    A device for feeding yarn with a constant adjustable tension, for use in weaving looms and in other weaving machines, comprises braking means acting onto an end cap of the winding drum (3) - held stationary - of said device. Such means consist of a plurality of elastically yielding metal elements, positioned radially into a support (13) designed to envelop said cap and mounted with possibility of self-centering in respect of said cap, said elements engaging the outcoming yarn (4) along a circumferential area of the cap having a slightly smaller diameter than that of the winding drum of the feeding device.

    The invention relates to weaving equipment and relates to threading under the fixed yarn drum devices used to feed the weft yarn. A device for braking a thread to a thread-feeding device with a fixed thread-storage drum for weaving machines is known, which comprises a support installed with the possibility of axial adjustment relative to the threading edge of the drum, which carries radial elastic metal plate elements that rest on the thread-discharge edge of the drum along its rim. the shape of a truncated cornus, the most of whose base is carried by an elastic ring, and the lamellar elements are connected with the last Cll "However, the known osoblenie has low reliability, since it does not preclude the formation of the cylinder when the yarn unwinding from the drum. The aim of the invention is to increase the reliability of the operation. The purpose of the invention is to ensure that in the device containing the axially adjustable relative to the filament edge of the drum, the support carries radial elastic metal plate elements resting on the filament edge of the drum along its perimeter, while the support has the shape of a truncated a cone whose larger base bears an elastic ring, and the lamellar elements are connected with the latter, the lamellar elements are console reinforced in an elastic ring and their free ends are supported on the inner conical surface of the support, which is connected to the means for adjusting its axial position by means of self-centering subtypes, while the larger base of the cone covers the thread-accumulating surface of the drum, and the smaller base is coaxial with a drum. peephole. The means for axially adjusting the position of the support comprises a fixed rod and a slider mounted thereon, connected by means of a forked suspension to the support, while the self-centering bearings are located at the suspension attachment points. FIG. 1 shows a thread-feeding device with a brake assembly device, a partial section; figure 2 is a brake pads device, front view; on fig.Z - ring with plate elements, two types; figure 4 - bearing assembly, side view; Fig. 3 shows an embodiment of the support. The thread-feeding device (Fig. 1) has a casing 1 inside which an electric motor and an electronic control circuit (not shown) are mounted, as well as a thread-wrench lever 2 for winding the thread on the stationary cylindrical drum 3, which serves to accumulate the threads of the thread 4. A detector is mounted opposite the drum 3 5 the number of threads on the drum and the magnetic system 6 to prevent rotation of the drum 3. The device also has a device 7 for braking the thread on the surface of the drum 3. The thread-winding lever 2 is made cranked and hollow and has a shaft 9 Which is also an electric motor shaft. A drum 13 is mounted on bearings on the extension of shaft 9, which keeps two magnets of system 6 from rotating, one of which is rigidly fixed to case 1 and the other in drum 3. Device 7 for braking the outgoing thread 4 has radial elastic metal lamellar elements 10 fixed in a support having the shape of a truncated cone 11, the larger base 12 of which covers the thread storage drum 3, and the smaller 13 forms the inner conical surface on which the lamellar elements 10 are fastened e cantilever. In this case, the elements 10 rest on the flow-out edge of the drum 3 along its perimeter. The support includes a peripheral socket 14 provided inside the rim 15. A console elements 10 are fastened to the nest with an elastic ring 16 made of plastic material. The free ends 10 are supported in a ring 17 of a smaller diameter support so that each element 10 works like a leaf spring. The support with lamellar elements 10 is fixed relative to the drum 3 on self-centered dix bearings, which ensures uniform braking force on the thread 4 along the entire perimeter of the thread outflow drum 3. The support part 13 is attached with the lever 18 and the fork 19 to the fixed rod 20 and can be adjusted in position regarding him. For this purpose, the lever 18 is connected to the rod 20 via a slider 21, bearings, a locking screw 21, and a fork 19 is attached to it using bearings 22, oscillating with on an axis perpendicular to the longitudinal axis of the drum, 3, the fork 19 is in turn supported. ) live part 13 of the support, installed with the possibility: swing on an axis perpendicular to both the longitudinal axis of the drum 3 and the axis of the fork of the plug 19. This axis of the swing is mounted in two bearings 23 mounted in diametrically opposite places on the rim 15, the possibility of oscillation around two axes gives you the opportunity ntam 10 exert uniform pressure on. filament edge of the drum 3, which ensures a uniform tension on the thread at the outlet and a decrease in the likelihood of balloon formation. In the smaller base of the cone, a filament ceramic ceramic eye 24 coaxial with the drum is made. Another variant of the hinge installation of the device 7 is possible (Fig. 5). In this case, a self-aligning radial ball bearing 25 is used, which is connected by means of inserts to a shaft 26, which is secured to the lever 18, while the shaft 26 appears to pop and also serves as a thread-guiding eye. The work of the fixture is carried out in the following manner. The thread 4 enters the device through the hollow shaft 9 of the engine, winds in several turns (the number of turns is controlled by the detector 5, which controls the activation of the engine) with the help of the lever 2, passes between the curved periphery of the thread outflow edge of the drum 3 and the brake brake 10 and enters the eye 24 The braking force of the elements 10 on the thread 4 is adjusted by moving the slide 21 along the rod 20 to one side or the other. Due to the fact that the thread braking is carried out along the peripheral surface of the casting edge of the drum 3, which has a diameter close to the diameter of the drum 3, the thread is subject to minor deviations along its path from the drum to the eye 24, which eliminates the formation of the thread balloon. The device as a whole works as a weaver thread store when it is fed into the zone of fabric form.
