    Independently actuable underwinding clearers are mounted adjacent to those lower portions of the machine's spindle assemblies upon which yarn underwindings are placed preparatory to the formation of yarn packages upon the upper portions of the spindle assemblies. Upon actuation thereof during each cycle of package building operation of the textile machine, the clearers separate the lengths of yarn interconnecting the underwindings with the yarn packages undergoing formation upon the spindle assemblies. The clearers preferably are actuated sequentially and pneumatically. A preferred mode of actuation of the clearers is by blasts of air emitted from a mobile servicing apparatus, such as a conventional pneumatic traveling cleaner, during movement of the apparatus along the length of the textile machine.

    A textile machine with an annular spinning machine contains at least one row of spindles 1 mounted on a spindle bar 2 rotatably with respect to vertical axes in slot 3 by means of a braid pressed against the blocks of 5 spindles. Each spindle has a double-flange bushing 6 for forming a yarn 7, the upper flange 8 and the upper part 9 of which are knurled. A cartridge 10 with a yarn coiled on it is mounted above the sleeve 6 on the spindle, which is laid out along the cobs with the help of a ring 13 with a slider fixed on the ring bar 12.
    Each spindle on the spindle bar is equipped with a device for
    separating the cob from the body of the cob II, having an executive organ, which is a curved plate 14 with a rectangular flat surface 15 and two lateral flat surfaces 16 and 17 bent to one side and having a triangular shape. A separating edge 18 is made on the surface 17. The device has an executive body holder, which is an L-shaped rod 19 placed vertically with the lower end of the spindle bar 2 and fixed to it with the help of a washer and screw 20 passing through the hole in the spindle shelf timber.
    At the other end of the rod 19 there is a V-shaped 21, on which a plate is mounted with its slit-like opening 22 on the surface 15. And with the ability to rotate about a horizontal axis located parallel to the p d spindle
    The center of mass of the plate is located so that in the non-working position of the device the plate with its lower end 23 abuts against the shelf of the spindle beam.
    The machine has means for moving the plates into the zone of rotation of the cut 24 yarn connecting the reel 7 with the body of the cob 11. It is mounted on the machine for movement along a number of spindles by means of the carriage 25 and acting alternately on each plate or group of plates 14, surface 15 each of which is located opposite the means for moving them. This means is a down blower 26 (Fig. 1} or a device for picking 27 yarns (Fig. 2), which are equipped with a nozzle 28 located at the level of the plates 14. The blower has sleeves 29 and moves along the upper guides 30, and A device for picking is placed on the upper 31 and lower 32 guides with the possibility of reciprocating along them.
    The means for moving the plates can be made in the form of a common duct 33 connected to the air supply source 34, placed along the machine and having branches 35 according to the number of spindles, directly connected to the duct or grouped and connected to it via electromagnetic valves 36 and collector valves piping 37. The valves 36 are actuated in series from a common switch 38 (Fig. 8).
    A possible embodiment of the executive body of the device for separating the sub-wind in the form of a plate 39 of a triangular shape with two separating edges 40 and 41
    0 at the end. The plate through two rigidly fastened captives on it with the ends of curved rods 42 and 43 is installed along a number of spindles on the spindle beam 2. Free ends
    S rods are bent and fold out in the holes 44 of the beam with the possibility of rotation relative to it. The stopper of rotation of the plate 39 is a bent end 45 of a rod and an adjusting screw 46 on the end 47 of the rod 43, which abuts against a bar. ,
    Between the sleeve 6 and the metal ring 48 of the cartridge 10, the cob 11 may be placed one or two rings 49 with recesses 50 on the rim. Instead of the nozzle 28 on the device for conveying, a flexible rod 51 can be used, which is cantilevered and horizontally mounted on the cart at the level of the plates 39.
    In the off position, the plate 39 under the action of its mass is rejected
    5 from the spindle at an angle of 20 relative, but vertical and rests with its long edge 52 on the spindle beam.
    Textile machine works barely, blowing manner.
    During the operation of the machine, the yarn is wound onto the cob 11 rotating with the spindle by means of a ring plate moving back and forth along the spindles. After operating time, the annular plank is lowered to its lower position, as a result of which, in the upper part of the sleeve 6, a sub-winding 7 is formed, which is connected with the body of the cob P by the segment
    0 24 yarn, passing through the metal ring 48 of the cartridge, the ring 49 (11) and the upper flange of the sleeve 6.
    After replacing the bobbins with the cartridge heading and starting the machine for the next pick-off, it is necessary to remove the submotor from the spindles. For this, a blower moving along the machine 26 or a device for conveying
    27, when approaching the spindles, they alternately exert air flow to the plate H from their nozzle 28, causing it to rotate on the rod 19 and introduce its separation edge 18 into the rotation zone of the 2k yarn segment, as a result of which the yarn breaks off and separates from the cob (fig.Z). In the process of yarn breakage, the plate edge 18 may abut against the end face of the flange.
    8 of the sleeve 6, it is not advisable to fix the plate I in the working position due to the abutment. the lower edge of its middle part into the rod 19. A yarn break is preferable before cutting it in connection with the fact that in the latter case the ends of the yarn are broken, and this leads to an increase in the fluff rate on the machine and its contamination.
    After the break of the yarn, the turns of the winding are weakened due to the rotation of the spindle and gradually slide into the lower part of the sleeve 6, and then they are removed from the spindles.
    It is possible that several plates are moved to the working position at the same time, however, in this case an increase in the load on the spindles may occur, leading to a decrease in the frequency of their rotation.
    The nozzle 28 can continuously supply air flow in the direction of the plates or briefly at the moment the puff-blower or the tapering device approaches the corresponding spindle. Such operation of the nozzle can be achieved by means of electronically controlled valves or valves (not shown).
    When using the means for moving the plates (Fig. 8), the air is supplied sequentially to each or a group of plates by alternately turning on the electro-magnetic valves 36.
    In the embodiment of the device according to Figs. 9-11, when exposed to the air flow, the plate 39 is rotated by means of rods k2 and 3 and occupies a vertical position in which one of its separation edges 0 and M enters the rotation zone of the 2k yarn segment and breaks it. The stopper of the rotation of the plate is the bent end 5 of the rod 2 or the screw 6 on the rod 3 abutting against the spindle. If, instead of using a 2C nozzle, a flexible rod 51 is used, the latter acts as it moves along p springs on the inclined edge of the plate, causing it to turn in the direction of the spindle, bending to pass along the plate.
    The blower and blower pass several times.
    In the process of producing one pickup, so that in the event of a failed yarn on their first pass, an attempt to separate the coil from the cob can be repeated on subsequent passes, thus ensuring the reliability of the coil separation.
    The presence on the plate 39 of two edges makes it possible to use it for spindles with two opposite directions of rotation, which are necessary to communicate directly to the S or Z twist. The plate H, when the direction of rotation of the spindle is reversed, is placed together with the rod 19 on the opposite side of the spindle, with its slot-like hole for fitting onto the rod at the other end of the surface 15 and the separation edge is located on the side surface 16.
    The use of the invention makes it possible to efficiently and simply remove the sleeves from the spindles and ensures ease of maintenance of the machine during operation and during its installation.
