    A spinnerette has an extrusion crucible provided with extrusion nozzles in its bottom wall, and a melting crucible atop the extrusion crucible. The melting crucible is bounded in longitudinal direction by walls having arcuately curved wall segments so that the interior of the melting crucible is composed of a plurality of generally cylindrical compartments which are arranged side by side in the longitudinal direction and which open into one another where they adjoin each other.

    lists, but such a measure increases the consumption of metal and creates an obstacle to moving glass. The purpose of the event is to improve the quality of glass fiber by uniformly distributing the temperature and the stability of the shape of the sewing chamber. The goal is achieved by the fact that in a metal spunbond feeder for obtaining glass yarns, including a melting and processing chambers separated by a screen, the spinneret plate and conductors, the firing chamber is made of interconnected in forming vertically mounted idindyndic segments that are open on facing one side to the other. and is provided with crossbars located at the joints of the shield-segments, the height of which is less than the height of the melting chamber. In section, cylindrical segments are elongated in the shape of an oval or ellipse. The side walls of the cylindrical segments are made in the upper part with a curved surface, the transition into a flat. FIG. 1 is a schematic representation of a metal spunbond feeder, side view, in FIG. 2 - the same, top view with partial extension of the melting chamber; in fig. 3 - the same, option; in fig. 4 shows section A-A in FIG. 3; in fig. 5 - spherical feeder in axonometry. The spinneret feeder consists of an operating chamber 1 with a die plate with spinnerets 2, the melting chamber 3 is implanted into the working chamber. The initial glass, for example, in the form of granules, is fed into the melting chamber. The conductors 4, forming the zones of electrical heating, are attached to the spinnered feeder. The spinnerets 2 are welded into the die plate 5 of chamber I, connected to the melting chamber by 3 holes 6 for the passage of glass. The holes 6 are drilled in the screen 7, serving as the bottom for the melting chamber 3 and the ceiling for the working chamber 1. The melting chamber 3 is formed from a series of open, completely cylindrical segments 8 and 9 joined at the meeting point. At the junction, the structure is hardened by crossbars 10, perpendicular to the length} of the 1st axis and extending between the walls of the cylindrical segments 8 and 9 and with a height of lower height of the melting chamber. The side walls of the smelting chamber are defined; parallel lines, which in segments 8 and 9 are consistent with the lines of the gull of cylindrical arches (axes .. pass in the longitudinal median plane of the chamber) and in segments go in the shell lines of smaller cylinders whose axes lie in a plane, the passage is perpendicular the longitudinal median plane through the points of contact or intersection of two adjacent segments. Thanks to this design, conditions are created that on the one hand contribute to uniform loading of the melting chamber 3 and, above all, uniform temperature distribution in the glass melt supplied to the dies, and on the other hand, a high stability of the body having a tubular cross section in which the crossmembers 10 are installed. Vaulted the walls prevent the glass melt from compressing with large temperature fluctuations. In addition, changing the length of the walls of the smelting chamber with respect to the length of the die-feeding feeder, i.e. more or less curvature, you can change the temperature, which is a function of the length of the walls. This means that choosing the length of the walls determines the amount of electrical resistance and at the same time the heating power. The application of such a principle is shown schematically by the example of the embodiment in FIG. 3, which is different from the example shown in FIG. 2 by the fact that the individual segments 8 and 9, which form the melting chamber, have a cross section of oval or elliptical shape, i.e. the walls have other radii of curvature, the centers of which should not lie in the median longitudinal plane. Another embodiment is shown in FIG. 5, where the amount of heat transferred by the walls to obtain the initial glass melt melt can be regulated by the height of the melting bath in such a way that with CTOpoiibi the load is smaller, and in the separation plane between the melting chamber and the filter plate, where the material is already largely refined, more . The temperature difference may be, for example, 200 ° C, while the temperature of the walls at the top is about 950 ° C and at the bottom is about 1150 ° C. The melting chamber consists of a series of segments 8 and 9 that cut into each other, and their joining, as in Examples 1-4, the melting chamber has a relatively small height. And here are cross-beams 10 that serve to harden the structure. The side walls of the smelting chamber in the upper loading part in the longitudinal direction form a curvilinear surface representing a set of cylindrical segments, while in the lower part, with a dividing wall to the dividing wall, they have a flat surface.
    With the same length of the die feeder, the length of the side walls in the upper part is longer than in the lower part, approximately from 15 to 30%, therefore, the electrical resistance is correspondingly greater and gradually becomes less. The consequence of this is that less heating of the upper part is compared with that of the lower part; therefore, heat transfer from the walls of the glass mass occurs. Despite the temperature difference in the proposed form of use, it is possible to maintain the stability of the structure, as in Examples 1-4, however, the heat load is lower in this case.
    Thanks to the application of the proposed feeder, it is possible to regulate the heat load or heat transfer to the glass melt by changing the configuration of the side walls of the melting chamber of the spinneret feeder. In addition, the curvature may vary with a change in the length of the spinnerette feeder, for example, the design of the side walls may be such that the radius of the convexities in the middle portion of the spinnerette feeder is smaller than in both boundary sections.
