    A yarn feeding or supply apparatus for textile machines, particularly knitting machines, has a rotatable storage drum supported on a holder, which can be coupled to a drive source setting it into rotation and having yarn guide elements for directing yarn to and from the drum associated with it. In order to assure satisfactory formation of windings of storage yarn on the storage drum even with yarns which may be difficult to handle, the arrangement is such that the yarn supply guide element directing the yarn onto a first conical circumferential surface, acting as the yarn run-on surface, is disposed at least at the height of this surface; that the storage drum has an inwardly receding conical yarn support surface adjoining a second conical circumferential surface in the axial direction, the cone angle of the yarn support surface being substantially smaller than that of the second conical surface, an annular surface extending essentially at right angles to the two conical surfaces being disposed between these two conical surfaces, and the axial length of the yarn support surface being appropriate for receiving an intermediate group of yarn loops comprising a plurality of adjacent yarn windings; and that the conical yarn support surface merges with an essentially cylindrical circumferential surface of the storage drum accepting the storage loops of yarn.

    The invention relates to the textile industry and relates to a device for feeding the yarn on a textile machine with a thread storage drum.
    The purpose of the invention is to increase the reliability of work.
    Figure 1 shows the proposed device, side view; figure 2 - cumulative drum device, a partial axial section, side view; fig. 3 - the same, with the bottom image of the movement of the thread; figure 4 - section aa in figure 3.
    The device for feeding the thread (Fig. 1 has a holder made in the shape of a box, which with the help of clamping device 2 can be mounted on the textile machine body, for example, on the end of the body is round in the die machine. In the holder 1, the shaft 3 is rotatably mounted on the upper the holder side carries a drive belt 4 disk with high torsional strength, and on the bottom side of the holder a storage drum 5 is connected to it. Thus, through the drive belt 4 disk the storage drum 5 can connect driven (not shown) and driven into rotation.
    On the holder 1, on the side of the storage drum 5, there are two thread-guiding eyes 6 and 7, which lead the thread 8 from the feed reel through the nitate resident 9 to the guide eye 0, from which the thread goes to the storage drum 5. The thread 5 coming off the drum 5 passes, fixed on the holder 1, the guide eye 11, behind which there is another thread-guiding eye 12 at some distance, which is also fixed on the holder I. The thread passing through is controlled by the feeder probe 13, while the control of the outgoing thread n The gauge is driven by probe 14 of the thread. The probes 13 and 14, which control the presence of the thread, touch the thread in a known manner and actuate the shut-off elements located inside the box-shaped holder 1 as soon as the tension of the thread weakens or the thread tears.
    The construction of the storage drum is shown in FIG. 2., where the drum 5 is full, but it can be composite.

    A storage drum 5 made in the form of a rotating body has a receiving conical section 15 with a straight generatrix, the largest diameter of which (pos. 16) is near the input end 17 of the drum 5 and is separated from it by an axial cylindrical surface 18. The receiving section 15 forming the surface the running of the thread forms an angle of about 30 with the axis 19 of the drum 5. In the zone of the smallest diameter, it intersects the annular surface 21, which extends generally perpendicular to the axis 19 of the accumulation drum 5. In this case, the receiving section 15 adjoins the annular surface 21 through a rounded zone 22 whose radius is about 0.5 mm.
    Inside the annular surface 21 there is an adjacent axially narrowing water-flow zone, the beginning of which is formed by a conical surface 23, 1 1 which forms a direct forming part, which is inclined to the axis 19 of the drum at an angle of about 60-70, preferably 68 and whose projection 24 is axially 19 drum 5 is relatively small (for example, about 0.6 mm).

    Axis 23 of axial direction of drum 5 adjoins the surface of a truncated cone 25, which has a straight line, the axial length of which is chosen so that it is sufficient to receive part of the turns of the storage drum 5. The surface of the cone 25 forms an angle of 2 to 10 ° with the axis 19 of the drum 5. The cylindrical side surface 27, which has a relatively large axial length and is used to receive the whole skein of threads, abuts on it through the shoulder 26. The cylindrical portion of the yarn-water zone ends on a radially protruding rotary annular shoulder 28 located on the outlet side of the drum 5, the cross-sectional shape of which can also be rounded.

    The shoulder 26 has only a small extent of about 0.05 mm. Options are also possible in which the shoulder 26 can be refused, then the surface of the cone 25 passes into the cylindrical side surface 27, and the transition of both surfaces can be rounded or have a rotating edge.
    The guide eye 10 is located on the input end side of the drum 5 perpendicular to its axis 9. The eye 10 is located on the holder for movement along the height, and its axis height is set so that it is at least at the height of the larger base of the receiving conical section 15 i.e. its axis 29 extends at a distance of 30 to the top of the annular surface 21. The distance 30 can be chosen so that the axis 29 passes over the end 17 of the accumulation drum.
    The peephole 10 leads the thread 8 approximately tangentially along the surface of the receiving section 15, which acts as a threading surface, and the thread goes through its rounded zone 22 at the transition point to the annular surface 21, so that in this transitional zone to the annular surface 21 in motion of the yarn kink B.
    The thread 8 passes from the rounded zone 22 in the form of a chord into the transition zone between the second conical surface -23 and the cone 25, and a second bend B is produced in the movement of the thread. This is a chord-like passage of the thread shown in FIG. that the thread 8 does not touch the annular surface 21 and that the second conical surface 23 only in the corner at the surface of the chord 31 contacts the thread to impose a nit

    In the form of coils lying one behind the other onto the surface 25. In this case, the axial feed of the last thread turn is carried out due to the fact that the chord 31 of the thread at bend B always appears in the aforementioned angle, and between the last turn of the thread and the second With the focal surface 23, a wedge-shaped gap appears, into which the thread 8 can enter.
    Thus, an intermediate coil 32 is formed on the surface 25, consisting of a certain number of turns of threads lying next to each other, which are frictionally connected to the adjacent surface 25 of the accumulating drum 5, so that there is an uninterrupted, i.e. without skipping

    ,
    zyvani, threading. The axial length 33 of the conical surface 25 is projected along the axis 19 of the drum 5 at least 1.5 mm (it is 1.5 to 5 sec.).
    The intermediate coil 32 on the conical surface 25 is continuously moving downward along the threads of the threads constantly forming on its upper side,
    and on the second conical surface 23 - to the turns of the threads, pressed respectively to the previous turn. At the same time, the coils lying at the very bottom, one after the other, reach
    5 through the shoulder 26 of the cylindrical side surface 27 on which they form their own, consists of a plurality of turns of a skein of threads, or a accumulator of coils 34, on the lower side of which the thread 8 through the peephole 11 tangentially goes down. The height position of the guiding eye 11 can be selected so that the outgoing thread r goes through the collar 28.
    When moving from the intermediate core 32 lying on a conic surface 25 to the coil 34 on a cylindrical side surface 27, the individual threads of the threads are slightly weakened; moreover, the degree of attenuation is set by the radial extent of the shoulder 26 or the angle at the apex of the surface cone 25. So
    5, the necessary axial threading can occur in a simple way in the area of the skein of 34 threads, without leading to the danger of falling off separate turns of threads on each other.
    The functions of the thread-feeding device and the operation of its cumulative sleep drum from the described sequence of forming turns and advancing the thread in the device.
    Since there are only relatively simply made geometrical surfaces on the accumulating drum, the manufacture of the drum is much simpler than the manufacture of structures that require large zones of drum surfaces with precisely predetermined constant bending. Therefore, the storage drum can be made whole or assembled, and in the latter case, the cylindrical side surface can also be made on a ring, the surface of which is
    need hardened. Thereby, very simple conditions are obtained when the ring is made of a corrugated sheet, the waves of which are located in the axial direction. The surface of the abutting thread can be made of a corrugated sheet, which equally applies to the cylindrical side surface. Such a corrugated sheet or corrugated ring is particularly cheap to manufacture; at the same time, it guarantees only the ordered position of the threads of the thread, which is applied to the corresponding surfaces,
