The present invention is directed to an apparatus for making fibers from elongate material that is changed by gas airflow in forming a pair of at least oppositely rotating whirlwinds.

The present invention relates to the elongation of thermoplastics, in particular inorganic materials such as glass fibers or similar composites which are converted into a molten state by heating.

The present invention is also suitable for forming fibers from organic materials such as polystyrene, polypropylene, polycarbonates or polyamides.

However, the described apparatus is particularly beneficial for thinning glass fibers or similar thermoplastics, and therefore the present disclosure describes the use of the example method.

Techniques for using swirling airflows to produce fibers by thinning molten glass fibers are already known. In particular, French Patent Publication No. 2233318 is directed to a larger area main gas stream by directing a second injection port or a gas injection port associated with a carrier injection port and causing the aforementioned injection port to penetrate the air stream described above. The formation of pairs of reciprocating whirlwinds in the region of the resulting interaction was described, as well as conducting the outflow of molten glass fibers into this region of thinning.

In the machinery used to carry out the process, the glass fiber feed orifice, which has flowed straight out of the glass fiber to obtain an area of interaction, is located at the boundary with or close to the main stream. Done.

However, the position of the glass fiber feed orifice is located at a slight distance from the boundary of the main stream, as described in French Patent Application No. 7504970, filed on February 18, 1975 in the name of the applicant. It is possible and also by gravity to conduct the outflow of the fiberglass into the region of the aforementioned interaction.

At a slight distance from the boundary of the main stream, one can imagine the location of both the glass fiber feed orifice and the spinning orifice at the second outlet, so that the runoff is thinner (one is the second outlet). The flow of glass fibers into the corresponding interaction zone by the action of the injection port.

In particular, this arrangement is described in French Patent Application Nos. 7603416 and 7637884, filed February 9, 1976 and December 16, 1976.

As mentioned in this application, in the second injection port (or carrier injection port) which conducts the glass fibers into the area of interaction as a periodic flow, it flows in a stable thin layer located between the two rotating whirlwinds. Leads to the formation of a region. In this thin layered area, the free-flowing liquefied oil acts, so before the rat reaches the main stream, the outflow of the glass fiber enters the region of the whirlwind where the carrier injection fusion downstream. Therefore, the first stage occurs during the transport of glass fiber outflow pairs of blasts at the transport outlet, while the second stage (often beneficial in some cases) dependent on the action of the first stage is infiltration of the transport outlet and outflow of the glass fiber. Occurs in areas that interact with the main stream after a partial thinner inflow.

The blast and thin layered areas of the carrier injection port, combined with the respective fiber forming centers, are generally created by disturbing the injection port causing the transport injection port to deflect, and the glass fibers are conducted toward the transport injection port and the main stream. Despite the gaps between the regions, the deflection of these outlets contributes to making the operation stable and constant.

The present invention is an improvement on the machinery used to perform this process. The invention is also equipped to arrange a feeding orifice for supplying the outflow of glass fibers and a spinning orifice for supplying a delivery outlet at a slight distance from the main stream.

In addition, the present invention can be envisaged to be used at least locally to deflect the flow of the carrier injection outlet, thus forming a thin layered region as a pair of whirlwinds.

However, an improvement by the present invention is a disturbance and preferably deflects the delivery outlet by means of a device of a different shape, which device is described in the above-mentioned application to obtain more stability in supplying the elongate material. Get the device from that.

It is also an important object of the present invention to obtain good stability and narrow balance in feeding glass fibers, despite the significant gap between the glass fiber feeding orifices and the region of the periodic flow or interaction.

In particular, the present invention envisions the use of a current transformer device or device to induce a delivery injection port, wherein the device inserted into the furnace of the delivery injection port described above is provided with an injection orifice orifice having a convex portion located at which the injection port flows. Both outflows contain elements with a surface in horizontal section.

This element located in the exit of the exit between the spinneret of the exit and the outflow of the thin material causes the flow of the exit of the exit to be locally and generally deflected, as described below.

It should be noted that although the device leads an injection port through at least a portion of the injection port, the device uses the word "current transformer device" in this specification.

Although it is desirable to use this current transformer device and “injection blast” such as conducting the outflow of glass fibers into the region of interaction formed by the main stream to carry out the elongation at this stage, it can be elaborated as one stage. The supply is made to carry out the work, which in turn carries out the elongation as the fan of the delivery outlet.

In the specific context of the following associated drawings, the current transformer device has a circumferential cylinder bar, which is generally the same as the background of the present invention having a state associated with a portion of the surface provided at the ejection opening. It may be replaced by a part or cylinder of solid cylinder. Furthermore, the current transformer device is not required to be a cylinder, but may be configured by having something similar to a cylinder of a diablo, or may also be configured as a continuous element each positioned opposite to the injection port.

The mechanism according to the invention also contains a control device necessary to control the action and interaction of the changing elements used in the relative position fibrillation centers, which are generally referred to as a mainstream generator, an ejector ejector, a current transformer device and a paternity. Say.

Most of the proposed regulators are suitable for all types of machinery for forming the fibers described in the already mentioned patent applications or patent publications.

In some of these forms of machinery, the fiber-forming center contains only three basic components, which are (I), (II) and (III), and (I) is the generator necessary to generate the main stream, II) is the injection port spinneret, and (III) is a source of elongated combustible material that conducts the outflow of the slender material into the zone of interaction by the main stream.

Although changing regulators or machines are used in machinery with only three basic components, as described in the present application or patent application 7637884, at the center of fiber formation having four components to stir the flow of the injection port. Particularly preferred is the use of several changing controls or machines.

Furthermore, the fiber forming machinery allows the changing components in each fiber formation to be positioned relative to the interactions, particularly by angular movement and / or by moving at least one component in association with the source of elongate material. It contains an adjustable device. This is very desirable for the apparatus required to produce fibers from the melting to melt.

It is also one of the main objectives of the present invention to change the operating conditions such as the temperature of the organ of varying components, the composition and viscosity of the effervescent material, the speed of the glass fibers used in the injection port and the main stream and other changing operating conditions Synthesis rule that controlled fluctuation. In addition, deformation or irregularity of the shape and size of the components can be corrected by this control device. Most regulators can perform operations during fiber formation without disrupting the process, although there are several regulators in which a few stops require a temporary stop of the machine when inserted into operation. .

Since the changing components of the fiber forming center are relatively close to each other, another object of the present invention is to automatically assign several components to be recovered (especially the device necessary for spinning the current transformer device and the injection port). This is because engines that supply gas to one of the ejector spinnerets or the main stream may be broken or subdivided in order to operate further away from the source supplying the molten material.

Damage to the changing components of the mechanism is avoided by the above.

FIGS. 1 to 10b, 11 to 12b, 13 to 18, 19 to 21 and 22 illustrate five of the present invention in detail.

In the first implementation of FIGS. 1 to 10b, the first diagram shows a nozzle 13 that radiates a periodic flow, which is connected to the burner or generator 14 required to produce the periodic flow 15. The letter is straightened by a nozzle 13 flowing in a substantially horizontal direction below the glass fiber source indicated at 16. The second injection port or carrier injection port is radiated by radiator 17, which has an orifice connected to the gas supply device provided in bracket 18. Since the second outlet penetrates the main stream 15 and creates an area of interaction, the second outlet is straight into the deflector device 19 which directs the second outlet downstream. The separate outflow of glass fibers made by source 16 is conducted to the second outlet, thereby leading to the region of interaction formed as a periodic flow for conversion into fibers.

The flow from the mixture of the second injection port and the main stream enters the inclined guide channel C 'with all of the elongate fibers to deposit the fibers on the perforated surface of the collecting belt or conveyor 20.

The suction chamber 21 is advantageously located below the top cross section of the conveyor belt 20, and the fibers are concentrated in the form of a mat by the action of a suction pipe connected to ventilators represented by 22 and 23.

Attached to the bolt 25 for adjusting the position of the injection port in connection with the main stream 15 in the vertical direction to give a vertically adjustable bracket in connection with the sieve of the generator 14 required for the main stream (such as in Figure 2). A bracket 18 connected with a support plate 24 with one aperture assists the device to radiate the second outlet.

The sieve of the main flow generator 14, which carries the bracket 18 of the ejector spinneret, is adjusted in the vertical direction by the screw jack 26 connected to the mechanism of the auxiliary device 27.

Therefore, the main stream generator and the ejector spinneret move vertically in combination with each other, especially since the main stream generator and the ejector spinner can be adjusted vertically in connection with the supplied 16 of glass fiber and the guide channel C '. Is moved by

The horizontal position of this entire array is controlled by a suitable machine of screw jacks, shown at 28.

As described with the drawings, the outlet has been prepared for controlling the current flow device and the elements connected to the outlet spinneret.

In FIGS. 2, 3, 4 and 5 showing the mechanism for forming the enlarged fiber, the spinner 17 written in the second injection hole contains the branch pipe 17a for the injection hole, It is equipped with a collector 29 which is assisted by a socket 30 attached to the kit 18.

Thus, the ejector spinneret 17 can be deflected upstream or downstream on the axis of the collector 29, and then fixed at an angled point, for example by stopping the screw shown by 31. In moving the upper part to the lower part as well, this device prepares for the adjustment or transverse movement of the radiator 17 in a direction horizontal to the side of the collector 29. This control is very important because it is accurate and clear to control the delivery outlet with the glass fiber feed orifice described below.

The branch tube 17a of the radiator 17 supplies the spinning orifice 32 of each injection port.

Since the outlet orifice is located in the direction of the current transformer 19 surface, the axis of the outlet orifice is inclined downstream, which is shown on the right side of the drawing. More specifically, it has the shape of the cylinder bar and the cylinder axis of the horizontally located current transformer. It also has a cylindrical cylinder bar and a shaft of a current transformer that is balanced on the row of the exit orifice.

Moreover, the axis of the orifice is almost perpendicular to the volume of the cylinder bar. The bar carries the lux 33 mounted at each end connected to the sieve to the branch tube 17a according to bolt 34. In connection with the branch tube 17a and the outlet port, the current transformer bar 19 is controlled by a tactile 45 (observable tactile) located between the installed Lux 33 and the base of the branch tube 17b. The current transformer bar is adjustable in the horizontal direction to move the current transformer bar away from or directed towards the outlet of the injection or glass fiber.

Source 16 for glass fibers contains bushing 35 with each successive mip 36 with feed orifice 36a and measured orifice 37.

In part 5, the glass fibers are partially cleaned, as indicated by 38 in FIG. 5, which conducts the glass fibers in the form of a valve G or an outflow subsequent to the second outlet.

Therefore, partially elongated glass fibers, however, in 39 the partial elongation or the main flow of the main body enters the region.

FIG. 3 shows nine glass fiber feed tips 36, and also shows the ejection orifice 32 that is located at the corresponding point, corresponding to 11 because the additional outlet is located at the end of each line. Except for one number.

This arrangement can give the same fiber formation to be obtained for the outflow of each of the nine glass fibers used in the examples.

The process of fiber formation obtained with the apparatus described above with reference to FIGS. 1 to 5 is shown graphically from FIGS. 6 to 9. It should be noted that there is a cylinder current transformer bar 19 at the same position as the axis of the cylinder current transformer bar lower than each second injection hole J radiated by the exit hole orifice 32.

This position is shown in each of the four delivery outlets J ₁ , J ² , and J ³ .

This position causes the furnace injection to deflect into the furnace, and the flow of each injection port J separates into upper and lower portions, which affects the Coanda effect while the rat is bent around the lower surface. By attaching it to the upper surface of bar 19 and in front of the curved perimeter.

Since the axis of bar 19 is below the surface of the exit spherical orifice, the upper surface through which the exit port flows has a larger cross section than the lower part. This form may be justified by the evidence obtained herein.

Two parts of the second outlet opening above and below bar 19 fuse downstream of the bar.

6 and 8 show that the flow of injection holes radiated from each orifice 32 spreads laterally or divergently in the axial direction of the current transformer 19, and if the injection holes are spaced directly apart, there is a space in the transverse direction. Spreading causes adjacent injection holes to impinge on each other while the upper and lower portions of the injection holes flow around the 19α, 19β, and 19γ of bars 19 of the corresponding continuous element portion.

For each other, the lateral collision of adjacent exits causes the leap of a pair of counter-rotating whirlwinds with the vertices of the exits adjacent to the surface of bar 19.

As can be seen in Figures 6 to 9, two pairs of whirlwinds are created at each injection port flow. Thus, the lower pairs of whirlwinds 41a and 41b leap at a portion of the flow passing under the lower surface. Whilst the two whirlwinds 40a and 40b form a pair of tops formed by bar 19 at a portion of the flow passing through the top surface.

The two pairs of whirlwinds rotate oppositely. The rotation of the upper pair of each fan is directed downwards along the adjacent surface of the fan, as indicated by 40c and 40d in FIG. 9, and also upwards along the outer surface of the fan.

Conversely, arrows 41c and 41d are upwards along the adjacent surface of the whirlwind and downwards along the outer surface of the whirlwind.

Because bar 19 is located at a horizontal position lower than the axis of the exit port, a portion of the flow located above this bar is more powerful and larger. Moreover, the position of the bar relative to the exit port leaps to the upper surface between the upper pairs of gusts 40a and 40b, resulting in an area that flows into a more stable and stronger thin layer.

As the gusts move downwards until the gusts are immersed, the size of the gusts increases, so that similarly thin areas generally have a triangular shape.

This fixation also occurs at low pairs of whirlwinds.

When the flow of the injection port proceeds downward, the whirlwind tends to lose the same thing as the whirlwind, as by the cross section of the air coming from the injection port J ³ shown in FIG. After the blast has been immersed, the flow of each outlet until it has a greater kinetic energy per unit has infiltrated the periodic flow to create an area of interaction as described in detail in the above-mentioned French Patent Publication No. 2233318. It is compared with the kinetic energy per unit amount of periodic flow 15 which can impart the flow of the injection port.

It is noted above that the region is characterized by a pair of rotating whirlwinds 42a and 42b (FIG. 6).

In the area where the second injection hole penetrates the main stream, each flow and velocity of each of the second injection holes is sufficiently concentrated adjacent to the axis of the injection hole to give each injection hole acting individually. It remains and forms a separate area of interaction with the periodic flow.

A second blowing port (J ¹ , J ² , …… etc), each of the fiber forming centers forming the fibers, to give practical use of the flow of the exfoliating material (especially the outflow of glass fibers), whirlwind It can be obtained from conducting a valve of fiberglass G formed at the outlet of tip 36 towards an area in which an injection port located between the upper pair of laminar flows.

This characteristic, which flows on the top of the current transformer bar 19, produces very strongly inhaling air, as is the flow of injection port J ² shown by arrows in FIG. 6 and FIG.

The aspirated air promotes the thinning of each valve G towards the outflow of the fiberglass and the stable conduction of this outflow towards the area flowing in a thin layer located between the two pairs of whirlwinds formed at each fiber forming center. do.

Therefore, this swirling air stream carries this runoff away and begins the process of drawing this runoff towards the fiber, as shown at 38 in FIGS.

The flow of the inlet port separates the entry of the partially elongated fiber passing downstream into the mainstream 15, and the incidental and rotational winds 42a and 42b in the incidental anti-rotational sensation that effectively effect tapering. Conducts these fibers into the area. Therefore, this fiber is concentrated by an engine such as the cone bearing valve 2 and the guide channel C 'shown in FIG.

Even though the elongation at which the injection port flows can be used to produce the fibers without the aid of the main stream 15, it is desirable to consider the tapering effectively effected by the injection port performing the first elongation. It is also desirable to carry out a second stage elongation in the area of the interaction with such an air stream.

The technique described above is preferred for use by the organ to separate the major elements of the fiber forming apparatus (especially generators that taper the source and periodic flow of glass fibers), but more preferably separate the rat from the ejector spinneret. Therefore, the transfer of heat between the machines is reduced, so that when the machines are spaced apart from each other, it is very easy for the engine to maintain each element of the machine at the required temperature.

However, in such a fiber forming apparatus, it is important to elongate the main stream at a very precise location and to conduct the exudation of the elongable material into regions of individual interaction.

Despite separating these elements, the invention improves the pairing of whirlwinds at each delivery spout made to make it possible to obtain a very stable flow, so that the conduction of thin materials is accurate and accurate Equipped. It is to be noted that the apex of the whirlwind is located on the surface of the cylinder bar 19 and "attached" to this surface in this stable position.

Therefore, if the peak of the fan is located in the free space, the fan can be more stable than the fan is located. As a result, it is very stable to conduct thin material into the region of interaction.

Furthermore, in the event of a slight deficiency in which the valves of fiberglass G are arranged horizontally in connection with the corresponding orifice 32 of the ejector spinneret, this deficiency is a thin layer located between the upper vents of the ejection vents. Similarly, due to the airflow of the air sucked in, the parallel flowing areas may be automatically negated.

This makes the delivery of glass fibers very similar to the thin layers obtained at each injection port, which makes the delivery of glass fibers very stable, and also improves the stable conduction of glass fibers to the second stage of interaction. Is the result.

Although improvements in thin-layered areas can impart an inflow of stabilized glass fiber outflows at each fiber-forming center, changes in operating conditions over time require changes in interaction, It's where it works, given the changing component of the center.

The machine required to effect such a change is described above in connection with FIGS.

In addition, some examples of this machine, for example screw jack 26-27, trachea or sockets and trachea of screw 30-31, are not controlled by any control without inhibiting the process of fiber formation (e.g. The 34 parts allow for the manipulation necessary to adjust the position of the current transformer bar 19 in conjunction with the injection orifice.

However, it is possible to arrange all regulators in such a way as to operate the regulator while continuing the process of fiber formation. Changes and possible separations relate to the drawings of FIGS. 13 to 22, which have also been described in detail.

FIG. 10 is a cross-sectional view similar to the three main elements of FIG. 5, three of which are a periodic flow generator, such as a cylinder current transformer bar 19, a second outlet spinner and a source of elongate material. Figure 10, such as sections 10a and 10b having the same symbols in area and angle, relates to the table below showing the change in area and the appropriate range of change in angle and also the preferred values in the table.

TABLE I

TABLE II

When the axis of the exit spherical orifice is tangent to the top surface of bar 19, 1 _JD is 0, and a negative value of 1 _JD corresponds to the case of FIG. 10 where this axis ends in the upper part of the bar.

TABLE III

TABLE IV

_Looking at the symbol X _BJ , the negative (-) value corresponds to the case of FIG. 10 showing the outlet of the nozzle radiating the main stream located above the second outlet orifice observed in the direction of the main stream delivery. .

To specifically illustrate what is shown in FIGS. 1 to 10b, the second or port outlets collide and spread over each other to create a pair of whirlwinds at each port, all arranged sufficiently close together. To prepare.

When creating many of the desired fiber-forming centers, each center has an injection port associated with a supply tip supplying elongate material, but in order for each injection port to collide with each side of the adjacent injection port, The number of s is also two revisions larger than the number of supply lines, and two "incident" outlets are arranged at the end of each line.

The word "feed orifice" required for elongate combustibles is a very general meaning and refers to either an orifice or a plurality of orifices or grooves or isolated orifices connected to a plurality of feed ends. When the tip is replaced by grooves arranged laterally in the main stream, the material conducted from the grooves is divided into the nucleus and the outflow by the action of the injection port.

For the same reason obtained earlier, two additional injection holes are located at the end of the row of injection holes.

Although the number of fiber forming centers is close to 150, for the fiber forming apparatus required for organic fibers or similar thermoplastics, suitable bushings have 70 feed ends and 72 injection holes.

The present invention also mentions that the operating state of the engine according to the invention changes with the action of changing elements, such as the properties of the material being converted into fibers.

As described above, the present invention is suitable for a wide range of elongateable materials. In the case of glass fiber or inorganic thermoplastic materials, of course, the temperature of the bushing or source of material will vary depending on the material being converted to the fiber and is generally within a temperature located between about 1400 ° C. and 1800 ° C.

In the form of conventional fiberglass composites, the temperature of the bushing is in the region of 1480 ° C.

Unit pull rates vary from 20 to 150 kg per 24 hour aperture, with typical values ranging from 50 to 80 kg per 24 hour life savings.

In addition, it is very important to use the following symbols as shown in the following table for the values related to the injection port and the main stream.

TABLE V

Table VI

11 to 12b, the specific representation of this figure is similar to that of FIG. 6, but in FIG. 11, the periodic flow 15 is radiated, and the portion associated with the injection port flows is shortened.

The main difference between this and the first specific representation is that the current transformer devices are located in parallel. This figure has a continuous channel in the upper part and the lower part through which the injection port flows along the entire length of the bar in the case of cylinder bar 43 (preferably cylindrical cylinder bar, with a vertical flange).

Each element 43α, 43β, 43γ of the bar formed by the flanges clarifies the channel at the corresponding outlets J ₁ , J ₂ , J ₃ , respectively. As can be seen in the drawing, each successive element has a plane symmetric to the plane formed by the thin material outflow and the axis of the outlet orifice.

Although the process is similar to that described above for the first embodiment and above, each of the wind turbines is blown against the sidewalls of the flange 44 by impinging a pair of whirlwinds by colliding adjacent injection holes against each other and not spreading. Create a pair.

Therefore, this flange helps to stabilize the peak of the whirlwind, and this factor is of great importance for the above-mentioned reasons, especially in the individual areas where the injection holes interact, despite the large gap between the major elements of the fibrous organ. It is very important to ensure that the spill of material is accurately conducted.

Since the improved pair of blasts combined with the delivery outlets do not require adjacent outlets to impinge on each other, the lateral spaces between the fiber-forming centers and the lateral spaces between the current delivery outlets are larger than in the first case. have.

This form is beneficial for the fibrous formation or treatment of varying materials that are desirable to maintain greater spacing between the elongateable materials of the feed orifices.

12 to 12b showing the relationship between the area and the area of the major elements of the fibrous organ of FIG. 11, which are the same as those entered in Tables I to VI, most of which are associated with the first specific representation. .

The diameter D ₁ of bar 43 is equal to the diameter of bar 19 of the first example (Table II) while the flange 44 has the area shown in Table VII below.

TABLE VII

The spacing Y _J between the outlet orifices 23 is preferably slightly larger in the second specific representation because the flange 44 is present in the thickness of the current transformer bar and the current transformer bar.

Furthermore, if the flanges are positioned appropriately on the current transformer bar, they impinge adjacent ejection openings on each other so that a pair of gusts spread or impinge the individual ejection openings against the side walls of the flange in the case of non-spreading to create a whirlwind. Therefore, there is no limit to the upper part in the interval between the injection holes.

However, it is preferable that the spacing between the injection holes correspond to the spacing between the flanges, which generally says that two adjacent injection holes are separated by only one (thin flange). This spacing has a value larger than about 5 mm.

The areas shown in FIGS. 12 through 12b are the same as in Figures 10 through 12 and different from those associated with Tables 1 through IV. The second specific representation is beneficial not only in cases where it is necessary to have significant spacing between adjacent fibrous centers, but also because the flange prepares each fan peak of greater stability.

Indeed, in the first case this vertex is stable not only at one of the busbars in parallel at the position obtained at the circumference of the bar, but also at the position obtained along this parent (generally in parallel with the sides of the flange). It is stable at.

Observing the second specific representation, the position of the radiating orifice 32 relative to the second outlet in relation to the current transformer bars (19 and 43) represented by the gaps (Figures 10 and 12, Table II) is It is as if the flow of the exit port is subdivided into two parts flowing along the opposite surface of the bar.

Furthermore, the bar is replaced in close proximity to the axis of the radiating orifice with respect to the carrier injection port in order to deform the rat from the original furnace.

However, the deflector bars can be arranged because they only deflect the flow of the injection machine locally, thereby forming upper and downstream parts of the same strength, which are downstream of the bar without limiting the exit of the injection port. To fuse continuously. In this case, the area of the pair of whirlwinds and the thin layer flows until it is formed, but not tapering at the exit port.

Theoretically, it is possible to arrange the individual injection holes since the whole flow passes through one axis of the bar, but it is suitable for the preferred form of the present invention because the angle requires maximum stability as the flow leaves the surface of the bar. Not.

If the entire stream passes through one axis of the bar, the deflection angle at the exit of the bar and the exit port is not recognized but subject to fluctuations and under the nutrition of the extremely parasitic air stream.

This results in irregularities that occur when tapering at the exit or tapering in the area.

Therefore, the value for 1 _JD is preferably selected because each _injection port flows on both sides of the bar, but the injection port flows at a larger rate passes through the bar along the surface present in the outflow of the thin material.

In discharging the flow, this heterogeneity imparts a pair of whirlwinds 40 and 40 obtained closely to supply a thin material to become larger and more powerful than the pair of whirlwinds 41a and 41b produced by the flow around the opposite side of the bar. can do.

This arrangement is very clearly advantageous when it is required by the preferred form of the invention. The need to deploy is when: This is when the thinning of the fiber requires the effective domination of the pair of gusts 40a and 40b.

Specifically depicting this figure, the mechanism not only gives the adjustments obtained with the mechanisms of Figs. 1 to 12 to make it easier to perform, but also performs another form of adjustment to perform as described in the specification. Grant.

References were first made to FIGS. 13, 13a and 14. Perforated conveyors of the same type were marked with 20 as shown in FIG. 1 to aggregate the fibers. The perforated conveyor is connected to the suction chamber 21 which is connected to the suction pipe 22 to assist in the placement and deposition of the fibers.

Melting furnace for supplying a plurality of bushings 52, which is one of the larger magnifications shown in FIG. 13, as shown in FIG. 14 showing the arrangement of fibrous formations A, B, C and D of the fifty-four auxiliary instruments. It supports 51's fore hearth.

In each fiber forming section, the mechanism has varying elements to create multiple fiber forming centers. Each part has one bushing 52 located perpendicular to the plane of the drawing, and one bushing 52 equipped with multiple feed ends to form the outflow of valves or molten material.

In addition, each part has a main stream connected to each branch pipe having a plurality of outlet outlet pipes 56 and a plurality of consecutive outlet hole radial refills 32, as shown in part in the cross-section of FIG. Have at least one generator that produces 15. In addition, the sectional drawing of FIG. 13A showed the form of the current transformer flap 57 fixed to the injection port branch pipe by the screwo 57a. The action of the flap 57 at the injection port J is shown schematically in the same drawing.

The fibers 38 produced at each fiber forming center are simultaneously produced in adjacent fiber forming centers and are conducted in channel C 'at the same time, so that all the fibers flow all over this channel to be continuously deposited in the form of a fiber B's mat.

The nozzles 55, the outlet branch 56 and the current transformer 57 or more of the generators mounted on the rat are equipped with a whole array of changing control mechanisms and mechanisms. By forming, it is bonded to each other at each fiber forming portion. At this end, one of each section has a vertical suspension rod 58 that is connected to the striker 50 that assists Pooh's 51.

The lower end of the suspension rod 58 (FIGS. 13, 14, 15 and 16) carries the cylinder sleeve 59 on an axis transversely spread over Poohers, in which the fiber forming part is parallel to the bushing 52. . Suitable for the sleeve 59 is a journal 60 in connection with a flange 61 carrying a counter flange 62 in rotation in fixing the designed support 63 for carrying the fiber forming device in each section.

This flange 61 is a curved stop plate 64 located between the locks 65-65 completely attached to the sleeve 59. The sledge inserts an adjusting screwo 66 with support 63 shifted about the axis of sleeve 59 and journal 60. Both flange 61 and counter flange 62 are closed and held in a controlled position by screw 67.

The movement of the fiber forming apparatus, the main flow generator, the spinneret 55, the branch pipes 56 for the injection port and the condenser 72, although they move at an angle with respect to the axis of the sleeve 59 and the journal 60, are significantly spaced above their axes. It is located at this location so that it changes this part away from or facing bushing 52 and the outflow of fiberglass.

Since the whole fiber forming mechanism is installed in support 63, all elements 55, 56 and 57 are thereby able to replace everything facing or facing simultaneously at the same time away from the outflow of the slender material from the bushing 52 to the fiber forming section. do.

The other device and the regulating device will carry the support 63 shown in FIG. 13 and FIG. Flame 68 is therefore mounted on this support 63 and is preferably mounted by slide 69 which can be replaced and adjusted on the right or left side of FIG.

The gas concentrator 72, which supplies branch 56 to the outlet, is associated with other elements of the engine, such as the mainstream generator and organic fiber source 52, in order to adjust the position of the concentrator 72, branch 56 and current transformer 57. A device (shown by 73) for discuring or fixing the device is installed in the generator necessary for the periodic flow.

The movement of flame 68 in connection with the support 63 to move the current transformer 57 away from or toward the main flow nozzle 55, the outlet branch 56 and the bushing 52 is shown in FIG. It is shown graphically.

One of these engines has an intermodal representation of the Mac 74 and the other Jack 75 in a cylinder and piston arrangement. Both bodies 74 and 75 are connected to flame 68 in such a way that they can act on flame 68 independently of another one.

The piston of the jack 75 is connected to a stroketure equipped with a main flow generator and an outlet port branch line 68a in FIG. This figure also shows that the condenser 72 is connected to 76 supplying the fluid. Prepare a cylinder of jack 75 on one end of the jack, with connector 77 passing to the distributor valve 78 connected to the other end of the cylinder by connector 79.

The regulated fluid for jack 75 is stored in tank 80 connected by pipe 81 attached to valve 78 and pipe 82 attached to supply line 76 supplying fluid to the outlet branch.

In this line, a pressure sensitive detector 83 regulates the multiway distributor valve 78.

Detector 83 with a manometer is connected to a Circuit 83 with a control solenoid 83 for valve 78.

The detector is also used to adjust the circuits 84a and solenoid 84b close to the electronic valve 84 located in the pipe 82 between the tank 80 and the supply line 76. The other position of the distributor valve 78 discharges the fluid.

In the position shown in FIG. 18, the valve is opened to supply a regulated fluid (e.g. compressed air) to the pipe 79 which is connected to the piston at a lower position from the tank 80, which is generally close to the bushing. It refers to the position on the main flow generator and branch pipe with respect to the injection port located.

Therefore, pipe 77 connected to the lower part of the cylinder is connected to the atmosphere by way 78e. This arrangement can be achieved by the solenoid 83b when the chamber 83 adjusts the average pressure condition on line 76 to supply gas to the outlet. In the event of obstructing the flow of the outlet or excessively reducing the supply pressure of the outlet, this detector 83 is directed to the distributor valve 78 by the solenoid 83b as the pipe 79 connected to the upper part of the cylinder delivers to the atmosphere passing through the outlet 78e. Deflect.

At the same time, this piston is replaced in the tank 80, as this piston is placed on the upper side, as shown in the drawing or in the direction which causes the rapid recovery of the generator and the injection engine to move the piston away from the bushing. The conditioned fluid is discharged past pipe 81 towards the connecting tube 77 attached to the lower part of the cylinder.

The electronic valve 84 at 82 in the supply pipe of the tank 80 is also intimately connected by Solade 84b when the detector 83 adjusts the pressure drop in line 76 to supply gas to the outlet.

Therefore, the limited stockpile of the regulated fluid always enables the main flow and the injection port away from the fiberglass feed bushing whenever it interferes with supplying the fluid to the injection port.

It will be appreciated that the purpose and benefits of this organ are simultaneously fibrous formation, with the branch pipes for the mainstream generator 55, the outlet port 56 and all the current transformers 57 (shown in Figures 13 and 17) bushings. All are located in close proximity to the outflow of molten material conducted from feed end 36 of 52.

The presence of a smoothly flowing injection port provides a suitable and stable supply of thin material outflow, but if the injection port is obstructed or the supply pressure of the injection port drops to an unusually low value, the flow of the injection port will It will no longer be possible to maintain the outflow of material in the relative position required for the current transformer 57. Therefore, the molten material is likely to fall into the current transformer, outlet branch or main flow generator and possibly damage one of these elements.

Because high temperatures are required to supply the material in the molten state, bushing 52 is used and deforms over time, and it should be noted that this deformation occurs in either a vertical plane or a horizontal plane. It tends to have a variable current effect on the exact position of the current transformer 57 of the interaction and the apex of the glass fiber feed tip 36.

Therefore, for the sake of concrete representation in FIGS. 19 to 27, these figures are provided with bushings suitable for modifying the rat and the relative position of the trachea 57 with the appropriate action or interaction.

As can be seen in FIG. 19, the single deflector 57 is the total length of each successive five adjacent branch pipes 56 connected to the feed conduit 1 attached to the connected piece 12. Lined up. The conduit 113 is mounted as free movement in the direction away from or toward the bushing 52, for example on the roller 113.

At least three branch tubes 56 can be moved separately as a conduit with the roller. To this end, each of the three center feed conduits 111 is transversely movable, as shown in the right tip of Figures 19 and 21, and an oblique hole formed in a separate plate 116 spread across the edge of the mechanism. For use in the obliquehole 115 it has a pin 114 pointing upwards.

Each plate is at a brace 117 square end pierced by a used dismantling grooved in a rod 118 screw that carries the screw-nut on each plate 116 located separately.

Therefore, the branching tube combined with the position of the conduit 111 is adjusted differently from each other in the horizontal plane, which means that the apex of the feed end 36 is tilted upwards and the branching tube is tilted towards the position where the deflector flap 57 is slightly tilted. Fig. 27 is a diagram illustrating the deformation of bushing 52, such as pushing a branch pipe.

The condition shown in FIG. 27 is greatly exaggerated and in fact the current transformer is only slightly tilted. The branch pipe is also replaced by the opposite point to correct the opposite deformation of the bushing as indicated by dashed line 52a in FIG.

It also has the relative movement of the three central branch pipes 56, which correct for the deformation of the bushing in the vertical plane. For this purpose, each feed conduit 111 can adjust the transverse shaft 21 by rotation and then surround the cam 120 mounted on the transverse shaft 21 which can be fixed by a nut 122 (screwed with a screw). It is equipped with 119 elements of the u-shaped form.

The three central branch tubes can therefore be moved slightly upwards or downwards to achieve a slight inclination of the deflector flap 57 and slightly upwards or downwards to correct for the deformation of the bushing in the vertical plane. This adjustment is illustrated graphically in FIG. 26, which again greatly exaggerates the strain size of the bushing. These elements 119 and 120 are used to direct the relative movement of the branch pipes to the top or bottom, as indicated by the straight and dashed lines 52b. Of course, the elements described in FIGS. 19 to 27 used in a tilted injection machine current transformer are very different from those described in FIGS. 13 to 18.

28th

Specifically described above in connection with FIGS. 1 to 28, each fiber-forming center has four components: a main flow generator, an ejector spinneret, an injection port for creating a low pressure stable zone. A device, such as a current transformer, located along the furnace, and a glass fiber source positioned to conduct outflow of the glass fiber in a slender state to a low pressure area (such as what is known as a thin layer flowing area) of the injection port.

In addition, each of the three fibrous components has the meaning of setting up the fiber fiber forming center and having at least one adjustable device that changes the position and operation of the current transformer device in association with at least one of the other components.

In other words, the various regulating or regulating devices are capable of changing at least one of the relative operating positions or interactions of the current transformer device and other components of the fiber forming center. What is specifically shown in FIG. 28 does not have a current transformer device, so the fibrous center has only three components. This device is inconsistent with the various controls having similar meanings as described above to alter the position and interaction of at least one of the three components in connection with two others.

It is very important that FIG. 28 that this adjustment is made effective in the plane with the axes of the exit spout orifice and the fiberglass spun orifice.

Some parts of the device are particularly similar or identical to those shown in FIGS. 13 to 18.

Therefore, the vertical suspension rod 58 is connected to the auxiliary airflow 50, which is equipped to assist the fore hikes and bushings 52. The suspension rod 58 carries the flange 61 with the auxiliary slab 59 and the journal 60 at the lower end of the suspension rod in order to be able to make adjustments to carry in connection with FIGS. 13, 15 and 16.

Such a machine may carry a beam or flame 90 which assists the mainstream generator, flag, feed conduit 91 and branch tube 92. This branch may be the same as the branch of FIG. 4 or 13, but this branch does not have a current transformer 19 or 57, and the exit spout orifice 32a has an exit spout downstream of the glass fiber feed orifice of the bushing 52. It is positioned and oriented as in FIG. 28 showing what is being emitted. The injection port penetrates the main stream, and the enclosed air or gas, which slowly exits as the injection port, causes the outflow of glass fiber for inhalation into the injection port, as described in patent application no. This is because interactions carry this runoff into the region as the main stream, which is mainly subject to being. Instead they are located in relation to each other, such as in French Patent Application No. 7504970, which describes the direct entry into the area of fibrous interaction. Plate 93 in support 94 has a bore in the form of a groove coinciding with the screw engine 95 for closing the plate in support 94. This arrangement can give the installed periodic flow generator 71 because the plate can be moved away from or towards the bushing in the horizontal direction. This arrangement also has the possibility of fixing the mainstream generator at the position obtained or leaving the mainstream generator moving in accordance with the operating state (eg as easily described in FIG. 17).

In the same manner as described specifically with the mechanism of FIG. 13, a manual or automatic adjustment machine, as shown in FIGS. 17 and 18, may be used to move a manual or automatic adjustment machine away from or toward the axis of the glass fiber feed orifice. It does not coincide preferably with the apparatus of FIG. 28 which gives the position of the generator and the branching pipe for regulating. This control can automatically adjust for lack or anomalies in supplying gas to the outlet.

The screw jack 96, which is required for mounting the main stream 71 on the plate 93, can give the position of the regulated main stream generator in the vertical direction. An element 97 similar to that of FIG. 13 installs a branch tube 92 connected to the main flow generator screw jack and a feed conduit 91 connected to the injection port.

This element makes it possible, in particular, to fix the ejector spinner at a position associated with the mainstream generator or to move the collector 91 horizontally, and / or if this element is prepared as appropriately adjusted. Such is possible at the position associated with. In such a manner as specifically describing the apparatus of FIGS. 13 to 18, a machine having a fiber forming center is installed in an auxiliary device that assists or is connected to a source of glass fibers.

General assistance to the source of fiberglass and the fiber forming device is desirable because the outflow of the glass fiber promotes the positioning of the fiber forming device in conjunction with the bushing or bushings from being conducted to the fiber forming center.

The above-described mechanism for performing the adjustment in various forms can be replaced by other organs that perform the same action.
