    The present invention relates to a vortex air nozzle for yarn spinning from staple fibers, comprising an outgoing pair of drawing rollers, next to which is located an inlet chamber for the formation of free tails of fibers, with decreasing flat cross-section and inner grooved channels, ending with a cylindrical part, connected to the outgoing twisting chamber, supplied with tangential channels for air feeding, wherein in the inlet chamber for the formation of the free tails of fibers. The grooved channels are laterally formed in a drawing plane and reach the cylindrical outgoing part, as in the inlet chamber enters part of the circumferential surface of the lower drawing roller, as the cylindrical outgoing part is enveloped by the outgoing twisting chamber, which tangential openings are concentrically formed above the said cylindrical outlet part. The advantages of the present invention are that a sufficiently large number of free tails is created, and a control is ensured, up to the achievement of the false twist, and the fibers are strongly twisted by a potential vortex.

    The invention relates to the textile industry and relates to a pneumatic twisting member of a device for producing yarn from staple fibers.
    A pneumatic twisting unit of a device for obtaining yarn from staple fibers is known, which includes a housing with notches for partially accommodating its rollers, having a slit-like feed channel located with an elongated cross-section side parallel to the rollers, installed in the exit zone of the fiber ribbon. an outlet pair and tapering in the direction towards its outlet part, made in the protrusion of the housing, located in a twisting chamber with tangential channels, N-; complete in the housing in the area of its protrusion and communicating with its annular cavity for supplying compressed air. (US patent No. 4489545, cl. B 02 G 1716, 1984).
    This twisting organ does not provide effective separation of the tips of the fibers from the fibrous ribbon as it moves in the slit-like feed channel and does not have an effective OE.

    it is squeezed by them when the fiber ribbon is twisted falsely with an air source in a twisting chamber, which reduces the quality of the yarn produced.
    The aim of the invention is to improve the quality of yarn.
    This goal is achieved by the fact that spline channels are made in the housing, located along the supply channel with two opposite sides of its elongate cross section distant from each other and tapering towards the output part of the supply channel, and the axes of the tangential channels of the torsion chamber are perpendicular the protrusion of the plane body, wherein the tangential channels are made in communication with the torsion chamber through an annular cavity made in the body concentric with its protrusion.
    The body is made of two parts connected to one another with the formation of a gap between them, with the supply channel located in one part of the body and the twisting chamber in the other part of it.
    On the part of the body with a torsion chamber there is an annular shoulder located in the gap between the parts of the case, while the tangential channels of the twist chamber are made in an annular shoulder.
    Figure 1 shows a pneumatic torsional body, a longitudinal section; figure 2 - supply channel with slotted channels, a horizontal longitudinal section; Fig. 3 shows a feed channel with slotted channels on the side of an exhaust pair of a stretching device of a device for producing yarn; figure 4 - torsional body, a cross-section in the zone of tangential channels.
    The pneumatic twisting member of the device for producing yarn 22 from staple fibers comprises a fixedly mounted in the exit zone of the fibrous ribbon 3 from the outlet pair of rollers 7 of a pulling device (not shown), a body made of two parts 11 and 13 connected to one another. connector part 14. In the part 13 of the cusp-55 of the cusp there are recesses for partial placement of the rollers 7 of the exhaust device pair, slit-shaped

    feed channel 1 and splined channels 2 located along it from the two outermost sides of its elongated cross section distant from each other. Feed channel 1 is located with the elongated side of the cross section parallel to the rollers 7 of the exhaust pair of the exhaust device and is narrowed towards its outlet part 5 located in the protrusion of the housing part 13. In front of the outlet part 5, the feed channel has a cylindrical section 18. Spline channels 2 are made tapering towards the outlet part 5 of the feed channel 1 at an angle V equal to 8-28 ° .fl
    In the other part 11 of the housing, there is a cylindrical twisting chamber 8 extending in the direction of the diverting rollers 21 in section 19 at an angle φ of -1 - 3 °.
    In the gap between parts 11 and 13 an annular bead 10 is placed, made on the part 11 of the body. In the annular shoulder 10 there are tangential channels 9 located in the region of the protrusion of the body part 13 with the output part 5 of the supply channel 1 and communicating on one side with the torsion chamber 8 through an annular cavity 12 which is concentric with the body protrusion. The axes of the tangential channels are located in a plane perpendicular to the protrusion of the body.
    On the other hand, the tangential channels 9 are connected to the annular cavity 15 between the housing parts 11 and 13 and their connecting element 14 connected via an opening 16 to a source of compressed air (not shown).
    A gasket-20 is installed in front of the exhaust pair of rollers 7 of the exhaust device. Between parts 11 and 13 of the housing seals 17 are placed.
    The torsional body works as follows.
    Worn out in an exhaust device and compacted in a fibrous tape sealer 20 a ribbon of 3 staple fibers at the exit of the clip 4 of an outlet pair of rollers 7 bends around the lower one on the arc 6

    on the arc b with an angle (X equal to 15 - 65 °, and enters the chute carriage 1.
    Air flow through tangential channels 9 around the ring
    The void cavity enters the torsion chamber 8, as a result of which air is sucked into the feed channel 1 due to the vacuum created in it from the atmosphere, passing through the spline channels 2 and facilitating the separation of its free fibers from the fiber ribbon; In the torsion chamber 8, the rotating air flow coming out of the tangential channels 9 is subjected to a false torsion of the fiber ribbon. When the ribbon is unwound, the free ends of its fibers are wrapped around it, as a result of which a yarn is formed, withdrawn from the torsion organ by diverting rollers 21.
    The presence of the slotted channels communicating with the supply channel facilitates the effective separation of the fiber ends of the fibrous ribbon as it moves along the supply channel, and the rotating air flow coming out of the tangential channels directed perpendicularly to the protrusion of the body of the torsion body and the tangential channels wrapping it with free ends of the fibers during e-unwinding, which contributes to improving the quality of the yarn.
