Description

201111572 VI. INSTRUCTION DESCRIPTION: Patent Application No. 093107628 [Technical Field of the Invention] The present invention is a division of the invention of the Republic of China (93.03.22). SUMMARY OF THE INVENTION The present invention is directed to a use of a ^ ^ έ * m _ a type of ablation nozzle for use in unwinding v. The converging nozzle has a through-passage passage through which the compressed air is blown into the yarn passage in a direction in which the yarn is conveyed, wherein: the outlet end of the passage is greater than 1 G. The angle of expansion is (and preferably tapered) widened. For winding the endless yarn winding method (4), a through yarn passage is provided, the yarn passage having H, a middle portion (preferably cylindrical and having a 'air blowing hole), and a The outlet section 'the outlet section is preferably tapered and has an expansion angle greater than 1 〇. But less than 4 inches. . [Prior Art] "Textureren" - a part of the word still refers to the spun filament bundle or related endless yarn refining (Veredelung), the purpose of which is to impart a textile characteristic to the sigma yarn. In the following description, the term "collection" refers to the creation of a majority of loops on individual long yarns (Schlingen, English: loop) or the creation of a ring crepe (Schlingengarn). An older solution for the collection is found in European Patent EP 0 088 254. The endless filament yarn is fed to the yarn guiding passage at the inlet of the winding nozzle ☆ and is wound by a supersonic flow at a flared outlet end. The middle section of the yarn guiding passage has a cylindrical shape with a constant cross section over the entire length. The entrance is slightly rounded and the untreated yarn is introduced without problems. There is a guiding body at the flared outlet end, wherein 201111572 forms a ring (loop) between the octagonal ridge and the guiding body. The yarn is fed to the winding nozzle with a large overfeed. To make a circle on each individual long yarn, this super-weakness must be such that the titer at the exit end is increased. This European patent Ep 〇〇 88 254 is started by a winding device for winding endless yarns consisting of a plurality of long yarns with a nozzle for pressure medium, β containing __ yarn The guiding channel and the at least one supply medium of the pressure medium are opened radially into the channel. The outlet opening of the passage of such a nozzle widens outwardly and has a spherical or hemispherical guiding body projecting into the outlet opening to form an annular gap therewith. It is known that in the case of a winding yarn, the property k of the yarn to be obtained after the processing time is an important criterion for the usability of the yarn of the final product, and in addition, the mixing degree of the two or several yarns is high, And this combination of individual filaments of the web is important for achieving a uniform fabric texture. In & 'stability is used for the quality index of the work, to determine the yarn instability (I), the yarn strip (with four windings, each with a circumference of one meter) on the - reamer shape & , as shown by the multifilament yarn of 167868dUx #聚(10). This sliver was subjected to a load of 25 cN for one minute, and then the length X was measured. Then, the same load of 125 cN was applied for one minute, and after the load was released, the strip was again subjected to a load of 25 cN after one minute, and the length Y was measured again for one minute. The value of instability is obtained as follows: γ υ I = ¥.100%

JC This instability indicates how much of the 201111572 residue is pulled due to the applied load: °EP 0 088 254 is intended to provide the best type of improved device II of the above type to ensure optimal winding effect to ensure The yarns are highly stable and have a high degree of mixing of the individual long yarns. The solution is to make the outer straight pinch of the convex bulge outlet opening of the channel at least four times the diameter of the channel and at least equal to twice the diameter of the spherical or hemispherical guiding body (5). The best fruit is found at production speeds ranging from 100 to over 600 m/min. It is worth noting that the applicant has successfully marketed the relevant nozzles for more than 15 years. The quality of the yarns produced in this way has proven to be very good over the course of fifteen years. 'But the demand for increased efficiency is growing. This solution has increased the efficiency to over 1000 m in the solution in EP 0 880 611. Minute. The central idea of efficiency improvement is to densify the nature of the gas flow in the widened supersonic channel, in other words, in the region where the lap occurs. The special test standard is the tension at the exit of the nozzle. The multi-test series of standby time shows that in the solution of EP 〇 〇 88 254, the banknote tension is about 600 m/min. The yarn delivery speed is greatly reduced. This concludes with a description of the limits of the power of this type of nozzle. The manner of having Ep 〇 88 〇 254 which densifies the air flow in the supersonic channel causes the yarn tension to be unexpectedly increased, so that the transport speed is increased to over 1,000 m/min. The quality of the yarn thus processed is still the same or even better in evaluation even at the highest conveying speed. However, the practical results are unexpected, because in many applications, the quality of the yarn does not meet the demand. SUMMARY OF THE INVENTION It is an object of the present invention to provide a winding nozzle which provides for efficiency, particularly in the direction of more than 1 mm/min, but still maximizes the yarn quality of all 201111572 applications. [Description of the Invention] According to the invention, the air-reducing system is greater than 48. (In the special yarn channel. The blowing angle used to intensify the spinning action is greater than 50°), the blowing angle is blown into the study at all the 7ths. Only one point can be confirmed: for "treatment air", the best The blowing angle of the data obtained by the Ep (four) 88 254 winding nozzle is 48° over 48. It will only make the contraction worse. You can also refer to A. D-r in 1 " February of the year (Μ _ ) in "Journal 〇f

Englneerinf for Industry,, a masterpiece of research. The authors of this topic use the Xu Xi research series to examine important parameters. Here you use 3〇. , 45. And. Nozzle test for blowing angles. In all respects, with 60. The blown angle of 0 is worse because it is at 6G. Most of the energy goes to the opposite wall and turns into an island. Therefore, it is economically confirmed that the conclusion of the nozzle according to EP "88 254: Lu’s development of the mouth, and therefore no longer questioned, the development of the newer nozzle type in EP 0 880 661 There is no reason not to abide by this experience that has been confirmed over the years, that is, the blowing angle is 45~钧. The range is the best. Therefore, this specificity is still taken in the operation of the EP〇88() 611 solution. However, as far as the impact of the angle of influence is concerned, it is a new approach to improve the quality of the yarn. Unexpectedly, we found that the nozzles of EP 880 880 61 1 increased the blowing angle, and in the first series of tests, the quality of the wound yarns was unexpectedly improved. As a result, the inventors have known that the two program areas 7 201111572 - the opening operation - the yarn winding operations must be optimally matched to each other. Repeated tests have shown that in the solution of EP 0 088 254, the limitation is in this region of the winding, so increasing the yarn opening effect only leads to unfavorable results. In the field of yarn entanglement (Verwirbelung, English: entangnng), it is known that the opening effect is maximized when the angle of blowing is 90. The purpose of entanglement is to form a regular knot in the yarn. For examples of entanglement, refer to DE 丨 95 8 〇 ^ 9 ^ and in the case of a web, on the contrary, no knot is formed. For the two fundamentally different methods of forming a knot and forming a loop, the blow angle must be set to a limit. However, it is still impossible to determine this limit. So far, the range of the blowing angle is 49. , but less than 80, and special & 5〇. ~ about 7 baht. . The upper limit is still not finally accurately obtained. The yarn passage has a central portion, which is preferably a circle (four), which gradually transitions to the tapered wide portion along the conveying mode, and there is no sudden enlargement and smallness therebetween, wherein the I-reduced air is changed from the taper to the taper. The supersonic channel is blown into the cylindrical section at a sufficient distance. In terms of the research aspect of the present invention, three new cognitions are mainly provided: • When the density of the convoluted supersonic flow according to EP 880 880 661 is increased, the angle of the nozzle increases to more than 48. , the quality can be improved in various yarn deniers. • When the angle increases by more than 48. At the time, the quality began to increase significantly. The angle of the field is greater than 52. At the time (partially reached 6〇., even 65), the yarn quality was surprisingly constant. However, the optimum blowing angle is also related to the yarn titer. 201111572 Therefore, it is proposed to determine the blow angle as a function of yarn quality. Especially at 48. ~8〇. (and especially 5G. ~7().) The function of the fineness of the yarn in the circumference. The advantages of the present invention can be utilized in a convolution nozzle having only a single orifice through which compressed air is blown at an angle greater than 48 or 5 inches, but preferably the compressed two gases are separated by two i 2 The bore of the crucible is blown into the yarn passage. In any case, it is important that the I yarn action is densified by the blowing of compressed air into the yarn passage, but the formation of knots in the yarn can be avoided. The drip nozzle of the present invention is characterized in that the compressed air for densifying the yarn opening action is greater than 48. The blowing angle (and preferably greater than 5 。) is blown into the yarn passage. Preferably, the air blowing position is located in the cylindrical section at a distance from the conical widening section, and the distance is at least approximately equal to the diameter of the yarn passage. According to the current knowledge, the two The program phase - the length of the opening and the winding phase - the nozzle of the previous EP 0 088 254 is too short. This is also one of the reasons for using these old solutions with limited shipping speeds. The invention opens up different cognitions: 1. The yarn opening operation and the yarn winding operation are separately optimized separately; 2. To optimize these two completely different functions, their locations must be separated; 3. However, the ministry must be implemented next to each other so that the yarn-making operation is followed by the winding-up operation. Or, immediately after the opening of the yarn-drawing operation, the paper is directly entered into the winding operation. The central cylindrical section of at least one of the nozzles and the tapered widened outlet section are designed as part of the nozzle core. The nozzle core should be designed to be 201111572 and made of a material that is resistant to wear (especially embedded in a nozzle tip, which is a ceramic). It is particularly advantageous to design the mouth core as a replaceable core

point. - As is conventional in the art, a guide body is provided at the exit end of the tapered widened section to at least all the way to the tapered widened outlet section attachment. This further promotes the constant quality of the yarn. The tearing nozzle is preferably designed as part of a winding head in which the air distributing elements are provided in three air blowing holes in the winding head. For further details, refer to Ep 〇 88〇 61丨, which is the basis for the initiation of this invention (if the program phase is related to the conclusion of the volume). As mentioned in EP 880 880 61 1, the first key is the banknote tension after the nozzle is wound. Only by increasing the yarn tension can the quality be improved. This breakthrough can only be achieved when the blown air stream refers to a range of more than 2 Mach. Many research series have proved that not only the quality is improved, but also the negative impact due to the improvement of production speed and quality is surprisingly small. The Mach number has only slightly increased by more than 2 and has obvious results. The best explanation for the associated densification of the book-breaking process can be seen by the fact that the difference in velocity between the front and the back of the "Stossforont" is increased. This is directly for the air to be clamped to the filament. The associated clamping force has an impact. The strength increases in the area of the impact front, which increases the yarn tension. By increasing the Mach number, the situation in which the impact front occurs is increased. According to the present invention, the following law can be known: a higher Mach number = a stronger impact = a denser collection operation. The dense supersonic flow creates a wider front and makes the filaments of the 201111572 open and V denser, so there is no loop that deviates from the side beyond the impact front. Since the generation of supersonic flow in the accelerating channel is based on expansion' so we utilize a higher Mach number range, e.g., without Mach 1_5, Mach 2.5 can also increase or nearly increase the effective exit cross section. There are various unexpected observations in the context of the present invention, and together with the present invention confirms the idea of the invention: although the supersonic channel designed for the higher Mach range is used and older; the technology is 'the same The quality of the windings is improved at the production speed. A pair of individual yarns were tested for production until the production speed was 1 〇〇〇 to 1500 m/min without disintegrating the winding effect (Zusammenbruch). Immediately in the measurement technology, the average yarn tension rose to 50%. Moreover, in a large speed range, for example 4 〇〇 to m/min, this rise value remains nearly constant. - In addition, it does show that there is a major influencing factor in the choice of supply pressure of compressed air. In order to ensure a higher Mach number, in many cases, a higher supply pressure is required. This pressure is between 6 and 14 bar but can be raised to 2 bar or higher. A comparative study of the prior art of the European Patent EP 0 0 00 254 and a novel solution of the category EP 0 080 661 yield the following rule in another significant range: at higher production speeds, the quality of the winding quality At least at the lower production speeds, at least the same or better, with a quality of the supersonic channel designed for the lower Mach range. The process of the winding process 201111572 The air velocity in the field of the impact front exceeds that of Mach 2 (for example, in Mach 2, $~Mach 5), so that all the rings can be grasped almost without exception even at the highest yarn passing speed. And perfectly integrated in the yarn. Producing a high Mach range of air velocity in the accelerating channel allows the winding action to be prevented from disintegrating until the highest speed. It is: owed, the entire filament composite yarn is uniformly introduced into the boundary of the clear outer passage and directly enters the impact front area. The original central reference for the positive effect of the present invention is that the stability of the yarn is generally improve. If the yarn that was wrapped with this novel solution is subjected to strong tensile stress and then relaxed, it can be confirmed that the textur, that is, the joint position and the loop, remains almost unchanged. This is a decisive factor for the following processing. _ In the acceleration passage, the yarn is pulled in by the accelerated air jet over the associated path, and the yarn is opened and delivered to the immediately following winding area. The blown air flow, after the acceleration passage, does not steer and is guided through a discontinuous widening and rapidly widening section. One or several yarns can be fed in the same or different overfeeding quantities, and can be used at a production speed of 4 〇〇 to over 12 〆. The compressed air jet is accelerated in the supersonic channel to 2. Bach Mach' and preferably to Mach 2.5. If the exit end of the yarn passage is restrained by a buckling body so that the web is guided away from the yarn passage axis by a gap, the best result is achieved. In a particularly good manner, the blown air is also used in the novel invention. According to the principle of radiation (Radialprinzip), the supply position of a cylindrical section supplied to the yarn passage is sent directly to the speed passage at an approximately constant speed in an axial direction. As in the prior art EP 0 880 61 1, it is also possible to use one or more of the yarns to be wound up in the theoretically effective widening angle of the different super-feeding channels using this novel solution 12 201111572. The diameter of the supersonic from the smallest to the largest is more than 1 〇 ° but less than 4 〇. The general roughness value is 35° to 36 in terms of series manufacturing. , in a tapered acceleration channel 'and preferably at 15. ~3〇. between. At the current upper limit angle (total angle), the compressed air is approximately constant

Speed: the nozzle passage section directly in front of the supersonic passage should be designed to be substantially cylindrical, in which the cylindrical member is blown into the direction of the acceleration passage by the conveying member, and the pulling force on the yarn is accompanied by the acceleration passage. The length of the nozzle and the increase in the variable width of the nozzle or the increase in the Mach number make the winding effect dense. The widening of the cross section of the accelerating channel must be at least 2 〇, and should be 丨; 2 5 or more. In addition, the length of the acceleration channel is straighter than the yarn path at the beginning of the acceleration channel

Private 3 3 times, and should be 4 to 12 times. The acceleration channel may be designed, in whole or in part, to be continuously widened, have tapered sections, and/or be slightly spherical. However, the accelerating channel can also be designed in a subdivided manner with different accelerating regions having a region of greater acceleration of at least one compressed air flow and at least one region of lesser acceleration. Thus, the exit region of the accelerating passage can be designed to be cylindrical or nearly cylindrical, while the inlet region is rapidly widened, but less than the publication. Widening of the angle If the edge condition of the accelerating channel is maintained in accordance with the present invention, the change in the accelerating channel described above is nearly equal or at least comparable. The yarn passage after the supersonic passage has a yarn passage opening which is broadly convex and widened and is preferably flared to be larger than 4 inches. The width is widened, wherein the transition from the supersonic channel to the opening of the yarn passage is preferably non-continuously extending. The factor of m is that the use of a rebound body can also positively affect the pressure in the volume chamber and maintain stability. The preferred design of the crimping nozzle 13 201111572 is characterized in that it has a continuous yarn passage with a central cylindrical section into which the air supply pipe opens and runs along the line. a tapered accelerating passage directly connected to the cylindrical section, the opening angle (α 2 ) being greater than 15°, and having a subsequent widened section, the opening angle (a) being greater than 40〇° Further details are illustrated in conjunction with some embodiments. [Embodiment] Referring to Figure 1, the winding nozzle (1) has a yarn passage (4) having a cylindrical section (2) which is also the narrowest cross section having a diameter d (3) By. The yarn passage (4) gradually transitions from the narrowest cross section (3) to an acceleration passage (11), the diameter of which does not change abruptly, and then becomes widened, wherein the shape of the racquet can be a radius R Definition. The relevant impact front diameter "DAE" can be taken based on the adjusted supersonic flow. According to the impact front diameter, the loosening position or the tearing position A, A" Μ or α4» can be obtained more accurately. For the impact front: the effect can be referred to EP 〇 880 6 Π. The acceleration region of the air also utilizes the narrowest cross section ( 3) The length of the position [a and the tear-off position a is defined. Since this is a true supersonic flow, the air velocity can be calculated therefrom. Figure 1 shows the tapered design of the acceleration channel (11), its length L2. The opening angle α 2 ° is again 20. The release position A2 is shown at the end of the supersonic channel, where the sinuous channel is at an opening angle a > 40. Transition to a non-constant taper of the steep center A Cone % or ° thorn. Eight-shaped widening (12). Since this geometry is formed into the impact front diameter DAE. For example, f, approximately the following relationship: 201111572 L2/ d = 4.2

Vd = 330m / s (Mach i) Dae ~ 2.5 - Mde = Mach 3.2 Extending the speed channel with the relevant opening angle increases the impact front diameter DAE. As far as possible, in the region where the impact front is formed, a "compression impact front" (13) is generated which has a pressure rise region (14) which is subsequently suddenly changed. The original contracting action occurs in the area of the "compression impact front" (13). The air moves at a speed about 50 times faster than the yarn. It can be known from many experiments that these release positions As and A4 can also migrate to the acceleration channel (丨丨), especially when the supply pressure drops, especially, it is practical and can be used for various yarns. The most appropriate supply pressure is given, wherein the length of the acceleration passage (L2) is designed by the designer in consideration of the most unfavorable situation, that is, it is set to be longer. Mb represents the center line of the "blowing hole" (15), Mgk represents the center line of the yarn passage (4), and MgK and

The intersection SM of Mb indicates that the lanthanum is at the position of the narrowest cross section at the beginning of the acceleration channel (1), L1 is the distance between 8] and Pd, and ^ is the distance from h to the end of the acceleration channel (A4). The large Leff indicates the length of the yarn opening area, and the large indicates the length of the yarn winding area. The larger the angle stone, the more the yarn opening area is enlarged backwards. Figure 2 shows an entire crimping head or nozzle head (2〇) with a built-in nozzle core (5). The untreated yarn (21) is sent to the winding nozzle (1) via a yarn feeder (Lleferwerk) and further conveyed in the form of a web (21,). In the sigma region (13) of the winding nozzle, there is a rebounding body (23). - The compressed air connection (Ρ1) is placed on the side of the nozzle head (2〇). The web (21,) is passed through a second yarn feeder (25) at a transport speed VT. The web (21,) is passed through a product 15 201111572 sensor (26) (for example, the name HemaQuaHty), called atq, in which the tension of the web (21,) is measured (in cN units). ) and the deviation of the instantaneous pulling force (S % ), the measurement signal is sent to a computer unit (27). Making relevant quality measurements is a prerequisite for the most appropriate monitoring of the product. This value is also an indicator of yarn quality. In the air-winding procedure, if there is no certain loop size value, the quality measurement becomes difficult. The degree of deviation obtained by the present invention is better than that perceived by the customer as being of good quality. This is possible with this ATQ system because the yarn construction and its degree of deviation can be confirmed, analyzed, and displayed using a single line tension sensor (26). The wire tension sensor detects the wire tension after the nozzle is wound, in the form of an analog electrical signal. Here, the value of Ατ is continuously calculated from the average value and the variation value of the line tension measurement value. The size of the AT value is related to the construction of the yarn and is determined by the user according to his own quality requirements. If the line tension or the variation (uniformity) of the line tension changes during production, the AT value also changes. Where the lower and lower limits are located, they can be obtained by using a goggles, a knitted fabric or a woven fabric. They vary according to quality requirements. The advantage of this ATQ measurement is that different types of interference can be detected simultaneously in the program, for example: positionality of the winding action, long yarn breakage, nozzle contamination, rebound ball distance, hot needle (H〇tpin) temperature, Compressed air difference, POY insertion area (p〇Y_Steckz〇ne), yarn front part (Garnvorlage) and so on. Referring now to Figure 3, which is a preferred embodiment of an entire nozzle core (5), the cross section is multiplied. The external fitting shape (Einpassf〇rn) should be fully compatible with prior art nozzle cores. This is mainly related to the construction material of this critical 16 201111572, the diameter B of the hole. , the total length l, the distance of the nozzle head high-yield joint (.P') ^. Studies have shown that the most I: blown into the ... ° compressed air hole (15) relative to the channel: the separation is very important. Yarn channel (4) in the wonderful entrance area [dry with arrow (10)] = "Yarn introduction cone" (6). The backward direction of the compressed air hole 〇5) is compressed in the direction of the yarn transport direction: the amount "χ" (Fig. 6) indicates that the air hole should be at least offset from the = reading surface (7) by a diameter d. Along the carrying head (10), the winding nozzle (1) or the mouth core (5) has a "yarn introduction tapered portion" (the central portion (7) of the temple-shaped cylinder, and a tapered portion (8) [the tapered portion Although the phase is in the acceleration channel (1)), and a widened volume: the volume chamber is perpendicular to the gas-to-heart shape (10), the dome (1:) core is open to the funnel form. Fig. 3 shows a winding nozzle having three nip holes (1) which are offset from each other by 120. And open at the point Sm of the body into the yarn passage (4). Figure 4 shows a squirting "5) '匕 with a ratio of several times larger than the actual size. The new nozzle core (5) can be used to: replace the conventional nozzles of the prior art The core, especially the inch, the built-in length La+Kh, and Kh should not only be equal, but also can be made to have the same tolerance. In addition, the outer outlet of the shape of the eight-shape; the domain is also made the same as the prior art. 'has a corresponding radius R. The shape of the rebound body: spherical, oblate or even hat-shaped. Bounce in the - phase (4) & mouth area (4) indeed position due to maintaining the external metric (corresponding to - the same pull-off gap Spl ) and always keep the 'volume chamber (10) outward 17 201111572 remains unchanged, but backwards and defined by the acceleration channel (11). The collection chamber can be directed to the acceleration channel according to the selected air pressure The nozzle core (5) - as in the prior art is made of a high hardness material, such as ceramic, hard metal or special steel, and is the expensive part of the tearing nozzle, this novel tearing nozzle The important point is: the circle The cylindrical wall surface (21) and the wall surface (22) in the region of the acceleration passage have the highest quality, and the eight-shaped widening portion can be determined for the yarn friction. Fig. 5 shows an entire nozzle head (2〇), which Having a nozzle core (5) and a rebounding body (14), the rebounding body (14) can be adjusted via an arm (27) to lock the known body (28). To insert the yarn, The rebounding body (14) is pulled away or turned away from the working area (3〇) of the winding nozzle by the arm (27) in a conventional manner corresponding to the arrow (29). The compressed air is made up of a casing chamber (3丨) It is supplied through the compressed air hole. The nozzle core (5) is firmly lost on the casing (33) with a clip strip (32). If the ball is not used, the rebound body can also be a ball cap shape. The left side of the figure shows the prior art winding operation of EP 〇〇88 254 in a schematic manner, where there are two main parameters, an opening area 〇e_ & and an impact front diameter DAS, starting from a diameter d, corresponding to In a spray nozzle, as described in EP 0 088 254, and in the upper right of the figure, the filing operation according to EP〇〇88 61 1 is shown. , 〇e—has a large value with Dae. The opening area 〇e-Z2 starts in the region of the compressed air supply source P not far in front of the acceleration channel and is shorter than the solution of EP 0 088 254 The opening area Oe - Ζ is much larger. The important illustration of Fig. 6 is that the yarn tension of the prior art (curve T311) in Mach number < 2 and the winding nozzle 18 of the present invention having a Mach number greater than 2 201111572 Comparison of the nozzle map of Jinying. In the vertical axis of the order, CN). 扃 also includes a " In the curve Τ 311, it can be seen that the yarn tension drops significantly when the production speed exceeds 5 〇〇m/min. In the case of the smashing of the smashing of the smashing of the smashing of the smashing of the smashing of the smashing of the smashing of the smashing of the smashing Much, and in the range of 400 700: card / minute is almost constant, and even in the higher production speed range is only the wrong team _ =,, friend decline. The increase in the Mach number is one of the most important > numbers for the densification of the volume. The increase in the blowing angle is the most important parameter of the quality of the winding. As shown in the second example, the novel nozzle is used. In this case, the blowing angle is 5 〇. ~60. range. The opening area 0e-z3 is larger than that in the upper right (according to (4) X), and is much more known than the solution in the lower left (according to Ep〇_5). The method parameters of the other program guards are the same in all three solutions. Except 45. ~48. In addition to the range of angles and angles of more than 45, there are unexpected positive effects in the first section of the opening area, such as ΟΖ, and 〇ζ2 marked with or associated with the circle. As shown in Figures 7 and 8, the external difference is only the change in the blow angle. The rising effect of the indicated line tension is above 48. The angle begins, and can only be explained by the combined effect of the inflammatory group. At least for the time being, we know that there is such an unexpected positive result. But the blow-in effect of this 48» is the threshold of the ring-breaking nozzle of the 6". This type of winding nozzle has sufficient power retention. This will result in an increase in yarn quality even if the yarn is slightly densified. Figs. 7a to e and Figs. 8a to 8e are shown in a coordinate diagram in the prior art (T341KJ S345) and the winding nozzle of the present invention at a blowing angle of 5 〇. ~ 19 201111572 ^ The relationship of different parameters. In Figure 8, the line tension increases from about 7 to 56 cN from left to right. The line tension is increased by more than two times in this example. Figure 7 Figure 4 shows that the line tension is less steep. All of the studies so far have been shown to vary among the ranges of the two figures of Figs. 7a and 8Fig. 3, so that the line tension is much higher at the blowing angle of 48 __ or more. Figure 7 c to Figure 7 and Figure 8. ~ Figure 8 shows a different yarn pattern for each of the three volumes. Figure 7 c and the 7th circle "乂 and 8th c and 8d d, the two yarn patterns are used with prior art nozzle manufacturers, wherein in Figures 7 and 8 c According to (4) 〇88 254 (T-nozzle), and in Figure 7d and Figure 8. The middle is manufactured according to EP〇88〇611 (S_nozzle). The pattern in Figure 7e and 81st It is produced in the present invention. In the prior art yarn nozzles, 'these loops protrude farther away' have a plague in a tight position. Value & B2 shows the interval of the most protruding loops Size. The value B3 is significantly smaller in the two lower yarn patterns. But especially in short intervals, very close positions and still dense positions with many loops are also visible. H Qualitative - The point system is that the yarn pattern will behave very differently under load. If the yarn pattern according to the prior art (upper and middle) is subjected to tension, the loop will be loosened too much, and after the tension is released, it will still be partially The ground is loosely dissolving. According to the invention, after the pulling force is released, the loop is still almost completely on the yarn pattern. 2 shows that the quality of the winding is from two aspects. Both can be significantly increased, and this can be used to improve the corresponding use of the present invention = 'the quality and efficiency tP 1 058 745 is part of the overall combined effect of this related 20 201111572. Please refer to the following Figure 9 shows a schematic overview of the novel winding procedure. The respective program stages are continuously displayed from top to bottom. The smoothing yarn (1(8)) is fed from above via a first yarn feeder (LW1) at a given conveying speed νι It is sent to a winding nozzle (1〇1) and through the yarn passage (1〇4). The compressed air passage (103) [they are connected to a compressed air source (PL) to highly compress (and preferably not heat) the air. The yarn passage (104) is blown at an angle α in the direction of yarn transport. The yarn passage (104) is opened in a tapered manner, resulting in a large acceleration in the tapered section (1〇2). The supersonic air flow is preferably greater than Mach 2. As described in the above-mentioned embodiment of WO 97/30200, the shock wave causes an original winding action. The air blowing position (1〇5) enters the yarn passage ( The first segment of the haiku sentence until the first part of the tapered widening (1〇2) A section is used for the flocculation (Aufl〇ckerung) and the smoothing of the yarn. Therefore, the individual long yarns are subjected to supersonic flow. The volume of the air is equal to the ready-made air pressure (9 bar...12 bar until 14 Ba and more) still occur in the conical part (1〇2) or in the exit area. There is a proportional relationship between the Mach number and the winding effect. The larger the Mach number, the stronger the impact, the volume The more intensive the function, the two critical parameters for the production speed: • The required quality standard • The shaking action (Sehlaeken O, which leads to the collapse of the winding action when the conveying speed is increased _steps) (Zusammenbruch). The meaning of the abbreviation in Figure 9 is:

Th. Vor. 'Hot treatment, if necessary, only for yarn heating or with hot steam 21 201111572 G. mech. Flow) Processing with a mechanical action of compressed air flow (supersonic speed)

Th. Nach : Use hot air for heat treatment with hot steam (if necessary, use only heat or D: vapor Pl: compressed air

The production rate can be increased by an additional heat treatment - up to 15 〇〇 m / min without disrupting the winding action and without shaking (Slacken), where the limits are determined by the existing test equipment. The optimum quality of the winding can be unexpectedly at a production speed of well above 800 m/min. The present invention 现 2 now has one or two new quality parameters 'even if the law described earlier (higher Mach) Number = larger impact = dense volume effect) can only be confirmed in all tests. The parameters found were - heat treatment before and after a contracting operation, and on the other hand, by increasing the air pressure and correlating the accelerating channel to increase the Mach number. a) heat treatment or retraction (Relaxieren)

An important quality criterion for the expert to judge the effect of the winding is to use the tension of the yarn exiting the nozzle. This value is also used as the amount of the density of the winding. The tension of the yarn on the web (1 〇 6) Adjusted between the winding nozzle (td) and a yarn feeder (LW2), in the region between the winding nozzle (TD) and the yarn feeding machine (LW2), heat treatment on the tension yarn . Here the yarn is heated to about 18 (TC. The first test has been successful with a hot pin or with a heated roving machine (Galette) and with a hot plate (no contact). The result is unexpected, and the quality limit can be greatly improved in terms of the speed of transporting 201111572. The reason is that the above heat treatment has a fixed effect on the winding yarn and has a shrinking effect, thus contributing to B. The pre-heating treatment is more unexpected, and the thermal pretreatment also has a positive effect on the winding process. Here, a combination of the contraction and the opening action in the portion between the blowing position in the air blowing yarn passage and the first partial member of the tapered widening portion in the supersonic range should be such The cause of the result. Heating the yarn to reduce the brilliance is advantageous for forming a loop of yarn in the winding process P. To this end, the test can also be successfully completed using hot plates and hotspots as heat sources. In addition, one of the reasons for this effect is probably: the yarn is treated as a pre-treatment, and the negative cold effect caused by the expansion and contraction of the air in the winding nozzle can be avoided. Therefore, in the heated yarn, the winding effect can be improved. . At very high transport speeds, the 'heat-portion' remains in the yarn itself until the area where the loop is formed. Figure 9 shows the effect of the treatment agent, which may be hot air, or other hot gases, which are treated on the running yarn not far from each other or immediately before and after the treatment, for the verfahringing & the way, these procedures are separated from each other, and are tied to two yarn feeders, and = action, point combination. This means that 'the yarn is only kept at the front end and the end ^ (4) h gas treatment means and heat treatment means 0 this ==::::) or in the "(four) force (this one _ in the 10th figure a to d Gu + a Air, T .., with mechanical action and thermal action without partial separation. 23 201111572 This heat effect is in front of or behind the original contracting work in space. Even if a small value is used, the effect of the yarn heating is still The roll-up has a positive effect. The first diagrams a to d show the important possible use of the so-called φ human heating and driven coarse spinning machine (Galette) for heat treatment. The temperature values in the spinning machine are each displayed as a heating position. In this sense, a hot plate or a continuous steam chamber of the invention can also be used in all the drawings.
