    The device can be equipped with a reflector 6 mounted for rotation about the axis of the drum 1 from the driving gear 7 fixed on the end of the shaft 2 of the drum 1.
    The length of the guide arc 5 is set by the formula 1 G P, where 1 is the arc length, g is the distance between the products on the drum, n is the number of holes formed on each ring of the products 3. In addition, the drive socket 4 can be made the form of at least one sleeve, and its drive includes a set of gears,
    containing end wheels 8.9. The wheel 8 is fixed by key connection (not shown) on the shaft 2 of the drum 1, and the wheel 9 is mounted on the shaft 10 of the slot 4 also by means of a key coupling (not shown), while the slot 4 is rigidly fixed on the shaft 10. includes a slider 11 mounted to move parallel to the axis of the product 3 from the cam mechanism including a drum cam 12 with a groove 13 of such a shape to communicate during each revolution of the drum 1 near the axis
    tubular shaft 2 each slide 11 reciprocating movement between the extended working position
    (shown in the upper part of Fig. 1) and the retracted resting position (shown in the lower part of Fig. 1). For this, the groove 13 is shaped so as to support each slide 11 5 in its working position along the arc of its movement.
    As shown in FIG. 1, the drum 1 comprises an inner end flange 14, the inner periphery of which 10 is rigidly connected to the outer periphery of the annular flange 15 of the tubular shaft 2 coaxially with the drum 1. The shaft 2 is passed through the drum 1 and supports the gear 16 at its end opposite to t5 , clutter with a source of motion, (not shown). The intermediate part of the shaft 2 is passed through the hole 17 in the fixed wall 18 of the machine for 20 filters. The outer surface of the wall 18 is connected to the flange 19 of the tubular body 20 coaxially with the shaft 2 and passed through the hole 17 in the direction of the gear wheel 16. With the outer 25 surface of the flange 19, through a plurality of axial screws 21, another tubular body 22 coaxially connected to the tubular housing 20 and supporting with rotation or with this housing 20 shaft 2 with two bearings 23, the first of which is installed in the housing 20, and the second in the housing 22.
    The tubular body 22 comprises a cylindrical outer surface, which is rotatably connected by a hermetic seal to the inner cylindrical surface of the drum 1 and contains a groove 24 located in a plane perpendicular to the axis of the shaft 2 and divided into two sections. Groove 24 communicates, on the one hand, with a vacuum source, and on the other, selectively, with a multitude of radio buttons from | 5 versts 25, going inwards from the bottom of each slot 4. I
    From the other surface of drum 1,
    facing in wall 18, extends one axial pin 26 to each 50: each nest 4, which serve as a prismatic sliding guide for the corresponding slide 11. The latter forms part of the actuator driven towards the cigarette 3, Each slider 11 includes a tubular sleeve 27 that is slidably connected and angled to a corresponding pin 26 and carrying a radial pin supporting the bearing 28 in rotation. The IR can rotate in contact with the side walls of the groove 13 formed in the cylindrical surface of the tubular body 22, and together with it is a drum cam 12. The groove 13 is shaped so that during each revolution of the drum 1 near the shaft axis 2 each slide 11 - reciprocating motion between the opened working position (in the upper part of Fig. 1) and the extended rest position (in the lower part of Fig. 1). For this purpose, the groove 13 is shaped so as to support each slide 11 in its working position along the arc of its movement.
    From each sleeve 27 moves outward in the direction opposite to the bearing 28, the protrusion 29, through which the drilling 30 is made, coaxially with the corresponding slot 4 and the shaft 10 accommodating for rotation. This shaft carries the elastic sleeve connected to its end facing the slot 4. 31, the inner diameter of which is such that it allows the connection with a weak force of the sleeve 31 and one end of the corresponding cigarette 3 which is located in the corresponding socket 4.
    A set of gears 32 includes a gear 33, mounted on a key on a shaft 34, supported at its ends rotatably on tubular bodies 20 and 22, and mounted inside a cavity formed between these elements. The shaft 34 carries a gear 35, which is mounted on the key, which is supported by a gear 36 inside the cavity and is connected to the internal teeth of the cylindrical ring 37, coaxially with the shaft 2 and supported by bearings 38 inside the tubular bodies 20 and 22. the surface of the ring 37 is rigidly connected to the gear wheel 39, which is also coaxially with the shaft 2 and connected with the gear wheels 9 of all the shafts 10.
    Through the shaft 2, a tubular shaft 41 is passed rotatably in the bearings 40, one end of which protrudes from the shaft 2 to the end of the gear wheel 16 and carries the gear wheel 7 mounted on the key and connected to the source of movement, and the other end extends beyond the flange 15. the end of shaft 2 and connects an elongated axial slot 42. A pulsed laser beam passes inside shaft 41
    43 generated by the laser generator 0 13 cam 12 is supported axially
    44 facing the shaft end 41, the position of each slider 11 is 11
    a gear wheel 7. The beam is deflected through the slot 42 of the shaft 41 by means of two reflectors 6 installed along the axis of the shaft 41, and the reflector on which the beam 43 falls first is a semi-transparent mirror that divides the beam 43 into two bundles 45 and 46, which are focused by respective lenses 47 and 48, and onto cigarette filters so as to form openings 49 along ring 50.
    When using the device, the product 3 is fed to the sockets 4 on the drum 1 from the supply drum 51, tangential relative to it and also equipped with sockets 52. Each of the sockets 32 when reaching the point of contact with the drum 1 releases the corresponding product 3, which occupies the corresponding socket 4 and is held in it due to suction.
    At each revolution of the shaft 41, the generator 44 generates a series of p laser pulses emitted at a constant frequency for a period of time
    This continues until
    each article 3 (cigarette) has not reached -35; a slot 42 intersects the arc of the perforation of the arc of the arc (arc of perforation), and of the gap of the AB. Consequently, each time the cigarette is held by the house of the shaft 41, the generator 44 is withdrawn into the corresponding socket by filling the hole in the cigarettes 3, guiding 5. The first part of the groove is successively located along the arc 24 begins in accordance with the perforation point 40 AB Thus, in contact between the reels 1 and 51, and during their movement along the arc, they are curtailed in accordance with the beginning of the perforating arc AB in the advancement direction of cigarettes 3, while the other part of the groove 24 begins in accordance with the end of the perforating arc
    perforation AB each cigarette 3 is exposed to the laser beam n times, so when it exits 45 it contains two rings 50 of n holes 49 evenly distributed around cigarette 3 due to the rotation of the cigarette near its own axis as a result of connecting with the corresponding arc AB and ends in accordance with the touch point between the drum 1 and the output drum 53. The output drum 53 removes cigarettes from the sockets 50 of the rotating rotary sleeve 31. 4 by suction and takes them to the axial sockets 54.
    perforation AB each si is exposed to the la beam n times, so when it contains 45 it contains two rings 50 of volume 49, evenly distributing around cigarette 3 due to a cigarette around its own connection result with
    By increasing the diameter of the drum, it is possible to increase the length of the arc rotor AB, by doing it, for example, by 2n steps of diversity. In tea, the speed of rotation of the cigars of their own axes in the cut-off reel of the sleeves 32 reduces half the speed, while the speed () is T1
    When cigarettes are transferred to drum 1 at the point of contact with drum 53, slide blocks 11 are retracted in a resting position, and due to the inclination of the groove 13, cam 12 is shifted to its working position in coincidence with the beginning of the hole punching arc. In each case, each slider 11 moves in the axial direction so that the sleeve 31 associated with it reaches the grip position of the end of the corresponding cigarette 3 at the same time as the suction stops through the holes 25. During this advance of the slider 11 by means of a groove
    determines the separation of each sleeve 32 with the corresponding cigarette 3 when resuming suction through the openings 25.
    The gear ratio of the gear set is such that during the passage of each cigarette 3 along the arc of perforation AB it makes a full turn around its own axis by connecting it with the corresponding sleeve 32.
    The tubular shaft 41 is designed to rotate with such an angular velocity,
    so that the full rotation of the shaft 41 corresponds to the advancement by one step of spacing P of cigarettes 3. In addition, the length of the arc of perforation of the AB is equal to the number n of spacing steps p, where n is the number
    holes 49 of each ring 50.
    At each revolution of the shaft 41, the generator 44 generates a series of p laser pulses emitted at a constant frequency for a period of time
    slot 42 intersects the arc of perforation AB. Consequently, at each revolution of the shaft 41, the generator 44 makes a hole in n cigarettes 3, successively located along the arc of punching AB. Thus, during its movement along the arc
    slot 42 intersects the arc of perforation AB. Consequently, at each revolution of the shaft 41, the generator 44 makes a hole in n cigarettes 3, which are successively located along the perforation arc AB. Thus, during its movement along the arc
    31 rotating sleeve.
    perforation AB each cigarette 3 is exposed to the laser beam n times, therefore, when it exits, it contains two rings 50 of n holes 49 evenly distributed around the cigarette 3 due to the rotation of the cigarette near its own axis as a result of connection with the corresponding rotating sleeve 31.
    By increasing the diameter of the drum 1, it is possible to increase the length of the perforation arc AB, making it, for example, equal to 2p separation steps. In this case, the speed of rotation of the cigarettes 3 around their own axes as a result of their capture by the sleeves 32 is reduced by half, while the speed () is T1 p-tsnich
    shaft 41 is changed so that each complete revolution around its own axis corresponds to the advancement of cigarette 3 by two steps of spacing p. Consequently, if the number of pulses emitted by the generator 44 remains constant and equal to n, with each revolution of shaft 41, cigarette 3 is exposed to a laser beam twice as often, but each cigarette 3 always has two rings along n holes 49 after passing through the perforation arc.
    The presence in the means for imparting rotation to the products of a retention device made in the form of a drive socket with a guide arc 5 covering the drum at an angle of less than 360 will prevent tobacco from falling into products when they are drilled into the hole to increase the quality of cigarettes. .
