    2. The device according to claim 1, wherein it is provided with a means of cleaning the working areas, made in the form of at least one cylindrical brush mounted for rotation.
    3. The device according to claim 1, characterized in that the anti-roller is mounted for movement relative to the roller with recesses by means of a drive mechanism for adjusting the gap between them,
    The invention relates to devices for installing filters on tobacco products, and more specifically to devices in which cigarettes and filters are attached to one another by means of adhesive connecting tapes.
    There is a known method of fastening filters, in which cigarettes are installed in pairs along an axis, and a double-length filter is inserted between them, which is cut into one cigarette. A group formed of two cigarettes and lengths is connected by means of tissue paper adhesive tape, which is wrapped to cover the length of the filter and each of the cigarettes. . These operations are performed in a device for attaching filters to tobacco rods, comprising a rotating carrier drum with longitudinal grooves communicated with a vacuum system and used to move the lengths of the filters. Adhesive tape is fed to the periphery of the carrier drum and held there by suction.
    A fixed concave plate, coaxially with the carrier drum and spaced apart, which in fact corresponds to the diameter of the cigarette, is connected by friction with the groups, causing them to rotate around adhesive tapes that are wrapped around them and thus connected to each other.
    However, the concave plate is slightly weakened and thus there is a danger of a complete failure of the machine to install the filters. Indeed, sticky marks remain on the plate during operation of the machine and they collect
    dust parts of cigarettes, as well as tapes that did not fall on the grztpy.
    As a consequence, it is necessary to periodically stop the filter installation machine and the cigarette production machine downstream for a certain time in order to clean the plate, and this requires a certain amount of labor.
    A device for attaching filters to tobacco rods, comprising means for moving in the transverse direction of the tobacco rod and filters, made in the form of a roller with grooves communicated with a vacuum system, and located with a clearance from it, an anti-roller element that is rotatably mounted along a horizontal axis. 2J,
    However, due to the surface of the anti-roller element being flexible, damage to a number of cigarettes is observed, which reduces the performance of the device.
    The purpose of the invention is to improve the performance of the device.
    The goal is achieved by the fact that in a device for attaching filters to tobacco rods, comprising means for moving in the transverse direction of the tobacco rod and filters, performed in the form of a roller with grooves communicated with the vacuum system, and located with a gap from it
    an anti-roller element mounted rotatably about a horizontal axis, the anti-roller element is rigid and on it. surfaces are formed
    at least two concave working area, located in the same plane at an angle to one another.
    The device can be equipped with a means of cleaning, working areas, made in the form of at least one cylindrical brush mounted rotatably.
    In addition, the anti-roller,; the element can be mounted for movement relative to the roller with recesses by means of a drive mechanism for adjusting the gap between them.
    FIG. 1 schematically shows a device, front view; in fig. 2 - the same, option of execution.
    The device for attaching the filters to the tobacco rods comprises a roller 1 with a horizontal axis, supported by the shaft 2 and rotating counterclockwise. At the periphery of the roller, longitudinal grooves 3 are made for products 4 consisting of two tobacco rods and double-length filters arranged between them.
    Close to roller 1 there is a po-. 5, resting on shaft 6, parallel to shaft 2, provided with peripheral recesses 7. Roller 5 rotates clockwise with the same peripheral speed as roller 1, recesses 7 - are paired with notches 3 and they form into the utricylindrical cavity 8, which connects to a suction source (not shown).
    The notches 7 are connected through the channels 9, which pass through the cylindrical wall 10 of the roller 5 with the chamber 8. The wall 10 also has a passage through it and between each pair of notches 7 of the holes or aisles 11.
    The roller 12 with a horizontal axis resting on the shaft 13 is located closely with the lower left surface of the roller 5 and is provided with notches 14 equally spaced, the inner surface of which corresponds to the notches 3 and 7. The roller 12 rotates counterclockwise with the same peripheral at a speed similar to that of the roller 5, the recesses 14 are mated in series with the recesses 7.
    A strip 15 of paper material is glued on top, taken from a roller (not shown) and fed by means (not shown) tangentially to the periphery of roller 5 at a speed of movement which is less than the peripheral speed of the latter.
    The edge of the belt 15 touches the roller 5 and is held tightly with it by suction through the holes 11.
    Upstream of the surface, where the rollers 1 and 5 are adjacent, the tape 15 is cut off by a rotating knife 16 or a cutting tool having four blades 17 at the periphery at an early distance, which interact with the surface of the roller 5 to provide cutting.
    -Beather 16, rotating counter-clockwise, separates the substrate from the strip 15 of the strip 18, intended to be connected to one another tobacco rods with filters in the articles 4.
    Due to the difference between the peripheral speed of the roller 5 and the linear speed of the strip 15, the leading edge of the latter slides constantly along the roller 5 in such a way that after the strip is cut off, it slides itself to the roller 5, settling accordingly with another strip.
    Located near the roller 5 between the rollers 1 and 12, the anti-throttling element 19 is attached to the shaft 20 or carrying means parallel to the shaft 6.
    The anti-roller element 19 has two concave working sections 21 and 22 which are located symmetrically relative to the axial plane of the element 19.
    Section 21 is coaxial with roller 5 and is located at a distance slightly smaller than the diameter of the products 4, and the length of the arc bordering them is actually similar to the step between two notches 7.
    A cylindrical brush 24 is rigidly fixed on the shaft 23 in such a way that it contacts the work area 22. The suction effect applied to the surface of the roller 5 through the holes 8 and 11 is not enough.
    As a consequence, in the cavity 8, the arc walls 25 and 26 are fastened, respectively, coaxially with the roller 5 and adapted to the inner surface of the cylindrical wall 10 in the area of the mentioned areas.
    During operation, the devices of the product 4 are transmitted sequentially from the recesses 3 of the roller 1 to the recesses 7 of the roller 5 and are held in the last f by suction effect through the holes 9.
    After the strips 18 are separated from the belt 15 by the knife 16, they remain on the roller 5 due to the suction effect exerted through the apertures 11. Each of them is located between two successive recesses 7 which have a leading edge counted in the direction of rotation of the roller 5 , at the side of the recess 7, located downstream.
    When the roller position is reached, the groups are connected by friction with the section 21 of the element 19 and are wound on the respective strips 18, which are wound around them, connecting one element with another.
    During the coiling operation, the group is protruded from its recess 7 and then pulled in when the operation is completed, to the next recess 7. For products 4 coming out without damage, said recesses 7 must be of very limited depth.
    During the subsequent winding operation, the groups reach the roller 12, where they are placed in the recesses 14 and transferred to the following processing devices (not shown).
    While section 21 performs its winding function on product 4, it is zipindric. the brush 24 may, during its rotation, clean the area 22 while the machine is running to strengthen the filters.
    By 180 degrees, the anti-roller element 19 around the axis of the shaft 20 allows the portions 21 and 22 to exchange places.
    Periodically or even at random periods without interrupting the operation of the filter installation site, the change of the two sections 21 and 22 can be carried out fully automatically or manually.
    The operation of cleaning the area, which is installed in the non-operating position, can be performed instead of the cleaning device with a rotating brush 24, with any other mechanical device or with hands
    It should also be noted that, in accordance with the advantages of the proposed device, the plates, which are placed in an inoperative position, can also be replaced with 5 others during the operation of the machine to strengthen the filters. This capability is assessed by asths in the case where the concave surfaces of the portions 21 and 22 are provided with very fine needles, 0 which spoil much faster, and serve to perforate the products 4 in order to create aerated cigarettes,
    Another form of embodiment of the device proposed is that the anti-roller element can be provided with more than two anti-roller areas.
    As an example (Fig. 2), 0 {occupies the anti-roller element 27, equipped with three working sections 28, which are equally spaced from one another. The roller 5 must be positioned from
    5 with respect to sections 28 along an arc of such length as to prevent the anti-roller element 27 from rotating freely around the axis of the shaft 20, the possibility is considered when using drive means with which it is possible to move the element 27 so that rotation takes place.
    Dp these goals shaft 20 (Fig. 2)
    5 is supported in a rotating upper shoulder of the two shoulders; about the lever 29. The inner platform of the latter is movably connected to the pin 30, parallel to the shaft 20 and representing integral with the vertical wall 31, which is part of the frame of the filter reinforcement device. The wall 31 is also held by the shaft 23 of the brush 24 (the method of fastening
    5 is not shown) and is provided with an arc hole or slot 32 with a center of curvature on the axis of the pin 30 through which the shaft 20 passes.
    Tension spring 33 connects
    g - the lower arm of the lever 29 with the pin 34, which is integral with the wall 31, and retracts the lever 29 to the right. During operation of the device, the spring 33 is opposed by a stop on the lever 29 attached to the wall 31.
    The anti-roller element 27 is deflected automatically or manually by rotating the lever 29 BOKityr pin 30 clockwise.
    In the proposed device, in which the anti-roller element is rigid, there are two working sections instead of tapes and the possibility of precise positioning with respect to
    to roller 5, the effect of pressure on cigarettes is minimized and the stopping time of the raspberry operation is reduced, since the used working section is replaced by a cleaned section by turning the anti-roller element during device operation.
