In connection with the placement of the cutting device after the printing section in a known machine, there is an unjustified consumption of printing materials when printing products of a reduced format. The purpose of the invention is to reduce the use of printed materials. This goal is achieved by the fact that in a rotary printing machine for multi-color printing, containing a printing unit mounted on a frame, including a printing cylinder mounted on a frame-bracket, a mechanism for moving a frame-bracket in a horizontal plane in a direction transverse to the axis of the printing cylinder the ability to rotate on a frame mounted on parallel axes of the printing cylinder of the frame guides, offset and plate cylinders and means for applying paint and control fluid to the frame PVC cylinders, a device for continuous unwinding and feeding into the printing section of the material being processed, a rotary device for cutting the tape of the material being processed into sheets, a sheet receiving device and an actuator, a device for continuous unwinding and feeding into the printing section of the material being processed has a ribbon-leading friction roller pair and a rotating drive one of the elements of this pair, which includes a speed variator, and a rotary device for cutting the tape of the material being processed into sheets is placed between the friction with a roller pair and a printing cylinder, while the printing cylinder is installed with the possibility of simultaneous contact with all offset cylinders and has slider-controlled spring-loaded grips that are uniformly p-positioned around its circumference. In addition, the machine has TpaHcnopnoe means for moving the cut sheets to the printing cylinder with a speed exceeding the speed of movement of the grips of the printing cylinder. FIG. 1 is a schematic of a rotary multi-color printing press; in fig. 2 - the same part. The rotary printing press for multi-color printing contains the printing section mounted on the base 1, including a print cylinder 3 mounted on the bracket 2, a print cylinder 3, a mechanism for moving the frame brackets 2 in a horizontal plane transverse to the axis of the printing cylinder 3, including two pneumatic cylinders 4, rods 5 each of which are connected with rods 6, and levers 7 and 8 connected to rods 6 and pivotally connected by means of axles 9 and 10 with a bed 1 and by means of axes 11 and 12 with a stand 13 of a frame-bracket 2, pa rotatably mounted on parallel printing cylinder 3 guides 13 and 14 beds 1 frame 15 offset 1619 and formes 20-23 cylinders and means for applying ink 24 and moistening liquid 25 to forme cylinders 20-23 by means of cylinders 26, the device for continuous unwinding and feeding into the printing section of the material being processed 27 having a ribbon-rolling roller pair 28 and 29, the roller 28 of which has a rotary actuator in a switching speed variator 30, a rotary device for cutting the ribbon 27 into sheets, placed between riktsionnoy 2B to the roll pair 29 and the impression cylinder 3 and consisting of the drive 31 and the fixed blade nozha32, listopriemnoe device 33 and the drive. The machine also contains a vehicle for moving the cut sheets to the printing cylinder with a speed exceeding the speed of movement of the spring-loaded grips 34 fixed to the cylinder, consisting of a drive roller 35 and a roller 36 in contact with it. The printing cylinder 3 is installed with simultaneous interaction with all offset cylinders 16-19. The machine units are driven from a common drive shaft 38 connected to the engine 37. The drive roller 28 is rotated from a speed variator 30, the input gear of which is connected by means of a belt drive 39 and a tapered bevel gear 40 - 38. 28 from the variator is carried out through the belt transmission 41. By varying the speed of rotation of the roller 28, it is possible iz- The change in the format of the sheets to be cut, since the rotational speed of the power knife 31 is constant and, therefore, the length of the length of the tape 27 and the cutting device passing between the cutting moments can be equal. The axis of rotation of the cylinder 26, the mold 20 and the offset 16 cylinders of the lower printing unit are located in the same horizontal plane, while the respective cylinders in the other printing units are located in different planes. This allows the chat machine to be compact. In addition, with this arrangement of the cylinder, they can be rotated by the shaft shaft 42, which is rotated from the shaft 38 through a bevel gear 43, by means of a worm gear 44. Frame 15 Consists of two vertical walls 45 connected to the top 46 and two lower 47 and 48 crossbars, on which rollers 49 and 50 are fastened, which interact with guide rails .13 and 14 of frame 1. On crossbar 48, additional roller 51 is fixed to exclude removal of rollers 50 from guide rails 14; Frame-bracket 2 is mounted on guide rails 52 bed 1 and rests Rollers 54 are provided by the ROLLERS 53 to eliminate the displacement of the frame 2 along the axis of the printing cylinder 3. In the lower printing unit, bearings 54 and 55 of the form 20 and offset 16 cylinders are mounted with a possibility of movement between the horizontal guide bars 56 On the frame 15 between the bearings 54 and 55 springs 57 are located, pushing the bearings apart, when there is no compressive force. On the other hand, the adjustable stopper 58 is designed to adjust the degree of pressing of the plate cylinder 20 against the cylinder 26. L The stopper 58 has a spring 59, which, when the force is removed, allows the plate cylinder 20 and the cylinder 26 to be separated. In the remaining printing units, the bearings 55 are mounted with the possibility of longitudinal horizontal movement between the guide blades 56 and pressed to the printing cylinder 3 by the spring 60. Each forma cylinder 21 (22,23) is located slightly above the cylinder 26 and the offset cylinder 17 (18,19) and is mounted with the possibility of and between the guides 56 and 61, the latter of which one end is pivotally fastened to the frame 15 and biased by a spring 62 for the correct positioning of the cylinders 21-23. The upper printing units are also provided with adjustable stops 58. The machine is equipped with adjusting the degree of touch between the printing cylinder 3 and the offset cylinders 16-19, including an eccentric 63, which interacts with the column 64, which interacts with the bearing 55 of the offset cylinder 1 (17-19 ). The eccentric 63 is rigidly connected to the worm wheel 65, connected to the adjusting knob 66. The machine works as follows. Cardboard tape material 27 is fed into the machine from the bottom right. the latter, passes through the guide rollers 67 and 68 and enters the drive roller 28, which, interacting with the roller 29, feeds the material to the cutting device of the tape 27 on the sheets. The sheets cut from the tape by roller 35 and 36 are transported to the printing cylinder 3. Since the speed of movement of the sheets by rollers 35 and 36 is greater than the speed of movement of the slides 69 and 70 of the grippers 34, the sheets 35 and 36 are inserted into the open slides 69 of the grippers 34. as stated above, the format of the cut sheets is controlled by the speed of rotation of the roller 28 by means of a variometer 30. The sheets clamped by the grippers 34 are transported by the printing cylinder 3, which is driven into rotation through the gear train 71, through the interaction zones of the printing cylinder 3 sec. webbing cylinders 16-19 which form on the surface of the sheet-mnogokra juicy image. After passing the printing zones, the sheets are released by means of the slides 70 from the grippers 34, fall into the contact zone of the printing cylinder 3 and the roller 72, are ejected in the direction of the row of sheet transporting rollers 73 and the output. d ts last to the receiving sheet: the device. When the format of the printed sheets is changed, the frame-bracket 2 with the printing cylinder 3 is moved by means of pneumatic cylinders 4 to the left of the offset cylinders 16-19, freeing the latter from the printed contact. After that, frame 15 with form 4И 20-23 and offset 16-19 cylinders can be completely withdrawn from
    the printing machine along the guides 13 and 14 for changing the printing plates on the forme cylinders 20-23.
