    A method for manufacturing a loose screen-stencil-roller showing at its cylindrical outer surface a pattern of indentations, comprising the steps of starting with a smooth-walled support cylinder (1) being either a hollow thick-walled roller or a massive roller, upon which a thin-walled sieve (2) is pushed, after which the sieve (2) is clampingly secured upon said cylinder (1); the invention also deals with an apparatus for applying this method comprising a support cylinder (1) with fluid passages (10, 11, 14) enabling the mounting and removal of the sieve (2) around its outer periphery.

    The invention relates to a method for producing rollers which are provided with a pattern of recesses on their α-outer cylindrical surface.
    The purpose of the invention is to reduce the cost of manufacturing and twisting service life.
    The drawing shows a diagram of the implementation of the method.
    The method is carried out as follows.
    I A hollow supporting cylinder 1 is chrome-coated with its outer surface I or is coated with a non-perforated thin I chrome sleeve 2. Axis 3 can be mounted vertically. The supporting hollow cylinder 1 pulls on the I grid 4, which is previously fitted in line with the void of the 1st cylinder 1.
    i From this end, the apertures on the cylindrical grid 4 are first closed, for example, by applying a layer to be removed afterwards which is impermeable to the medium. Both ends of the hollow cylinder 1 are provided with supporting axles 5 and 6, clamped by means of disk-shaped parts 7 and 8 at the corresponding ends of the cylinder. These parts 7 and 8 can be limited by a ring 9 on the inner surface of the hollow cylinder 1. At one end of the supporting hollow cylinder 1, it is made from several radial holes Y. They go to the outer surface: 1 of the hollow cylinder — and are connected to the axial channel 11 in the disc-shaped part 7. Each of the channels 11 has a non- (sharp edge or closing lid 12 on the corresponding feather, the full surface of the hollow cylinder. The second open end of these channels 1 is reported to the inner space 13 of the supporting hollow cylinder). pa I. The disk-shaped part 8 on the other OM of the end of the hollow cylinder 1 has a "one axial channel 14, which communicates with one side with space 13 and the other side with a connecting piece nipple 15. The latter can be connected through a sleeve with a source of pressure medium (not shown ayy), most often with compressed air. Grid 4, which should be monitored
    on the supporting hollow cylinder 1, has such a diameter that it is held with a clamp on it. To mount mesh 4 on


    the hollow cylinder, the outer part of the hollow cylinder behind the holes 10 has a slightly conical shape ,. The grid 4 is tensioned onto the chamfered conical part to overlap the aperture; Tiy 10. Thereafter, the medium is supplied under pressure into the space 13 through the nipple 15 and the channel 14 so that (closed) the grid A is slightly stretched, providing further tension of the grid on the hollow base cylinder 1. The pressurized medium somewhat stretches the grid 4 and at the same time acts as a lubricant during the movement of this grid over the supporting cylinder.
    After this movement is completed, the message with the pressure medium source can be interrupted, after which this medium flows out, so that the mesh 4 is mounted by pressing on the supporting hollow cylinder 1. After that, the impermeable outer layer of the mesh can be removed (for example, promg shki), after which the mesh roller is ready.
    The removal of mesh 4 can be done in various ways. In the case where the recovery goal is not pursued, the grid can simply be cut. This can be done with a worn or damaged mesh. However, when the goal of replacing a still usable mesh is pursued, it is first applied an environment-impermeable layer on the inner surface of the mesh. The mesh may be made impermeable by closing the openings, for example by crimping or an auxiliary device. Only after this can removal be carried out after the supply of media) under pressure into the narrow space between the supporting hollow cylinder and the grid.
    The grid can be supplied from the inside with hidden tension forces and can be freely put on with a certain gap on the supporting hollow cylinder and fixed by means of heat treatment on this cylinder.
    When using a mesh with a fineness of 10-500 lines in mesh 4, a mesh roller of any desired type can be obtained. The thickness of the mesh 4 can lie between 65-80 microns and the percentage permeability of the holes can be up to 29-30%. Impenetrable

    Claims (5)
    [1]
    1. A method of manufacturing a mesh roller, in which two blanks in the form of hollow cylinders, one of which is a supporting roller, is installed one into the other, temporarily changing the diameter of one of the hollow cylinders, connecting them and restoring the diameter of the hollow cylinder to the original dimensions after assembly, and - In order to reduce manufacturing costs and increase service life, the outer core cylinder is in the form of a mesh, with a temporary change in diameter produced on the mesh.

    [2]
    2. A method according to claim 1, characterized in that the holes in the mesh are pre-closed with a substance that is not permeable to the liquid, and the change in the diameter of the -grid is made by stretching it in the radial direction, feeding the liquid medium under pressure into the cavity between the supporting hollow cylinder and mesh.
    [3]
    3. The method according to claim 2, characterized in that the impermeable liquid dp of the liquid is applied onto the inner surface of the grid,
    [4]
    4. A method according to Claims 2 and 3, characterized in that the pre-holes in the mesh are closed, for example with polyvinyl acetate.
    [5]
    5. Method POP.1, which is different from the fact that a pre-stressed structure is used as a grid, the voltage of which is relaxed by heating after the connection of hollow cylinders.
