發明所要解決的問題 [4] Problems to be solved by the invention [4]

在利用這種舌針來形成網眼時,會發生將舌針的頂端自針織紗線的線圈抽出的動作。具體而言,形成為,在舌部與鉤部相接觸的鎖閉(knock over)狀態下,針織紗線的線圈沿著舌部的背面朝向針的頂端側脫離。這時,若針織紗線的線圈較小,則存在線圈緊壓舌部和鉤部之間的覆蓋部分,導致舌針和紗線之間的摩擦阻力變大的情況。並且,摩擦阻力的急劇的變動會造成對紗線、針的負載,成為布料、針的破損的原因。When a mesh is formed using such a tongue needle, the tip of the tongue needle is pulled out from the stitches of the knitting yarn. Specifically, the knitting yarn is formed in a knock over state where the tongue portion and the hook portion are in contact with each other along the back surface of the tongue portion toward the tip end side of the needle. At this time, if the stitches of the knitted yarn are small, the stitches may press the covering portion between the tongue portion and the hook portion, and the frictional resistance between the tongue needle and the yarn may increase. In addition, rapid changes in frictional resistance cause loads on the yarns and needles and cause damage to the cloth and needles.

因此,本發明的課題在於提供一種能夠抑制摩擦阻力的急劇的變動的舌針。Therefore, an object of the present invention is to provide a latch needle capable of suppressing a sudden change in friction resistance.

The hook portion is contacted and separated, and the tongue needle is characterized in that in a locked state where the tongue portion and the hook portion are in contact with each other, the loop of the knitting yarn is separated along the back surface of the tongue portion toward the tip side, The needle body has a concave shape on the side opposite to the surface facing the tongue portion, that is, the back surface. When the narrated needle in the locked state is viewed from the side in the axial direction, the concave shape is at least It is set to the position where the said needle main body and the back surface of the said tongue part cross | intersect. [6]

技術方案2記載的發明在上述的技術方案1記載的發明的特徵點的基礎上,其特徵在於,所述凹形狀是所述針主體的背面向內側彎曲而成的形狀。 [7]The invention described in claim 2 is the feature point of the invention described in claim 1, wherein the concave shape is a shape obtained by bending the back surface of the needle body inward. [7]

技術方案3記載的發明在上述的技術方案1或2記載的發明的特徵點的基礎上,其特徵在於,所述凹形狀是在所述針主體的背面形成的倒角形狀。 [8]The invention described in claim 3 is the feature point of the invention described in claim 1 or 2, wherein the concave shape is a chamfered shape formed on a back surface of the needle body. [8]

技術方案4記載的發明在上述的技術方案1~3中任一項記載的發明的特徵點的基礎上,其特徵在於,所述針主體的背面向頂端變細的方向逐漸地傾斜直到頂端為止。 [9]The invention described in claim 4 is the feature point of the invention described in any one of claims 1 to 3, characterized in that the back surface of the needle body is gradually inclined to the direction in which the tip is tapered to the tip. . [9]

技術方案5記載的發明在上述的技術方案1~4中任一項記載的發明的特徵點的基礎上,其特徵在於,在將在前述針主體以及前述舌部的周圍抻起的最短的紗線的長度作為針織紗線的線圈長時,該針織紗線的線圈長在針織紗線的線圈沿著所述舌部的背面向頂端側移動直到自所述舌部脫離為止的過程中逐漸地增加而不減小。The invention described in claim 5 is the feature point of the invention described in any one of claims 1 to 4 above, and is characterized in that the shortest yarn is to be rolled up around the needle body and the tongue.

發明的效果 [10] Effect of the invention [10]

技術方案1記載的發明如上所述,針主體在與面對舌部的面相反的這一側的面即背面具有凹形狀,在自側面沿著軸向觀察鎖閉狀態下的舌針時,凹形狀至少設置到針主體和舌部的背面相交叉的位置為止。採用這樣的結構,能夠在針織紗線的線圈搭在舌部上時使摩擦阻力不急劇地變動。即,在以往的結構中,在鎖閉狀態下針織紗線的線圈沿著舌部的背面向頂端側脫離時,在針織紗線的線圈搭在舌部的背面上並開始滑動時,針織紗線的線圈急劇地擴大,從而摩擦阻力產生急劇的變動。針對該點而言,採用本發明,由於設置有凹形狀,從而即使是剛剛搭在舌部上之後針織紗線的線圈也會平緩地擴大而不會急劇地擴大,因此舌針和紗線之間的摩擦阻力穩定,能夠編織美觀的布料。另外,由於編織阻力較小,因此能夠抑制針織機的消耗電力,並且能夠抑制針的破損。 [11]According to the invention described in claim 1, as described above, the needle body has a concave shape on the side opposite to the surface facing the tongue portion, that is, the back surface. When the latch needle in the locked state is viewed from the side surface in the axial direction, The concave shape is provided at least until the position where the needle body and the back surface of the tongue intersect. With such a structure, it is possible to prevent the frictional resistance from changing abruptly when the loop of the knitting yarn is put on the tongue. That is, in the conventional configuration, when the stitches of the knitted yarn are detached toward the tip side along the back surface of the tongue in the closed state, when the stitches of the knitted yarn are placed on the back surface of the tongue and started to slide, the knitted yarn The coil of the wire is suddenly enlarged, so that the frictional resistance changes sharply. In this regard, according to the present invention, since the concave shape is provided, the loop of the knitting yarn will be gradually expanded even after it is put on the tongue, and it will not be enlarged sharply. The frictional resistance between them is stable, which can weave beautiful fabrics. In addition, since the knitting resistance is small, power consumption of the knitting machine can be suppressed, and breakage of the needle can be suppressed. [11]

另外,技術方案2記載的發明如上所述,凹形狀是針主體的背面向內側彎曲而成的形狀。採用這樣的結構,在針織紗線的線圈在舌部的背面上滑動時,由於線圈的形狀沒有較大地變化,因此能夠抑制摩擦阻力的變動。 [12]In addition, as described in the invention of claim 2, the concave shape is a shape obtained by bending the back surface of the needle body inward. With such a configuration, when the loop of the knitting yarn slides on the back surface of the tongue portion, the shape of the loop does not change greatly, so it is possible to suppress the fluctuation of the frictional resistance. [12]

另外,技術方案3記載的發明如上所述,凹形狀是在針主體的背面形成的倒角形狀。採用這樣的結構,能夠防止針織紗線的線圈急劇地擴大,並且能夠防止紗線在針主體的背面的角部磨損。 [13]In addition, as described in the third aspect of the invention, the concave shape is a chamfered shape formed on the back surface of the needle body. With such a structure, it is possible to prevent the loop of the knitting yarn from rapidly expanding, and to prevent the yarn from being worn at the corner portion of the back surface of the needle body. [13]

另外,技術方案4記載的發明如上所述,針主體的背面向頂端變細的方向逐漸地傾斜直到頂端為止。採用這樣的結構,能夠使針織紗線的線圈易於自舌針的頂端脫離。 [14]In addition, as described in the fourth aspect of the invention, as described above, the back surface of the needle body is gradually inclined toward the tapered end until it reaches the top end. With such a structure, the loop of the knitting yarn can be easily detached from the tip of the tongue. [14]

另外,技術方案5記載的發明如上所述,針織紗線的線圈長在針織紗線的線圈沿著舌部的背面朝向頂端側移動直到自所述舌部脫離為止的過程中逐漸地增加而不減小。採用這樣的結構,由於線圈長在直到線圈自舌針的頂端脫離為止的過程中沒有既增加又減少,因此能夠使線圈長平緩地增加,能夠抑制摩擦阻力的急劇的變動並且能夠使針織紗線的線圈順暢地自舌針的頂端脫離。In addition, as described in the invention of claim 5, as described above, the stitch length of the knitted yarn is gradually increased while the stitch of the knitted yarn moves along the back surface of the tongue toward the tip side until it is detached from the tongue. Decrease. With such a structure, the stitch length does not increase or decrease during the process until the stitch is detached from the tip of the pin, so that the stitch length can be increased gently, rapid changes in friction resistance can be suppressed, and knitting yarns can be made. The coil of the needle detaches smoothly from the tip of the needle.

[17][17]

參照附圖說明本發明的實施例如次:Examples of the present invention will be described with reference to the drawings:

本實施例的舌針10作為針織品編織用的針,安裝於圓型針織機、針織橫機而被使用,如圖1等所示,舌針10包括:針主體11,其在頂端具有鉤狀的鉤部14;以及舌部20,其能夠轉動地安裝於針主體11且能夠與鉤部14接觸、分離。該舌針10通過舌部20的開閉,經過供紗、線圈形成的過程從而編織布料。 [18]The tongue needle 10 of this embodiment is used as a needle for knitting, and is used by being mounted on a circular knitting machine or a flat knitting machine. As shown in FIG. 1 and the like, the tongue needle 10 includes a needle main body 11 having a hook at the top end. The hook portion 14 is shaped like a tongue, and the tongue portion 20 is rotatably attached to the needle body 11 and can be brought into contact with and separated from the hook portion 14. The tongue needle 10 knits cloth by opening and closing the tongue portion 20, and through a process of supplying yarn and forming a loop. [18]

具體而言,該舌針10在針織機的作用下沿著軸向A做進退動作,通過與該進退動作相連動地、交替重複圖1的(b)所示的舌部20與鉤部14相抵接的鎖閉狀態和圖2的(b)所示的舌部20與鉤部14分離且鉤部14開放的開放狀態,從而編織布料。 [19]Specifically, the tongue needle 10 moves forward and backward along the axial direction A under the action of the knitting machine, and alternately repeats the tongue portion 20 and the hook portion 14 shown in FIG. 1 (b) in conjunction with the forward and backward movement. The abutted locked state and the opened state in which the tongue portion 20 and the hook portion 14 are separated from each other and the hook portion 14 is opened as shown in FIG. 2 (b), the cloth is knitted. [19]

例如,通過在針織機的作用下使舌針10沿著軸向A移動,從而使開放狀態下的鉤部14進入針織紗線S的線圈,並在線圈的對面側,利用舌針10的鉤部14鉤起紗線。之後,通過使舌針10向退避方向移動,從而在鉤部14自線圈脫離時,在線圈的作用下舌部20閉合從而成為鎖閉狀態,針織紗線S的線圈沿著舌部20的背面20a朝向頂端側脫離。通過該一系列的動作,能夠使紗線經過線圈從而形成網眼。另外,若再次使舌針10向進入方向移動,則在鉤部14鉤起的紗線的張力的作用下舌部20打開從而成為開放狀態。開放狀態下的舌針10與鉤起的紗線分離,並且進入下一個線圈。 [20]For example, by moving the tongue 10 in the axial direction A under the action of the knitting machine, the hook portion 14 in the open state enters the loop of the knitting yarn S, and the hook of the tongue 10 is used on the opposite side of the loop. The portion 14 hooks the yarn. Thereafter, by moving the tongue needle 10 in the retreating direction, when the hook portion 14 is disengaged from the loop, the tongue portion 20 is closed and locked by the loop, and the loop of the knitting yarn S is along the back of the tongue portion 20 20a is detached toward the tip side. Through this series of operations, the yarn can be passed through the loop to form a mesh. In addition, when the tongue needle 10 is moved in the entering direction again, the tongue portion 20 is opened by the tension of the yarn hooked by the hook portion 14 to be opened. The tongue 10 in the open state is separated from the hooked yarn and enters the next loop. [20]

本實施例的針主體11包括:針杆13,其為棒狀;頰部15,其設置於針杆13的頂端側,用於支承舌部20;以及連接部16,其設置於頰部15和鉤部14之間。在頰部15上設置有轉動軸25,該轉動軸25以舌部20能夠轉動的方式軸支承該舌部20。該轉動軸25能夠通過例如銷、鉚等來形成。另外,如圖1的(b)等所示,連接部16在側視圖中形成為頂端較細的形狀。並且,在該連接部16的頂端設置有彎折成“J”字形的鉤狀的鉤部14。如圖1的(c)等所示,該鉤部14的頂端14a的厚度形成得比連接部16、針杆13薄,並且能進入舌部20的槽部20b(後述)。 [21]The needle main body 11 of this embodiment includes a needle bar 13 that is rod-shaped; a cheek portion 15 that is provided on the tip side of the needle bar 13 to support the tongue portion 20; and a connecting portion 16 that is provided on the cheek portion 15 And the hook portion 14. The cheek portion 15 is provided with a rotation shaft 25 that pivotally supports the tongue portion 20 so that the tongue portion 20 can rotate. The rotation shaft 25 can be formed by, for example, a pin, a riveting, or the like. In addition, as shown in FIG. 1 (b) and the like, the connecting portion 16 is formed in a shape having a thinner tip in a side view. In addition, a hook-shaped hook portion 14 bent into a “J” shape is provided at the tip of the connection portion 16. As shown in FIG. 1 (c) and the like, the thickness of the tip end 14 a of the hook portion 14 is thinner than that of the connection portion 16 and the needle bar 13 and can enter the groove portion 20 b (described later) of the tongue portion 20. [twenty one]

另外,在本實施例中,比圖1的(c)等所示的P1靠頂端側的部分是鉤部14,在P1和P3之間的部分是連接部16,在P3和P7之間的部分是頰部15,比P7靠後端側的部分是針杆13。 [22]In addition, in this embodiment, the portion on the top side of P1 shown in FIG. 1 (c) and the like is the hook portion 14, the portion between P1 and P3 is the connection portion 16, and the portion between P3 and P7 is The part is the cheek part 15 and the part on the rear side than P7 is the needle bar 13. [twenty two]

另外,在本實施例中,舌部20的後端部以自兩側夾入的方式能夠轉動地保持於針主體11的頰部15。另外,在舌部20的頂端部設置有剖面呈大致“V”字形的槽部20b,通過利用該槽部20b來接受鉤部14的頂端14a,從而能夠成為使舌部20與鉤部14相抵接的鎖閉狀態。 [23]In addition, in this embodiment, the rear end portion of the tongue portion 20 is rotatably held by the cheek portion 15 of the needle main body 11 so as to be sandwiched from both sides. In addition, a groove portion 20 b having a substantially “V” shape in cross section is provided at a distal end portion of the tongue portion 20. By using the groove portion 20 b to receive the distal end 14 a of the hook portion 14, the tongue portion 20 and the hook portion 14 can be brought into contact Connected locked state. [twenty three]

該舌部20的背面20a(與面對針主體11的面相反的這一側的面)主要由兩個傾斜面構成。即,為形成在轉動軸25側的後端傾斜部20e和形成在比後端傾斜部20e靠頂端側的位置的頂端傾斜部20d。後端傾斜部20e形成在鎖閉狀態下比頂端傾斜部20d陡的斜面。另外,在該後端傾斜部20e和頂端傾斜部20d之間設置有以曲面(例如R形狀)形成的平緩的山部20c。因此,舌部20的背面20a以在山部20c的兩側傾斜角度發生變化的方式形成。在鎖閉狀態下針織紗線S的線圈沿著舌部20的背面20a朝向頂端側脫離時,首先線圈沿著後端傾斜部20e滑動,之後,經過山部20c,沿著頂端傾斜部20d滑動至舌部20的頂端。 [24]The back surface 20 a of the tongue portion 20 (the surface on the side opposite to the surface facing the needle body 11) is mainly composed of two inclined surfaces. That is, the rear-end inclined portion 20e is formed on the rotation shaft 25 side and the front-end inclined portion 20d is formed on the front-end side of the rear-end inclined portion 20e. The rear-end inclined portion 20 e is formed as an inclined surface which is steeper than the front-end inclined portion 20 d in the locked state. Further, a gentle mountain portion 20c formed in a curved surface (for example, an R shape) is provided between the rear-end inclined portion 20e and the front-end inclined portion 20d. Therefore, the back surface 20a of the tongue part 20 is formed so that the inclination angle may change on both sides of the mountain part 20c. When the stitches of the knitted yarn S are disengaged along the back surface 20a of the tongue portion 20 toward the tip side in the locked state, the stitches first slide along the rear inclined portion 20e, and then, after passing through the mountain portion 20c, slide along the top inclined portion 20d To the top of the tongue 20. [twenty four]

另外,上述的針主體11在與面對舌部20的面相反的這一側的面即背面11a具有凹形狀11b。在自側面沿著軸向A觀察鎖閉狀態下的舌針10時(參照圖1的(b)),該凹形狀11b至少設置到針主體11和舌部20的背面20a相交叉的位置X(P5的線)為止。更詳細地說,該凹形狀11b被設置成至少包括在自側面沿著軸向A觀察鎖閉狀態下的舌針10時自舌部20的山部20c到交叉位置X為止的範圍(自P4到P5的範圍)。 [25]In addition, the above-mentioned needle main body 11 has a concave shape 11 b on the back surface 11 a which is the side opposite to the surface facing the tongue portion 20. When the latch needle 10 in the locked state is viewed from the side along the axial direction A (see FIG. 1 (b)), the concave shape 11 b is provided at least to a position X where the needle body 11 and the back surface 20 a of the tongue portion 20 intersect. (P5 line). In more detail, the concave shape 11b is provided to include at least the range from the mountain portion 20c of the tongue portion 20 to the crossing position X when the latch needle 10 in the locked state is viewed from the side in the axial direction A (from P4 To P5). [25]

在本實施例中,如圖1等所示,凹形狀11b是針主體11的背面11a向內側彎曲而成的形狀。通過設置該凹形狀11b,從而在與舌部20的後端傾斜部20e相對應的位置(自P4到P5的範圍)上,針主體11的背面11a形成為,隨著朝向頂端側去而以稍陡的角度接近舌部20側,在與舌部20的頂端傾斜部20d相對應的位置(自P1到P4的範圍)上,針主體11的背面11a形成為,以比與上述的舌部20的後端傾斜部20e相對應的位置(自P4到P5的範圍)平緩的傾斜面接近舌部20側。 [26]In this embodiment, as shown in FIG. 1 and the like, the concave shape 11 b is a shape obtained by bending the back surface 11 a of the needle body 11 inward. By providing this concave shape 11b, the back surface 11a of the needle main body 11 is formed at a position (range from P4 to P5) corresponding to the rear end inclined portion 20e of the tongue portion 20 so as to move toward the top side. A slightly steeper angle approaches the tongue portion 20 side, and at a position (range from P1 to P4) corresponding to the tip inclined portion 20d of the tongue portion 20, the back surface 11a of the needle body 11 is formed so as to compare with the tongue portion described above. The gentle inclined surface of the position (range from P4 to P5) corresponding to the rear-end inclined portion 20e of 20 is close to the tongue portion 20 side. [26]

另外,在圖7~圖9中所示的以往的構造中,在針織紗線S的線圈通過鎖閉狀態下的舌部20時,有時舌針10和針織紗線S之間會產生急劇的摩擦阻力。 [27]In addition, in the conventional structure shown in FIGS. 7 to 9, when the loop of the knitting yarn S passes through the tongue portion 20 in the locked state, a sharpness may occur between the tongue 10 and the knitting yarn S. Frictional resistance. [27]

圖7的(a)是在相對於針主體11的軸向A垂直的平面上,在將在針主體11以及舌部20的周圍抻起的最短的紗線的長度作為針織紗線S的線圈長時(參照圖7的(c)等),表示該線圈長的增減的曲線圖。另外,圖9是表示P1~P10中的線圈長的表。如這些圖所示,由於在以往的構造中不存在凹形狀11b,因此在自P5到P3的範圍內線圈長急劇增加。像這樣地,由於線圈長急劇增加,從而有時在舌針10和針織紗線S之間會產生急劇的摩擦阻力。另外,在自P5到P3的範圍內線圈長急劇增加後,在P3上線圈長迎來最初的峰值,之後,在自P3到P2的範圍內線圈長減小,之後,再一次在自P2到P1的範圍內線圈長再次增加。由於線圈長像這樣地增減,因此存在摩擦阻力不穩定的問題。 [28](A) of FIG. 7 is a loop of the knitting yarn S on a plane perpendicular to the axial direction A of the needle main body 11 with the length of the shortest yarn curled around the needle main body 11 and the tongue 20 Long time (refer to FIG. 7 (c) and the like) is a graph showing the increase and decrease of the coil length. FIG. 9 is a table showing the coil lengths in P1 to P10. As shown in these figures, since the concave shape 11b does not exist in the conventional structure, the coil length increases sharply in the range from P5 to P3. In this manner, a sharp increase in the loop length may cause a sharp frictional resistance between the tongue 10 and the knitting yarn S. In addition, after the coil length increased sharply in the range from P5 to P3, the coil length ushered in the initial peak on P3, after which the coil length decreased in the range from P3 to P2, and then again from P2 to The coil length increases again in the range of P1. Since the coil length is increased or decreased like this, there is a problem that the frictional resistance is unstable. [28]

針對該點而言,採用本實施例,如圖1的(a)、圖3所示,在自P5到P1的範圍內線圈長逐漸地增加。換言之,本實施例的線圈長構成為在針織紗線S的線圈沿著舌部20的背面20a朝向頂端側移動直到自舌部20脫離為止的過程中逐漸地增加而不減小。採用這樣的結構,能夠使線圈長平緩地增加,能夠抑制摩擦阻力的急劇的變動並且能夠使針織紗線S的線圈順暢地自舌針10的頂端脫離。另外,由於在直到線圈自舌針10的頂端脫離為止的過程中線圈長沒有既增加又減少,因此能夠使摩擦阻力穩定。 [29]In this regard, with this embodiment, as shown in FIG. 1 (a) and FIG. 3, the coil length gradually increases in a range from P5 to P1. In other words, the stitch length of the present embodiment is configured such that the stitch length of the knitting yarn S gradually increases and does not decrease in the process of moving the stitches of the knitting yarn S along the back surface 20 a of the tongue portion 20 toward the tip side until the stitches are separated from the tongue portion 20. With such a configuration, the stitch length can be increased gradually, the sharp change in friction resistance can be suppressed, and the stitches of the knitting yarn S can be smoothly separated from the tip of the tongue 10. In addition, since the coil length does not increase or decrease during the process until the coil is disengaged from the tip of the pin 10, the frictional resistance can be stabilized. [29]

並且,由於本實施例的針主體11的背面11a向頂端變細的方向逐漸地傾斜直到頂端,因此針織紗線S的線圈能夠順暢地自舌針10的頂端脫離而不會在離開舌部20後鉤掛於針主體11的背面11a。 [30]In addition, since the back surface 11a of the needle body 11 of the present embodiment is gradually inclined toward the top end in a tapering direction until the top end, the loop of the knitting yarn S can be smoothly detached from the top end of the tongue 10 without leaving the tongue 20 The rear hook is hooked on the back surface 11 a of the needle body 11. [30]

另外,在上述的實施例實施例中,將凹形狀11b形成為針主體11的背面11a向內側彎曲而成的形狀,但是不限定於此。即,也可以是,代替彎曲而成的形狀,或者在彎曲而成的形狀的基礎上,將在針主體11的背面11a上形成的倒角形狀作為凹形狀11b。具體而言,如圖4~圖6所示,也可以通過對針主體11的背面11a側的角部進行倒角來形成凹形狀11b。 [31]In addition, in the embodiment described above, the concave shape 11 b is formed into a shape in which the back surface 11 a of the needle body 11 is bent inward, but it is not limited to this. That is, a chamfered shape formed on the back surface 11a of the needle body 11 may be used as the concave shape 11b instead of the curved shape or in addition to the curved shape. Specifically, as shown in FIGS. 4 to 6, a concave shape 11 b may be formed by chamfering a corner portion on the back surface 11 a side of the needle body 11. [31]

像以上說明的那樣,採用本實施例,針主體11在與面對舌部20的面相反的這一側的面即背面11a具有凹形狀11b,在自側面沿著軸向A觀察鎖閉狀態下的舌針10時,凹形狀11b至少設置到針主體11和舌部20的背面20a相交叉的位置為止。採用這樣的結構,能夠在針織紗線S的線圈搭在舌部20上時不使摩擦阻力急劇地變動。即,在以往的結構中,在鎖閉狀態下針織紗線S的線圈沿著舌部20的背面20a朝向頂端側脫離時,在針織紗線S的線圈搭在舌部20的背面20a上並開始滑動時,針織紗線S的線圈急劇地擴大,並且摩擦阻力產生了急劇的變動。針對該點而言,採用本實施例,由於設置有凹形狀11b,因而即使是剛剛搭在舌部20上之後針織紗線S的線圈也會平緩地擴大而不會急劇地擴大,因此舌針10和針織紗線S之間的摩擦阻力穩定,能夠編織美觀的布料。另外,由於編織阻力較小,因此能夠抑制針織機的消耗電力,並且能夠抑制舌針10的破損。As described above, according to this embodiment, the needle body 11 has a concave shape 11b on the back surface 11a, which is the side opposite to the surface facing the tongue 20, and the locked state is viewed from the side along the axial direction A. When the tongue needle 10 is lowered, the concave shape 11 b is provided at least until the needle body 11 and the back surface 20 a of the tongue portion 20 intersect. With such a structure, it is possible to prevent the frictional resistance from changing sharply when the loop of the knitting yarn S is placed on the tongue portion 20. That is, in the conventional configuration, when the stitches of the knitted yarn S are detached toward the distal end side along the back surface 20 a of the tongue portion 20 in the closed state, the stitches of the knitted yarn S are put on the back surface 20 a of the tongue portion 20 and When slipping was started, the stitches of the knitting yarn S suddenly expanded, and the frictional resistance fluctuated sharply. In this regard, according to this embodiment, since the concave shape 11b is provided, the stitches of the knitting yarn S will gradually expand without sharply expanding even after the tongue 20 is simply put on the tongue 20. Therefore, the latch needle The frictional resistance between 10 and knitting yarn S is stable, and it can knit beautiful fabrics. In addition, since the knitting resistance is small, power consumption of the knitting machine can be suppressed, and breakage of the tongue needle 10 can be suppressed.
