder 4, while skimming 14B of the shaft B, with two eccentric bushings 7, refers to the approximation or removal of the rolling surface 28 relative to the price; to: the rolling surfaces 35 of the cylinder 2, those. the change in the force pressing the rolling paint b to the plate cylinder 2.
    The rotation of the roll 14 of the knurling roller is controlled with a horizontal-transverse shaft 10 mounted rotatably in the front part of the stand: -: b. 23 printed macheins. This drive unit is rigidly connected to gear 40, which transmits the rotary movement to gear 12, mounted 11; which can be rotated on the under; spike; 1 - to 17 of the cylinder 4. This toothed gear 12 is, in turn, meshed with another gear 13, rigidly seated on the front end of the shaft 14 of the rolling paint roller b.
    From this it follows that the rotation of the drive shaft 10 causes the rotation of the gear train 13 and, therefore, of the shaft 14 and the two bushings 7 mounted on it, resulting in a change in the center distance between the rolling roller b and the forme cylinder 2.
    The shaft 10 of the pressing force adjustment device is at one end connected to the sleeve 19, on which is mounted a disk 20 with a scale graduated in accordance with the size of the print format, and a foot 41 for blocking rotation of the shaft 10. On the sleeve 19 is rotatably mounted a second disk 21 , on the front surface of which there is a mark 42. The disk 21 can freely rotate on the axis of the shaft 10, but can also be locked in any desired position on a vertical plate 43 rigidly connected to the frame
