    The invention relates to papermaking machines, namely, to press mechanical devices for squeezing water from multi-layer paper webs. . A press mechanical device for extracting water from a multi-ply paper web is known, comprising a combination of a plurality of press rolls forming successive press presses grips, forward looping cloths for transporting the web through the press presses, the first of which is formed by the first press shaft with a suction chamber passing from the first to the second pressing grip, and the second pressing shaft, covered by the pressing loopbacks, contacting in the area of the first gripping, the second pressing The first gripper is formed by the first and third pressing rolls, the third pressing gripper is formed by the third and fourth pressing rollers, and the fourth pressing gripper is formed by the fifth covered by the third pressing loop cloth and the sixth pressing roller 1 J. However, when the paper web is dehydrated, the connection between the layer mi, as a result of the dehydration process is ineffective. The purpose of the invention is to increase the efficiency of dehydration without disrupting the bond between the layers. The goal is achieved by the fact that in a press mechanical device for pressing water from a multi-layered paper web containing a combination of a plurality of press rolls forming successive press presses, press loop loops for transporting the web through press presses, first of which is formed by the first press shaft with a suction chamber extending from the first to the second pressing nip, and a second pressing shaft, covered by the pressing loop cloths in contact between the second grip is formed by the first and the third pressing rolls, the third pressing grip is formed by the third and fourth pressing shafts and the fourth pressing grip is formed by the fifth covered by the third pressing loop and the sixth pressing shaft, the third pressing shaft has a suction chamber extending from the second to the third pressing point. cotton wool, and the fourth and sixth press rolls have a fourth press loop cloth covering them, the first and third press cloths contact in the second grip zone, and the third and fourth press cloths contact in the third and fourth grips and all the way between the third and fourth zones. fourth grabs. Moreover, the surface of the sixth forging shaft is made grooved. In addition, the device has a seventh pressing shaft, which forms a fifth pressing grip with the sixth pressing shaft. The drawing shows the proposed device, a General view. The press mechanical device for extracting water from the multi-layered paper web 1 coming from the forming machine comprises press shafts 2-8, forming successively located press claws 9-13 between them. The first gripper 9 is formed by the first pressing shaft 2 and the aspirantine chamber 14 and the second pressing roller 3. The suction chamber 14 extends from the first 9 to the second 10 pressing gripper. Press shaft 2 is covered with loopback cloth 15, and press shaft 3 is covered with loop cloth 16. Loop cloths 15 and 16 are in contact with each other in the area of the first gripper 9. The canvas is first dehydrated through the bottom surface - in the first clamp 9, and then the other, the upper surface of the canvas Subjected to atmospheric air, the suction chamber 14 sucks water in the direction of the lower surface of the web. The second press nip 10 is formed by the first and third press shafts 2 and 4. In the second press nip 10, the flow of water is reversed and water is sucked through the upper surface of the web by the suction chamber 17 of the shaft 4 passing from the second 10 to the third 11 press nip. The third press seizure 11 is formed by the third and fourth press shafts 4 and 5, the fourth press seam; 12th and 6th grab presses
