Description

本発明は、固定シンカーを有する横編機に関し、詳しくは、固定シンカーの取付精度の向上を図る対策に係る。   The present invention relates to a flat knitting machine having a fixed sinker, and more particularly, to measures for improving the mounting accuracy of the fixed sinker.

従来より、図３に示すように、横編機１の針床１１の先端部に固定シンカー２が複数並設され、この各固定シンカー２に、尾端に嵌め込み部２３を有して長手方向中途部が高さ方向へ屈曲する本体部２１と、本体部２１の先端側のシンカー先端側支持部２５より歯口Ｇ側に突出する頭部２２とを備えたものは知られている（特許文献１参照）。また、針床１１の先端部には、本体部２１の並設方向に延びるワイヤー３１の軸ｍ回りにシンカー先端側支持部２５を支持して頭部２２を歯口中心Ｇａに対して接離方向へ揺動させる針床先端側支持部１２と、ワイヤー３１の軸ｍ回りにシンカー先端側支持部２５が支持された状態で本体部２１の屈曲部分２４を高さ方向へ撓ませた際のばね力によって本体部２１の尾端の嵌め込み部２３をスナップフィットにより装着させるスナップフィット用凹部１３とが設けられている。この場合、本体部２１の長手方向中途部が屈曲する高さ方向は、スナップフィット用凹部１３に対する嵌め込み部２３の装着方向と一致している。   Conventionally, as shown in FIG. 3, a plurality of fixed sinkers 2 are juxtaposed at the tip of the needle bed 11 of the flat knitting machine 1, and each fixed sinker 2 has a fitting portion 23 at the tail end in the longitudinal direction. A device including a body portion 21 whose midway portion is bent in the height direction and a head portion 22 that protrudes toward the tooth opening G side from the sinker tip side support portion 25 on the tip side of the body portion 21 is known (patent) Reference 1). Further, the tip portion of the needle bed 11 supports the sinker tip side support portion 25 around the axis m of the wire 31 extending in the direction in which the main body portion 21 is juxtaposed, and the head portion 22 is brought into contact with and separated from the tooth center Ga. When the bent portion 24 of the main body 21 is bent in the height direction in a state where the needle bed tip side support portion 12 that swings in the direction and the sinker tip side support portion 25 is supported around the axis m of the wire 31. There is provided a snap-fit recess 13 for mounting the fitting portion 23 at the tail end of the main body 21 by a spring force. In this case, the height direction in which the midway portion in the longitudinal direction of the main body portion 21 is bent coincides with the mounting direction of the fitting portion 23 with respect to the snap-fit concave portion 13.

特許第４３４８２８６号公報Japanese Patent No. 4348286

ところで、スナップフィット用凹部１３は、針床１１の先端部の下面に凹設され、本体部２１の屈曲部分２４を撓ませた際のばね力によって、嵌め込み部２３を底面１３１及び先端側面１３２に対し当接させている。その場合、針床１１及び固定シンカー２の加工精度が共に許容公差範囲内であっても、先端側面１３２に対する嵌め込み部２３の当たり加減に差が生じている。   By the way, the snap fit recess 13 is recessed in the lower surface of the distal end portion of the needle bed 11, and the fitting portion 23 is formed on the bottom surface 131 and the distal end side surface 132 by a spring force when the bent portion 24 of the main body portion 21 is bent. They are in contact with each other. In that case, even if the processing accuracy of the needle bed 11 and the fixed sinker 2 is both within the allowable tolerance range, there is a difference in the amount of contact of the fitting portion 23 with respect to the distal end side surface 132.

このとき、先端側面１３２に対する嵌め込み部２３の当たり加減の強弱によって、予め設計上において定められた基準位置に対し頭部２２の位置がばらついてしまう。この固定シンカー２の頭部２２の位置は、前後の針床１１を取り付ける際に基準となるため、より高い精度が要求されている。   At this time, the position of the head 22 varies with respect to a reference position determined in advance by design, depending on whether the fitting portion 23 is in contact with the distal end side surface 132 or not. Since the position of the head 22 of the fixed sinker 2 is a reference when the front and back needle beds 11 are attached, higher accuracy is required.

本発明の目的は、前後の針床を取り付ける際に基準となる頭部の位置を基準位置に対し高い精度で近付けることができる固定シンカーを有する横編機を提供することにある。   An object of the present invention is to provide a flat knitting machine having a fixed sinker that can bring the position of the head serving as a reference close to the reference position with high accuracy when attaching the front and back needle beds.

前記目的を達成するため、本発明では、針床の先端部に並設され、かつ尾端に嵌め込み部を有して長手方向中途部が屈曲された本体部の先端より頭部が歯口側に向かって突出する固定シンカーを有している。更に、前記本体部の並設方向に延びるワイヤーの軸回りに当該本体部のシンカー先端側支持部を支持しかつそのワイヤーの軸回りに前記頭部を歯口中心に対する接離方向へ揺動させる針床先端側支持部を前記針床の先端部に設けるとともに、前記針床先端側支持部にシンカー先端側支持部を支持した状態で前記本体部の屈曲部分を撓ませた際のばね力によって前記本体部の尾端の嵌め込み部を底面及び先端側面に対しスナップフィットにより装着させるスナップフィット用凹部を前記針床の先端部の下面に凹設した横編機を前提とする。そして、前記針床の先端部に、前記本体部に向かって開口し、かつ当該本体部の並設方向から挿通される線状材を支持する線状材用支持部を設け、前記線状材を前記線状材用支持部に挿通した際に当該線状材と当接する前記本体部の屈曲部分よりも先端側の当接部分を歯口中心側へ押圧して前記頭部を前記ワイヤーの軸回りに歯口中心から離反する方向へ揺動させることを特徴としている。   In order to achieve the above-mentioned object, in the present invention, the head is located on the side of the mouth side of the tip of the main body that is provided in parallel with the tip of the needle bed and has a fitting portion at the tail and bent in the longitudinal direction. A fixed sinker protruding toward Further, the sinker tip side support portion of the main body portion is supported around the axis of the wire extending in the direction in which the main body portions are arranged in parallel, and the head portion is swung in the contact / separation direction with respect to the center of the tooth opening around the wire axis. A needle bed tip side support portion is provided at the tip portion of the needle bed, and a spring force is applied when the bent portion of the main body portion is bent in a state where the needle bed tip side support portion supports the sinker tip side support portion. It is premised on a flat knitting machine in which a snap-fit concave portion for fitting a fitting portion at the tail end of the main body portion to the bottom surface and the side surface of the front end by snap fitting is provided in the lower surface of the front end portion of the needle bed. And, at the tip of the needle bed, there is provided a linear material support portion that supports the linear material that opens toward the main body portion and is inserted from the juxtaposed direction of the main body portion. When the wire is inserted into the linear material support portion, the abutting portion on the distal end side of the bent portion of the main body portion that abuts on the linear material is pressed toward the center of the tooth opening, and the head portion of the wire is It is characterized in that it is swung around the axis in a direction away from the center of the mouth.

また、前記線状材用支持部と前記針床先端側支持部とを、前記針床の先端部において前記歯口側に向かってそれぞれ開口させ、当該両支持部の支持面同士を互いに平行とすることがこのましい。   Further, the linear material support portion and the needle bed distal end side support portion are respectively opened toward the tooth mouth side at the distal end portion of the needle bed, and the support surfaces of the both support portions are parallel to each other. This is good to do.

また、前記嵌め込み部に、前記スナップフィット用凹部の底面及び先端側面に対しそれぞれ点接触する円弧状部分を備えることがこのましい。   In addition, it is preferable that the fitting portion includes arc-shaped portions that make point contact with the bottom surface and the tip side surface of the snap-fit recess.

更に、前記本体部の屈曲部分から前記嵌め込み部までの間に、その屈曲部分から嵌め込み部に近付くに従い上下方向の厚みが小さくなるようにテーパーを付けることがこのましい。   Further, it is preferable that a taper is provided between the bent portion of the main body portion and the fitting portion so that the thickness in the vertical direction decreases as the bent portion approaches the fitting portion.

針床の線状材用支持部に挿通した線状材と当接する本体部の当接部分を線状材で歯口中心側へ押圧することで、ワイヤーの軸回りに頭部が歯口中心から離反する方向へ揺動し、基準位置に対して頭部の位置が安定する。これにより、前後の針床を取り付ける際に基準となる頭部の位置を基準位置に対して高い精度で近付けることができる。   The head part is centered around the axis of the wire by pressing the contact part of the main body part that contacts the linear material inserted into the linear material support part of the needle bed with the linear material toward the central side of the oral cavity. The head position is stabilized with respect to the reference position. Thereby, when attaching the front and back needle beds, the position of the head serving as a reference can be brought close to the reference position with high accuracy.

また、針床の先端部において線状材用支持部及び先端側支持部をそれぞれ歯口側に向かって開口させ、当該両支持部の支持面同士を互いに平行とすることで、線状材用支持部と先端側支持部とをそれぞれ支持面に沿って歯口側から加工することができ、線状材用支持部及び先端側支持部の加工精度を向上させることができる。   Further, the linear material support portion and the distal end side support portion are opened toward the tooth mouth side at the distal end portion of the needle bed, and the support surfaces of both the support portions are parallel to each other, thereby The support part and the tip side support part can be processed along the support surface from the mouth side, and the processing accuracy of the linear material support part and the tip side support part can be improved.

また、スナップフィット用凹部の底面及び先端側面に対し嵌め込み部を円弧状部分によってそれぞれ点接触させることで、嵌め込み部をスナップフィット用凹部の底面及び先端側面に対しそれぞれ精度よく当接させることができる。   Further, the fitting portions can be brought into contact with the bottom surface and the tip side surface of the snap fit recess with high accuracy by making point contact of the fitting portions with the arc-shaped portions with respect to the bottom surface and the tip side surface of the snap fit recess. .

更に、本体部の屈曲部分から嵌め込み部までの間に、嵌め込み部に近付くに従い上下方向の厚みが小さくなるようにテーパーを付けることで、屈曲部分に作用する応力が本体部の屈曲部分から嵌め込み部までの間にも分散され、屈曲部分に対する応力集中を回避することができる。   Furthermore, by applying a taper between the bent part of the main body part and the fitting part so that the thickness in the vertical direction decreases as it approaches the fitting part, the stress acting on the bent part is applied from the bent part of the main body part to the fitting part. The stress concentration on the bent portion can be avoided.

図１及び図２において、横編機１は、前後一対の針床１１（一方のみ示す）を備え、前後の針床１１間での編目の目移しを可能としている。この針床１１の先端部には、長手方向中途部が高さ方向へ屈曲された本体部２１の先端より頭部２２が突出する固定シンカー２（図では１つのみ示す）が複数並設されている。各固定シンカー２の本体部２１の尾端には、略矩形状の嵌め込み部２３が設けられている。この場合、歯口中心Ｇａは、前後の針床１１間の中間位置を鉛直方向に延びている。   1 and 2, the flat knitting machine 1 includes a pair of front and back needle beds 11 (only one is shown), and enables stitch transfer between the front and back needle beds 11. A plurality of fixed sinkers 2 (only one is shown in the figure) are juxtaposed at the distal end portion of the needle bed 11 so that the head portion 22 projects from the distal end of the main body portion 21 whose middle portion in the longitudinal direction is bent in the height direction. ing. A fitting portion 23 having a substantially rectangular shape is provided at the tail end of the main body portion 21 of each fixed sinker 2. In this case, the tooth center Ga extends vertically in the middle between the front and back needle beds 11.

針床１１の先端部には、各固定シンカー２の本体部２１の先端を支持する針床先端側支持部１２が設けられている。この針床先端側支持部１２は、上方及び歯口Ｇ側に向かってそれぞれ開口する断面略Ｌ字状の切欠によって構成されている。また、針床先端側支持部１２は、針床１１の先端部において当該針床１１の底面と略平行に歯口Ｇ側に向かって延びる支持面１２１を有している。一方、本体部２１の先端には、尾端側（図１及び図２では左側）に断面形状が開口するシンカー先端側支持部２５が設けられている。そして、針床先端側支持部１２には、各固定シンカー２の本体部２１の並設方向（紙面手前奥方向）に延びる断面円形状の第１ワイヤー３１が挿通され、この第１ワイヤー３１の軸ｍ回りにシンカー先端側支持部２５が支持されて頭部２２を歯口中心Ｇａに対して接離方向へ揺動可能としている。このとき、頭部２２は、各固定シンカー２の本体部２１の並設方向に延びる断面円形状の第２ワイヤー３２が挿通された状態で、第１ワイヤー３１の軸ｍ回りの歯口中心Ｇａに対する接離方向への揺動が許容されている。   A needle bed tip side support portion 12 that supports the tip of the main body portion 21 of each fixed sinker 2 is provided at the tip portion of the needle bed 11. The needle bed tip side support portion 12 is constituted by a cutout having a substantially L-shaped cross section that opens upward and toward the tooth opening G side. Further, the needle bed distal end side support portion 12 has a support surface 121 extending toward the tooth opening G side substantially parallel to the bottom surface of the needle bed 11 at the distal end portion of the needle bed 11. On the other hand, a sinker tip side support portion 25 whose cross-sectional shape is open on the tail end side (left side in FIGS. 1 and 2) is provided at the tip of the main body portion 21. The needle bed tip side support portion 12 is inserted with a first wire 31 having a circular cross section extending in the direction in which the main body portions 21 of the fixed sinkers 2 are juxtaposed (the front and back direction in the drawing). A sinker tip side support portion 25 is supported around the axis m, and the head portion 22 can be swung in the contact / separation direction with respect to the tooth center Ga. At this time, the head 22 has a tooth center Ga around the axis m of the first wire 31 with the second wire 32 having a circular cross section extending in the direction in which the main body portions 21 of the fixed sinkers 2 are juxtaposed. Oscillation in the contact / separation direction with respect to is allowed.

また、針床１１の先端部の下面には、針床先端側支持部１２に第１ワイヤー３１を介してシンカー先端側支持部２５が支持された本体部２１の嵌め込み部２３をスナップフィットにより装着するスナップフィット用凹部１３が設けられている。スナップフィット用凹部１３は、底面１３１と、この底面１３１の先端及び尾端に連続する先端側面１３２及び尾端側面１３３とを備えている。また、嵌め込み部２３は、針床先端側支持部１２にシンカー先端側支持部２５が第１ワイヤー３１を介して支持された状態で屈曲部分２４を撓ませた際のばね力によってスナップフィット用凹部１３の底面１３１と先端側面１３２とにスナップフィットにより装着される。また、嵌め込み部２３の略中心部には、各固定シンカー２の本体部２１の並設方向に延びる断面円形状の第３ワイヤー３３が挿通されている。   Further, the fitting portion 23 of the main body portion 21 in which the sinker tip side support portion 25 is supported by the needle bed tip side support portion 12 via the first wire 31 is attached to the lower surface of the tip portion of the needle bed 11 by a snap fit. A snap fit recess 13 is provided. The snap-fit recess 13 includes a bottom surface 131, a tip side surface 132 and a tail end side surface 133 that are continuous with the tip and tail ends of the bottom surface 131. Further, the fitting portion 23 is a snap-fit concave portion due to a spring force when the bent portion 24 is bent while the sinker tip side support portion 25 is supported by the needle bed tip side support portion 12 via the first wire 31. 13 are attached to the bottom surface 131 and the tip side surface 132 by snap fitting. In addition, a third wire 33 having a circular cross section extending in the direction in which the main body portions 21 of the fixed sinkers 2 are arranged is inserted in the substantially central portion of the fitting portion 23.

更に、本体部２１の屈曲部分２４よりもシンカー先端側支持部２５側に位置する針床１１の先端部の下面には、本体部２１の並設方向から挿通される断面円形状の線状材３４を支持する線状材用支持部１４が設けられている。この線状材用支持部１４は、本体部２１側に向かって開口するように下方及び歯口Ｇ側に向かってそれぞれ開口する断面略Ｌ字状の切欠によって構成されている。この場合、第１〜第３ワイヤー３１〜３３及び線状材３４は、鋼線や高強度な樹脂、又は繊維強化複合材料などでもよい。   Further, a linear member having a circular cross section that is inserted from the parallel direction of the main body 21 to the lower surface of the front end of the needle bed 11 located closer to the sinker front end support 25 than the bent portion 24 of the main body 21. The support member 14 for linear material which supports 34 is provided. The linear material support portion 14 is configured by a notch having a substantially L-shaped cross section that opens downward and toward the tooth opening G so as to open toward the main body portion 21 side. In this case, the first to third wires 31 to 33 and the linear member 34 may be steel wires, high-strength resins, fiber reinforced composite materials, or the like.

また、線状材用支持部１４は、針床１１の先端部において当該針床１１の底面と略平行に歯口Ｇ側に向かって延びる支持面１４１を有している。この支持面１４１と、針床先端側支持部１２の支持面１２１とは、互いに平行となっている。これにより、針床先端側支持部１２及び線状材用支持部１４を同時又は個別にそれぞれ支持面１２１，１４１に沿って同じ歯口Ｇ側から加工することができ、針床先端側支持部１２及び線状材用支持部１４の加工精度を向上させることができる。   Further, the linear material support portion 14 has a support surface 141 that extends toward the tooth opening G side substantially parallel to the bottom surface of the needle bed 11 at the distal end portion of the needle bed 11. The support surface 141 and the support surface 121 of the needle bed distal end side support portion 12 are parallel to each other. Thereby, the needle bed tip side support part 12 and the linear material support part 14 can be processed simultaneously or individually from the same tooth opening G side along the support surfaces 121 and 141, respectively. The processing accuracy of the support member 14 and the linear material support portion 14 can be improved.

そして、線状材３４を線状材用支持部１４の角部に挿通した際に当該線状材３４と当接する本体部２１の屈曲部分２４よりもシンカー先端側支持部２５側の当接部分２７を歯口中心Ｇａ側（図１に実線で示す矢印方向）へ押圧して屈曲部分２４の撓みを抑制し、頭部２２を第１ワイヤー３１の軸ｍ回りに歯口中心Ｇａから離反する方向（図１に実線で示す矢印方向）へ揺動させることで、基準位置に対して頭部２２の位置を安定させている。これにより、前後の針床１１を取り付ける際に基準となる頭部２２の位置を基準位置に対して高い精度で近付けることができる。   When the linear material 34 is inserted into the corner of the linear material support portion 14, the contact portion on the sinker tip side support portion 25 side rather than the bent portion 24 of the main body portion 21 that contacts the linear material 34. 27 is pressed toward the mouth center Ga side (in the direction indicated by the solid line in FIG. 1) to suppress bending of the bent portion 24, and the head 22 is separated from the mouth center Ga around the axis m of the first wire 31. By swinging in the direction (arrow direction indicated by the solid line in FIG. 1), the position of the head 22 is stabilized with respect to the reference position. Thereby, when attaching the front and back needle beds 11, the position of the head 22 serving as a reference can be brought close to the reference position with high accuracy.

このとき、線状材３４としては、例えば０．９ｍｍを基準にして±０．０２ｍｍ毎に径を異ならせた複数種類のものが用意されている。そして、嵌め込み部２３をスナップフィットにより装着させた際に第１ワイヤー３１の軸ｍ回りに傾いて基準位置よりも歯口中心Ｇａ側へ近付く頭部２２を、当接部分２７の歯口中心Ｇａ側への押圧によって第１ワイヤー３１の軸ｍ回りに歯口中心Ｇａから離反する方向へ揺動させて基準位置に近付けるための線状材３４が複数種類の中から選択される。   At this time, as the linear material 34, for example, a plurality of types having different diameters every ± 0.02 mm with respect to 0.9 mm are prepared. Then, when the fitting portion 23 is attached by snap fitting, the head 22 that is tilted around the axis m of the first wire 31 and approaches the tooth center Ga side of the reference position is connected to the tooth center Ga of the contact portion 27. A linear member 34 is selected from a plurality of types for swinging in the direction away from the tooth center Ga around the axis m of the first wire 31 by pressing toward the side to approach the reference position.

また、嵌め込み部２３は、スナップフィット用凹部１３の底面１３１と先端側面１３２との角部に対応する角部より突設され、かつスナップフィット用凹部１３への嵌め込み時にその底面１３１及び先端側面１３２に対しそれぞれ点接触する円弧状部分２６を備えている。これにより、嵌め込み部２３をスナップフィット用凹部１３の底面１３１及び先端側面１３２に対しそれぞれ精度よく当接させることができる。   The fitting portion 23 protrudes from a corner portion corresponding to the corner portion between the bottom surface 131 and the tip side surface 132 of the snap fit recess portion 13, and the bottom surface 131 and the tip side surface 132 are inserted into the snap fit recess portion 13. Are provided with arc-shaped portions 26 that are in point contact with each other. Thereby, the fitting part 23 can be made to contact | abut each with respect to the bottom face 131 and the front end side surface 132 of the recessed part 13 for snap fits each with sufficient precision.

更に、本体部２１の屈曲部分２４から嵌め込み部２３までの間の上面には、その屈曲部分２４から嵌め込み部２３に近付くに従い上下方向の厚みが若干小さくなるように僅かにテーパーが付けられている。この本体部２１の屈曲部分２４から嵌め込み部２３までの間のテーパー率は、例えば５０ｍｍあたりの高さ方向の寸法が１〜２ｍｍ小さくなるように１／５０〜２／５０程度に設定されている。これにより、屈曲部分２４を撓ませた際に当該屈曲部分２４に作用する応力が本体部２１の屈曲部分２４から嵌め込み部２３までの間にも分散され、屈曲部分２４に対する応力集中を回避することができる。なお、屈曲部分２４から嵌め込み部２３までの間での上面のみに限らず、嵌め込み部２３側（尾端側）に近付くに従い上下方向の厚みが若干小さくなるように下面のみ又は上下両面共に僅かなテーパーが付けられていてもよい。また、本体部２１の屈曲部分２４から嵌め込み部２３までの間のテーパー率は、１／５０〜２／５０程度に限定されるものではなく、固定シンカーの材質や屈曲部分へ作用する応力値などに応じてテーパー率を設定すればよい。   Further, the upper surface between the bent portion 24 and the fitting portion 23 of the main body 21 is slightly tapered so that the thickness in the vertical direction becomes slightly smaller as the bent portion 24 approaches the fitting portion 23. . The taper ratio between the bent portion 24 and the fitting portion 23 of the main body 21 is set to about 1/50 to 2/50 so that the dimension in the height direction per 50 mm is reduced by 1 to 2 mm, for example. . Thereby, when the bent portion 24 is bent, the stress acting on the bent portion 24 is distributed also between the bent portion 24 and the fitting portion 23 of the main body portion 21, and stress concentration on the bent portion 24 is avoided. Can do. Not only the upper surface between the bent portion 24 and the fitting portion 23, but only the lower surface or both upper and lower surfaces are slightly small so that the thickness in the vertical direction becomes slightly smaller as the fitting portion 23 side (tail end side) is approached. A taper may be attached. Further, the taper ratio between the bent portion 24 and the fitting portion 23 of the main body portion 21 is not limited to about 1/50 to 2/50, but the material of the fixed sinker, the stress value acting on the bent portion, etc. The taper rate may be set according to the above.

ところで、針床１１及び固定シンカー２の加工精度が共に許容公差範囲内であっても、先端側面１３２に対する嵌め込み部２３の当たり具合が強くなる傾向となるように予め設定していてもよい。このとき、先端側面１３２に対する嵌め込み部２３の強い当たり具合によって、本体部２１が尾端側へ強く引き寄せられ、頭部２２が第１ワイヤー３１の軸ｍ回りに傾いて基準位置よりも歯口中心Ｇａ側へ近付く傾向となっている。このため、線状材３４を線状材用支持部１４の角部に挿通すれば、歯口中心Ｇａ側へ近付く頭部２２を第１ワイヤー３１の軸ｍ回りに歯口中心Ｇａから離反する方向へ円滑に揺動させて、頭部２２の位置を基準位置に対してより高い精度で近付けることができる。   By the way, even if the processing accuracy of both the needle bed 11 and the fixed sinker 2 is within the allowable tolerance range, the needle bed 11 and the fixed sinker 2 may be set in advance so that the contact of the fitting portion 23 with the tip side surface 132 tends to be strong. At this time, due to the strong contact of the fitting portion 23 with respect to the distal end side surface 132, the main body portion 21 is strongly pulled toward the tail end side, and the head portion 22 is tilted around the axis m of the first wire 31, and the center of the mouth is more than the reference position. It tends to approach the Ga side. For this reason, if the linear material 34 is inserted into the corner of the linear material support portion 14, the head 22 approaching the side of the tooth center Ga is separated from the tooth center Ga around the axis m of the first wire 31. By smoothly swinging in the direction, the position of the head 22 can be brought closer to the reference position with higher accuracy.

なお、前記実施の形態では、前後一対の針床１１を備えた横編機１に用いられる固定シンカー２について述べたが、前後の少なくとも一方に上下二段の針床を備えた横編機に用いられる固定シンカーに適用されていてもよい。また、針床の先端部の編針間において可動シンカーと共に複数並設される固定シンカーに適用されていてもよい。   In the above-described embodiment, the fixed sinker 2 used in the flat knitting machine 1 including the pair of front and back needle beds 11 is described. However, the flat knitting machine includes two upper and lower needle beds in the front and rear. It may be applied to the fixed sinker used. Further, the present invention may be applied to a plurality of fixed sinkers arranged in parallel with the movable sinker between the knitting needles at the tip of the needle bed.
