    Apparatus for making a fibrous element includes an elongate foraminous former provided by at least one foraminous belt, with a foraminous forming chamber through which said belt passes and which is formed to a hollow shape thereby. The belt is driven through the forming chamber, and fluid is extracted in a fluid extraction zone which surrounds at least part of the forming chamber and formed by a closed drainage casing. An injection nozzle injects a fibrous dispersion into the former within said forming chamber with the injection nozzle being dimensioned so as to substantially exclude the ingress of air around an interface with the walls of said belt so that the apparatus produces an elongate fibrous element having an outer core of greater density than the inner core which it surrounds.

    (54) DEVICE FOR MANUFACTURING FILTERS FOR SMOKING PRODUCTS The invention relates to the tobacco industry, in particular, to a device for producing filters for smoking articles. A device for the manufacture of filters for smoking articles is known, comprising a former comprising a perforated chamber and a driving mesh conveyor belt enclosed in a casing and an injection nozzle DL. The known device is the closest solution to the described invention to the technical essence and the achieved result. However, in the known device, the moistened mass of cellulosic fibers is supplied to the forming zone while the bands are moving and water is removed from the mass through the bands, partly due to simple drainage and partly due to the use of vacuum. The resulting fibrous structure is released from the formation zone and has a different density and insufficient compactness, and further processing, in particular compaction by means of pressure, is required to increase its compactness. The aim of the invention is to improve the quality of manufactured filters. This is achieved by the fact that in the proposed device for the manufacture of filters for smoking articles the end section of the injection nozzle is located inside the chamber so that it forms a closed hermetic cavity with the walls of the latter. In addition, the casing is divided into several consecutive sections, each of which communicates with a vacuum system to remove liquid from the filter rod being formed. At the same time the conveyor belt is made of polymeric material. In addition, polymer tape can be made of non-nylon. FIG. 1 is a block diagram of a device for producing filters for smoking articles; in fig. 2 - 5LOK turbulence formation, shaper, rotary knife mechanism, drying chamber and high-frequency dryer, located along the technological cycle; fig.Z - shaper- side view with partial section; in Fig.4.5 and 6 - sections along aa, bb
    and B-B of FIG. 3; in fig. 7 is a perforated molder chamber in longitudinal section; in fig. 8 - rotary knife mechanism, side view; in fig. 9 is a section along GGD of FIG. eight; in fig. 10 - drying chamber in longitudinal section; in fig. 11 shows a section along the DT-D of FIG. 10; in fig. 12 - section high-frequency dryer; in fig. 13 is a section for generating turbulence (generator).
    The device comprises a shaper comprising a casing 1, a perforated chamber 2, a driving mesh conveyor belt 3 and an injection nozzle 4.
    The casing 1 is divided into successively located sections 5, 6, 7 and 8 each of which communicate with the vacuum system (not shown) by means of a pipe 9 for removing liquid from the formed filter rod 10. The sections are formed by walls 11, 12, 13 and end walls 14, while on the latter end plates 15, 16 are fixed with inlet 17 and exhaust 18 pipes coaxial with the injection nozzle 4.
    The end portion 19 of the 1: 1 injection tube 4 is located inside chamber 2 and forms a closed hermetic cavity with the chamber walls.
    The conveyor belt 3 is made of a polymeric material (preferably it can be made of nylon) and passed in a flat folded form around the tension rollers 20 and roller 21 and then through the inlet pipe 17, the perforated chamber 2 and the inlet pipe 18 in the form of a cylinder and further when folded flat, around roller 22.
    The device (see Fig. 2) also contains a rotary knife mechanism 23 for cutting lengths, a drying chamber 24, a radio frequency dryer 25 and a turbulence formation unit 26 (generator) having several ribs 27 on its inner surface to form turbulence and create turbulence in the mass and thereby preventing flocculation prior to the injection of the mass into the former.
    The rotary knife mechanism 23 (see FIGS. 8, 9) has a rotor 28 with an annular V-shaped groove 29 circumferentially to hold the rod 10 tangentially in the 12 o'clock position. Inside the radial groove 30, a knife 31 is installed in the rotor, having a cutting edge 32 pivotally mounted.
    The rotor 28 is mounted on the hollow shaft 33; The blade drive shaft 34 is passed through the hollow shaft 33 and is hinged. regarding the knife; however, the rod 34 is associated with a cam mechanism (not shown) to allow
    driving the knife when the product is in the 12 o'clock position.
    Through the drying chamber 24, the drive net of the transfer belt 35 and around the tension rollers 36 and rollers 37 are also passed in a flat folded form.
    Inside the drying chamber (see Fig. 10 11), a perforated pipe 38 is installed, and the camera casing is divided into a series: compartments 39 and 40. The compartments 39 are connected by nozzles 41 to a vacuum system (not shown), and the compartments 40 are nozzles 42 with atmosphere.
    5 Inside the dryer 25 (see Fig. 12)
    there is a channel 43 through which the upper branch of the belt of the endless conveyor 44 is passed, the support for which is the drums 45. The tape
    0 conveyor is made of a material that is not exposed to heat in the radio frequency field, for example from a nylon mesh. Guides are mounted on the conveyor 46
    5 for 47 pieces of rods.
    The operation works as follows.
    A suitable pulp in the mixture with water is fed to the feeder 48 and from it by pump 49 to the dilution tank 50 in which the mixer 51 is placed. The mass is diluted to approximately 1% consistency and recycled by pump 52 through the classifier 53 to the feeder
    5 48. The fines are removed from the weight of the classifier 53 and discharged in the direction of the arrow 54.
    The diluted and classified mass is then supplied by pump 49 to
    0 tanks 55 and 56 for diluted mass, having stirrers 57 and 58, respectively. Then, from them through the pump 59, the mass is fed to the reservoir 60 of constant pressure and from it by the flow pump 61 to the block 26 for the formation of turbulence. The outlet of the pump 61 is also connected to the main 62 to return the mass to the tank 63 and eliminate the change in pressure and thereby the change in the velocity of the mass flow entering block 26 (see Fig. 1, 13).
    The fiber dispersion is injected into the former through the nozzle 4 at a corresponding speed relative to the speed of movement of the mesh conveyor belt 3. Once in the former (see Fig. 7), the fiber 64 has a boundary layer 65, which quickly drains into the first part of the drawing zone of the liquid formed the first drainage zone 66. In the second drainage zone 67 a mesh of fibers is formed on the surface of the conveyor belt 3, and also in the zone 68 a mesh begins to form
    fibers. Moreover, due to the high mass velocity relative to the conveyor belt 3, the outer surface of the fibrous mat breaks down into small flakes, which break and enter the thickening zone 69. The outer portions of the fibrous web are pressed against the conveyor belt 3, at the same time compacted into a sheath of bonded fibers.
    The mass velocity gradually decreases along the thickening zone as water is removed from the chamber through the conveyor belt and perforated chamber 2 until the fibers of the mesh cease to break. The flakes are then quickly collected on the inner surface of the fiber mesh and fill the core in the final forming zone 70. This causes the conical deposition of the layers due to the formation of the mesh initially on the conveyor belt and gradually settling it towards the center. Since the flocculi are supplied to the conically concave rear end side of the formed rod, pressure is regenerated, which contributes to the compaction of the fiber structure, as well as maintaining the proportions of residual water. The final forming zone at the end of the liquid drawing zone is a similar drying line and the solution of a paper machine.
    The tightly packed fibers in the casing reduce the speed that was drained through the conveyor belt 3 and the perforated chamber 2 when the first: of them passes through zones 69 and 70. As a result, the casing 71 has a much higher density than core 72 of the core 10 when the latter is removed from devices.
    Typically, the rod 10 is cut into certain segments during its removal from the former with the help of the knife 23 (see Figs. 8, 9).
    From the former, the water is removed from the stock through a vacuum pump 73 having a ballast tank 74 installed in the recirculation circuit, and opened to select waste waste in the direction of arrow 75 or into the tank 76. The pump 77 returns the extracted water to the tank 50.
    The moisture content in the rod 10 is from 75 to 85% by weight, but can be reduced by drying the segments 47 in the drying chamber 24 (see Fig. 10, 11) and then in the radio frequency dryer 25 from where they are discharged with a moisture content of 10%. In this form, they are further cut to a predetermined length, which is usually used in the manufacture of cigarettes.
