Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a creel for twisting and feeding an untwisted yarn material when it is fed to a predetermined device such as a loom or a warper.

[0002]

2. Description of the Related Art Conventionally, in order to manufacture various kinds of safety belts using twisted yarns as warp yarns and belt-like woven fabrics such as sling belts, a required number of twisted yarns are wound around a beam or weaved in advance. A method of winding on a bobbin, arranging the bobbin on a creel, and supplying the twisted yarn from the creel as warp yarn to a loom is adopted.

There are the following problems when weaving using twisted yarns as warp yarns. In other words, the twisting process is not carried out within the fabric manufacturer, and it is usual to ask an external twisting company to do so, but it is necessary to change the twist degree according to the texture required for each fabric depending on the application and yarn specifications. Nevertheless, it is inconvenient because the twisting degree cannot be changed after the twisting process, even if it is found to be defective. In addition, the twisted yarns of the same length are not always wound on each bobbin, and there are variations, and the twisted yarns are wasted. Furthermore, the length of the twisted yarn wound on the bobbin is at most one half, usually not more than one third, of the length of the raw yarn of the large package. It takes time and labor for replacement and thread knotting, and depending on the use of the product, the knotted part may be defective and must be discarded. As described above, in the case of weaving a woven fabric in which twisted yarn is used as warp yarn, there are many problems that are inconvenient as compared with the case where untwisted yarn is directly supplied from the creel to the loom.

On the other hand, when weaving untwisted yarn as warp yarns directly from the creel, there is almost no need to connect the raw yarns during the weaving because the raw yarns of the large and package are used as they are. Manufacturing efficiency is much better than the former case because there is no need for a rewinding process or warping process and there is no need to send the original yarn to an external twisting company to request the twisting process. However, the texture of the product is limited, and there are some problems in quality such as weakness and weakness against abrasion.Because it is untwisted during weaving, the filament does not bundle well and the yarn breaks. It is easily fluffed, and when it becomes terrible, there is the trouble of having to stop the loom and restore it to a normal state.

In order to solve the above-mentioned problems, the present inventor installed a twisting device having a structure similar to a flyer mechanism on each bobbin wound with untwisted yarn in Japanese Patent Application No. 57-029084. A creel was proposed in which the untwisted yarn is fed and twisted at the same time. According to the present invention, the purpose of twisting the untwisted yarn of the large package and supplying it to the loom can be achieved, but there is a problem that the equipment cost becomes large.

Therefore, in Japanese Patent Application No. 60-189847, a creel using a ring and a traveler as a twisting mechanism was proposed for the purpose of achieving the same effect with a relatively small capital investment cost, and the flyer mechanism was proposed. The structure is simpler and the cost is relatively cheaper than the similar structure. As a result, various problems in weaving using twisted yarn could be eliminated. However, even though the capital investment cost has become cheaper, there is a drawback that it requires a capital investment cost that is not overwhelmingly lower than the cost of twisting processing, and it is a fundamental solution to the problem. It didn't come.

In the above-mentioned two publicly known examples, the spindle driving means, which is the main part of the twisting mechanism, is explained by the combination of the shaft and the bevel gear in both of the embodiments. It was a cause of hindering the reduction of investment costs. Also, Japanese Patent Application No. Sho 60-189847
In the above-mentioned publication, there is disclosed an invention in which bidirectional twisted yarns of S twist and Z twist are supplied. However, a method of driving by a single motor and changing the rotation direction by changing the belt and a two-series driving device are used. stops the example, the rotation speed that is, no mention is about what changes the Yodo across multiple.

Further, each of the above-mentioned two publicly known examples only shows an example of using a raw yarn wound around a so-called straight paper tube (cylindrical paper tube), and a taper in which the thread is drawn out in only one direction. Nothing is touched on the case that uses paper tubes or aluminum pans. In the case where the predetermined device for supplying the twisted yarn is a loom, the above-mentioned conventional technique can be applied to the fabric having a simple specification configuration.

[0009] However, if the raw yarn material and the fineness are mixed,
In complex fabrics must be of a can cope Changes to become not rpm i.e. Yodo rotational direction only, further creel is provided with a usable twisting device in bobbin form other than straight paper tube It was requested.

[0010]

DISCLOSURE OF THE INVENTION The object of the present invention is to improve the drawbacks of the prior art and to easily change the twisting degree and the twisting direction as needed, and yet to wind the untwisted yarn to be wound. The purpose of the present invention is to provide a creel that expands the selection range of bobbin shapes, expands the applications, and significantly reduces the equipment cost.

[0011]

The present invention employs the following technical configuration to achieve the above object. That is, it has a spindle for supporting and fixing and rotating a bobbin wound with untwisted yarn, and a drive device for the spindle, so that the twisting process is performed in the process of pulling out the untwisted yarn from the bobbin and supplying it to a predetermined layer. A configured creel, wherein the spindle is a single spindle having at least two bearings in the central portion when viewed from the front of the creel body, and supporting and fixing the bobbins on the left and right sides thereof, respectively. A plurality of the spindles are arranged in parallel in the horizontal direction when viewed from the side of the creel, and a plurality of parallel groups of the spindles are provided in the vertical direction when viewed from the side of the creel. A creel equipped with a twisting device configured to rotate in a predetermined direction by a motor and drive transmission means and to have a variable number of rotations,
Further, the spindle drive device is a plurality of series including a motor and a drive transmission means, and each series is a creel configured so that the spindle can be changed in an arbitrary rotation direction and an arbitrary rotation speed.

The creel according to the present invention is to provide a creel equipped with a completely new twisting device by a combination of a bobbin attachment and a yarn adjust ring in addition to the above-mentioned new technique.

[0013]

In the creel according to the present invention, the new technique as described above is adopted, and unlike the conventional creel, the creel is provided with a completely new twisting device. As shown in FIG. 2, the spindle is
It is one spindle which has at least two bearings in the central portion as viewed from the front of the creel body and which supports and fixes the bobbins respectively on the left and right sides thereof.

That is, the rotation direction of one spindle naturally rotates in the same direction, but when viewed from the pull-out direction of the individual untwisted yarns on the left and right sides, the right side of FIG. 2 rotates clockwise. The left side of 2 is rotating counterclockwise. Therefore, on the right side of FIG. 2, when the untwisted yarn is unwound in the clockwise direction, the spindle is rotated to twist it into S twist, and on the left side of the figure, the untwisted yarn is unwound. It mounted in accordance with the counterclockwise direction is twisted in the Z twist by the rotation of the spindle.

When the rotation direction of the spindle is opposite to the example shown in the figure, naturally untwisted yarn is also set accordingly, so that the right side is Z twisted and the left side is S twisted. In the range in which the driving means are interlocked, the left and right are in opposite twist directions, and the number of rotations, that is, the twist degree is the same. Further, the spindle drive device is composed of a plurality of series of motors and drive transmission means, and each series is configured so that the spindle group can be varied in any direction and at any rotation speed. Even if the material and fineness of the yarn are different, it is possible to easily change the twist degree and the twist direction for each series according to each requirement.

On the other hand, in the creel according to the present invention,
As shown in Fig. 2, the bobbin wound with untwisted yarn supported and fixed to the spindle rotates in the direction in which the yarn is unwound, but the so-called ballooning size varies depending on the position where the yarn is pulled out. The length of the thread is also different. The yarn adjuster located at the exit of the yarn storage portion of the bobbin attachment keeps the yarn from coming out freely, so the tip of the yarn unwound excessively due to the fluctuation of the ballooning is not released to the yarn storage portion. It is temporarily stored so that it sickens.

The length of the thread that clings varies depending on the fluctuation of the ballooning, and this action adjusts the appearance of the thread due to the fluctuation of the ballooning. In addition, the yarn adjust ring exerts an almost constant tension on the yarn coming out of the yarn and twists the yarn before the exit, so that the twisting degree is kept constant.

By the combination of the yarn storage portion of the bobbin attachment and the yarn adjust ring, a stable unwinding and uniform twisting operation are performed, and the twisted yarn can be supplied to a predetermined device such as a loom or a warper. Of.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete example of the creel according to the present invention will be described below in detail with reference to the drawings. That is, FIG. 1 is a side view showing the overall configuration of a specific example of the creel according to the present invention, in which the required number of bobbins 3 around which the untwisted yarn 2 is wound (the side shown in FIG. 1). Then, 60 yarns and 60 yarns on the opposite side surface (total of 120 yarns) are arranged, and the untwisted yarns 2 are drawn out from the respective bobbins 3 and, at the same time, through the warp yarn aligning roller group 12 and a predetermined device 13 (For example, the loom in FIG. 1) is configured to supply the twisted yarn 4.

The predetermined device 13 may be a warper.
FIG. 2 is a specific example showing a twisting partial view, and the creel 1
Is equipped with a spindle 5 for supporting and fixing the bobbin 3 and rotating the bobbin 3, a motor 6 for rotating the spindle 5 and a drive transmission device 6a, and a tip portion of each bobbin supported and fixed on the spindle 5. A bobbin attachment 7 having a yarn storage portion 8 to which a yarn adjust ring 9 is fitted is fitted to each bobbin 3 as shown in FIGS. 6 and 7.
When the untwisted yarn 2 wound around the bobbin 3 is unwound from the bobbin 3 rotated by the spindle, the tip 10a of the ballooning 10 is the bobbin attachment 7
Enter the yarn storage section 8 of.

Although the length of the yarn storage portion varies depending on the size of the ballooning at the time of unwinding, the yarn storage portion goes around the outer periphery within a range not exceeding one round and then passes through the inside of the yarn adjust ring. Since the bobbin attachment 7 is rotating immediately after passing, a predetermined twist is applied to the yarn while reaching the yarn guide 11.

In the creel 1 according to the present invention, the untwisted yarn 2 is unwound while rotating the bobbin 3 to form the untwisted yarn 4 as the twisted yarn 4. The necessary twisting number of 4 is determined by the rotation number of the bobbin and the drawing speed of the untwisted yarn drawn from the bobbin. Therefore, in the present invention, as described above, the bobbin 3 can be rotated in any direction, and at the same time, the bobbin can be provided with any rotation speed. is necessary.

As the bobbin 3 used in the creel 1 according to the present invention, an example in which a cylindrical paper tube is used for the bobbin in FIG. 2 is shown. It may have any shape, material, and structure except for a pipe with a double collar such as a tapered pipe, a pan pipe, and the like. The yarn is drawn only from one direction of the bobbin. For example, in the case of a taper tube, the bobbin cannot be supported in the opposite direction, but in this case, the unwinding direction of the original yarn is specially divided into two directions. For example, the same twisting as in the above example can be performed.

The yarn wound around the bobbin may be a non-twisted yarn or a yarn supplied in advance as a sweet twisted yarn by the manufacturer (included in the category of untwisted yarn in the present invention) and is not particularly limited. is not. Further, the fineness of the untwisted yarn is not particularly limited, and may be appropriately selected according to the application in which the yarn is used.

If necessary, it is possible to obtain the same effect as the ply-twisted yarn by combining the original yarns. Further, in the present invention, a plurality of twisted yarn groups drawn from the creel
4 may all have the same number of twists or the same twist direction as necessary, and a part of the twisted yarns may have the same number of twists as other twisted yarns, or the twisted direction. May be different from each other, or may be arranged so that both the number of twists and the twisting direction are different from each other.

Further, in the present invention, as shown in FIG.
The spindle 5 is a single spindle which has at least two bearings in the central portion as viewed from the front of the creel body and which supports and fixes the bobbins on the left and right sides thereof.
That is, the rotation direction of one spindle naturally rotates in the same direction, but when viewed from the pulling direction of the left and right untwisted yarns, the right side of FIG. 2 rotates clockwise and the left side of FIG. Is rotating counterclockwise.

Therefore, the unwinding direction of the untwisted yarn is shown in FIG.
On the right side of the figure, it is attached in the clockwise direction and twisted into S twist by the rotation of the spindle. On the left side of the figure, it is attached in the counterclockwise direction with the unwinding direction of the untwisted yarn aligned and the Z twist by the rotation of the spindle Is twisted. In the range in which the driving means are interlocked, the left and right are in opposite twist directions, and the number of rotations, that is, the twist degree is the same.

Further referring to FIG. 2, a large number of spindles 5 (not shown here) are rotationally driven by the motor 6 and the drive transmission device 6a. The motor 6
The drive transmission means to the spindle 5 and the spindle 5 is not particularly limited, and any conventionally known method such as a chain drive method or a timing belt drive method may be adopted. Is particularly preferred for the reduction of

In FIG. 1, ten spindles are arranged in parallel in the horizontal direction as seen from the side of the creel, and six parallel groups of the spindles are provided in the vertical direction as seen from the side of the creel. Although an example in which each of the six drive motors is interlocked in the horizontal direction has been shown, the entire spindle is rotated in one predetermined direction by a single motor and drive means, and the number of rotations is made variable. It may be configured, or, of course, multiple motors,
The position of the motor may be above or below the creel.

However, the spindle drive device is composed of a plurality of series of motors and drive transmission means, and each of the series is configured to be able to change the spindle group in any rotation direction and any rotation speed. Is preferred. To be more specific with reference to FIG. 1, six motors 6-1 to 6-6 are arranged behind the creel 1, and a horizontal bobbin group is not shown. However, it is preferable that each drive system is configured so that the rotation direction and the rotation speed can be independently set.

With this configuration, it is possible to change the number of rotations for each series by setting the twist degree according to the fineness of the warp and the twist degree according to the purpose of use of the warp. If necessary, the untwisted yarn can be supplied as it is without rotating the series. The conversion of the rotation direction can be easily carried out by using a well-known suitable rotation direction switching means, or can also be carried out by a method in which a belt, a chain or the like is replaced.

In the specific example, the motor 6 is equipped with a transmission that reduces the number of revolutions to 1/10. For example, if the motor speed is 60 Hz and the motor speed is 1800 rpm, the output speed is 180 rpm.
Becomes In the specific example, the rotation speed of the motor 6 is controlled by changing the frequency through an inverter through a control panel. The frequency is changed in the range of 0 to 120 hertz, but in this case, theoretically, it is possible to set 0 to 360 rpm.

Further, although FIG. 1 illustrates that one motor system drives one group of spindles in the horizontal direction, a plurality of driving means are provided to drive a plurality of stages by one motor system. It is also possible. The distance between the spindles is determined by the bobbin that is normally used and the winding amount of the raw yarn wound around the bobbin. Various specific examples of weaving using the creel according to the present invention will be described below. For the sake of simplicity, an example of weaving two left and right woven fabrics using a needle narrow loom will be described. That is, 1) When all the motors 6-1 to 6-6 shown in FIG. 1 have the same rotation direction and the same number of rotations, the twisting degrees are all the same and the twisting directions are different between the left and right when viewed from the front of the creel. In this case, if the left and right threads of the creel are distributed to the left and right looms as they are, the right and left woven fabrics can have different twist directions. 2) If the Z twist and the S twist are distributed between the creel outlet and the warp aligning roller group 12, a woven fabric in which the S and Z twists are mixed in a predetermined width in each of the right and left two zones of the loom can be obtained. If the woven fabric is cedar twill weave using the same direction of twist yarn, the appearance of the twill differs depending on the twill direction, but with this method the twist direction can be changed for each twill, so the appearance of the twill is the same Fabric can be woven. A person skilled in the art can freely distribute the materials according to the specifications of the woven fabric. 3) When the rotation directions of the motors 6-1, 6-3, 6-5 are the same, and the rotation directions of the motors 6-2, 6-4, 6-6 are rotated in the opposite directions, the creel 1 The Z twist and the S twist are mixed on the left and right. The yarns on the left and right sides of the creel are directly drawn into the two left and right zones of the loom to be woven. When weaving a relatively strongly twisted yarn with a unidirectional twisted yarn, twisting occurs in the woven fabric, but the woven fabric woven in this way is Z twisted and S
Since the twists are mixed, it is balanced and does not twist. 4) There are cases where it is desired to use warp yarns having different thicknesses in one band fabric, or where the twist degree is partially changed even when yarns having the same thickness are used. In such a case, the motor 6-1
Each of 6-6 can be arbitrarily changed to set a twist degree required for each warp. Untwisted yarn can be supplied by stopping some motors if necessary. 5) If all the motors are stopped, it is possible to supply only untwisted yarn or untwisted yarn as it is, as in the conventional creel.

Although the above description has been made on the case where the creel according to the present invention is used in the loom, the present invention is not limited to the loom, and the present invention can be applied to the creel to be supplied to the warper. However, when it is used in a warper, the winding speed is faster than that of a loom, so that it is necessary to design a motor rotation output and a drive device corresponding to it. Next, a method for twisting an untwisted yarn using the bobbin attachment and the yarn adjuster will be described in detail.

The twisting method of the present invention is a novel twisting method that has not been heretofore known, and is characterized in that it is extremely simple and can be twisted at low cost as compared with any of various conventional twisting methods. For example, when weaving a narrow fabric with a needle loom,
At a speed of 2000 picks / minute, a weft threading number of 33 picks / inch is about 1.5 m / minute, and a weft threading number of 16.5 picks / inch is about 3.0 m / minute. Supplied. Since the speed is relatively low like this, it is 100
If the twist degree of t / m is given, the rotation speed of the bobbin is 1.5.
If the yarn speed is m / min, the rotation speed is 150 rpm, and if the yarn speed is 3.0 m / min, the rotation speed is 300 rpm. At such a low speed, the spindle rotation, the bobbin support mechanism, the bobbin attachment and the like have practically no problems even if the accuracy is relatively rough.

Basically, when the bobbin is rotated in the unwinding direction of the yarn and the yarn is pulled out, twisting is added to the yarn by itself. However, if the bobbin is simply rotated, the position of the yarn at the time of unwinding and the position at which the yarn starts to twist due to the influence of ballooning make the twisting degree unstable, and the unwinding itself is also unstable. The thread is cut due to the cause of the thread around the main body or the surrounding thread, which makes continuous operation of the loom impossible. Focusing on this point, the present invention absorbs the fluctuation of ballooning to stabilize the unwinding, stabilizes the twisting degree by making the position where the twisting starts to be constant, and further makes the tension of the yarn almost constant. It is intended.

That is, the point of the twisting system of the present invention consists of two parts, one of which is the bobbin attachment 7, which is a part to be fitted and fixed on the bobbin, and a yarn sending length which changes depending on the variation of ballooning. Is a component having a yarn storage portion 8 for storing the yarn and correcting the length of the yarn to be delivered. The other is a yarn adjust ring 9 which is attached to the tip portion of the yarn storage portion so that the untwisted yarn comes out freely. It has the function of holding down extra yarn in the yarn storage section if necessary so as to prevent it from going and giving a certain tension to the yarn by restraining the yarn, and the role of positioning to start twisting the yarn from this position. It is a part.

Further, the bobbin attachment 7 and the yarn adjust ring 9 will be specifically described. FIG. 5 (A) shows a bobbin attachment 1 according to the present invention.
It is a figure which shows the structure of a specific example, and is a side view of what is used for the aluminum pans of FIG. FIG. 5 (B) shows one specific example of the yarn adjust ring 9 used by being fitted to the bobbin attachment 7 of FIG. 5 (A) according to the present invention, which is a commercially available product based on JIS. It is a kind of so-called O-ring made of a synthetic rubber material and is preferably used.

The yarn adjust ring 9 has a predetermined elasticity and frictional force to hold the untwisted yarn 2 so as not to come out freely and to give a constant tension to the twisted yarn 4. So long as it is any.
Further, the yarn adjust ring 9 is not particularly limited as long as it is a material capable of exhibiting the above-mentioned function, but is, for example, one material selected from synthetic resin, synthetic rubber, natural rubber and the like. preferable. Further, not only a ring but a ring-shaped main body portion 200 made of synthetic resin as shown in FIG. 5 (C) and a large number of whiskers formed inside the main body portion 200 and inclined in one direction. It may be provided with a section.

The yarn storage portion 8 provided on the bobbin attachment 7 according to the present invention is provided on the outer peripheral surface of the bobbin attachment 7 and constitutes a groove body having an appropriate width and depth. It is a thing. The width and the depth of the yarn storage section 8 are not particularly limited, but the kind, the fineness, the number of constituent single fibers, the number of twists, and the draw of the material of the untwisted yarn wound around the bobbin 3 It is preferable to adopt an optimum dimension mainly in consideration of the shape of ballooning depending on the speed, the number of rotations of the bobbin, etc., and also considering the material, elasticity, frictional force, etc. of the yarn adjust ring. In any case, it must be designed so that the tip of the ballooning enters the yarn storage section regardless of where the untwisted yarn is pulled out. As one means for this, as shown in FIG. 4, it is desirable to provide a cover portion 80 for covering the bobbin main body up to the portion near the bobbin attachment 7 of the bobbin attachment 7.

In the creel of the present invention, when the untwisted yarn is unwound, it depends on various factors such as the yarn material, the fineness, the winding diameter of the yarn, the position of the yarn to be pulled out, and the number of revolutions of the bobbin. Although the size of the ballooning of the drawn-out yarn varies, the ballooning greatly expands when the yarn is drawn out from the front of the bobbin, and it hardly expands when the yarn is drawn out from the rear. This means that the length of the delivered yarn is long when the bulge is large, and relatively short when the bulge is small. On the other hand, since the yarn is pulled out at a constant speed, if it is left unattended, when the bulge is large, it is a problem that the yarn at the tip of the bobbin winds around the unwound portion. In order to correct this, the present inventor attaches an attachment to the tip of the bobbin and provides a portion around which the yarn is wound, that is, a portion called a yarn storage portion 8. However, this alone proved to be unstable, and as a result of attaching the yarn adjust ring 9 to the tip of the yarn storage section 8, it became possible to untwist and twist in a stable manner. Since the yarn to be pulled out is restrained by the yarn adjust ring 9, if the ballooning bulge is small, the yarn is pulled out with almost no winding around the yarn storage section 8, but if the bulging is large, it is wrapped around the yarn storage section 8. The length is corrected. As a result of the experimental observation, even when the yarn was wound, it did not exceed the outer circumference of the yarn storage portion 8. But,
If extra resistance is applied to the wound yarn, the fluctuation of the tension becomes large. To reduce this, the yarn storage section 8
The surface is effective to smooth as possible, also loose toward the yarn adjust ring 9 of the outlet, i.e. the tip
It is also effective to add a gentle taper. The bobbin attachment was manufactured using a relatively inexpensive synthetic resin molded product.

Although the twisting mechanism and structure have been described above, the creel of the present invention can also be used as a cover ring forming machine if the spindle is formed into a pipe shape and a member serving as a core is passed through this hollow portion. In FIG. 1, a warp yarn aligning roller group 12 is provided between the creel 1 and a predetermined device (loom) 13, but this device is used to adjust the tension when the drawn yarn has uneven tension. It works to absorb unevenness. Furthermore, if excessive tension is applied when twisting due to the material and fineness of the yarn, use a device that detects the tension during weaving and positively sends out the yarn to a part of the roller group. It is possible to

In the present application, the twisting mechanism and structure have been described by taking the example of using the combination of the bobbin attachment and the yarn adjusting, but the present invention is not limited to this example, and another one such as the ring-traveler system described in the prior art is used. Of course, such twisting mechanism and configuration may be used.

[0044]

Since the creel according to the present invention has the above-described structure, many effects as described below can be obtained. 1) As described above, according to the creel of the present invention, wasteful work due to the use of twisted yarn, for example, work on the twisting machine, rewinding work from the twisted bobbin, etc. can be omitted.・ Overall productivity such as cost is improved. 2) When a twisted yarn that has been pretwisted is used, the weight (length) of the yarn wound around the bobbin is smaller than that of the large package yarn supplied from the original yarn manufacturer, but in the present invention, the large package yarn is as it is. There are advantages that can be used. 3) Compared with the twisted yarn method such as the flyer method or the ring traveler method, the structure is overwhelmingly small, and with the exception of bobbin attachments, all ordinary ordinary commercial products are used. Can be manufactured.
As a result, the entire twisting mechanism can be manufactured at low cost, and the production cost of the product can be significantly reduced. 4) According to the creel of the present invention, in addition to the above effects,
When using S-twisted and Z-twisted yarns as warp yarns, there is no risk of erroneous placement of the yarns. Further, by using the S twisted yarn and the Z twisted yarn, it is possible to easily take measures against the twist of the product. 5) It is possible to easily give an appropriate twist to each yarn or warp of different materials and fineness. 6) When the multifilament yarn or the like is made to have a relatively strong twist, the yarn is twisted due to untwisting and the workability is deteriorated. Therefore, it is necessary to perform twist prevention processing. However, in the present invention, such twist prevention processing is not necessary. The sex is not lost. 7) In the present invention, since the yarn twisted to an arbitrary twist degree can be directly supplied to the weaving machine, it is possible to manufacture a product which is strong against abrasion with a good texture, and the twisted yarn twisted in advance is used. It is possible to manufacture a product of excellent quality with no yarn roughening as compared with the case. 8) In the present invention, a driving device is provided so that the number of rotations of the spindle can be changed. Therefore, it is possible to easily change the twist degree in the weaving process, which has not been possible in the past, and it is confirmed that the texture of the product is improved. You can do it while. 9) It is known that the twist strength of a so-called twisting machine is generally lower than the yarn strength of the original yarn, but the twisting thread of the present invention shows almost no decrease in the thread strength.

Therefore, the twisting technique of the present invention is extremely useful for products such as seat belts in which the strength is particularly required.
