    The making of perforations in the tubular envelopes of finished filter cigarettes or analogous rod-shaped smokers' products for the purpose of admitting cool atmospheric air into the column of tobacco smoke is regulated automatically in dependency on one or more variable parameters including the resistance of the rod-like filler of a product to axial flow of a gaseous fluid therethrough, the permeability of the entire tubular envelope, the resistance which the entire filler or the tobacco filler of a filter cigarette offers to axial or transverse flow of a gaseous fluid or to penetration of corpuscular radiation across successive increments of the filler, the resistance which successive increments of a web of cigarette paper offer to the penetration of air or light therethrough, and/or the quantity of tobacco particles in the smokers' products. The perforations are formed by laser beams, and the regulating step includes changing the intensity of laser beams and/or the length of intervals of impingement of laser beams upon the envelopes.

    2. The method according to claim 1, also with the fact that, in order to elucidate accuracy by maintaining a predetermined ratio of intake of additional air to the smoke with large fluctuations of the natural air permeability of the padding material, applying perforation taking into account the difference between the current and the specified value, the air-permeable type of the tobacco product shell is made.
    The invention relates to the tobacco industry and can be used in methods of controlling the process of applying a perforation to the shell of tobacco products. There is a known method of controlling the process of applying perforations to the casing of tobacco products, which involves measuring the current value of the air permeability of the casing of tobacco products C13. The disadvantage of this method is that the proportion of additional air relative to tobacco smoke is not constant. The purpose of the invention is to improve the accuracy by means of maintaining a predetermined ratio of intake of additional air to smoke. This goal is achieved by the fact that in the method of controlling the process of applying perforations to the casing of tobacco products, which involves measuring the current value of the air permeability of the casing of tobacco products, applying the perforations is carried out depending on the packing of the foam against the passage of smoke. In addition, in order to improve the accuracy by maintaining a predetermined ratio of intake of additional air to smoke with large fluctuations of natural air permeable to these stuffing materials, the perforations are applied taking into account the difference between the current and specified air permeability of the tobacco product shell. Figure 1 shows the control of the perforation device, depending on the air permeability of the strip of cigarette paper; Fig.2 is the same, depending on the amount of tobacco in the tobacco rod converted into a measuring signal, dependent on the resistance to the passage of smoke provided by the packing, - in Fig. 3 - the same, depending on the resistance to the passage of smoke provided by the packing, and from the air permeability of the strip of cigarette paper; 4 is the same, depending on the air permeability of the strip of cigarette paper and the gasket resistance to the passage of smoke in the finished cigarette; in FIG. 5 the same, depending on the air permeability of the wrapper of the finished cigarette measured on the finished cigarette; fig.b - the same, depending on the resistance provided by the gasket to the passage of smoke, measured on the finished cigarette, and on the air permeability of the wrapper; 7 is the same, depending on both the amount of tobacco in the tobacco rod converted into a measuring signal, dependent on the gasket's resistance to the passage of smoke, and on the air permeability of the strip of cigarette paper, and the perforation device is located on the section of the cigarette rod of the machine for manufacturing cigarettes. To the cigarette making machine 1, tobacco fibers are supplied, or other smoking material of suitable consistency from supply tank 3 and strip 4 of wrapper from cigarette paper pulled from a reel 5. In machine 1 for the manufacture of tobacco fibers a wide and thin fibrous tape is continuously formed , and from it - the tobacco rod. The edge of the paper strip 4 is covered with one edge of paper and is continuously laid around the tobacco rod and glued together to form a cigarette rod continuously. Then, cigarettes 6 are continuously cut off from the cigarette rod on the measuring device. Therefore, the strip 4 of cigarette paper and the tobacco rod from tobacco fibers 3 supplied from the supply reservoir 3 are the main components from which the finished cigarettes 6 are prepared. After making them, cigarettes 6 are transported to machine 2 dL of attaching filters, where they are connected to filter tampons 8 supplied from the feed tank 7. For this purpose, to the filter 2, to attach filters, besides the filter swabs, is fed lane 9 akzhe noKiMJ- vayuschey paper which retracts from the spool 10, coated with adhesive and reproductive Jets on sheets. By rotating on a stationary counter-surface like a cigarette and attached along with an axial blend, the filtering tampons become finished filter cigarettes. In the manufacture of cigarettes with a double filter, external tobacco rods and double filter tampons inside, these previously named groups are joined together with glue-coated sheets to separate them, cutting off one cigarette and combining cigarettes of another row, and then transported in the same row for further processing. In order to be able to supply the filter cigarette smoke with auxiliary air, holes are made in the filter plugs, for which the perforation device 11 serves as a laser on the filter attachment machine. The laser beam 12 that leaves the laser to be controlled through the mirrors 13 and 14, as well as the lens 15, hits the filter section, where it burns a hole through a sheet of cover paper and for the most part also a paper surface. the ability to filter the tampon, so that when cigarette 6 is tightened, cold side air can flow through the openings into the filter mouthpiece, where it mixes with the flow of smoke passing through the cigar. When punching, a cigarette is placed on a drum 16, on which it is transported and held in recesses 18 by channels of air in channels 17. A rotary device in the form of a bar 19 with grooves rotates a cigarette in a section of rotation in such a way that it interrupts its rotation during rotation. the movement of the transport, relatively rotating back around the perimeter of the drum 16. Therefore, the laser beam 12 is sent by the laser to the ide impulses, can burn through the holes in the filtering tampons, which in this case are located ayuts in a single row. The temporary management start -perforirovani otde flax cigarette and laser pulses are initiated cam disk, the outer ring 20 which with the control cams 21 (initiation) and 22 (single pulses) are visible. Control signals are supplied by the initiator 23 of the approach to the input of the control device. laser. Whiter the gasket resistance of the tobacco rod of the cigarette 6 exerted by the pack permanently, the degree of ventilation can be affected by too little air permeability of the cigarette paper. For additional control of the perforation device, a sensor of measurement signals is used to air-impregnate the cigarette paper wrapper strip, the air permeability of which is measured before it is laid around the tobacco rod. The sensor of the measuring signals consists mainly of a chamber 25 of reduced pressure, along which strip 4 is supplied. The reduced pressure is created by the suction side of the fan 26. It is dependent on the air permeability of the paper and is recorded and sent as an electrical signal by a measuring transducer 27, for example, a membrane sensor. After amplification by amplifier 28 and comparison by comparison unit 29 to a predetermined signal sent by setter 30, a signal corresponding to a possible difference is fed to analog-to-digital converter 31, which converts the analog difference signal to a digital signal. This signal is slowed down by the shift register 32 in accordance with the transport time. neither strip 4 of cigarette paper, wrapped it tobacco, and, finally, cut off from him cigarette 6 to the rotator. In this case, the shift register has, for each binary digit converted into the digital form of a difference signal, a series of parallel shift steps. each one, each time after passing the transport stroke, receives from the control disk 33, which is driven synchronously with the speed of the machine, and the initiators 34 approaching their shift inputs receive a shift in the pulse that switches the binary bit one step further. When the cigarette 6, whose air permeability of the wrapper is measured by the sensor of the measurement signals, hits the rotator, the measurement signal for the air permeability of its wrapper also arrives at the output of the shift register 32. The digitized converted measurement signal is again converted to an analog signal by the digital-to-analog converter 3S and output to the input of the control device 24 laser. The adjustment is possible in such a way that the duration of the pulses of the laser beam 12 or its intensity is controlled. In accordance with the air permeability: by the thickness of the paper strip 4 by up. the cross section of the aperture is maintained at a constant ventilation rate, with the premise being made that the amount of tagback in the tobacco rod and thus the packing’s resistance to the passage of smoke in the finished cigarettes is constant. Instead of a pergeneration device designed as a laser, a perforation device operating mechanically with needles can be provided. Instead of a finished cigarette, perforation may also be applied to the covering paper, if the filtering pad has a breathable surface of sufficient uniformity. Another possibility of detecting the air permeability of the paper strip 4 is given by a sensor of measuring signals in the form of a photoelectric reading device, which mainly consists of a light source 36 with a lens 37 located on one side of the paper strip 4, and a photoelectric detector 38 with a lens 39 and an amplifier 40 located on the other side. The measuring signal sensor for the amount of tobacco in the tobacco rod 41 consists of an air guide for directing the measuring air through the tobacco rod in the form of a vacuum nozzle 42 connected to the low pressure side of the fan 26. The measuring converter 43, for example, a diaphragm sensor registers a reduced pressure , which depends on the amount of tobacco in the part of the rod through which the flow of measuring air passes. The measuring signal for the amount of tobacco in the rod section, from which the cigarette to be perforated, enhanced by amplifier 44, is made, reaches the functional sensor 45, which contains accumulated data corresponding to the density or quantity values and corresponding to the flow resistance of the smoke. for cigarettes made from rod segments, the signal sent by the functional sensor 45 passes through a block 16 of comparison and slows down the shift register 32 To the input of the control device 24 at the moment of time when the cigarette 67 is to be perforated, the cigarette 67 is manufactured from a measured length of a tobacco rod. Another measurement method for detecting the amount of tobacco in a tobacco rod 41 is a measurement signal sensor with 47 beta radiation source, which sends its beta rays transversely through the tobacco rod 41. On the other side of the tobacco rod 41, the beta rays are attenuated according to the amount of tobacco a corresponding sensitive measuring element, such as an ionization chamber, is converted into an electrical signal, which is amplified by amplifier 48 and fed to a functional generator 49. Instead of the methods described above Measuring the amount of tobacco in a tobacco rod 41 can be measured with an unrepresented capacitive measuring device. Fig. 3 shows the effect on the control unit of the device by the perforation device both depending on the amount of tobacco in the tobacco rod and depending on the air permeability of the cigarette paper, which is preferable in cases where the amount of tobacco can vary. to and breathability cigarette paper. The function generator 50 receives the measurement signals from the measurement signal sensors. It contains the accumulated values of the output signals, related to the specific values of gasket resistance to the passage of smoke and air permeability values. These output signals again through shift register 32 fall simultaneously in time with the meantime cigarette made 6 k, the input of the control device 24, controlled by the ccego, depending on the combined signal, by perforating the cigarettes in the sense of constant ventilation. For simultaneous supply of signals from the comparison units 46 and 29 to the corresponding analog-to-digital converters 31 and 51 between the comparison unit 28 and the analog-to-digital converter 31 a shift register 52 is located. If necessary, to the functional. To generator 50, an additional analog-to-digital converter 53 can supply a measurement signal corresponding to the measured value for the amount of tobacco in a cigarette. In such a case, this function generator 50 must be designed in such a way that it takes these quantity-dependent signals into account when establishing the combined control signal. The measuring device (Fig. 4) differs from the devices (Fig. 1-3) in that the measuring signal, which is dependent on the gasket resistance to the passage of smoke, is formed for the finished cigarette. A signal corresponding to the air permeability of the cigarette wrapper, in contrast, is formed for a band that is not yet wrapped. while on the paper strip of cigarette paper wrapper a measurement signal is formed for the air permeability of the cigarette wrapper and using the shift register 54 is slowed down until the cigarette 6 produced from the strip reaches the perforation device, the signal corresponding to the resistance of the packing the passage of the tobacco rod smoke, is no longer removed from the tobacco rod of the cigarette making machine 1 and is not transformed into a functional generator 49, a functional sensor 45 is converted to a value corresponding to the packing’s resistance to the passage of smoke. In this embodiment, the measurement signal is taken off. finished cigarettes.
    For this purpose, a measuring signal sensor arranged as a control drum 55 is located in front of the drum 16. The control drum has shutters 56 and 57 that are movable with control, covering the wrapper of cigarettes in the control section with sealing in such a way that the air blown into the inside of cigarettes or sucked in air flow depends only on gasketing resistance to the passage of tobacco smoke in a cigarette. Thus, the effect of breathable paper is excluded.
    The measurement signal produced by the control drum in the measuring transducer 58 and enhanced by the tamping resistance to the passage of smoke, is given after giving it a digital form to the analog-to-digital converter 59 and slows down on the path of the controlled cigarette from the control section to the perforation section in the shift register 60 to function generator 50, the output of which is again fed to the input of control device 24.
     The additional influence on the control device 24 may be carried out by a measuring signal formed depending on the amount of tobacco in the cigarette. This signal is produced by a sensor of measuring signals (beta radiation source 47 and beta-sensitive measuring element 61) by means of a portion of a tobacco rod 41 from which a cigarette is to be perfused. The signal is decelerated by imparting a digital form in the analog-to-digital converter 53 using the shift register 52. In case of additional processing, depending on the number of the measuring signal, the function generator 50 must accumulate the corresponding values for additional quantitative functions
    The measuring device (Fig. 5) differs from the device (Fig. 4) in that the signal corresponding to the air permeability of the wrapper of the finished cigarette is formed by the reference drum.
    At the measuring site, to the ends of the cigarettes on the test drum 55, a test pressure is applied through the throttle. Measuring transducer 63 converts pressure into an electrical signal and amplifies it. Signal; the corresponding amount of air formed by the measuring transducer and the corresponding air permeability of the wrapper are compared in comparison unit 64 with the transmitter 65 sent. The signal and difference signal through a decelerating element 66, for example a shift register, is fed to the control unit 24.
    The measuring device (Fig. 6) (Differs from the device (Fig. 4) in that the air permeability dependent and gas pressure resistance to smoke cooling for the finished Cigarette is recorded using a control drum. In addition, an additional effect is provided on the control device of the perforation device in the sense of a correction depending on the control signal output from the control device for the holes made in the cigarette.
    The control drum 55. contains one control section for the air permeability of the cigarette paper of the finished cigarette 6, on which the measuring transducer 1 "1 63" with open flaps 56 and 577 records a drop in pressure due to the compressed air flowing through the wrapper to both ends of the cigarette.
    The measurement signal is converted by the IB digital view in the analog-to-digital converter 67 and the shift register 68 receiving its shift pulses from the analog-digital converter 67 the clock pulses are slowed by four strokes, the cigarette 6 being monitored will not be transported from one measuring point to another uchas.tku.
    Thereafter, the slow signal by the digital-to-analog converter 69 is again converted into an analog signal and fed to the input of the functional sensor 70.
    In the second measuring section, corresponding to the first measuring section, with the flaps 56 and 57 closed, sealing the wrapper of the cigarette from the outside. The measuring transducer 71 produces an electrical measuring signal depending on the packing of the passage of smoke and sending it to the input of the function sensor 70. The latter sets ii3 accumulated functional quantities for interconnection between the cross-sections of the holes and the values exhibited by the packing of the passage of smoke or the corresponding air flow. the breathability of the output signal, compared in block 72 comparison with a predetermined signal sent from the unit 73. The resistive signal through the amplifier 74 loads the control input to the control unit 24 of the perforating device, which Tenepfe bores through depending on the air permeability and the gasket provided from the resistance to the passage of smoke, measured not long before entering the perforating device. Additionally, there may be an effect on the control device 24 depending on the amount of tobacco in the cigarette. Behind the perforation device-a is located a control device for cross-sections of the holes made in the form of a control drum at 26. The latter is equipped with flaps 76 and 77, with which you can close the wrapper of the controlled cigarette b outside the hole section. Measuring transducer 78 generates a signal corresponding to breathability holes, which in comparison unit 79 is compared with the signal sent by unit 80, and a slowing down element in the form of a four-step shift register 81 and force Spruce 82 is supplied to the control coil of the electromagnetic Cl Pan 83 air conduit 84 under pressure, running to the exhaust-nozzle, situated in the four recesses later. The target value for the control drum 75 may coincide with the control signal of the control device 24. In this case, it is determined whether the actual perforation result corresponds to the desired result that must be maintained in order to form the required degree of ventilation. The measuring signals of the control drum 75 can be supplied to the integrating circuit 85, which, through the input from the control device 24, makes corrections if the actual performance results deviate for a long time from the required ones .; The device (Fig. 7) differs from the devices (Figs. 1-6) in that the perforation device is not located on the filter attachment machine on the cigarette making machine, namely, in a portion of the cigarette rod. The laser device is located on the section of the finished cigarette center 85 on the cigarette making machine 1 (visible bonding chamber 87 and so-called format tape 88), on which the tobacco rod 41 is already wrapped with the glued overlap of the cigarette paper strip 4. The rotating cutting device 89 from the cigarette rod 86 in places (dashed) 90 cut off the finished cigarettes, which then as so-called simple cigarettes can be fed directly to the packaging, or to the machine 2 (Fig.7) to attach filters for attaching the filtering tampon. The laser beam 12 is guided in such a way that it burns through the holes in the upper portion of the cigarette rod 86, where the so-called glued seam 91 of the rod is located. The control device 24 is connected via a shift register 32 to a function generator 50. The shift register 32 slows down a control signal generated by a function generator 50 formed from a measuring signal dependent on the amount of tobacco converted by the function sensor 45 to a signal from the dependent signal provided by the packing from the porosity of the measuring signal, until the corresponding section of the rod, for which the measuring signals are received, falls on Astok laser device. At the same time, the measurement signal, which depends on the air permeability of the cigarette paper strip 4, also slows down depending on the time taken for transporting the paper from the measurement point to the location of the tobacco quantity by the shift register 52. in addition to the control signal 24 that the smoke resistance to the control device It can also be influenced by a Signal, which can be fed to a function generator 50 through an analog-to-digital converter 53. The initiation of laser pulses for cutting a cigarette rod corresponding to a finished cigarette 6 cut from a cigarette center is a function of a control cam 21 in conjunction with an approximation initiator 23; initiating individual pulses for a rod segment is a function of control cams 22 in conjunction with an initiator 23 approximation . Laser control is possible by controlling the time duration and / or: energy. laser beam pulses. The device 24 instead of the combined signal provided by the gasket resistance to the passage of smoke
    and porosity can be controlled by signals depending only on one measured quantity, i.e. from the porosity or from the gasket resistance to the passage of smoke, or from the amount of tobacco in one segment of the rod.
    The device (Fig. 7) can be modified by positioning the device with laser beams on the site of the cigarette making machine 1, to which individual cigarettes 6 come from the cutting device 89. / GJL l teas J, J
