    An apparatus for the production of tubes, especially tubes for Russian-type cigarettes, is described, having a mandrel (32) for forming the tube (44) and air intake ducts (52, 54) to form an air cushion for the tube. The mandrel (32) also forms an inner support for the tube (44), as far as a trimmer (56), and is provided with a chamfered end surface (60) which is situated close to the path of the blade. The mandrel (32) can be retracted (via the device 62, 64) in order to permit the operation of a strand breaker during start-up. At least one longitudinal groove (68) can be provided in the mandrel (132), in order to receive a section (70, 72) of the tube which forms a spark trap. <IMAGE>

I; Fig 9 is a modified mandrel section.
    The device comprises means for supplying the inner paper or cardboard strip 1 and the outer paper or cardboard strip 2. The means for feeding the strips of material includes guide rollers 3 and 4. The device includes a means 5 for applying glue to one of the edges of the outer strip 2 The means for forming the strips of the continuous tube comprises an endless conveyor belt 6 which passes around the end roller 7 and receives the outer strip 2 and the guides 8. A means for gluing is mounted above the conveyor belt 6 Olos 1 and 2, wherein the compound is an endless belt 9 with a heating element 10. After infinite. The final tape 6 contains bending plates 11 of a TJ-shaped section and a support 12 with a cylindrical section with a channel 13 and a device for supplying fluid into the gap between the support 12 and the material strip, which are radial transverse openings 14 arranged at an angle to one another. connections of the channel with the surface of the support, through which air is supplied into the narrow gap between the strips 1 and 2 or formed by the tube and the support 12. Provision is made for a device 15 for applying glue to the strip 2 of material. On the conveyor belt 6 there is a means for gluing the edges of the strips 1 and 2 in the form of an endless belt 16 with a heating element 17. Behind the guides 8 there is a driving roller 18 having a corresponding surface (for example, a rolled surface) and cooperating with the driving roller 19 of the belt 6 for take off

    tubes with guides 8 and transporting them to the means for cutting in the form of a knife 20 and the supporting surface 21. Between the means for cutting the tube into separate segments and a support there is a tube deflecting means 22, mounted for movement across the device. The support 12 extends to the means for cutting the tube and serves as a support for the tube when it is cut.
    The end of the support 1 2 is cut at an angle and has a shape corresponding to the transverse path of movement of the means for cutting the tube during its operation. The device comprises means for moving the support 12 in the longitudinal direction, including the guide 23 and the power cylinder 24. The additional roller 25 with the knife 26 is a means for making cuts on the inner lane 1, and the support may have means for mixing the cuts inside the tube being formed, grooves 27, the angular position of which corresponds to the angular position of the folded petals 28, formed during the formation of the notches by the knife 26 so that these petals remain inward during the formation of tr CHB.
    The inner lane 1 passes over the guide roller 3 and is superimposed on the outer lane 2 so that the lanes are slightly displaced relative to each other in the transverse direction (Fig. 3). The inner and outer lane 1 and 2 are transported by the belt 6 and the roller 4, slightly compressing them and us-. mounted opposite the end roller 7 of the forming tape.
    Behind the roller 4 there is an endless belt 9, heated by element 10, as a result of which the inner and outer strips 1 and 2 are glued together. Next, the inner and outer strips are transported by the forming tape 6 to the zone where the bending plates 11 are located, where they are formed in a U-shaped section in a known manner, after which the strips 1 and 2 overlap each other and form a tube. As shown in FIG. 1 and 4, the strips 1 and 2, as well as the forming tape 6, are initially wrapped around a portion of the support 12 having a U-shaped lower end. The guides 8 and the cylindrical part of the support 12 interact to successively give the strips 1 and 2 of tubular shape to FIG. five). The inner upward edge of the outer strip 2 is provided with a strip or drops of glue applied by the device 15. Further downstream (Fig. 6), where the guides 8 have almost completed the formation of the tube from the inner and outer strips 1 and 2, they pass under another heated tape 16, heated element 17, and glued to the tube. Behind the guides 8 the fiber tube interacts with
    the last drive roller io having a corresponding (e.g., knurled) surface, which in turn interacts with the drive roller 19 of the forming tape 6 to lift the tube and transport it further,
    After the shaping is completed, the tube is cut into separate sections with the help of the knife 20 and the supporting surface 21. During the cutting of the tube, the knife 20 and the supporting surface 21 are fed in the direction of movement of the tube with the same speed as it. The cutting edge of the knife 20 moves along an inclined path relative to the end of the support 12, the end of which is cut at an angle so that it is very close to the trajectory of the knife during the cutting of the tube (at the optimum or normal speed of the machine). the tube during cutting and together with the support surface 21 provides a clean cut of the tube.
    The structure of the finished tube is shown in FIG. 7. There are other possible variants of the design of the tube5 performed by the proposed device. In particular, despite the fact that both lanes 1 and 2 are glued together end-to-end, it is possible for both seams or one of them to overlap. This is preferable for outer band 2, since the overwrap is relatively thin and the seam must be strong.
    When the device is initially turned on, the tube may form incorrectly: for example, a strip of glue may be applied incorrectly, or the glue may harden ahead of time. In devices for the manufacture of a continuous tube, it is usual to retract incorrectly measured

    the tube and feed the cutting device only a properly shaped tube / after a short time after the start). The tube is deflected directly in front of the cutting device with a device that is capable of cutting the end inserted into the cutting device. In order for this device to function, the support 12 is retracted a sufficient distance so that the device to be installed can process the tube in front of the cutting device. For this, the support 12 is made movable along the guide 23 under the influence of the piston of the power cylinder 24. Thus, the leading end of the support 12 can be removed for a sufficient distance to allow the tube to deflect and cut. A flexible air supply tube (not shown) can connect the channels 13 in the support 12 with an air source in all
    5 positions of support. The piston of the cylinder 24 may gradually feed the support 12 back to the position shown in the drawings after the initial cutting of the tube.
    In cigarette mouthpieces, a trap for fire is usually made. In the proposed device, the support 12 can be modified so as to have slots 27 allowing the petal or edge of the strip to pass, from which a trap is formed about the section of the modified support 12 fitted with the air channel 13 and the radial holes 14 and, moreover, the longitudinal grooves 27 for accommodating the petals 28 performed by the roller 25 and the knife 26. At least one of the grooves 27 can be adapted to accommodate the edge g of the internal field wasps, which forms a little one, either alone or in combination with petals 28.
    The proposed device improves the quality of the manufactured tubes by controlling the size and shape of the tubes by using a support.
