DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a fiberizing device for transporting fibers, particularly glass fibers, and more particularly to mechanical reinforcement of bushings of the fiberizing device. [Prior Art] Traditionally, a so-called direct melt fiberizing apparatus includes a flow block member that receives molten glass from a feeder, and the feeder is connected to the furnace in which the glass is attached. Melting; a bushing block; and a bushing. The bushing is provided at the bottom of a plate member, the plate member being provided with a plurality of orifices. The molten glass flows from the orifices into the fine fibers into the plurality of fibers. The fibers are gathered into at least one bundle. The diameter can vary substantially from 5 microns to 33 microns and the bundle moves toward a combined device to form at least one roving and, for example, rolled up. Depending on the application, the rovings can also be chopped (chopped strands) or sprayed onto a belt (continuous strand mat). The products obtained are mainly used in various reinforcement applications. The bushing is substantially made of a platinum-rhodium alloy that is electrically conductive and mechanically and chemically resistant at very high temperatures over time. The bushing is heated by the Joule effect to adjust the glass contained in the bushing to a temperature of about 1100 to 1400 degrees Celsius, and is retained in the molten state so as to be from the orifice of the dumping plate Take out. The heating of the bushing is substantially generated by an electrical transformer through a connection such as a two terminal, each end -5 - 200930673 sub-position at each terminal of the opposite terminal of the bushing to electrically connect the components outside the bushing . a screen positioned inside the liner, in a plane approximately parallel to the tipping plate and on the side of the liner block, the screen being intended to thermally condition the glass and absorb by the molten glass Part of the hydrostatic pressure applied. The molten glass exerts a high pressure of about 6000 bar (Pa) on the components of the liner, particularly the sides, the screen and the dumping jaw. Throughout this time period, this pressure is combined with the thermal creep of the constituent material of the bushing and the expansion of the constituent elements of the bushing, applying high stresses to the components of the bushing, and primarily causing the dumping plate The deformation causes a regularity problem in the linear density of the fiber obtained by the fiberization, accompanied by efficiency and quality problems. Furthermore, the external electrical connection elements attached to the terminals of the bushing are sometimes suspended by the bushing, which exerts an additional tension on the bushing which also causes the bushing to deform throughout the time period. Ο In order to locally exclude the deformation of the bushing, it is known to add a plurality of reinforcing elements between the screen and the substrate and between the sides thereof to the inner portion of the bushing, the reinforcing elements Parallel to each other and positioned in a plane that intersects the plane of the dumping plate and traverses the long side of the bushing. In the remainder of the description, the terms above and below are defined as the direction in which the glass flows through the liner, and the glass is extruded from the upper portion toward the lower portion. U.S. Patent No. 3,920,430 discloses such reinforcing elements. Each of the reinforcing elements comprises a high temperature resistant metal hollow longitudinal rod and a ceramic rod disposed in the hollow rod of -6 - 200930673. These reinforcing elements inevitably allow the bending resistance of the bushing to be improved. However, they form an increased element that generally comprises the same durable material as the liner, made of platinum or even a uranium-niobium alloy, further increasing the weight of the liner. The weight of the liner is still a major concern due to the high cost of the material constituting the component of the bushing, uranium or platinum alloy. Another reinforcement solution includes a device external to the bushing. In any of the bushings, cooling fins are provided and disposed between the rows of orifices for transporting the fibers, and the cooling fins assist in cooling the glass cannons. The fins may also have the function of supporting the dumping plate. The dumping plate rests on the fins in this manner, however there is a thermally and electrically insulating ceramic material interposed in the middle which is resistant to the high temperatures experienced by the dumping plate. U.S. Patent No. 5,312,470 shows this solution. However, despite the presence of the insulation material, the cold spot is left behind by the dumping plate in contact with the cooling fins, which can change the thermal balance of the pour spout, resulting in changes in the final product. And the deterioration of the nature of the product. Moreover, this configuration does not allow for the use of a system that allows for variations in the height of the cooling fins relative to the dumping plate to accurately adjust the thermal balance of the dumping plate. SUMMARY OF THE INVENTION An object of the present invention is to provide a solution different from the prior art which ensures the bending resistance and deformation resistance of the bushing throughout the time course, while 200930673 significantly reduces the weight of the bushing to promote the raw material. This saves, and does not interfere with, the behavior of the bushing, such as the adjustment of the cooling fins, while additionally providing the ease of acceptance of the reinforcing members to assist in recirculating the constituent material of the bushing. According to the invention, a dumping plate for a bushing conveying fiber intended for a molten material, in particular glass, comprises a plate member having an inner face and an outer face opposite the inner face, a plurality of orifices extending therethrough a plate member, and the molten® material is intended to flow through the orifices, the dumping plate being characterized in that a majority of the plate member is shaped 'and the plate member includes ribs projecting from the inner face, each rib having A trench having an opening in the plane of the outer surface. Although a material is added to create the rib, a shaped dumping plate made of a highly heat-resistant, generally expensive material, such as a platinum or platinum-rhodium alloy, can be in the amount of material being made relative to a conventional liner. There is a significant gain', especially as it integrates the stiffeners to where the platinum lining has been added to the interior space of the liner. This increase in material can result in significant savings in the cost of the raw material of the liner made. Furthermore, this novel configuration of the dump panel ensures easy recycling of the bushing and also results in cost savings. This is because the ceramic material that will be designed to accommodate the stiffeners of the ribs will be more easily removed from the dumping plate than in the prior art', in particular the ceramic material is completely surrounded by the uranium lining. Furthermore, if desired, the dumping plates that are separate from the stiffeners will be subjected to a mechanical treatment during recirculation for reusability. In addition, if the stiffeners have deteriorated, it is easy to remove the stiffeners from the bushings to make it possible to change these stiffeners during the life of the bushing -8 - 200930673. According to a feature, the ribs extend along the entire width of the panel comprising the dumping plate. According to another feature, the panel includes a plurality of apertures, and the ribs are disposed between the columns parallel to the array of apertures. Preferably, the panel including the dumping plate includes short studs disposed in and extending from the outer surface of the aperture. 〇 These short studs are either fixed to the panel by welding or, for example, by stamping into the panel. The ribs of the panel can have a variety of shapes and have a polygonal or curved cross section. According to the present invention, the tipping plate is advantageously a part of the bushing. The bushing also includes a stiffening strip based on a material having a thermal latent resistance greater than the thermal potential of the material constituting the panel. The resistance is changed and each stiffener © is placed in the groove of the ribs of the dumping plate. Preferably, the stiffeners disposed in the ribs do not protrude from the outer surface of the panel including the dumping plate, which may make it possible to not interfere with the height of the cooling fins relative to the panel including the dumping plate Adjustment outside the piece. According to a feature, the panel comprising the dumping plate rests on the stiffeners without being secured thereto. Due to the fact that there is no engagement between the panel comprising the dumping plate and the stiffening strip, it is straightforward to remove the stiffeners from the dumping plate throughout the time course of the service life of the bushing , if necessary, change the stiffener that may be damaged. -9- 200930673 According to another feature, the stiffening strips have free ends that protrude from lateral sides of the dumping plate and are supported by a bracket system to finally tie the bushing to the In the fiberizing device. According to a variant embodiment, the support system comprises a concrete packaging material surrounding the ends of the stiffeners. According to another variant, the bracket system is associated with the ends of the stiffeners to support them, and is located particularly below the ends, and is formed by a single piece of truss-like pattern so that One of these stiffeners is supported in a holistic manner, otherwise it is formed by several parts to individually support each stiffener or a group of stiffeners. Subsequent support systems that only support the stiffeners may be preferred because they allow the components of the bushing to expand without retracting stress. Preferably, the stiffeners are at least partially coated with a corrosion resistant material. Finally, the invention relates to a method of producing a fiber of a dilutable material, in particular glass, using such a bushing as described in accordance with the invention. [Embodiment] Figure 1 illustrates a bushing 1 intended to be part of a fiberizing device, the fiberizing device comprising, in particular, a bushing block member 100 just above the bushing, and above but not shown Out of the flow block. The bushing 1 is capable of conveying glass fibers from, for example, molten glass flowing from the bushing block member 100. The invention can of course be applied to any type of molten material comprising heat -10-200930673 plastic material, which can be fiberized. The bushing defines its range by a dumping plate la, a wall lb' and a screen lc. As can also be seen in Figure 2, the dumping plate 1a comprises a plate member 1 of a rectangular shape, preferably an aperture 2 through which the short staples 20 extend, and enabling the dumping plate A reinforcing sheet 3 or a stiffening strip that withstands various stresses experienced throughout the time course. 〇 The panel 1 has two opposite faces 11 and 12, which are referred to as the inner face and the outer face, respectively. The inner surface 11 is flipped toward the inner space of the liner; it is intended to receive the molten material. The panel 1 is provided with a penetrating orifice 2 through which the molten material is intended to flow. The outer portion is external to the bushing and has pierced short studs 20 extending through the apertures 2, and the molten material is intended to be tapered in the form of fibers by the apertures. The staples 20 are secured to the panel, preferably by welding, 〇 or being formed into most of the panel, particularly by stamping. The panels and the short staples are based on a high temperature resistant material and are substantially made of platinum or ruthenium based platinum alloy. The apertures 2 and the short staples 20 are arranged in the form of a plurality of columns 2 1 extending across the width of the panel. Most of the shape of the panel 10 is designed in accordance with the present invention. As more visible in Figure 3, the inner face 11 includes ribs 13 that project toward the interior of the liner. The ribs 13 provide grooves 14 which have their openings in the plane of the outer face 12. -11 - 200930673 Each groove 14 of the rib accommodates a stiffening strip 3. The ribs 13 are configured to be inserted between the rows of orifices so as not to reverse the flow of glass through the orifices. The ribs 13 on which the stiffeners 3 are placed extend over the entire minimum extension of the panel 10 (Fig. 2). Depending on the size of the dumping plate and the thermal consistency provided to the dumping plate, the frequency of the ribs is selected and between the rows of orifices, such as between each column or every second or third column The fixed position between. The shape of the ribs 13 can be varied, and the cross section can be a polygon such as a rectangle, a square, a triangle (Fig. 4), a trapezoid shown in Fig. 2, or a circular shape, such as a semicircle. (Figure 5). The shape is preferably adjusted depending on the desired mechanical impedance, some shape that would make them more suitable for this, and/or the amount of material that is readily available for production, and/or further desired. The stiffeners 3 comprise a material having a thermal latent resistance that is greater than the thermal latent resistance of the material comprising the panel. The stiffeners, such as ceramic rods, are preferably coated with a corrosion resistant coating, such as a platinum coating. The ceramic material may be, for example, aluminum, tantalum nitride, zirconia, or a nickel-based, iron-based, or titanium-based ODS (Oxide Dispersion Strengthened) alloy, or a tungsten, molybdenum or niobium-based alloy. Refractory alloy. The stiffening strips 3 are disposed in the grooves 14 of the ribs, preferably not protruding beyond the outer surface 12, and the free ends 30 and 31 pass through the lateral side edges 15 and 1 of the panel 1 6. Preferably, the stiffening strips have a cross-section that is approximately the same as the inner cross-section of the groove for -12-200930673 for inserting the stiffeners into the outer casing in a tight fit. The stiffeners are capable of supporting the dumping plate la, and the dumping panels are only placed on the stiffeners without additional securing mechanisms. To ensure that the tipping plate is properly supported, the free ends 30 and 31 passing over the stiffening strip of the tipping plate are intended to be securely held in place in the fiberizing apparatus by a suitable bracket system 4. The bracket system 4 can be such that the ends 30 and 31 of the stiffeners are packaged into a frame 40 of hard material such as concrete. Figure 6 shows that the frame 40 is a fully open portion that causes the ends 30 of the stiffeners to be seen for better understanding. As a variant, the support system 4 can include an associated support device' that is, for example, located below the stiffeners to support them. The support means can be formed by a single element in the form of a frame for supporting all of the stiffeners in a unitary manner. According to a preferred variant, it may be formed by a number of parts, such as angle brackets 41 (Fig. 7), which support the stiffeners of the group or may individually support each of the stiffeners.
