DETAILED DESCRIPTION OF THE INVENTION The present invention involves dressing the end of the yarn to be separated.
singing) (pretrea sing)
It relates to a thread splicing device for splicing threads using compressed air.
The concept includes all thread-like threads that can be tied by a splicing device, such as spun threads and continuous filament threads, regardless of their use, such as woven threads or sewing threads.

[Prior Art] Its front side can be closed with indigo, which is open towards the sides, inside which the ends of the threads to be spliced are positioned and a jet of compressed air is applied for a preset time. A mixing chute 11 of suitable shape with an outlet for passing
In the technique of splicing woven or spun yarn using compressed air inside the chamber, the fibers of the two threads are mixed, intertwined, and wound together to form the yarn (↑). It is conventionally known to cover the ends of the yarn.The pretreatment process unravels, bifurcates, and separates the ends of the yarn. /II of the thread.

The purpose is to align the navy blue colors parallel to each other. This facilitates the complicated mixing σ11 and winding of the two threads to be spliced, and finally the spliced yarn changer that provides the best U1 mechanical strength and the optimum outer circle. It will be done.

For this reason, the yarn sewing device has a tri-cut britreating device for pretreating the ends of the yarn. In particular, Primil REET 1N consists of small duplexes located on both sides of the body with the mixing chamber.
FY is proposed.

The cut ends of the two threads to be twisted are drawn into the tube by the air blown onto the ends to be pre-trimmed inside the tube. For this purpose, each duplex is provided with at least one slanted nozzle through which the yarn blown into the duplex causes a pressure drop in the duplex and the cut end of said thread u1. The suction and further air flow created within the duplex unravel the threads, causing the molecules to escape from each other.

However, conventional devices for pretreating the ends of the threads to be spliced within the duplex where the yarn is supplied have several difficulties and drawbacks. That is, the problem arising from the space occupied by the tube and its total length, ensuring that the ends of the fibers of the thread are guided by the suction carried out through the slots provided inside the tube (SlOtS). In addition to problems such as the difficulty of processing, there are also problems related to measuring the velocity of the air flowing through the duplex, problems regarding pre-treatment time depending on the nature of the yarn, and unnecessarily excessive unraveling of the fibers. In order to prevent this, the problem is related to preventing the air from swirling inside the tube more than necessary, and it is also necessary to weave the ends of the yarn so that the jIcX fibers of the yarn are aligned parallel to each other. Problems include the need to control and predetermine the length of the thread sections.

In order to partially obviate the shortcomings and difficulties briefly mentioned above, the applicant has proposed the following three steps: lli: Tsuguga.

It was proposed to use a small tube for pretreating the cut ends of the yarn to be removed. Inside the small tube, the threads to be spliced are stretched in the axial direction of the duplex, and when air is injected into the duplex, they are free to move around and begin to vibrate.

According to that method, it is possible to considerably modify the effect of burritreating the yarn ends.

However, there are problems regarding the placement of the tube for the yarn splicing device, problems regarding its overall length, and problems with the construction of the tube. q of the cut thread is cut by suction carried out through the appropriate slot in the
The problem of the difficulty of introducing one part f1 and the uncertainty of its operation still remains unsolved.

[Object of the Invention] An object of the present invention is to provide a thread splicing device for splicing threads using compressed air. 7i effectively rR the ends of the threads, ensuring that the molecules 'll L,, the strands of the threads are aligned in parallel, and as a result, there are no dimensional problems and it is very safe. , and burry the end of the thread by simple means.
The purpose is to provide a yarn splicing device with many uses.

[Accomplishment of the Invention] According to the present invention, in order to achieve the above object, the threads to be spliced are cut by Vi compressed air (by means of an appropriate cutting member) inside a mixing chamber formed in the body. Dress the cut ends (Britley)!
[! )-rj The yarn splicing device is equipped with a dressing device (pre-leat device) for pulling the yarn, and the dressing device (pre-reed device) is injected with compressed air outward from both sides of the body. through a valve with an IJ (fQ fi+) of compressed air for exiting a jet of air; , the axis of the nozzle is oriented so as to substantially intersect a straight line connecting the side part 1 of the mixing chamber and the cutting member installed on both sides of the body in the cutting position. A yarn splicing device is provided.

A jet of compressed air passing through a nozzle installed on the side of the body of the mixing chamber (1. act on the ends of the thread protruding from each other, so that the end of the thread undergoes a flap action in the stream of compressed air, and the ends of the thread are unraveled, separated, and the weave of the thread is changed from one to the other. This will result in a whipping motion to the right which will have the effect of aligning parallel to .

Because of this, the ends of each thread for Britley 1~ are as follows:
An unrestrained flow of compressed air which acts on the end of the thread and brings about the desired Ni to the end of the thread, producing a strong flap action, rather than inside a small tube as is conventional. is carried out within.

According to the present invention, 1) 1q part of the thread to be dyed is pre-leaved. 1r'A 1. [Thread splicing limb [α
There is no need to use the troublesome tubes mentioned above on both sides of the body and r that hold the mixing chamber (
], but has the advantage, inter alia, that the end of the thread does not have to be placed inside the tube and into the air stream flowing inside the tube, and the compressed air flows out from the nozzle provided instead of the duplex. The jet of air will automatically catch the end of the thread and give it a whipping effect. The above-mentioned dimensional problems are thus solved and a considerably greater degree of safety is achieved.

For strongly twisted yarns where it is difficult to unravel the ends of the yarn and align the threads parallel to each other, the ends of the yarn should be unraveled and the ends of the yarn can be unraveled. : In order to enhance the action of the compressed air jet to the extent of aligning the tI in parallel and tendrils, a preferred embodiment of the present invention imparts a rotational action to the compressed air jet in order to unravel the ends of the yarn. Accordingly, an adjustment member is employed to adjust the jet flow of the closed air passing through the nozzles for the first and second parts.

When such a compressed air jet adjusting member is adopted, the compressed air jet passing through the nozzles for Britley 1 is adjusted in a direction opposite to the twisting direction of the yarn to be hit by the jet. Rotational motion can be given.

The vI adjustment means for the jet of compressed air is, for example, a means 6 for adjusting the vI of the jet of compressed air on the outside of the nozzle for the burry 1 from which the jet of compressed air flows out.
The nozzle can be formed by a semi-cylindrical wall portion that is fixed and allows a jet of compressed air passing through the nozzle to be jetted at a predetermined angle with respect to the nozzle. This causes a rotational movement in the air jet that rotates in a direction opposite to the twisting direction of the respective yarn. While the jet of compressed air is being fed to the brittle 1 by means of regulating the well, the thread glue part is partially surrounded by a semi-cylindrical wall part.

On the other hand, the t111 means of the jet of compressed air is located inside the nozzle for the pre-I-leat from which the jet of compressed air comes out. It is also possible to In that case, the above-mentioned adjustment means can be provided inside the nozzle, and can impart rotational motion to the jet and maintain the rotational motion along a predetermined length even after exiting the nozzle. What! ! According to the r+1 means of such a jet of compressed air, which can be opened by a single spiral element, and the resulting rotary action of the compressed air directed at the 03 section of the yarn, it unwinds the yarn and defibrates it. This makes it possible to align the fibers of the yarn in parallel, and even in the case of strongly twisted lζ yarn, the yarn can be easily untwisted and defibrated.
It is possible to align the fibers of the yarn in parallel.

Next, a method of using the yarn splicing device of the present invention constructed as described above will be explained.

2 to be spliced into the mixing chamber of the splicing device first
Position the book thread. Then, substantially at or preferably just before the cutting member cuts the tail of the thread, compressed air is supplied to the nozzle for pre-j-reet and exits from the nozzle for pre-j-reet. The cut end of the yarn is captured by the jet of compressed air (4"). On the other hand, the time to bridle the end of the yarn in the flow of the jet of compressed air depends on the nature of the yarn. They are sorted accordingly.

In that case, two or more nozzles with various cross sections, such as a combination of a main nozzle and a second nozzle so that they are oriented in opposite directions, may be used depending on the properties of the yarn to be processed. Can be used. Also, different types of nozzles may be provided in contact with both sides of the body having the mixing chamber. Furthermore, the output of the compressed air jet may be iME'D.

In the yarn grouping device of the present invention, the mixing chamber is formed inside the body by C145 processing, and the body is installed in the gap of the yarn piecing device so that it can be crossed.
It is preferable that it be sharpened. That gives each a frontage for compressed air! It is possible to attach a body for various mixing chambers, which has nozzles or nozzles arranged in various directions and shapes arranged at the A position, and the properties of the thread to be woven. It is possible to adapt the thread picker 1ii to different requirements based on.

Preferred embodiment 7J'I of the yarn splicing device of the present invention! i example 33
In this case, a nozzle for brining the ends of the yarn is inserted into an interchangeable body with a mixing chamber. This makes it easier to adapt the splicing device to the requirements of splicing threads of the scale type. Thus, each replaceable body has both a mixing chamber and a nozzle for the particular type of yarn.

Furthermore, when a body with a mixing chamber is provided with a nozzle for the mixing chamber, it has the advantage of being easy to arrange and requiring a small space for installation. This is because it is not necessary to individually arrange the briolite nozzle, which is installed in contact with the side of the body, with respect to each pipe line for supplying compressed air. In that case,
The nozzle for Brillite can also be developed as a side outlet of the a-cutting pipe (1), which is actually installed in the body with the mixing chamber. 11 to the valve for controlling the injection of compressed air via other pipes that are
I have sent one. Obviously, those routes must be diverted from other routes that are connected to other valves to inject compressed air into the mixing chamber.

The splicing device shown in the drawings may be provided with a milling chamber without a lid to close the front side of the mixing chamber or, if necessary, with a lid that opens the front side of the mixing chamber. Even if you can explain it, J.

From the above description it is clear how the pretries 1 to 1 of the ends of the threads to be hemped are carried out. That is, when two threads are placed in the mixing chamber, the ends of the threads located on the outside of the mixing chamber are moved through suitable nozzles provided in the side region of the body in which the mixing chamber is formed by v1 machining. The tail section is struck and torn off by the action of a jet of compressed air flowing out of the shaft. These jets of compressed air actually act on all the thread ends on the outside of the mixing chamber. That is, p of compressed air
71 Even if the jet does not seal the ends of the thread exactly, and if the jet and the thread intersect exactly, the ends of the thread must be positioned in a straight line and have a strong impact. The brapping and whipping action can be applied to the 6 parts of the thread, which can automatically catch the end of the thread in the same way, thereby untwisting the thread and unraveling the thread, resulting in Yarn factory ξ1r

A body (13) is shown with a second nozzle (52) having a smaller circular cross-section than that of 1). Phase 1 of some embodiments shown in Figures 11-14
(The only difference is the positional relationship between the main nozzle and the second nozzle.)

The shape (i13) and arrangement of the nozzle (91) for the pre-trimming nozzle or nozzle (91) mounted in the side region of the body (13) need not be identical on its opposite sides. In order to take into account the rise of the threads, it is preferable to select three different shapes of wires (or) on each side of the body.

What if a main nozzle and a second nozzle are provided? The axis of the rS2 nozzle may be slightly tilted relative to the axis of the main nozzle.

In Figures 9 to 14, each mixing stage A.
Although an identically shaped body (13) is shown with chamber (14) 1° to the right, it is clear that the mixing chamber could be formed in a variety of shapes depending on the properties of the yarns to be spliced. In that case, J: Eel mixing chamber d3 and Buri 1 are suitable for each type of yarn.
- A specific body (13) with a nozzle for Lee 1 is created. Since the body (13) can be easily replaced, the splicing device can quickly respond to the demands of the scale.

Further, the flow of compressed air supplied toward the pre-treat nozzle may be adjusted to one level. For such purposes, for example, a conduit (42) starting from the first valve (37)
A throttle valve that can adjust t1 from the outside may be inserted into the valve so that the flow rate of the compressed air flowing out to the pre-1 nozzle can be changed frequently.

In Figures 15 to 22, the cap (or block) (112), which is the structure of the splicing surface, is positioned between the two plays 1 to the right of the mixing chamber (114). It supports the body (113). The two-water threads to be spun are shown in (Δ) and (B).

First, the two threads are positioned on both sides of the body (113).
The two threads are inserted into the splicing device parallel to each other from the same side so as to be threaded, and the two threads are inserted into the above-mentioned cross section as shown in Fig. 15! A' (123) cross each other in the mixing chamber (114), are tightened by the elastic clamping member (124), and the positioning member (1

Inside the mixing chamber, nozzles are installed on both sides of the body (113) to brit treat the ends of the two yarns (Δ), J and (B), before being fed by fE compressed air.
There are tiers in the first part. The nozzle is supplied with compressed air for the outflow of the 71 stream of compressed air, and is connected to the side outlet of the mixing chamber and the light-spot member (
12G) It is oriented so that it intersects with the straight line connecting the two.

For that purpose, the body (113) to the right of the mixing chamber (114) is provided with horizontal dead bores (127), (128) at the bottom of the body (113). ) is mounted on a parallel axis perpendicular to the coarse axis of the mixing chamber (114) and is connected to a source of compressed air via a corresponding valve (not shown). Fittings to be connected (

The front side is open and forms a conduit arranged on an axis parallel to the longitudinal axis of the mixing chamber (114) (see FIGS. 17 and 18). It should be emphasized that the nozzles (129a) J and (130a) directed upward intersect obliquely with the semi-cylindrical walls (IEO) and (IGI), respectively. Therefore, the jet of compressed air that has passed through the nozzle (129a) and the onibi (1308) hits the semi-cylindrical wall (1(io)) and the open pipe (1(io)) formed by the semi-circular wall.
A vortex-like rotational movement is produced inside the opencl+annel in a direction determined by the centroid direction of the jet against the semi-cylindrical wall.

Its direction of rotation should be carried in the direction opposite to the direction of the twist of the yarn, which will hold the ends to be brimmed with a jet of compressed air. This is to untwist the original twist at the end of the yarn and to align the two fibers parallel to each other during the bridle-leat stage. Figure 18 shows exactly the 1st to 4th stages.

Semi-cylindrical walls (IGO) and (IGl) are formed, within which the ends of the threads are arranged as described above during the Buri I-leat stage and compressed. A conduit that has the effect of transmitting rotational motion to a jet of air is

sir+o) (pretreat processing
Dressing device (pre-treating device) for lng))
This invention relates to a yarn splicing device for splicing yarns using compressed air. In addition, in Suimei S, the term "thread" is a concept that includes all thread-like materials that can be spliced by a splicing device, such as spun yarn and continuous filament yarn, regardless of their use, such as weaving yarn, knitting yarn, sewing yarn, etc. F Prior Art] Its front side can be closed with a lid, which is open towards the side, inside which the end of the thread to be spliced is positioned and a jet of compressed air is applied for a preset time. In the technique of splicing threads using compressed air inside a suitably shaped mixing chamber with an outlet for passing
Mix and intertwine the two threads 1IiIIIfi,
It is well known in the art to pretreat the ends of yarns to be spliced prior to the process of winding and splicing yarns. The britreating process has the purpose of untwisting, defibrating, and separating the yarn and aligning the fibers of the yarn parallel to each other at the ends of the yarn. As a result, 1liIf of the two subsequent threads to be spliced
It is easier to mix, intertwine and wrap the t.
The end result is a spliced yarn with optimal mechanical strength as well as optimal appearance. For this purpose, the splicing device has a suitable britreating device for pretreating the ends of the yarn. In particular, burritreat devices have been proposed that consist of small tubes placed on either side of a body with a mixing chamber. The cut ends of the two threads to be spliced are guided inside the tube to burritreat therein by air blown against the ends. Therefore,
Each tube is provided with at least one angled nozzle through which air blown into the tube creates a pressure drop within the tube that sucks in the severed end of said thread and further The air flow created within the tube unravels the threads and causes them to separate from each other. However, conventional devices for pretreating the ends of yarns to be spliced inside an air-supplied tube have several difficulties and drawbacks. namely the problems arising from the space occupied by said tube and its entire length; the difficulty of reliably guiding the ends of the thread fibers by means of suction carried out through appropriate slots provided inside the tube; In addition to such issues, there are also issues related to measuring the velocity of air flowing through the tube, issues regarding the length of the burritreating process depending on the nature of the yarn, and furthermore issues related to the measurement of the velocity of the air flowing through the tube, and issues related to the length of the burrito treatment process depending on the nature of the yarn. Problems with preventing the air from swirling inside more than necessary;
Another problem is that it is necessary to control and predetermine the length of the portion of the yarn in which the ends of the yarn are to be unraveled and the fibers of the yarn are to be aligned parallel to each other. In order to partially obviate the shortcomings and difficulties briefly mentioned above, the applicant proposes to use a small tube for the pretreatment of the cut ends of the threads that are to be recently spliced. Ta. Inside the small tube, the threads to be spliced are stretched in the axial direction of the duplex, and the air is
- Once injected into the tube, it can move freely and begin to vibrate. According to that method, it is possible to considerably improve the effectiveness of the Britley 1 treatment of the yarn ends. However, there are problems with the arrangement of the tubes for the yarn splicing device and their fitting, as well as problems with the suction carried out through a suitable thrower installed in the duplex, which prevents the ends of the cut yarn from being removed. The problem of the difficulty of introducing the system and the uncertainty of its operation remains unresolved. [Object of the Invention] The object of the present invention is to effectively divide and separate the ends of the cut yarn into M fibers, and to align the 4 Hiffs of the yarn in parallel in a yarn splicing device for splicing yarns using compressed air. A yarn splicing device equipped with a pre-treating device for brining the ends of yarn in a very safe and simple manner without any dimensional problems. Our goal is to provide the following. [Structure of the Invention] According to the invention, in order to achieve the above object, the ends of the threads to be spliced by compressed air are cut by a suitable cutting member inside a mixing chamber formed in the body. A yarn piecing device equipped with a dressing device (pre-treating device) for dressing (pre-treating) the body, wherein the dressing device (pre-treating device N) supplies compressed air outward from both sides of the body. at least one nozzle in communication, via a valve, with a source of compressed air for exiting the jet, the nozzle being adjacent to opposite sides of the body having the mixing chamber; A splicing device is provided, the shaft of which is oriented to substantially intersect a straight line connecting a side outlet of a mixing chamber and cutting members provided on both sides of the body in a ready-to-cut position. The jet of compressed air passing through a nozzle located on the side of the body with the mixing chamber is directed at the end of the cut yarn, which has previously been introduced into the mixing chamber, i.e. the yarn protruding to the side of the mixing chamber. Acts on the end of the Thereby, the yarn ends undergo a flap action in the compressed air flow and are subjected to a whipping action which has the effect of unraveling and separating the yarn ends and aligning the yarn sections parallel to each other. become. Therefore, the burrito treatment of each yarn end is
This is not done inside a small tube as is conventional, but in an unrestrained flow of compressed air that acts on the ends of the yarn and produces a strong flap action that brings about the desired defibration of the ends of the yarn. It will be held in Therefore, the novel splicing device of the present invention for pretreating the ends of the weft threads to be spliced not only eliminates the need for such cumbersome tubes on both sides of the body having the mixing chamber, but also It has the advantage that the end of the thread does not have to be placed inside the tube and into the air stream flowing inside the tube.
A jet of compressed air flowing out from a nozzle provided in place of the tube automatically catches the end of the thread and creates a whipping effect. The above-mentioned dimensional problems are thus solved and a considerably greater degree of safety is achieved. Even in the case of strongly twisted yarns where it is difficult to unravel the ends of the yarn and align the fibers in parallel, we can unravel the ends of the yarn and align the fibers in parallel. In order to enhance the action of the jet of compressed air to the extent that An adjustment member is employed to adjust the jet of compressed air passing through the nozzle. When employing such a compressed air jet adjustment member, rotation in a direction opposite to the direction of twist of the yarn to be struck by the jet with respect to the compressed air jet passing through the pretreating nozzle is required. can be given action. The compressed air jet adjustment means is disposed, for example, outside a pretreat nozzle from which the compressed air jet flows out, and injects the compressed air jet passing through the nozzle at a predetermined angle with respect to the pretreat nozzle. It can be constructed by a semi-cylindrical wall section that can This results in a rotational movement in the air jet with a direction of rotation opposite to the direction of twist of the respective yarn. While being pretreated by the compressed air jet regulating means, the end of the thread is partially surrounded by a semi-cylindrical wall. On the other hand, the compressed air jet adjusting means can also be provided inside the buritreat nozzle from which the compressed air jet comes out. In that case, the adjustment means can be arranged inside the nozzle and can impart a rotational motion to the jet and maintain it along a predetermined length even after exiting the nozzle. It can be constructed by a helical element. According to such regulating means of the jet of compressed air and the resulting rotational action of the compressed air directed at the ends of the yarn, it is possible to untwist and unravel the yarn and to align the fibers of the yarn in parallel. This makes it possible to easily untwist and defibrate even strongly twisted yarns, and to align the fibers of the yarn in parallel. Next, a method of using the yarn splicing device of the present invention, which is constructed like a savior, will be explained. 2 to be spliced into the mixing chamber of the splicing device first
Position the book thread. then substantially at or preferably just before the cutting member cuts the thread tail;
Compressed air is supplied to the pretreating nozzle, and the jet of compressed air exiting from the pretreating nozzle ensures that the cut end of the thread is captured. On the other hand, the time for burritreating the end of the thread in the flow of the jet of compressed air is selected depending on the properties of the thread. In that case, and depending on the nature of the yarn to be pretreated, two or more nozzles with various cross sections may be used, such as a combination of a main nozzle and a second nozzle in different directions. I can do it. Also, different types of nozzles may be provided adjacent to both sides of the body containing the mixing chamber. Furthermore, the output of the compressed air jet may be adjusted. In the yarn splicing device of the present invention, the mixing chamber is preferably formed inside the body by machining, and the body is preferably attached to the cap of the yarn splicing device so as to be replaceable. This makes it possible to fit different mixing chamber bodies in which the openings for compressed air are provided with nozzles arranged in different positions or with different cross-sections and shapes, depending on the nature of the threads to be spliced. It is possible to adapt the splicing device to different requirements. In a preferred embodiment of the splicing device of the invention, an exchangeable body with a mixing chamber is provided with a nozzle for pretreating the ends of the yarn, thereby making it possible to process different types of yarn. It becomes easy to adapt the splicing device to the splicing requirements. Thus, each interchangeable body has both a mixing chamber and a britreating nozzle for the particular type of yarn. Furthermore, when a burriture nozzle is provided in a body having a mixing chamber, the advantages are that the construction is simple and the installation requires less space. That is, it is not necessary to individually arrange the burritreating nozzle, which is provided close to the side of the body having the mixing chamber, for each conduit for supplying compressed air. In that case, the pretreating nozzle can also be configured as a side outlet of a suitable conduit which is actually provided in the body with the mixing chamber. The conduit communicates with a valve for controlling the injection of compressed air via another conduit provided in the cap of the splicing device. Obviously, these lines must be separated from other lines for injecting compressed air into the mixing chamber, controlled by other valves.

A nozzle is provided adjacent to the side of the body (13) containing the mixing chamber (14) for pretreating the end of the mixing chamber (14). The nozzle has a nozzle oriented outwardly from the side of the body (13) and substantially intersecting a straight line connecting the side outlet of the mixing chamber and the respective cutting member (26) in the ready-to-cut position. Compressed air is supplied to eject a jet of air that is directed to do so. In particular, one embodiment shown in the drawings includes two lateral dead bores (13) at the bottom of the body (13) with the mixing chamber (14).
27) and (28) (see FIG. 1) are provided. The dead bores (21) and (28) are provided parallel to each other so as to be orthogonal to the longitudinal axis of the mixing chamber (14), and open at the back side of the body (13). From dead bore (21) and (28),

From the chamber (36) the conduit (35) extends further and finally reaches the chamber (39) of the second valve (40) with a movable shutter (41). The movable shutter (38) of the first valve (31) can be opened and closed, and when it is open, compressed air from the chamber (36) is transferred to the pipe (42) and the cap (12).
providing passages through bores (27) and (28) of the body (13) attached to the body (13). The axes of the bores (43) and (44) extend at right angles to the axis of the conduit (42). Furthermore, the movable shutter (41) of the second valve (40) is openable and closable, and when open provides a passage for the compressed air from the chamber (39) to pass through the conduit (45). The conduit (45) communicates with the bore (31) of the body (13) attached to the cap (12).

On the other hand, by opening the valve (4o), i.e. by lowering the movable shutter (41), the compressed air passes through the conduit (45) and the bore (31) with small diameter bores (32) and (33). It reaches the mixing chamber (14). The controls of the valves (31) and (4o), which are normally closed by respective resilient means (e.g. springs), are suitable for configuration of the splicing device so as to be synchronized with the substantial operating steps of the device of the invention. element (not shown). The operation of the yarn splicing device according to the present invention, which is equipped with a device for pretreating the ends of yarns to be spliced, will be explained below. The two threads to be spliced (A
) and (B) are positioned in position, the two threads are crossed over each other inside the mixing chamber (14), and the clamping member (20) and the resilient tightening member (24)
), the cutting member (2G) will operate to cut the two thread tails on the side of the plate (11) (see FIG. 6). The valve (37) cuts the tails of the two threads and at the same time
Or it is controlled to open just before that. That is, the movable shutter (38) of the valve (37) is lowered in order to pass compressed air towards the lateral pre-treating nozzles (29), (30) which have openings in the sides of the body (13). . As a result, the jets of compressed air flow out of the tenon (13) in opposite directions. 2 (7) threads (A
), (B) are struck and torn off by a jet of compressed air, so that over all parts of the two threads extending to the outer part of the mixing chamber (14), the cut ends of FIG. Then, a flap operation is performed to give a whipping effect as shown in FIG. The yarn is unraveled outside the mixing chamber by a flap action, and the fibers of the yarn become parallel to each other. The time of the pre-treat stage is preset by the nature of the yarn to allow for the desired result without excessive fiber loss. Once the end of the thread has been pretreated, the valve (37) is closed again so that the pretreatment nozzle (29)
, (30) will be interrupted. Subsequently, as shown in FIG. 3, the adjusting means (25) is adjusted so that the paths of the two threads (A) and (B)
) are controlled so that they approach each other largely from their initial positions, thereby drawing the ends of the reeled yarn into the mixing chamber (14). After the thread is placed in such position, the valve (40)
As a result, the pipe (45
), , bore (31) and small diameter bore (32) , (3
3), the splicing operation is carried out by suitably passing compressed air into the mixing chamber (14). Although the piecing device shown in the drawings is provided with a mixing chamber without a lid closing the front side, it may be provided with a lid closing the front side of the mixing chamber if necessary or desired. . From the above description it is clear how the britreating of the ends of the threads to be spliced is carried out. That is, when two threads are placed in a mixing chamber, the ends of the threads located on the outside of the mixing chamber are removed from suitable nozzles provided in the side region of the body in which the mixing chamber is formed by machining. Under the action of the outflowing jet of compressed air, the tail is struck and torn off. These jets of compressed air act on practically all of the ends of the thread outside the mixing chamber. That is, even if the jet of compressed air does not strike the ends of the thread exactly, or even if the jet and the thread do not intersect exactly, the jet will position those ends in a straight line and create a strong flap. The action and whipping action can be applied to the end of the thread and automatically catch the end of the thread in the same way, thereby untwisting the thread and defibrating the thread, so that the fibers of the thread are are made parallel. The axes of the side pretreating nozzles are oriented such that the jet of compressed air emerging from the nozzles impinges on the ends of the yarn between the outlet of the mixing chamber and the respective cutting member. There is. In the embodiment of the invention shown in FIGS. 6 and 7, the axes of the nozzles (29), (30) are arranged in the mixing chamber ( 14) parallel to the longitudinal axis. However, the jet of compressed air is
It is also possible to orient the nozzles (29), (30) in different directions, provided that the end of the thread is struck between the outlet of 4) and the cutting member. FIG. 8 shows the nozzle arrangement designated by (29a) and (30a). According to FIG. 8, the axes of the nozzles are connected to the respective cutting members (26) and the mixing chamber (14) ready for cutting, even though their axes are directed upwards.
You can see that it intersects with the straight line connecting it to the side exit. Depending on the properties of the yarn to be pretreated, a mixing chamber (1

In addition to the nozzle (51) with a circular cross section, the figure also shows a nozzle (51) with a circular cross section.
A body (13) is shown with a second nozzle (52) having a smaller circular cross-section than that of 1). The several embodiments shown in FIGS. 11-14 differ only in the mutual arrangement of the main nozzle and the second nozzle. The shape and/or arrangement of the pretreat nozzles or nozzles provided in the side regions of the body (13) need not be identical on opposite sides thereof. It is preferable to choose different shapes and/or arrangements on each side of the body (13) taking into account the twist of the threads. If a main nozzle and a second nozzle are provided, the axis of the second nozzle may be slightly inclined with respect to the axis of the main nozzle. In Figures 9 to 14, bodies (13) of the same shape with respective mixing chambers (14) are shown, but the mixing chambers can be formed in various shapes depending on the characteristics of the yarns to be spliced. It is clear that this is the case. In that case, a specific body (13) with a mixing chamber and a pretreating nozzle is created to suit the properties of each type of yarn. Because only the body (13) can be easily replaced,
The yarn splicing device can quickly respond to various requests. Furthermore, the flow of compressed air supplied toward the buritreat nozzle may be adjusted. For such purposes,
For example, an externally adjustable throttle valve may be inserted into the conduit (42) starting from the first valve (37) in order to vary the flow rate of the compressed air flowing out to the burritreat nozzle. In Figures 15 to 22, the cap (which is a component of the splicing device) is positioned between two plates.
or block) (112) supports a body (113) with a mixing chamber (114). The two yarns to be spliced are indicated by (A> and (B)). The two yarns are first passed through the splicing device parallel to each other from the same side so that they are positioned on both sides of the body (113). The two threads are then crossed within the mixing chamber (114) by the aforementioned cross member (123) as shown in FIG.

Inside the mixing chamber, nozzles are provided on both sides of the body (113) for pretreating the ends of the two yarns (A) and (B) before splicing them together with compressed air. The nozzle is supplied with compressed air for exiting the jet of compressed air and is oriented to substantially intersect a straight line connecting the side outlet of the mixing chamber and the cutting member (126) ready for cutting. ing. For that purpose, the body (113) with the mixing chamber (114) is provided with transverse dead bores (127), (128) at its bottom, the dead bores (127), (128) (1

Adjustment means are provided for adjusting the jet of compressed air passing by 0a). The adjustment means are arranged outside the nozzle. Specifically, in the case shown in FIGS. 15 to 18, the adjustment means is arranged in the respective nozzles (129a) and (129a) on both sides of the body (113).
It consists of semi-cylindrical walls (160) and (iei) placed at a certain distance from the outlet of the mixing chamber (130a); ) forming a conduit arranged on an axis parallel to the longitudinal axis (particularly the 17th

The jet of compressed air that has passed through 9a) and (130a) hits the semi-cylindrical wall (160) and forms an open pipe (open cl+a) formed by the semi-cylindrical wall (160).
A vortex-like rotational motion is generated inside the cylindrical wall in a direction determined by the direction of impact of the jet against the semi-cylindrical wall. Its direction of rotation should be chosen opposite to the direction of twisting of the yarn whose ends are to be burritreated with a jet of compressed air. This is because the britreating step untwists the yarn at its ends and unravels the yarn to align the fibers in parallel. Figure 16 and 1
Figure 8 shows just that burritreat stage. formed by semi-cylindrical walls (160) and (161) and within which the ends of said threads are arranged as described above during the pretreating stage and subjected to a rotational action to the jet of compressed air. The conduit, which has the effect of transmitting , pretreats in a freely open environment without confining the end of the thread. In another embodiment of the invention shown in FIGS. 19-22, the same parts as shown in FIGS. 15-18 are designated by the same reference numerals. From the respective bores (1271 and (128)), bores (129) and (130) extend laterally. The tubes (162) and (163), which do not directly constitute a nozzle for the purpose of the Small tube (162) and (
1G3) constitutes a nozzle for pre-treating and the axes of the tubes (162) and (163) connect the respective cutting members (12G) ready for cutting and the lateral outlet of the mixing chamber (114). It is oriented so as to substantially intersect the connecting straight line. The jet of compressed air passing through the nozzles (1 (32) and (163)) then impinges on the end of the thread in the immediate vicinity of the outlet area of the mixing chamber (114). The nozzle (162) and J:bi(1(
33) is provided with adjusting means for adjusting the jet flow of compressed air. The adjusting means consists of helical elements (164) and (165), as shown in FIGS.
2) and serves to generate rotational motion in the compressed air inside the nozzles (162) and (163). The compressed air jet becomes a rotating flow and passes through the nozzle (162
) and (163), thereby striking the ends of the yarn, thereby untwisting the yarn and unraveling the yarn, as clearly shown in FIGS. 20 and 22. Weave and arrange the threads so that they are parallel to each other. There is no causal relationship between whether the compressed air conditioning means is provided outside or inside the pre-treat nozzle and the specific shape and arrangement of the pre-treat nozzle. In other words, external adjustment means such as those described with reference to the embodiments of FIGS. 15 to 18 may be used, for example, in cases where the pretreatment nozzle cannot be fully realized in the body with the mixing chamber. However, the 19th to 22nd nozzles are machined into the body and consist of a simple conduit communicating with the body.
It is also possible to provide internal adjustment means of the type described with reference to the embodiment shown in the figures. It is also possible to suitably couple the external and internal adjustment means in order to obtain the desired coupling behavior. [Effects of the Invention] According to the splicing device of the present invention for burritreating the ends of yarns to be spliced, the conventional splicing device in which the ends of the yarns are attached to skillfully determined positions of the splicing device is improved. The main advantages are that no movements are required of the device and, in particular, that the ends of the spliced threads are less noticeable. Great security is thereby achieved when carrying out the pre-treat procedure. Furthermore, the piecing device of the invention has the advantage that it does not require additional components, which tend to cause dimensional problems in the design of the piecing device. In the yarn splicing device of the present invention, if an adjustment member for adjusting the air jet is adopted, the action of the air jet can cause the yarn to become i'i'
However, even in the case of yarns whose properties make it difficult to align the fibers in parallel, the effects of pretreating can be extremely poor on the ends of the yarns to be spliced. . 4.
