(54) DEVICE FOR SUBMITTING THREADS TO TEXTILE

MACHINE

At one end of the drum, a ring 10 is fitted, which is adapted (5 to move the thread yarns along the working direction towards the pickup zone I; the drum. The ring Yu is connected to the hollow shaft via a ball bearing (not shown). In the receiving area The filaments on the drum are mounted with a conical element 11 consisting of a ring ring covering the drum 12 and 12 and a certain number of teeth 13, the number of which corresponds to the number of grooves. The teeth fit exactly into the longitudinal grooves so that the element 11 exactly moves in the longitudinal Using these teeth and a ring 12 closely encircling the drum circumference, the surfaces of the 14 teeth facing the ring 10 are chamfered about the imaginary axis A of the drum towards the ring 10, thereby forming part of the conical surface, which together constitute the cone tapering in the direction of the ring, the surfaces 14 may be rounded or flat, respectively, to the parts of the surface of rotation: a cone. The pushers 15 distributed along the perimeter act on the conical element 11, one of which is shown in FIG. 1. These pushers are inserted through the wall of the housing with the possibility of movement and are under such a load created by the tension springs 16, which tend to move the movable conical element in the direction of the movable ring. On one of the pushers fixed switching element 17, which interacts with the switch 18 in the circuit 19, regulating the operation of electr the magnetic coupling. Thread F is charged through brake 2, and out through outlet ear 21 "The device operates as follows. The thread comes from the reel (shown in the drawings ke) through -Termoz 2O and then S hollow. shaft 4, from where the bar of Aban 1 and g: ovo comes out from the opposite end, is knocked along the radius to the eyelet Y. When the ring 5 is rotated, the eyelet winds the thread on the still-standing drum. The ring, as a result of its inclined position on the Baku floor, when the shaft rotates, starts akbriroa-b at the same time shifting it again - .. 92nnye turns in the SiF R. Sif R.P. in this way, an interim reserve of the yarn is formed on the Barbara in the form of its own (uneven) and unevenly wound places & dgg layer and not ;; of layers, hank | 1ti K. As a result, the spring load. Element 11 advances in the direction of the arrow P j so that its teeth are placed under and behind the hank of the thread K. As can be seen from FIG. 2 | the threads of the thread are stretched in the radial direction, that on the surfaces 14 of the teeth 13, winding of the threads 8 / in a single layer is obtained (From this winding zone in a single layer, the thread is pulled and passes, as is seen from Fig. U, through the thread take-off ring 5, through the outlet eye 21, Ogtu and thread f enters the textile machine. Element 11 serves at the same time pe y the size torch of the intermediate thread reserve formed by E. coil K. If this reserve is too small, the pusher 15, under the force of the spring 16, is bent down (Fig. 1) i It is NOTOPABLE that the circuit breaker operates. As a result, clutch 9 closes and the Idling winding If the intermediate thread reserve exceeds the upper limit, the switching element moves away from the switch and turns off the thread winding drive. they rotate together with the drum, and the ring does not receive any fi / iral motion, but is fixed on an inclined plane opposite the stationary shaft of the drum. Instead of ring 10, cone-type tools may be used. The switch 18 may be located directly in the engine control unit 7, formula of the invention. A device for feeding a yarn to a textile Chshin containing a thread-storage drum with longitudinal grooves, a device for moving the threads of the thread along the drum in the direction of its removal, and a conical element in contact with the thread, which encloses the drum in the zone of removal of the thread from it, which is distinguished by the fact that, with the increase in the uniform tension of the thread when it leaves the drum, the conical The cue element is mounted on the drum freely, it has teeth that go along the grooves 6apa6a} ia and is spring-loaded in the directions to the drum thread receiving loop.
