    The invention is from the textile industry and concerns methods for preparing the yarns for joining them. A known method of preparing the end of the thread for connecting with the end of the WITNDUA consists of fixing the nifi, unwinding its free end and separating the loose EniFtix Cl 7 fibers from it. In order to obtain a solid connection of the ends of the strands, it is necessary to separate the ends to separate fibers and the size of the fibers of one strand among the fibers con another thread .. However, the known method allows the fiber to be divided only for a certain type of thread, namely, obtained on circular 11dr; dilnye: machines with a structure, the length of which is parallel to wives one to another and twisted. In the yarns obtained on ringless spinning machines, the fibers are non-parallel to each other, with the result that when the ends of such a twist are broken, the fibers are not separated from each other and therefore do not allow a strong connection of such threads to one another. their rupture occurs, which also adversely affects the quality of the connection. . The aim of the invention is to improve the quality of the preparation of the end of the filaments of various types by eliminating the breaking of the fibers. The goal is achieved by agreeing on the method of preparing the end of the thread dp of the joint with the end of the other thread, closing the wind in fastening the thread, unwinding its free end and separating it from the end of the thread of the unreliable fiber by traversing it with the help of an air flow directed along the thread in the direction opposite to the place of fixing it, and communicating the end of the thread of the thread and the direction perpendicular to the OM on the movement of the air flow. At the end of the thread, it is reported that it is mediocre, and you can install a jteWHoft flexible plate. Vibration end of the thread reported frequency of 500-2000 Hz. FIG. 1 shows an apparatus for carrying out the method; in fig. 2A-A in FIG. one; in fig. 3 embodiment of the device; in fig. 4 shows section B-B in FIG. 3. A device for preparing the ends of the coefficients e a) x of the threads 1 contains two spindles 2 mounted on a rack 3 in the supports 4 with the possibility of rotation together with them relative to the axes perpendicular to the spindles. At the end of each spindle, a head 5 is fixed with a radial slot 6 for gripping the end of the thread. From the heads of the spindles, the suction nozzles 7 are installed, the end section of each of which is made of two parts 8 and 9, interconnected by screws 10 (Fig. 2). Inside each nozzle, a plate 11 about 0.25 mm thick, made of rubber, is flexibly mounted. The plates are rigidly connected to the mounting bracket 12, sandwiched between the parts 8 and 9 of the nozzle, and forming a T-shaped profile with the plate. Plates are located along. nozzles that are made rectangular or square in this part to allow the plates to strike against two opposite walls of the nozzle. A crest 13 is fixed at the inlet of each nozzle and a radial hole 14 is made in part 8 of the nozzle. In the middle part of the nozzle there is a pair of knives 15 and 16 with holes 17 and 18 for the passage of the ends of the threads. The knife 16 is fixed and the knife 15 is able to move relative to it. Both nozzles are connected to a vacuum source 19. Both preparations for wx to the interconnection of the ends of the filaments are introduced into the corresponding nozzle and retained in it due to the created source 19 of the air dilution. After placing the ends of the threads of a certain length in the nozzles and in the slots of the heads 6, the spindle B is turned in the direction opposite to the thread twist so that several turns of the thread are wound on the spindle, thus fixing the threads on the spindles. Due to the presence of bending in the nozzles below the knives when the spindles rotate, the ends of the threads located in the nozzles unwind. Then after stopping
    the spindles cut with knives the ends of the threads at the level of the holes 18.
    Then, by increasing the vacuum of the air in the nozzles, the flexible plates 11 are vibrated and, using them, vibrate the ends of the filaments located in the nozzles. The beating of the plates against the ends of the filaments in the direction perpendicular to the direction of movement of the air flow sucked from the nozzles causes the filaments of the filaments to separate, and separating the filaments from the ends of the spindles of the filaments without breaking them is accomplished by tensioning them with an air flow moving along each piece end of the thread in the direction opposite to the place of its fastening. Vibrating free end of the thread in the socket contributes to the reduction of friction between the fibers and the possibility of separating loose fibers n from the end of the thread by the air flow. At the end of the thread, only the fibers of the thread are fastened by winding on the spindle.
    The ends of the threads prepared in this way for one second can then be interconnected by overlapping one another with rotation of the spindles relative to perpendicular axes.
    In an embodiment of the device for carrying out the method (FIGS. 3 and 4), the spindle 20 (the second spindle similar to it is not shown) is also installed in the support 21 for rotation around its axis and relative to its perpendicular axis. The support 21 is rigidly connected to a hollow shaft 22 connected by means of a rod 23 radially fixed thereto with a regulating screw 24. Inside the hollow shaft 22 there is a shaft 25 which carries a bevel gear 26 at the end that meshes with a bevel gear 27 mounted on the end of the spindle 20. At its opposite end, the spindle has a head 28 with a radial slit 29.
    A support 30 is fixed to a strap 30 with a chute 31 and an air distribution chamber 32, to which a tube 33 is connected, which connects the chamber with a source of compressed air 34. The chamber 32 has, at the level of the chute 31, an outward opening 35 formed by the sponge 36 and forming airflow along the surface of the chute. The bypass channel 37 of the chamber 32 is connected to the bore 38, in which a cone 39 is mounted, the top of which is located near the bottom of the groove and the axis of rotation is perpendicular to the bypass channel 37.
    A hollow shaft 40 is connected coaxially to shaft 22; the shaft 41 is radially fixed on it with a rod of an adjusting screw 42. The shaft 40 passes through a hole in the rack 43 and has a possibility of rotation relative to the shaft 22. A second rod 44 is radially fixed on the shaft 40, at the end i oToporo a locking pin 45 is mounted, connected to a frame 46 on which a second finger 47 is fastened, placed in the hole of the rod 48 parallel to the rod 44 and hinged at the end of the rod 49 radially mounted on the shaft 40. These rods form a parallel ogrammnSh mechanism for moving the frame 46.
    Frame 46 carries a 0.25 mm thick natural rubber membrane 50 with a longitudinal slit 51 and two transverse slits 52, which delimit two tabs 53, and the longitudinal edges of KOToi% ix pry1 “1 show one another. This frame can occupy two positions relative to the support 21, controlled by the adjusting screw 42. In the off position, the frame is removed from the bar 30 (shown by dash-dashed lines in Fig. 3), and in the working position the frame pushes to the bar and to the chute. . The two suction tubes 54 and 55, connected to the vacuum supply source 56, are located on two opposite sides of the support 21 and serve to tension the filament 57 after it has been laid in the chute 30 when the frame 46 is retracted from the bar.
    After placing the thread in the radial slot of the spindle head, it is rotated with the help of shaft 25 and gears 26 and 27; thereby winding several turns of the thread on the spindle. The spindle is rotated in the direction in which the end of the thread in the section between the spindle head and the tube 55 is unwound.
    Then, by means of a parallelogram mechanism, the frame 46 is lowered onto the bar 30 so that the membrane covers the thread in the groove. Post- 51 packs in chamber 32 through tube 33, the air crossing the chute, vibrates the tabs 53, and they, in turn, vibrate the thread in the direction perpendicular to the direction of the movement of the air flow, moving along the thread along the channel along the thread 55. Vibrating the end of the thread causes the separation of the fibers and the separation from it of the loose fibers on the spindle due to the tension of their air flow. The end of the thread can be cut with knives 58 and 59 before vibration, one 58 of which is fixed on stand 43, and the other 5§ moves with the bar 30 due to its easy mounting, carried out by the adjusting screw 24. The best quality indicators for preparing the end of the thread to the connection is achieved by vibrating the membranes made of rubber with a thickness of 0.2-0.3 mm, frequency 500-2000 Hz and amplitude of about 1 mm. This method allows high-quality preparation of the ends of the threads of different warns both from ring spinning machines and from ringless spinning machines, in particular, pneumomechanical, without breaking the fibers, providing high-quality subsequent connection of the ends of the threads with the necessary strength and without noticeably losing the thread.
