It is composed of

In the case of Lennoji, the twisted warp, or the Leno warp, is always above the weft. The present invention considers an improvement in the weaving of a woven fabric using the Leno tissue technique.

To form the course of the Leno organization, one or more Leno slopes should be alternately distributed once per weft allowance to the other side of the branch, allowing Leno to twist around the geosergeant.

Although several devices have conventionally been designed to perform such distribution of leno slopes, most of them involve at least one of the following deficiencies.

(i) The fabrication of the device must be large and complex in order to produce a sufficiently firm edge.

(Ii) In order to perform a very sophisticated exercise, many movement elements are needed and thus many failures are caused, which shortens the life of the device.

(Iii) As the Leno slope contacts the restricted part of the thread guide element, a sharp depression is formed at the contact portion of the guide needle element, causing frequent cutting of the thread, thereby reducing the fluffs of the Leno slope. Occurs. To avoid these problems, frequent replacement of the guide needle element is required, which is disadvantageous in terms of savings in consumption, leading to an increase in labor costs.

(Iii) The device is unable to follow the high speed of the loom due to the precise movement of the relevant motion elements. This also makes it difficult to have multiple Leno organizations in a single edge magnetic device.

(Iii) Due to the sophistication of the structure, many of the motor elements are neither visible nor accessible from the outside of the device. This often delays the detection of abnormal behavior and makes maintenance difficult.

(Iii) Leno warp is liable to bend largely upon dispensing, thus causing undesirable damage to the leno warp and deterioration of the produced woven fabric.

It is a main object of the present invention to provide an edge weaving device which is simple in structure but capable of solid edge weaving.

Another object of the present invention is to provide an edge weaving device in which the movement is very simple, the life is long, and the number of movement elements is greatly reduced.

It is still another object of the present invention to provide an edge weaving device which can follow the high speed operation of the weaving machine and can easily increase the number of lenos in a single edge weaving device.

It is another object of the present invention to provide an edge weaving device that can be easily observed and accessed from the outside of the device and that the abnormal operation, early diagnosis and maintenance are easy.

It is still another object of the present invention to provide an edge weaving device which greatly improves the quality of the resulting woven fabric by not causing great warping of the leno warp during dispensing and thus greatly reducing damage to the leno warp.

According to the basic concept of the present invention, first, the distribution of the leno inclination is performed by the MAV system in which the distribution of the leno inclination is alternately performed for each weft.

Secondly, the associated motion elements require only simple vertical movement, while for the weaving, the opening swing of the inlet is black or the lever movement is used.

Third, the displacement of the leno slope is carried out by sliding contact of the slopes of the relevant elements.

Fourth, Leno slopes are minimal, but at the time of alternating distribution, they receive the necessary bending.

In the following description the elements of the edge weaving device of the invention are referred to as being fixed to the loom. Thus, the term "front" or "forward" refers to a position near the woven fabric, and the term "rear" or "rear" refers to a position near the inclined beam.

A first embodiment of the present invention is represented from FIG. 1 to FIG. A pair of nearly vertically extending anterior and posterior rods 2 and 4 are each aligned parallel to each other at appropriate intervals.

The front electrode 2 is provided with upper and lower horseshoe 4a and 4b enlarged at both ends.

By these ends 2a, 2b and 4a, 4b the rods 2 and 4 are respectively connected to an integral inlet for plain weave and move vertically as they move perpendicular to the integral inlet. Do it.

Guide needle holders 6a are inserted into the rods 2 and 4 under the upper end pieces 2a and 4a with no load. This holder 6a is hereinafter simply referred to as "upper holder". The distribution guide holder 6b is inserted into the rods 2 and 4 at no load on the lower knitting pieces 2b and 4b. This holder 6b is hereinafter referred to simply as "lower holder".

Both ends of the torsion spring 8 are connected to the rear of the upper holder 6a and the lower holder 6b, and the upper holder 6a is in contact with the upper horseshoe 2a and 4a by elastic pressure. The lower holder 6b is kept in contact with the lower end pieces 2b and 4b by the elastic pressure at all times.

The upper end of the fork guide needle 10 is fixed to the front surface of the upper holder 6a and extends downward.

As described in more detail below, the guide needle 10 has a hole.

The stopper 9 is fixed about the middle of the rear rod 4 and the guide plate holder 12 is inserted into the rods 2 and 4 with no load and the back extension of the plate holder is stopped. )

Guide plate holder 12 will hereinafter be referred to simply as an "intermediate holder". The guide plate 14 is fixed to the rear side of the intermediate holder 12 and extends laterally. The upper end of the distribution guide 16 is located at the lower end of the guide needle 10 in the state shown in the figure.

In the state shown in FIG. 1 the opening is closed and this state will hereinafter be referred to as the "neutral state". According to the basic concept of the present invention, when the device is in a neutral state, a predetermined gap D must be maintained between the top end face of the lower holder 6b and the bottom end face of the intermediate holder 12. The tension spring 17 is placed between the lower end of the guide plate 14 and the lower bent of the distribution guide 16. The positional relationship between the three guide needle elements in the neutral position, ie the guide needle 10, the dispensing guide 16 and the guide plate 14, is shown in detail in FIG. 3. end

In the illustrated embodiment, there are two pairs of upper and lower guide needle holes 14a and 14b in the guide plate 14, one pair for each stage of a leno. The guide needle holes 14a and 14b are positioned perpendicular to the lower guide needle hole 10b of the guide needle 10. As will be described in detail below, the guide needle 10 is made to guide the local tilt GY.

Therefore, the horizontal plane including the above common vertical line and extending in the oblique direction is hereinafter referred to as " local inclined plane GYP. &Quot; It is formed through a pair of upper and lower guide needle slots 16a for one stage of leno.

When viewed from the front of the device, the upper guide needle 16a slopes outwardly below the sloped surface GYP, starting at the interior position of the sloped surface GYP.

The lower guide needle 16b starts at an inner position of the local slope GYP and makes an outward inclination upward of the local slope GYP. In the illustrated state, the guide needle holes 14a and 14b of the guide plate 14 are located under the lower guide needle hole 10b of the guide needle 10 and the upper guide needle groove 16a of the distribution guide 16. The upper end of the guide plate 14 is located at the same level as the upper guide needle hole 14a, and the lower guide needle groove 16b of the distribution guide 16, the lower guide needle of the guide plate 14 It is located near the hole 14b.

The vertical distance between the ends of each guide needle groove 16a and 16b is equal to the vertical distance of gap D.

The operation of the above-described apparatus will be described in more detail with reference to FIGS. 4A-4G. From the inclined beam (not shown), the inclined slope GY is considered to run in the inclined direction via the upper and lower guide needle holes 10a and 10b of the guide needle 10. In addition, one leno tilt TIY runs in the same direction via the upper guide needle hole 14a of the guide plate 14 and the upper guide needle 16a of the distribution guide 16, while the other leno tilt TY2 is the guide plate 14 In the same direction via the lower guide needle hole 14b and the lower guide needle groove 16b of the distribution guide 16).

As already described above, the front and rear rods 2 and 4 are connected to the inlet for plain weave operation through the fragments 2a, 2b, 4a and 4b, respectively. Therefore, if one rod moves a certain distance up and down, the other rod moves the same distance up and down at the same time. In Figure 4 (a), the device is neutral and the rods 2 and 4 are also in neutral position. As the front rod 2 starts to move up in the neutral position, the rear rod 4 simultaneously starts to move down from the neutral position. As a result, the stopper 9 fixed to the rear rod 4 moves down and guide plate 14

According to the basic concept of the invention, the above-described relative motion between the two elements 14 and 16 is used to distribute the leno slopes TY1 and TY2 to both sides of the ground slope GY. For simplicity this relative motion is hereinafter referred to as "first relative motion". The state of the apparatus at the moment of the first relative movement is shown in Fig. 4B. The distance of the gap D between the middle and lower holders 12 and 6b is equal to D in the neutral state. Therefore, the intermediate holder 12 supporting the guide plate 14 moves down the same distance as D / 2, and the lower holder 6b supporting the distribution guide 16 is the same as D / 2.

The state shown in FIG. 4 (c) shows that the first relative motion has just been completed. The first relative motion ends when the holders 12 and 6b are in contact with each other. When the first relative motion is finished, the intermediate holder 12 is pushed up by the lower holder 6b and moves upward together. As a result, the guide plate 14 and the distribution guide 16 move upward while maintaining the relative vertical position shown in FIG. 4 (c). The upper holder 6a along the rear rod 4 and the downward motion is pushed down by the upper horseshoe 4a fixed to the upper horseshoe 4a fixed to the rear rods 4 and the upper arc

As the above-described vertical movement proceeds further, the apparatus reaches the state shown in FIG. 4 (d). In this state, the ground inclination GY controlled by the guide needle 10 is located in the lower sheet of the opening opening, while under the leno inclinations TY1 and TY2 controlled by the guide plate 14 and the distribution guide 16. do.

Thus the inserted weft W is located above the local slope GY and below the leno slopes TY1 and TY2.

An overview of the aforementioned vertical movement of the various members is shown in Table 1.

[Figure 1]

As the weft insertion is terminated, the device starts the next periodic motion and from the position indicated in figure 4 (d) the front rod 2 starts downward and the rear rod 4 starts moving upward, respectively.

The lower holder 6b is forced to the torsion spring 8 along the downward motion of the front rod 2 and moves downward with the lower horseshoe 2b. The distribution guide 16 fixed to the lower holder 6b also moves downward. Since the intermediate holder 12 is pulled toward the lower holder 6b by the tension spring 17, both the intermediate holder 12 and the guide plate 14 follow this downward motion.

Thus, in this stage of progression, the vertical position is maintained between the elements 14 and 16 shown in FIG. 4d.

It should be noted that this relative vertical position is similar to that in the state shown in FIG. 4C.

As the rear rod 4 moves up and down, the upper holder 6a, the guide needle 10, and the upper horseshoe 4a are forced to the torsion spring 8 to move up and down. The stopper 9 of the rear rod 4 also naturally moves up. As the opposite movement of the rods 2 and 4 proceeds further, the stopper 9 comes into contact with the bottom face of the intermediate holder 12 as shown in FIG. 4 (e). As the movement of the rods 2 and 4 proceeds further, the lower holder 6b and the dispensing guide 16 move down.

The stopper 9 of the rear rod 4 moving in the incense pushes up the intermediate holder 12 and the guide plate 14 starts the upward movement.

In other words, the relative vertical motion between the two elements 14 and 16 is started to distribute the leno slopes TY1 and TY2 to both sides of the ground slope GY. The ideal motion between two elements 14 and 16 is hereinafter referred to as the "second relative motion". During the second relative movement period, the guide plate 14 moves upward, while the distribution guide 16 moves downward to tighten the in-spring spring 17 sandwiched therebetween. Meanwhile, the guide needle 10 on the upper holder 6a continues the upward movement.

As described above, the first relative movement distance must be equal to D for the successful distribution of the Leno slopes TY1 and TY2 to the ground slope GY. It will now be clear that the second relative movement distance must be equal to D in order to achieve the same purpose. That is, when the guide plate 14 moves upward by a distance D / 2 from the position indicated in FIG. 4e and the distribution guide 16 moves downward by the distance D / 2, the second relative motion should be finished. Fig. 4f shows the state of the device when the second relative motion is completed, which is exactly the neutral state shown in Fig. 4a.

In this state, the opening is closed.

As the opposite movement of the two rods 2 and 4 proceeds further, the intermediate holder 12 is pushed upward by the stopper 9 and the guide plate 14 moves upward. The lower holder 6b is pushed up by the lower horseshoe 4b, and the distribution guide 16 moves upward by the same distance. That is, at this stage of the procedure, the two elements 14 and 16 move upward while maintaining the relative vertical position indicated in FIG. 4f, which is the same as that in FIG. 4a. Guide needle 10 proceeds downward movement.

As the above-described vertical movement is further progressed, the apparatus is in the state shown in FIG. 4G. In this state, the ground inclination GY controlled by the guide needle 10 is located in the lower seat of the deployment opening, while the leno inclinations TY1 and TY2 controlled by the guide plate 14 and the distribution guide 16 are deployed. Located on the top sheet of the. Thus, the inserted weft W is positioned above the top slope GY and below the leno slopes TY1 and TY2.

The vertical motion of each of the above elements is listed in Table 2.

[Table 2]

Edge weaving formation by the above-described apparatus of the present invention will now be described in detail with reference to FIGS. 5A-5E and 6A-6E. In the figure, the ground slope GY is omitted for simplicity and replaced by the slope slope GYP instead. In addition, the guide plate 14 and the distribution guide 16 were replaced by guide needle holes 14a and 14b and guide needle grooves 16a and 16b, respectively.

Although two stages of leno are formed simultaneously in the illustrated embodiment, the following description will be briefly limited to the left end of the leno.

As already explained, the distribution of the leno-tilts TY1 and TY2 to the ground slope GY is performed by the first and second relative motions of the guide plate 14 and the distribution guide 16. The specifications of the first and second relative motions of the two elements (14) and (16) are summarized in Table 3.

[Chart 3]

The first relative motion starts in the state shown in FIGS. 4a, 5a and 6a and ends in the state shown in 4a, 5a and 6a.

In the state shown in FIGS. 5A and 5A, one leno slope TY1 is located to the right of the sloped surface GYP, while the other leno slope TY2 is located to the left of the sloped surface GYP.

The ground slope GY takes the highest position and the other Leno slope TY2 takes the lowest position.

In accordance with the beginning of the first relative motion, the guide needle grooves 16a and 16b move upward and the guide needle holes 14a and 14b move downward. Thus, as shown in FIG. 5b, one leno bevel TY1 is pushed outward by the inner edge of the upper guide needle groove 16a to approach the bevel slope GYP from the inside, while the other leno bevel TY2 is bevel slope GYP from the outside. It is pushed inward by the outer edge of the lower guide needle 16b to approach.

This progress is shown in Figure 6b.

As the First Relative Movement continues, one Leno slope TY1 moves outward beyond the slope slope GYP, while the other Leno slope TY2 moves inward beyond the slope slope GYP.

Progressively At this stage, the original relative vertical position between the three slopes is invariant. Over time, two leno slopes TY1 and TY2 intersect under the local slope GY, and one leno slope TY1 crosses the other leno slope TY2 at the intersection.

The first relative motion, i.e., the first inclined twist operation, is completed in the state shown in Figs. 5c and 6c. At the time of weft insertion, the leno bevel TY1 is at the top and the bevel at GY is at the bottom. Thus, as indicated in FIG. 6d, the inserted weft W is positioned above the local tilt GY and below the leno tilts TY1 and TY2.

The second relative motion starts in the state shown in the 4e, 5c and 6d and ends in the state shown in the 4f, 5e and 6f. In the state shown in FIGS. 5C and 6D, one leno slope TY1 is located to the left of the steep slope GYP, while the other leno slope TY2 is to the right of the steep slope GYP. The ground slope GY is at the top and the other Leno slope TY2 is at the bottom.

As the second relative motion starts, the guide needle grooves 16a and 16b move down and the guide needle holes 14a and 14b move up. Thus, as shown in FIG. 5 (d), one leno tilt TY1 is pushed inward by the outer side of the upper guide needle groove 16a so as to approach the ground slope GYP from the outside, while the other leno slope TY2 is tilted from the inside to the slope surface. It is pushed outward by the inner side of the lower guide needle groove 16b to approach the GYP.

As the second relative movement progresses further, one Leno slope TY1 moves inward past the steep slope GYP and the other Leno slope TY2 moves out past the steep slope GYP.

In this phase of progress, the original relative vertical position between the three slopes is unchanged. As a result, the two Leno slopes TY1 and TY2 cross below the local slope GY, and one Leno slope TY1 crosses over the other Leno slope TY2 at the intersection.

The second relative motion, i.e., the second tilt motion, is completed in the state shown in Figs. 5e and 9f. At the time of weft insertion, the Leno slope TY1 reaches the highest value, and the ground slope GY takes the lowest position. Thus, as shown in Figure 6g, the inserted weft W is located above the local tilt GY and below the leno tilt TY1 and TY2. By repeating the above-described inclined twist operation, the leno inclination is alternately positioned on different sides of the local inclination, and one weft insertion is performed for each inclination operation to form the leno edge weave shown in FIG.

In this formation of the leno weaving, the leno slopes TY1 and TY2 always intersect under the ground slope GY, at the intersection the leno slope TY1 always passes above the other leno slopes TY2, and the leno slopes TY1 and TY2 are always above the top and bottom W, Also, the steep slope GY is always located under the weft W.

A second embodiment according to the invention is shown in FIG. 8 and in this example a pair of firsts for the distribution of leno slopes TY1 and TY2 instead of the combination of the guide plate 14 and the distribution guide 16 of the first embodiment. And second distribution guides 24 and 26 are used. The first distribution guide 24 is fixed by the intermediate holder 12 and the second distribution guide 26 is fixed by the lower holder 6b.

The other structure and operation of the apparatus are generally similar to that of the first embodiment. Thus, the two distribution guides 24 and 26 perform the first and second relative motions in the above-described temporal order, and the movement distances are both equal to the vertical distance of the gap D.

Two pairs of upper and lower guide needle grooves 24a to 24d are formed in the first distribution guide 24. When viewed from the front of the device, the upper guide needle grooves 24a and 24c are inclined downward, inward of each steep slope GYP, starting at a position outside of each steep slope.

The lower guide needle grooves 24b and 24d are inclined upwards, starting at the position outside of each steep slope GYP, and inward of each steep slope GYP. The vertical distance between both ends of the guide needle grooves 24a to 24d is equal to the relative movement distance D, that is, the vertical distance of the gap D. Two pairs of upper and lower guide needle grooves 26a and 26d are also formed in the second distribution guide 26.

When viewed from the front, the upper guide needle grooves 26a and 26c start at a position outside of each steep slope GYP and make a slope upwards into each steep slope GYP.

The lower guide needle grooves 26b and 26d start at an outer position of each steep slope GYP and incline downwards into each steep slope GYP. The vertical distance between both ends of the guide needle grooves 26a to 26d is equal to the relative movement distance D, that is, the vertical distance of the gap D. The operation of the above-described apparatus will be described in more detail with reference to FIGS. 9 (a) and 9 (c). Although two stages of leno are formed simultaneously in the illustrated embodiment, the following description will be briefly limited to only the left stage of leno.

The state shown in FIG. 9A corresponds to the state at the beginning of the first relative movement or at the end of the second relative movement. When viewed in the inclined direction in this state, the upper and lower guide needle grooves 24a and 24b of the first distribution guide 24 are upper and lower guide needle grooves 24a of the second distribution guide 26. And (26b) the arrangement is designed to be in line with the top. One leno bevel TY1 is controlled by the occlusal contact of the upper guide needle grooves 24a and 26a, and is located inside the steep slope GYP. The other leno tilt TY2 is controlled by the occlusal contact of the lower guide needle grooves 24b and 26b.

As the first distribution guide 24 moves downward and the second distribution guide 26 moves upward, the occlusal points of the upper guide needle grooves 24a and 26a move outward, and one leno tilt TY1 moves from the inside. The slope is approaching the GYP. At the same time, the occlusal points of the lower guide needle grooves 24b and 26b move inward, causing another leno tilt TY2 to approach the local slope GYP from the outside. This procedure is shown in Figure 9b.

The first relative motion between the two distribution guides 24 and 26 continues until the state shown in Fig. 9C is reached. In this state, one leno slope TY1 is located outside of the steep slope GYP, and the other leno slope TY2 is located inside of the steep slope GYP. That is, the first distribution of the leno slopes TY1 and TY2 to the local slope GY is completed.

In the state shown in FIG. 9C, the upper ends of the upper and lower guide needle grooves 24a and 24b of the first distribution guide 24 are upper, lower guide needle grooves 26a and (2) of the second distribution guide 26. The device is manufactured to be in line with the bottom of 26b).

The state shown in Fig. 9C corresponds to the state when the second relative motion is started.

As the first dispensing guide 24 moves up and the second dispensing guide 26 moves down, the contacts of the upper guide needle grooves 24a and 26a move inward so that from the outside of one leno tilt TY1 The slope is approaching GYP. On the other hand, the occlusal points of the lower guide needle grooves 24b and 26b move outwards, and the other leno slope TY2 approaches the local slope GYP from the inside.

This progress is shown in Figure 9b.

The two distribution guides 24 and 26 proceed relative motion until they reach the state shown in Fig. 9 (a). In this state, one leno slope TY1 is located on the inside of the ground slope GYP, and the other leno slope TY2 is located outside of the ground slope GYP.

In other words, the second distribution of the leno slopes TY1 and TY2 to the local slope GY is completed.

By repeating the above procedure, the pairs of inclinations TY1 and TY2 are alternately arranged on different sides of the local inclination GY to form the leno edge weave shown in FIG.

A third embodiment according to the present invention is shown in FIG.

The apparatus has a different driving direction of the guide needle grooves 34a to 34d and 36a to 36d than that of the above-described embodiment. Other structures or operations are generally similar to those of the second embodiment. Two pairs of upper and lower guide needle grooves 34a to 34d are formed in the first distribution guide 34. When viewed in the inclined direction, the upper guide needle grooves 34a and 34c are inclined upwards, starting from the outside of the respective slopes GYP, and inward of the respective slopes GYP. The lower guide needles 34b and 34d start at an outside position of each steep slope GYP and incline downward into each steep slope GYP.

The vertical distance between both ends of each of the guide needles 34a to 34d is equal to the relative movement distance D of the elements 34 and 36.

This is equivalent to the vertical distance of the gap between two holders 12 and 6b. The operation of the above-described apparatus will be described in detail with reference to FIGS. 11A-11C. Although two levels of leno are formed at the same time in the illustrated embodiment, the following description will be limited only to the left-side leno.

The state shown in FIG. 11A corresponds to the state when the first relative motion or the second relative motion is finished.

In this state, when viewed from the inclined direction, the upper and lower guide needle grooves 34a and 34b of the first distribution guide 34 are upper and lower guide needle grooves 36a of the second distribution guide 36. And the arrangement is designed to be in line with the upper end of 36b. One leno bevel TY1 is controlled by the occlusal points of the upper guide needle grooves 34a and 36a and is located outside the local slope GYP. The other leno tilt TY2 is controlled by the occlusal points of the lower guide needle grooves 34b and 36b and is located inside the steep slope GYP.

As the first distribution guide 34 moves downward and the second distribution guide 36 moves upward, the upper guide needle grooves 34a and 36a move inward so that one leno slope TY1 is from the outside to the slope GYP. Approach At the same time, the lower guide needle grooves 34b and 36b move outwards to allow another Leno slope TY2 to approach the local slope GYP from the inside.

This procedure is shown in Figure 11b.

The first relative motion between the two distribution guides 34 and 36 proceeds until the state indicated in Fig. 11C is reached.

In this state, one leno slope TY1 is located inside the sloped surface GYP and the other leno slope TY2 is located outside the ground slope GYP. That is, the first distribution of the Leno slopes TY1 and TY2 to the local slope GY is completed. The upper and lower guide needle grooves 34a and 34b of the first distribution guide 34 are aligned with the lower ends of the upper and lower guide needle grooves 36a and 36b of the second distribution guide 36. The device is fabricated.

The state indicated in FIG. 11C corresponds to the state when the second relative motion between the two guides 34 and 36 starts.

As the first distribution guide 34 moves upward and the second distribution guide 36 moves downward, the occlusal points of the upper guide needle grooves 34a and 36a move outward, so that one leno tilt TY1 is inside Approaching slope at GYP. This procedure is shown in Fig. 11B.

The two distribution guides 34 and 36 continue their relative motion until they reach the state shown in Fig. 11A. In this state, one leno slope TY1 is located outside the local slope GYP, and the other leno slope TY2 is located inside the local slope GYP.

In other words, the second distribution of the Leno slopes TY1 and TY2 to the local slope GY is completed.

By repetition of the above procedure, the pair of leno tilts TY1 and TY2 are alternately placed on different sides of the subtilt GY to form the leno edge weave shown in FIG.

In the case of the second and third embodiments, the leno tilt is controlled by the bite point of the pair of inclined guide needle grooves which cooperate during the lateral motion. This control ensures largely stable distribution of the leno slope to the local slope by sufficiently suppressing undesired whipping of the leno slope.

In the first, second and third embodiments of the present invention, one stage of leno consists of three sets of twisted warp yarns, ie a pair of leno warps arranged alternately on different sides of the local and local warp yarns. However, the present invention also applies to a case where a single leno consists of a pair of inclinations, i.e., one leno inclination alternately arranged on different sides of the inclination and the inclination.

The fourth embodiment of the present invention in the above-described form is shown in FIGS. 12 to 14, in which the same reference numerals are used for elements that are substantially similar in structure or elements to those used in the above embodiments. . The apparatus of the present embodiment is adapted to form a two-stage leno while being composed of a local tilt GY and a leno tilt TY, respectively.

One catcher holder 42 (hereinafter referred to as the "middle holder") is fixed about the middle of the rear rod 4 and inserted into the no load over the front rod 2. This intermediate holder 42 is provided with one catcher plate shown in FIG. 14 in front.

The catcher plate 44 has a pointed top head 44a and a pair of guide needle notches 44b arranged on both bottom faces of the center head 44a, and one notch 44b has one end. It's for Leno.

Guide plate holder 6b (hereinafter referred to as "lower holder") is provided with a guide plate 46 extending upwardly on the rear surface.

The guide plate 46 has a guide needle hole 46a for maintaining a pair of side gaps formed at an upper end thereof.

The relative positions between (10), (4) and (46) of the engaging elements in the neutral state are shown in FIG. In this state, each of the lower guide needle holes 10b of the guide needle 10 is slightly above the center of the catcher plate 44 on the outside of the corresponding guide needle hole 46a of the guide plate 46, and the catcher plate. It is located inside the corresponding guide needle notch 44b of 44. The vertical position of each guide needle hole 46a of the guide plate 46 is almost similar to that of the corresponding guide needle notch 44b of the catcher plate 44.

The operation of the above-described apparatus is as follows.

Rods 2 and 4 are operatively connected to the coupling device for plain weave. Therefore, if the front bar (2) moves a certain distance upward, the rear bar (4) moves a similar distance downward. Since the catcher plate 14 is fixed to the rear rod 4 by the intermediate holder 42, the catcher plate 14 follows the above-described downward motion of the rear rod 4. The upper holder 6a is supported by the upper horseshoe 4a fixed to the rear rod 4, and the guide needle 10 fixed therein also follows this downward motion. In accordance with the upward movement of the fore (2), the lower holder (6b) is supported up by a single piece fixed to the fore (2) and the guide plate 46 is moved the same distance upward.

As the front rod 2 moves down, the rear rod 4 thus moves upward. The catcher plate 44 fixed to the rear rod 4 through the middle holder 42 along the upward motion of the rear rod 4 moves upwards the same distance. As the yarn lower holder 6b is lifted up by the defective horseshoe 4b fixed to the rear rod 4, the guide plate 46 supported by the lower holder 6b moves upward the same distance. .

Simultaneously with this procedure, the upper holder 6a is pushed down by the upper horseshoe 2a fixed to the electric rod 2, so that the guide needle 10 supported by the upper holder 6a has the same distance. To move downward.

The procedure described above is summarized in Table 4.

[Table 4]

Summarizing the kinetic relationship between the coupling elements 10, 14 and 16 from the diagram, when the forehead 2 moves up or down a certain distance, (a) the guide needle 10 always maintains the same distance. It moves downward, (b) the catcher plate 44 moves the same distance downward or upward, and (c) the guide plate 46 always moves the same distance upward.

The formation of the leno edge weave by the device of the above-described structure is described in more detail below. Each leno bevel TY is controlled by the guide needle hole 46a and the catcher plate 44 of the guide plate 46, and each local inclination GY is the guide needle 10 of the guide needle hole 46a of the guide plate 46. And the catcher plate 44, and each local inclination GY is controlled by the guide needle hole 10b of the guide needle 10. As shown in FIG. Although two stages of leno are formed at the same time by the apparatus of this embodiment, the following description will be limited to only the leno of the left stage.

The neutral state of the device and the slope is shown in Figures 15a, 16a and 17a where the opening is closed. The local inclination GY passes through the guide needle hole 10b of the guide needle 10 and the leno inclination TY passes through the guide needle hole 10b of the catcher plate 44 and the guide needle notch of the leno inclination TY catcher plate 44. Under control of 44b.

The guide needle notch 44b is located outside the guide needle hole 10b of the guide needle 10. Thus, the leno tilt TY is located outside of the associated ground slope GY as shown in FIG. 17A. In the first opening movement, as shown in FIG. 15B, the front rod 2 moves up and the rear rod 4 moves down. Following this movement, the guide needle 10 moves down, the catcher plate 44 moves down, and the guide plate 46 moves up. As a result of such relative movement, as shown in FIG. 16B, the Leno slope TY is the guide needle of the catcher plate 44.

In the second opening movement, the forefoot 2 moves down and the forewheel 4 moves up. As clearly shown in Table 4 and also indicated in FIG. 15C, the guide needle 10 moves down, the catcher plate 44 moves up, and the guide plate 46 moves up. Along the upward movement of the catcher plate 44, the leno tilt TY held by the guide plate 46 comes into contact with the inclined shoulder of the center head 44a of the catcher plate 44, as shown in FIG. 16C. It is gradually pushed outward.

After exiting the outer slope GY caught by the guide needle 10, the Leno slope TY is dropped and placed again under the control of the guide needle notch 44 of the catcher plate 44. However, the device should be designed so that the Leno bevel TY is placed above the branch GY. Thus, the leno slope TY moves from the inside of the slope to the outer side of the slope as it passes through the slope of the slope. The inserted weft is located above the local tilt GY and below the leno tilt TY, as shown in FIG. 17C.

By periodic repetition of the above procedure, the device of the present invention forms an edge weave with two levels of leno.

A fifth embodiment according to the present invention is shown in 18th, 19a-19c, and 20 degrees. In this embodiment, a guide assembly composed of front, middle, and rear guide plates 52, 54, and 56 instead of the combination of the guide plate 46 and the catcher plate 44 used in the fourth embodiment. 50 is used. The three guide plates 52, 54 and 56 are arranged with a spaced side by side in parallel at substantially the same vertical position, as described in more detail below.

In the city shown in FIG. 18, the spacing between adjacent guide plates is much larger than it is to make the structure easier to understand. As shown in FIG. 19A, the front guide plate 52 has a pointed guide portion 52b which is pointed upwardly, which is fixed to the front rod 2 through the support portion 52a and determined by two inclined shoulders 52c. . When viewed in the inclined direction, each shoulder 52c extends downward from the inside of the sloped surface GYP, starting from the inside of the sloped surface GYP. As shown in FIG. 18B, the intermediate guide plate 54 is lowered through the support portion 54a.

The guide portion 54b has a pair of triangular holes 54c. The upper vertex of each hole 54c is located on the local slope GYP and the outer vertex is located outside the local slope GYP.

As shown in FIG. 19C, the rear guide plate 56 is fixed to the rear rod 4 by the support 56a and has a guide needle notch 56b determined by a pair of inclined shoulders 56c. .

When viewed from the inclined direction, each shoulder 56c extends downward, starting from the outside of the local slope GYP, and inward of the local slope GYP. The positional relationship of the engaging elements 52, 54 and 56 when the device is in the neutral state is shown in FIG. 20, in which the opening is closed. In this state, the guide plates 52, 54, and 56 are located under the hole 10b of the guide needle 10, and their upper surfaces are substantially at the same height.

In this state and also in further oblique view, the outer edge of each hole 54c of the intermediate guide plate 54 is located outside the associated inclined shoulder 52 of the front guide plate 52.

The operation of the apparatus having the above-described structure is as follows.

As the above-described embodiments likewise move the front rod 2 up a certain distance, the rear rod 4 downwards the same distance. The rear guide plate 56 fixed there along the downward motion of the rear rod 4 also moves the same distance down.

As the upper holder 6a is pushed down by the upper horseshoe 4a fixed to the rear rod 4, the guide needle 10 fixed thereto moves downward the same distance.

As the electric pole 2 moves upward, the lower horseshoe 2b fixed thereto pushes the lower holder 6b and moves both the middle and front guide plates 54 and 52 upward by the same distance. . As the front bar 2 moves up a certain distance, the rear bar 4 moves down the same distance. The rear guide plate 56 moves up the same distance along the upward movement of the rear rod 4.

As the lower holder 6b is lifted up by the lower horseshoe 4b which can move together with the rear rod 4, the intermediate guide plate 54 fixed thereto moves upward the same distance.

In accordance with the downward movement of the front rod (2), it is pushed down by the upper holder (6a), the upper horseshoe (2a) that can move together with the front rod (2), the guide needle (10) and the front guide plate (52) ) Both move the same distance downward. The above process is summarized in Table 5.

[Table 5]

As is clear from this diagram, the relative motions of the three guide plates 52, 54 and 56 that combine are as follows.

As the front wheel 2 moves up or down a certain distance, (a) the guide needle 10 always moves down the same distance, and (b) the front guide plate 52 moves up or down the same distance. (C) the middle guide plate 54 always moves the same distance upward, and (d) the rear guide plate 56 moves the same distance downward or upward.

Reno edge weave formation by the apparatus described above will be described in more detail with reference to FIGS. 20, 21 (a) and 21 (b).

Each leno tilt TY passes through the intermediate guide plate 54, and the local tilt GY is controlled by the guide needle 10.

In the neutral state of the apparatus shown in FIG. 20, the inclined opening is closed. The leno tilt TY is located near the upper vertex of the hole 54c of the intermediate guide plate 54 and is controlled by it. In this state, the Leno slope TY is generally located at the ground slope GYP. In the state shown in Fig. 21A, the front rod 2 moves upward, and the rear rod 4 moves downward during the movement. As evident in Table 5, the guide needle 10 thus moves downward, the front and middle guide plates 52 and 54 move both, and the rear guide plate 56 moves downward. Such

During the next opening movement in the state shown in Fig. 21B, the front rod 2 moves downward and the rear rod 4 moves upward.

As a result of this relative movement, the Leno slope TY remains bitten only in the middle and rear guide plates 54 and 56, and the front guide plate 52 exits from this coupling. Therefore, the leno tilt TY is pushed inward by the inclined shoulder 56c of the rear guide plate 56 and moves inward of the hole 54c of the intermediate guide plate 54. When the opening movement is completed, the leno tilt TY is moved to the outer end of the inclined shoulder 56c of the rear guide plate 56, that is, the position of the inner side of the ground tilt GY controlled by the guide needle 10.

By repetition of the above procedure, the Leno slopes TY are alternately placed on one side of the designator GY to form an edge weave consisting of two stages of leno.

In the case of the fifth embodiment, during the lateral motion, each leno slope TY corresponds to the inclination of the inclined shoulder 52c of the front guide plate 52 and the hole 54c of the intermediate guide plate 54 (see FIG. 21A). The same side of the inclined shoulder 56c of the rear guide plate 56 and the hole 54c of the intermediate guide plate 54 (see FIG. 21B), controlled by a narrow and inclined groove defined by the outer side It is controlled by a similar narrow and inclined groove defined by.

Thus, unwanted whipping of the inclined TY during dispensing can be effectively avoided. In FIG. 16C, in FIG. 21A and 21B, the Leno slope TY moves in the narrow and inclined groove described above, since the same is also located in the upper sheet of the deployment opening. In the above embodiment, the vertical movement of the pair of vertical rods is associated with the vertical movement of the different inlets.

However, a pair of levers may be used instead of the ingot. In this case the vertical rods are connected at one end of the different levers which alternately oscillate in different vertical directions once per loom cycle.

The advantages resulting from using the present invention in the fabrication of a leno edge weave forming device are as follows.

(Iii) In the present invention, since the leno tilt is twisted around the so-called MAV system, i.e., the periphery, which is associated with each sting yarn, a very strong edge weave is obtained, although the apparatus has a very simple and simple structure.

(Ii) The moving elements are required to move only in the vertical direction, using regular opening movement or similar lever movement. The number of movable elements is therefore very small, which increases the life of the device.

(Iii) Leno slopes are forced to move along the inclined sides of the motor elements, and therefore do not cause intensive wear and tear by contact with the yarn. This greatly extends the life of the motor elements. On top of that, the surface of contact with the yarns of the motor elements can be kept smooth for a long period of time, which significantly prevents fraying and cutting of the yarns.

(Iii) Because the distribution of leno slopes is carried out only by the vertical movement of the moving elements, the relevant moving elements are required to perform only very simple and trouble-free movement. The operation of the device can therefore well follow the high speed operation of the loom. It is also relatively easy to increase the number of lenodans in single edge weaving.

(Iii) The components of the device are very easy to observe and access from the outside, which makes it easy to detect operational accidents and facilitate the device's construction.

(Iii) Damage of the source of yarn can be avoided because there is no forced bending to the yarn during distribution.

(Iii) The yarn is formed by the moving elements and controlled by the narrow and inclined grooves, which can successfully prevent unwanted whipping during dispensing.
