    The invention relates to the textile industry, in particular to methods of winding a package with yarn on a spinning machine and devices for their implementation.
    The purpose of the invention is to improve the quality of the winding, and reduce labor intensity.
    According to the method of winding with a yarn on a spinning machine fed to a rotatable package, the yarn is laid out by reciprocatingly moving the co-axially arranged yarn spreader and formed from the yarn after completing the formation of the package, the sleeve under the package is wrapped by lowering the section the level of the sleeve and the winding of several turns of yarn on it; in this case, the supply of yarn is stopped with a stretcher, and when lowering the section of yarn that runs on packing, to the level of the sleeve, see Pipeline turns of yarn from package by its rotation in the opposite direction and is fixed at the same rotational direction of the package underwinding coils by winding them on the sleeve.
    The incident section of the yarn is placed relative to the lower end of the sleeve stationary.

    FIG. 1 shows schematically an apparatus for carrying out the method, in the position of completing the formation of the package; in fig. 2 - the same, in the position of the beginning of the formation of the sub-band; in fig. 3 - the same, in the lowering position, incident on the packing of the area of the yarn; in fig. 4 - the same, in the position of the yarn rolling on the package at the level of the sleeve for reeling; in fig. 5 - the same, in the position of forming the winding on the sleeve; in fig. 6 - lower part of the spindle, section.
    The device comprises an exhaust device with an exhaust pair of rollers 1, mounted on spindle bar 2, drive spindle 3 with drive block 4 and holder 5 of package 6 and mounted spindle 3 coaxially with spindle with reciprocating movement along it, for example, in the form of a ring strap 7, on which is fixed a ring 8 with a slider 9, which is completely placed on it.
    Under the package holder 5, a ring 10 is fixed on the spindle for guiding the yarn 11, which has an annular shoulder 12 on the outer side surface and is made on the end face facing the holder 5 with a cavity 13 for accommodating the lower end of the package holder 5. Under the ring 10 on the spindle loosely installed sleeve 14 for winding, the upper end of which is located in the annular recess 15 of the ring 10. The outer surface 16 of the sleeve 14 has the shape of a truncated cone, facing the smaller base to the ring 10. The lower edges 17 of the ring 10 are made pointed for cutting the yarn 11.
    Spindle 3 is mounted for reverse rotation.
    The method is carried out as follows.
    The sliver of fiber from the spinning machine 1 of the spinning machine is twisted by a rotating spindle 3 into the yarn 11, which is wound onto the package b by folding the yarn along it with a reciprocatingly moving annular plank 7, thus forming the package 6.
    After the formation of the package 6 is completed, the yarn is stopped feeding with an exhauster, the spindle is stopped and the ring bar 7 is raised above the upper ring 18 of the package 6 and shifted relative to the package in the radial direction, while the spindle is rotated in the direction opposite to its rotation package formation 6. Then form from
    the yarn on the sleeve 14 by lowering the section 19 of the yarn incident on the package to the level of the sleeve 14 and winding the turns of the 20 yarn from the package due to its rotation
    spindle in the direction of unwinding the package. When rotated together with the wrapping of the yarns wound from it, it is brought into contact with the annular protrusion 12 of the sleeve 14 and is wound in the form of several turns onto the fixed sleeve 14, which hold it with its annular collar 21.
    The yarn section 19 incident on the package 6 can be lowered to the level of the sleeve 14 by means of a rod 22 installed
    5 next to the spindle 3 with the possibility of movement parallel to its axis (Fig. 5).
    When removing the package from the spindle, the section of yarn between the package and the coil turns is cut by the sharp edges of the ring 17
    0 10.
    Placing the lower end of the package holder 5 in the cavity 13 of the ring 10 reduces the distance between the first turns of yarn on the package and the annular shoulder 12 of the ring.
    When resuming the formation of the next package on the spindle, the coils of the winding unwind on the sleeve and automatically come off of it, which reduces the labor intensity
    0 when removing the tack from the spindle. Furthermore, the method and apparatus allow winding any necessary number of turns of the winding on the sleeve with a constant predetermined tension of the yarn throughout the winding section, in:
    5 including thin and fragile yarn, and receive packages with a short free end of yarn on it after it is removed from the spindle due to the exclusion of yarn wraps on the package when lowering the spreader to the level of the spindle sleeve, which improves the quality of winding.
    The proposed method and device can be used not only on the ring 5 of the spinning machines, but also on the cap and other types of spinning machines.
