    A device for joining together two ends of a yarn in order to recreate the initial structure of the yarn comprises two heads provided with radial slots and fixed to rods which are rotatable in order to take up the yarn by means of the slots and to wind the yarn about the rods. The free ends of the yarns are untwisted and subjected to electrostatic fields created between the heads and an annular electrode. Rotating the heads in the opposite direction then causes the yarns to unwind from the rods and the fibres of the two ends of the yarn to twist together, the yarn then being released.

    The fixture for fixing the ends of the threads contains two suction nozzles, each of which has means for cutting the thread, and the spindle supports are driven to rotate about an axis perpendicular to the axis of the spindles and position the rods along the suction nozzles for gripping the ends of the threads. The device contains an annular electrode mounted / connected between the rods coaxially with it and connected to a source of electrostatic charges. The device contains a pair of electrodes rigidly connected to the rods and installed with the possibility of positioning between the rods when they are coaxially mounted and the working surfaces of the electrodes are one against another along the axis of the rods. FIG. 1 shows the device, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a graph of the cycle of the device; in fig. 6 embodiment of the device, an axonometric projection; .on FIG. 7 is an embodiment of the implementation of individual elements of the device according to FIG. 6. The device comprises a frame with a base 1, two side walls 2 and 3, and transverse walls 4-7. Between the walls k and 5, a shaft 8 is installed with the cams 9-13 cooperating with the pushers fixed on it, which are connected to the corresponding control valves (not shown). The cam 9 is designed to control the operation of the electropneumatic switch 18, the cams 10-12 to control the power cylinders 19-21, and the cam 13 the two-arm lever 22 pressed against the ends to the two-arm levers 23 and. At the end of the shaft 8, a gear wheel 25 is installed, which is engaged with the rack rail 26 connected to the rod 27 of the dual-action power cylinder 19 (Fig.). A rake 28 is connected to the power cylinder 20, with which the gear 29 of the reducer is fixed, which contains the gear pair 30 and 31. The gear 31 is mounted on the shaft 32 mounted in the walls and carrying on the opposite end the bevel gear 33- of the walls 6 and 7 parallel to shaft 32, shaft 3 is mounted. Lips 32 and 3 pass through sleeves 5 and 36 mounted in wall 7 rotatably and bearing supports 37 and 38 at the ends. Spindles in the form of rods 39 and 0 are placed in the supports for winding on them tl and 2 threads , by means of bevel gear pairs 33, and 4t, and belt transmission 46 are kinematically connected to each other, and have the ability to rotate in opposite directions. Bevel gears 43. and D5 are placed on the rods, and the gear wheel kk is located at the end of the shaft 3. The coupling 36 has a gear wheel kj, which engages with the gear rack 8 connected to the power cylinder rod 21. On the coupling 36 it is pivotally mounted t ha E, pivotally connected to the other end with a crank 50, made in one piece with the coupling 35. The rods 39 and 0 are installed in the supports with the possibility of axial displacement in them and through the springs 51 the ends 52 and 53 are pressed to the levers 23 and 2). At the ends of the rods facing one another there are grips of the ends of the threads 41 and 42, which are hemispherical heads 54 and 55 with radial slits 5b and 57 for the ends of the threads. Both supports 37 and 38 are electrically insulated and have the ability to be connected to the terminals of the electrostatic charge source 58. The device contains a device for fixing the ends of the connected threads, having two suction nozzles 59 and 60 installed in the base 1 of the frame and connected to an air suction source (not shown). Each suction nozzle has means for cutting the thread, which is scissors 61, which are made double, placed in the groove 62 of the base and connected to the rail 48 by lever 63 (Fig. 1). At the ends of the pipes 59 and 60 are made combing teeth 64 (Fig. 2). . Between the rods, an annular electrode B5 is placed coaxially by means of a lever 66 on an insulated support 67 and connected by an end of the lever 66 to a cam 13. To connect the ends of the threads, each of them is inserted into a suction 5 connection in which a certain length of the end of the thread is held. In this case, the rods with supports are in the position shown in FIG. 2 by dash-dotted lines, with heads 5 and 55 facing the nozzles. Due to the air generated by the suction flows in the tension pipe, the threads are pressed to the heads. When the power cylinder 20 is turned on, the gear bar 28 is moved, and the gear wheel 29 of the gearbox starts to rotate from it and the shaft 32 with gear 33 and rotation gear 43 and; rod 39 with a head. The rotation of the shaft 32 through the belt transmission C6 is transmitted to the shaft 3 and the kQ shaft with a head 55. When the heads are turned, the threads fall into their radial slots 56 and 57, are caught by the heads and pushed onto the rods. The rods are rotated from in opposite directions, with each thread being wound onto the rod in the direction coinciding with the direction of twisting it. The number of revolutions of the rods is selected depending on the twist, which is connected to the connected ends of the filaments for their binding. The power cylinder 21 is then turned on, setting in motion a toothed rail ib, designed in such a way that it does not immediately engage with the toothed wheel. At this time, shears B1 are driven, which cut the ends of the thread, after which the rail 8 engages with the wheel, which turns the coupling 36 and through the connecting rod 49 and the crank 50 - the coupling 35. Turning the sleeves causes a turning 90 ° of both supports 37 and 38 with rods in opposite directions until coaxially aligned with each other. In this case, the ends of the threads are removed from the suction nozzles and are combed by the teeth 6k. After that, the switch 18 controlled by the cam 9 and the pusher connects the heads 5 and 55 to the brush 58 of electrostatic charges, with the heads becoming electrodes of opposite polarity signs. Each thread turns out to be charged by charging the head and is attracted by the adjacent head, and an annular electrode 65 connected to the device’s mass. Then, the corresponding polarities of the head electrodes are inverted several times by means of a switch 18 to alternately open and close the fibers of both ends of the threads and entangle them. between themselves. Then the electrode B5 is disconnected from the mass of the device and the fibers are no longer attracted to it, after which the cam 13 moves the double-arm lever 22, and the springs 51 move the heads apart from each other to tension the tangled fibers of the ends of the threads and parallel their arrangement. Next, the electrostatic field is interrupted by the cam 9 and the pusher 14 and the power cylinder 20 returns the rack rail 28 to its original position, the resulting rods begin to rotate in the opposite direction and the connected thread is wound from them, while the fibers twist in the place of their connection. After the thread is completely unwound and the fibers are firmly joined, it comes out of the head slots due to its tension. The process of connecting the ends of the threads is over. In the graph (FIG. 5), the cycle of operation of the device of the line s is the position of the ram 19; line 5 - control of the position of the rods 39 by means of the cam 13 of the levers 23 and line B - the power of the power cylinder 21, the line r and the application of potentials to the rods 39 and 40, the line e the position of the power cylinder 20 and the line of the ring electrode 65.. The time tg corresponds to the activation of the FORCE cylinder 19 driving the cam shaft 8, and the power cylinder 20 controlling the rotation of the rods. It was at this time that the ends of the threads inserted into the suction nozzles entered the radial slots of the heads of the rods. At time t, | the rods stop rotating and voltage is applied to the heads from the source of electrostatic charges (lines & and E), and the electrode 65 is connected to the device mass (line). After connecting the rods to the potentials, the toothed rack and double scissors 61 begin to move with subsequent rotation of the supports 37 and 38 until the moment t, accompanied by the combing of the ends of the threads (line at At time t, the rods approach by means of the cam 13 and the levers 23 and 2k (line 8) until the time tf, starting from which and until the moment of polarity of the rods P therefore, the lines (g and E) are inverted. At time t, electrode 65 is isolated from the mass of the device (line g). At time 13 and up to t, the rods are separated from one another (line B), and at time tj., the rods begin to rotate in the opposite direction for twisting the fibers of both ends until tj which means the end of the cycle of operation of the device. In the period from 13, the executive bodies of the device return to their original position. A variant of performing the device with two electrodes 68 rigidly connected with rods 39 and 0 and installed with the possibility of positioning between the rods with their axial installation and placing the working surfaces of the electrodes against each other along the axis of the rods is possible (Fig. 6 and 7). These electrodes are connected to an electrostatic charge source 58 and are intended to attract and unwind the spun ends of the threads. To do this, they are covered with a thin layer of dielectric material with a thickness of 0.2 mm, for example, α-teflon. Through this material, the electrode attracts a thread charged with a potential opposite to the potential of the electrode, but retaining its potential due to the presence of a dielectric. Therefore, in this embodiment, the fiber devices are not located around the circumference, but are pressed to the surface of the respective electrodes 68 and B9. Each head 5 and 55 has knives 70 and 71, respectively, mounted on support 37 and 38. The fixed knives 72 and 73 are mounted on the knife movement path. 70 and 71, while the knives of each pair are located on both sides of each thread tensioned between the two suction ports 7, 75 and 76, 77, respectively. At the electrodes, the injection nozzles 78 and 79 are placed in such a way that the air flows coming out of them pass 8 mainly along the filaments. which are wound on the rods 39 and 40 in the direction ensuring their unwinding between the heads 5 and 55 and the nozzles 7 and 7b. The threads leaving the nozzles 78 and 79 comb the threads, freeing the fibers in the section between the heads and the pipes 7 and 76. These fibers are attracted to the electrodes 68 and 69. After the rods with the electrodes are rotated one to another, the ends of the threads are clamped between the electrodes and connected by twisting when the rods are rotated in the reverse winding direction. The faces facing one another of the electrodes may have a curved shape to ensure the tension of the ends of the filament 2 (Fig. 7). The proposed design of the device ensures its reliable operation and allows for a reliable connection of the ends of the threads with the tensile strength of the connected section, which is up to 80% of the initial strength of the threads with the simplicity of its design and maintenance. The first embodiment of the device is intended for thin and rigid fibers, and the second for more rigid and difficult electrified fibers. Claim 1.
