    The nozzles are formed by the end portion 42 of the nozzle 18 that faces the nozzle 19 and is mounted with the possibility of longitudinal movement in the housing and firmly pressing its end face against the end face of the nozzle 19 placed in the housing 17 stationary. In the end parts of both nozzles facing each other, grooves 43 are made in which a compression spring 44 is placed to return the nozzle 18 to its initial working position, fixed by a screw 45 screwed into the threaded hole of the housing 17 and placed at its end in the longitudinal groove 46 on the nozzle 18 The nozzle 18 has sealing rings 47 placed in the housing with the length of the sides of the annular recess 26 and located on the bottom end of the sealing ring 48. The screw 45 is positioned relative to the recess 46 of the nozzle 18 in such a way that it does not restrict Place this nozzle in the direction of the nozzle 1-9 to allow the ends of the nozzles to be firmly pressed against each other, between which a sealing ring can be placed.
    The suction tube 30 is mounted to move in the direction towards the lower end of the torsion body after it has been moved to the off position, pressed against it and acting on the nozzle 18 to move it upwards.
    A variant of the flap is possible in the form of a spring-loaded spring 49 of the sleeve 50, mounted on the lower end of the body of the torsion body with the possibility of axial movement relative to it and blocking the slot of the body 21 and the gap 20 between the nozzles (Fig. 5). A ring 51 is mounted at the upper end of the sleeve 50, which, when the sleeve 50 moves, presses up against the ring collar 52 of the housing located above its slot 21 and having an annular seal 53 arranged in the annular recess. Compression spring 49 is placed between the ring collar 54 of the sleeve and the annular collar 55 on the housing 17.
    The device works as follows.
    The fibrous tape or roving 14 is thinned in the exhaust device 1, the exit from which the fibrous ribbon is extended through a pneumatic twisting member 2, into the nozzles 18 and 19 of which compressed air is fed through the openings 28 and 29. In the channel 24 of the nozzle 18, the free tips of the fibers of the fiber ribbon are wrapped around it with air flow, and in the channel 25 of the nozzle 19 the air flow performs a false twisting of the fiber ribbon, in which the fiber tips penetrate the core of the ribbon, thus ensuring that the formed 5 is imparted strength. The formed yarn 5 by a pair of diverting rollers 6 is led out of the twisting unit 2 and is fed to a winding unit 4, where the yarn is wound on the package 6 (Fig. 1).
    When a yarn is broken by a signal, a sensor (not shown) triggers a medium 15 to clamp a fiber tape or a roast in a stretcher, causing it to break and a piece separated from it is picked up by a suction element (not shown) to prevent it from falling into a torsional organ and slaughtering it.
    For picking the yarn off, the compressed air supply to the torsion body is turned off and the electromagnet 36 is turned on, which turns the lever 32 on axis 33 through the t 34 and switches the torsion body from the working position A, in which it is fixed by the spring 37 and the stop 38, to position B and pressing the body 17 of the torsional body to the valve 31 (Fig. 1 and 2). When this valve 31 closes the slot 21 in the housing 17 and the gap 20 between the nozzles, hermetically isolate their channels 24 and 25 from the atmosphere. The lower end 56 of the nozzle 18 is positioned above the suction tube 30, as a result of which a vacuum is created in the channels 24 and 25 of the nozzles 18 and 19, ensuring that the nozzle 19 led to the upper end 57 is caught and the yarn is rolled up from the package 6

    tilting the body and putting it into the suction tube 30. After that, the winding of the yarn from the package is stopped, the electromagnet 36 is turned off, and the torsion organ is returned to its initial working position A by the spring 37 up to the stop 38. Then, the roving 14 is released from the clamp
    0 the device, its thinning in it and the supply of compressed air to the nozzles of the torsional organ are resumed, and the ribbon coming out of the fiber device is connected to the end of the yarn and accorded to it, after which the yarn process is repeated.
    In an embodiment of the device according to FIG. 3, when the damper actuator is activated by the signal from the breakage yarn sensor, the flap 31 rotates on the axis 33 until it contacts the body of the torsion body, closing its slot 21, and further rotation of the flap in the same direction causes the rotation of the torsion body on the axis 33 in the same direction working position A to position B as far as it will go 58 to the zone of the suction tube 30. Position B can be determined by the magnitude of the stroke associated with the drive back-. slips of a tee 39. After posting the end of the yarn through the torsion body into the suction tube 30, the flap actuator turns it in the opposite direction
    5, while the torsion bar remains pressed to the flap by the spring 37 until the arm 40 of the lever 32 interacts with the stop 41, which determines the working position A of the torsional body. The flap is pulled back by the thrust 39 of the drive from the torsion bar to its initial position.
    The valve at the base to the torsion organ can be used as a means for stopping the supply of compressed air to the holes 28 and 29 of the torsion organ by shutting them off.
    When installing the nozzle 18 with a potential for longitudinal movement according to FIG. 4 and 5 after transferring the torsion organ from position A (FIG. 4) to position B (FIG. 5), the suction tube 30 comes from the bottom end 56 of the nozzle 18, which acts on the nozzle 18 and moves it up to tightly clamping its top end facing the lower end of the nozzle 19, as a result of which the gap between the nozzles is eliminated and the end portion 42 of the nozzle 18 closes the slot 21 in the housing 17 and thereby isolates the nozzle channels 24 and 25 from the atmosphere.
    In the case of a valve in the form of a sleeve according to FIG. 6, it also moves upward along the body 17 of the torsional organ with a suction tube 30 until the ring 51 on the sleeve is pressed against the ring sealer 52, as a result of which the slot 21 in the body 17 overlaps the sleeve.
    An element of the unit for feeding the yarn ring from the package to the twisting member (not shown) can be used as a means for moving the sleeve.
    It is possible to install both nozzles with the possibility of longitudinal movement towards one another or the placement of two spring-loaded bushings at both ends of the torsion body.
    The body of the torsional organ can be mounted directly on the axis 33 with the possibility of rotation relative to it or it can be moved in the rocker rail (not shown).
    Covering the gap between the nozzles using a damper allows you to create a small vacuum in the channels through a small vacuum created in the suction tube, which is sufficient to reliably charge the end to the torsion body and pass it through the nozzles, thereby reducing energy consumption.
