    The individual spinning rings of a ring-spinning or yarn-doubling machine frame, which are supported via a pneumatic cushion upon the respective ring holder and upon which a traveler is adapted to orbit, have compressed air introduced initially to support the rings. The compressed-air injection is interrupted when the rings reach a rotational speed enabling them to draw in the air for the cushion (self-sustaining airborne support cushion). Manually operated valves individual to each ring are in respective branch ducts and are provided for individual startup while a central control is provided for all of the rings.

    The invention relates to textile industry and relates to ring spinning and twisting machines, namely, devices for launching rings with aerodynamic supports. It is known a device for launching rings with aerodynamic 1 and supports on annular spinning and twisting machines, which contain nozzles connected to a compressed air source for supplying compressed air to the supports of the rings when they are started. One drawback of this device is that from the rings of the machine, a stop is required to restart all. rings after the elimination of a thread break on one of them, which reduces productivity. In the case of supplying compressed air to the working rings of the machine with one of them, after the thread breakage is eliminated, there is a high energy consumption and the negative effect of changing the friction in the bearings of the rotating rings on their work with such an air supply. The aim of the invention is to increase productivity by starting a separate ring while eliminating thread breaks without stopping the machine. This goal is achieved by the fact that the device for launching rings with aerodynamic supports on annular spinning and torsion rings, soda pipes connected to a source of compressed air for supplying compressed ground air to the supports of the rings, when they start, contains a pipeline located along the row rings and connected to a source of compressed air, and several controlled valves located between the source of compressed air and supports rings, and the nozzles are connected to the pipeline. At the same time, one valve is connected to each branch pipe support ring. one valve is connected to the branch pipes of the supports of the group of rings. In addition, the device contains an additional pipeline connected to a source of compressed air by means of an adjustable valve and to the supports of the rings. The device comprises means for actuating individual gates having a time relay.
    1 shows a diagram of the device, top view; 2 is the same, the transverse ceweaHef of FIG. 3 is an embodiment of the device; Fig. 4 shows the means for actuating the valves; Fig. 5 is a graph showing the change in the rotation chart of the ring and believe it when the thread is clipped.
    A device for starting the rings 1, for example, the ring spinning machine contains a pipeline 2 located along a row of rings 1 placed on the ring plate 3 of the machine and connected to a source of compressed air having an electric motor 4 and a compressor 5. Pipe 2 by nozzles 6 is connected to ring stops , we imagine the gaps 7 between the rings 1 and the bar 3.
    The device has several controllable valves 8 placed between the compressed air source and onopaNoi rings, with one valve 8 connected to each nozzle 6 or ring 1 (fig-1) or group of rings (Fig. 3).
    In an embodiment of the device, it additionally contains a conduit 9 located along the annular strip 3 and connected by means of an adjustable valve 10 to a source of compressed air and by means of nozzles 11 to the supports of the rings 1.
    The switches 8 are turned on by pressing the spring-loaded button 12 on the arm or by means of electromagnets 13 electrically connected to the switch 14 controlling all the valves together and separately (FIG. 3).
    To eliminate the need for constant action, for example, manually on the valves, when a thread breakage is eliminated, a device is provided in the device for actuating individual valves, having a time relay 15, connecting the valve solenoid 13 to a voltage source when the button 12 is pressed, is not shown) . A variant of equipment and electromagnet13 time relay is possible.
    When MaijHHH is put into operation after the valve 10 is turned on, the compressed air is supplied through the pipeline 9 and the nozzles 11 to the ring supports, filling the gaps with a mexda with rings and a ring bar and creating & thereby air support rings. When the spindles rotate, the yarns rotate and the rings, which, after reaching a certain rotational frequency, themselves contribute to the creation of aerodynamic supports by forming air flows by the supporting surfaces of the 16 rings. As a result, there is no need to force the supply of compressed air through the nozzles.
    11, for which the valve 10 is turned off. The frequency of rotation of the rings in the course of the operation of the shaft is somewhat less than the frequency of rotation of the rotors due to the lagging of the slider, which is necessary when winding the thread on the cob (Fig. 3).
    If the thread breaks at time t. on any one ring of the machine, the frequency of rotation of the ring decreases, and at a certain value its n ring loses the ability to create a support for itself and, due to the friction of the ring bar, stops quickly. To eliminate the thread break, the spindle is also stopped. In a period of time, which may have any duration, to eliminate a thread break, then press the button corresponding to this ring valve 8 manually or using an electromagnet 13 when the switch 14 is closed and the compressed air from the pipeline 2 flows to the ring support (position 1B ).
    At the moment t.4, the spindle is started up, which causes the ring to rotate through the thread. After reaching the spindle and, accordingly, the operating mode ring in the center1 t5, the valve 8 is turned off and that message is supplied to the ring of compressed air. The time interval tj-tj corresponds to the time of activation and shutdown of time relay 15.
    When one valve 8 is connected to a group of rings, the air from pipeline 2 flows directly to all the rings of this group (FIG. 3). Such an embodiment of the devices causes a decrease in the number of valves installed on the machine.
    This device allows the launching of a separate ring (or a group of rings) at the elimination of a thread break without stopping the entire machine, which improves its performance. In addition, a separate start-up of each ring eliminates the adverse effect of the change of friction in the supports of the rotating rings on their operation when compressed air is supplied to them at the time of the elimination of a break on one of the rings.
