    A flat structure permeable to liquid, especially to a press felt for use in a papermaking machine, the structure being made up for a body (1) made of a castable polymer, the body having holes (2) formed during the casting process and possibly cavities (6), the diameter of the holes increasing substantially progressively from one surface to the other in such a way that the web-side surface is microporous and the other surface has pores substantially more open. The invention also relates to a method for the manufacture of such a structure.

    The invention relates to squeezing felt or squeezing grid cloth for removing liquid from a wybrous material and is intended for use in the pulp industry of the yog paper industry in the press section of a buoying machine.
    The purpose of the invention is to increase the drying capacity of the fabrics by ensuring their mechanical strength and uniform distribution of pressure.
    Fig 1 shows the felt (canvas), a longitudinal section; Fig 2 "- the same, top view; on figsZ - the same, longitudinal section; on "- the same, longitudinal section, option; Fig 5 is the same, longitudinal section, option; in Fig „6" - the device that is used. It is used to make felt (in a lot) longitudinal section0
    The canvas is made of cast lime and is indicated by the position 1 It is made mainly of ypeta - new rubber. In the cloth 1 there are conical holes 2 Surface 3 on the side of the web (and 2) are microporous and very smooth. The other surface has pores of a much larger size. Thanks to such a structure, when used as a crimping felt or a crimping net, there are good wear rates - driving properties, and the holes 2 are almost not clogged.
    A fabric similar to Fig. 1 is presented on the FSC, except that it is reinforced with reinforcing material "- material 4. Different synthetic fibers, threads, pieces of cloth, glass" - fiber, metal fiber, mesh can be used as feasting materials.
    Figure 4 presents the canvas
    1, except that it has pores in it 5. Pores can be open or closed with, open pores make the structure more
    spongy, improving dehydrating durability and uniform
    properties. Closed pores in the part where they are located improve the elasticity of the structure.
    Fig. 5 shows a web similar to Fig. 4, except that there are cavities 6 in it, which connect the holes with each other, Tacs of the cavity enter the opening of "TIAO

    the pressure distribution of the press endless flat belt presents a casting with the casting process performed, and the reinforcement material is placed into the casting.

    Belt form 7 is tensioned between two rolls 9, the surface of the form has conical spikes 8, the shape of which “- ryh corresponds to the shape of the holes in the structure. Raw materials in the form of polymers are applied to mattes, obtaining a structure of a given thickness. The starting material can be applied by casting, spreading or spraying. For final vulcanization of the material, it is usually heat treated.

    If it is required to reinforce the structure, a raw material, the starting material is layered, and the reinforcing material is placed between the layers.
    If it is necessary to increase the porosity of the structure, then appropriate substances, such as volatile compounds or water-soluble compounds, are added to the polymeric material in the process of "- preparation; these substances form pores in the structure under the action of heat or water. As one example of such water-soluble substances, ordinary salt can be given, the grain sizes of which determine the measures of pores

    formula of invention
    1 o Squeezing felt or squeezing mesh cloth to remove liquid - bone from fibrous material in the press section of a papermaking machine, containing a polymer base with reinforcing material, made in the form of an endless flat belt having vertical holes gradually increasing in diameter - re from micropores on the side of the surface intended to be received in the "- loamy material, up to a diameter greater than the diameter of the micropores, which is characterized by the fact that, in order to increase the dehydrating capacity, and its mechanical 5
    pressing pressure distribution, the endless flat belt is a casting with molded holes formed during the casting process, with the reinforcing material placed into the casting.
    2 "Felt or canvas according to claim 1, in which the endless flat belt contains cavities in it to equalize the internal pressure, passing through it in width and length, with some of the cavities interconnected at least with corresponding holes in the hole by intersecting them.

    Claims (3)
    [1]
    Claim
    1. A squeezing felt or squeezing mesh web to remove liquid from the fibrous material in the press section of the paper machine, containing a polymer base with reinforcing material, made in the form of an endless flat belt having vertical holes that gradually increase in diameter from the micropores from the surface side, intended for receiving yolokolny material, up to a diameter exceeding the diameter of the micropores, characterized in that, in order to increase the dehydrating ability by ensuring its m mechanical strength and uniform compression pressure distribution, an endless flat belt is a casting made in low tide shaped openings, thus armirukvdy material is placed in the casting.
    [2]
    2. The felt or web according to claim 1, characterized in that the endless flat belt contains molded cavities in it for equalizing the internal pressure, passing through it in width and length, while part of the cavities is interconnected with at least the corresponding two holes by crossing with them"
    [3]
    3. Felt or web according to claims 1 and 2, characterized in that the final flat belt contains cellular pores cast in it and open to the side of the through holes to bring the volume of liquid in it to a predetermined level.
