    Apparatus for making perforations in continuous or interrupted webs of cigarette paper or the like has one or more perforating units serving to direct radiant or electrical energy against selected portions of the web to make holes therein. That portion of each perforating unit which surrounds the locus of propagation of energy beyond the respective perforating unit is externally cooled and cleaned by one or more streams of compressed gas which ensure that such portion cannot accumulate solid combustion products which could interfere with the propagation of energy toward the web. The stream or streams are furnished by the orifices of nozzles which can be provided in the carrier or carriers for the perforating units or can be outwardly adjacent to the carrier or carriers.

    The invention relates to a device for perforating a moving thin material, in particular a covering wrapping material for tobacco products.
    The purpose of the invention is to increase the reliability of the removal of carbon particles from the surface of the radiating head and to improve the quality of perforation.
    Figure 1 shows the device, a longitudinal section; Fig. 2 shows a radiating head, a longitudinal section; Fig. 3 shows schematically a device for perforating cigarettes; 4 is a cross-sectional cut-out of the device for electroperforation of the moving tape material.
    A device for perforating double material 1 of a material in the form of paper tape 1 consists of a frame 2 with holes 3 in which radiating heads 4 are installed. The radiating heads are displaced (not shown) one relative to another transversely to the direction of movement of the paper tape 1 for
    a paper tape of 1 track with three rows of holes tight to each other.
    In the frame 2, there is further an opening 5 for the entrance of the coherent beam 6, emerging from the pulsed laser 7 and changing the direction one or more times with the help of mirror 8 (shown by dotted lines). A mirror 9 is installed in the hole 5, a hole 10 branches off from the hole 5 almost under the right angle, in which mirrors 11-13 are installed one after the other.
    Mirror 11 reflects a third of the laser beam falling on it and passes two-thirds of the beam. Mirror 12 is semipermeable, and mirror 13 is fully reflective. So
    Thus, on each radiating head 4 one third of the lasf beam arrives in the frame through the hole 5.
    In Fig. 1, a series of radiating heads 4 is shown, performed in a paper tape 1 track with three passes in a row of rows of holes. If in a paper tape 1 for making cigarettes with a double filter it is necessary to make two lanes with three passing through a series of rows of holes in each, then in frame 2 a second such set of radiating heads is installed. In hole 5 there are in this case two mirrors 9 one after another, the front of which is semi-permeable. In this case, a pole part of the radiation intensity is fed to each radiating head. The radiating head A (Fig. 2) consists of a body 14 mounted in the aperture 3 of the frame 2. In the body of the radiating head 4 a focusing lens 16 is attached by means of a screw ring 15, which is an inlet window of the radiating head. On the outer perimeter of the housing there is an annular canadian 17, which through the opening 18 is connected to the channel 19 in the frame, the ace. Through another opening 20, an annular groove 17 is connected to the inner space of the housing 14. According to the invention, there is another opening 21 connected to the channel 19 and to the nozzle 22. The axis of the latter is oriented to the surface of the radiating head adjacent to its radiation surface. The upper edge of the housing 14 is in close proximity to the outlet 23 of the radiating head 4. Through the connecting element 24 (Fig. 1), the channel 19 is connected to an overpressure source 25 to obtain a gas stream. The gas used is, for example, air or protective gas. Figure 2 shows the hole 21 with the nozzle 22, which directs the gas stream to the upper edge of the radiating head. The invention also provides for the arrangement of several such nozzles around the radiating head or the use of an annular nozzle that partially or completely covers the radiating head. The paper tape 1 passes through the guide surfaces formed by the areas of the circumferential surfaces of the fixed bolts 26 to 28, which are located on the side of the paper tape 1 facing in the direction opposite to the radiating heads 4, in close proximity to the corresponding punched point. They are located along an arc that is convex with respect to the radiating heads. Due to this, a strict direction of the tape occurs - and a certain position of the perforated section of the paper tape is provided with respect to the corresponding radiating head 4. It is also possible to arrange guide bolts 26 to 28 on the side of the paper tape 1 facing the radiating heads 4. In this case they are located. I lag pc with an interval relative to one another along an arc concave toward the radiating heads. In this case (not shown) they are located in the immediate vicinity of the corresponding perforation point so that the foci of the radiating heads are always as precisely as possible in the plane of the tape. The paper tape 1 and the surface of the frame 2 form the borders of the channel. To form an air flow through this channel, there is a ventilation slot 29 in the rear wall of the machine. On the side of the paper tape 1 facing the direction opposite to the radiating heads, there is a cover 30, which with the paper tape 1 forms a space 31 into which the ventilation slot goes 32. Below is the principle of the proposed device. From the radiation source, preferably laser 7, the coherent beam 33, after a single or multiple change of direction (shown by a dashed mirror 8), passes through the opening 5 into the frame 2. From the mirror 9, the beam 33 is directed to the opening 10, which is located almost at right angles to hole 5. Here it hits mirror 11, reflecting a third of the beam, into the corresponding emitting head 4. Of the two thirds of the laser beam passing through the mirror 11, half is reflected in the semipermeable mirror 12, the last third of the divided learning falls into the result Reflection in the mirror 13 to the right radiating head. From the lenses 16 of the radiating heads 4, the area of the rays is focused in the plane of the perforated paper tape 1. The laer operates in a pulsing mode, which results in the formation of three perforated radiating heads arranged in a row and arranged sideways in relation to one another. as a path with three rows of holes passing in a row. Close to the perforation points, the paper tape is guided through the fixed bolts 26, 28, as a result of which it is constantly passing through the focal planes of the radiating heads. The connecting element 24 of the frame 2 is connected to the pressure source 25. Through the channel 19 and the hole 18, as well as the annular groove 17 and the hole 20, the gas flow is formed in the inner space of the housing 14 of the radiating head 4. This gas flow cools the radiating head and the optics inside it and prevents particles from the carbon from perforation through the outlet hole 23 into the radiating head. Through the hole 21 connected to the channel 19 and thus connected to the source 25 pressurem, the gas jet through the nozzle 22 is directed towards the upper edge of the radiating head 4. This gas jet prepares There is a accumulation of carbon particles in the upper edge zone of the circumferential surface of the radiating head and the formation of carbon monoxide there, which can lead to clogging of the outlet orifice and thereby reduce the radiation power of the radiating head. Carbon monoxide particles, which, due to the movement of the perforated material, tend to accumulate on the side of the upper edge where the flow is downward, are blown off by a gas jet and are pulled out from the space between the moving tape material and the surface of the frame 2 through the ventilation slot 32. At the same time through the ventilation slot 29 Carbon monoxide particles that fall on the other side of the paper ribbon are drawn from space 31. In order to obtain a gas jet directed at the edge of the radiating head, air or protective gas is primarily used. Fig. 3 schematically shows an example of a device for perforating cigarettes. The cigarettes 34 to be perforated are fed to a rotating drum 35 in the direction of the scientific research institute arrows. The cylinder 36, having a recess 37 outside and around the perimeter and protrusions 38, is parallel to the drum in such a way that its protrusions 38, which serve as the surfaces of the counter rollers, touch just around the circumference of the cigarettes supplied by the rotating drum. The cylinder 38 rotates in the direction opposite to the direction of rotation of the drum 35. When the corresponding cigarette rolls between the surface of the drum 35 and the surface of the protrusion 38 of the cylinder 36, it retains its position. For perforating cigarettes 34, a radiating head 39 is provided. Its internal structure corresponds to the design of the radiating head 4. A laser 40 is provided to obtain a coherent beam, the beam of which from the radiating head 41 is focused directly on the cigarette 34 rotating between the surface of the rotating drum 35 and the protrusion 38 of the cylinder 36. As a result, a ring of uniform openings forms on the cigarette wrapper. The invention provides a nozzle 42, directed to the edge of the radiating head adjacent to the outlet 43. The nozzle is connected to a tube 44 connected to a pressure source 45. A jet of air leaving the nozzle 42 prevents the accumulation of carbon particles on the outer edge of the radiating head 41. Instead of the nozzle 42, you can also use several nozzles or position an annular nozzle around the radiating head. The following embodiment of the invention is presented in FIG. 4, which shows a cut-out of the cross section of the device for electroperforation of paper tape 46. Insulators 48 and 49 are installed on frame 47 on both sides of the paper tape 46 to be perforated. On the insulators there are electrodes which in pairs form between an electrical connection. Electrode 50 c. Serves to connect to a high voltage source (not shown). The same connection electrode is located in the opposite insulator 49 on the opposite side of the device. The electrodes 51 are opened into the grooves 52 and 53, which are.
    On either side of the paper tape 46 to be perforated, two longitudinal channels are formed. The grooves 52 and 53 are connected by channels 54 and 55, as well as the openings 56, to a source of 57 shielding gas. The insulators 48 and 49 also have holes 5.8 and .59 connected to the source of protective gas Nozzles 60, emerging from holes 58 and 59, are oriented to the front surface of the electrodes 51 adjacent to the surface of the transition of spark discharges. The perforation process cannot, under the action of the gas jet coming out of the nozzles, accumulate on this edge and adversely affect the perforation. The shielding gas flow from the shielding gas source 57 diverts the carbon monoxide particles formed through the channels formed by the grooves 52 and 53 directly from the device.
