横編機の経糸切断'保持方法および装置  Method and apparatus for holding warp cutting of flat knitting machine
技術分野  Technical field
[0001] 本発明は、針床に並設される編針に緯糸を供給してコース編成を繰返しながら、編 針に経糸を挿入可能な横編機の経糸切断'保持方法および装置に関する。  The present invention relates to a warp cutting 'holding method and apparatus for a flat knitting machine capable of inserting a warp into a knitting needle while supplying a weft to knitting needles arranged side by side on a needle bed and repeating course knitting.
背景技術  Background art
[0002] 従来から、緯編地を編成する横編機で、経編地に類似の組織を編成可能とするた めに、横編機に経糸用の編糸供給装置を設けるようにしている(たとえば、特許第 34 52639号公報参照。;)。この編糸供給装置のような経糸挿入機構では、板状のレー スバーに複数の給糸管を着脱可能としておき、レースバーを針床の長手方向に移動 させるラッピングと、長手方向に垂直に振るスイングとを行わせて、各給糸管から経糸 となる編糸を供給する。スイングは、歯口で編針の上方と下方となるように、 2ポジショ ンの間で行われる。レースバーのラッピングで、複数の編針に経糸を供給し、編針で 編成を行えば、部分的な緯編地を編成することもできる。レースバーには複数の給糸 管を装着することができるので、経糸挿入機構を用いると、編み幅方向を多くの区間 に分けて編成する編地を得ることもできる。  Conventionally, a flat knitting machine for knitting a weft knitted fabric has been provided with a knitting yarn supply device for warp in a flat knitting machine in order to be able to knitting a structure similar to a warp knitted fabric. (For example, see Japanese Patent No. 34 52639;). In a warp insertion mechanism such as this knitting yarn supply device, a plurality of yarn supply pipes can be attached to and detached from a plate-shaped race bar, and wrapping that moves the lace bar in the longitudinal direction of the needle bed and swings perpendicularly in the longitudinal direction. Swing is performed to supply knitting yarn as warp from each yarn feeder. The swing is performed between the two positions so that it is above and below the knitting needle at the mouth. A partial weft knitted fabric can be knitted by supplying warp to a plurality of knitting needles and knitting with knitting needles by wrapping the lace bar. Since a plurality of yarn supply pipes can be attached to the lace bar, using a warp insertion mechanism, it is possible to obtain a knitted fabric that is knitted by dividing the knitting width direction into many sections.
横編機では、緯糸となる編糸を、ガーメント単位の編地の編成後に切断を行うカツタ 、および端部の保持を行うグリッパが設けられている(たとえば、特許第 2547683号 公報参照。 ) oなお、ガーメント単位で編地を切り離す際に、編成された編地の始端と 末端とが解れないようにする解れ止め方法も知られている(たとえば、特許第 30993 04号公報参照。)ので、必要に応じて利用することができる。さらに、新たな編地の編 成開始を円滑に行うための編み出し方法も開示されている(たとえば、特公平 3— 77 298号公報参照。)。  A flat knitting machine is provided with a cutter that cuts knitting yarn that becomes a weft after knitting a garment unit, and a gripper that holds an end (see, for example, Japanese Patent No. 2547683). In addition, there is a known method for preventing unraveling of the knitted fabric at the garment unit so that the start and end of the knitted fabric are not unraveled (see, for example, Japanese Patent No. 3099304). It can be used as needed. In addition, a method for setting up a new knitted fabric smoothly is disclosed (for example, see Japanese Examined Patent Publication No. 3-77 298).
経糸挿入機構を備える横編機でも、緯糸については、ガーメント単位の編地を、特 許第 2547683号公報、特許第 3099304号公報、特公平 3— 77298号公報などに 開示されているような、切断'保持と編出し、さらに必要に応じて解れ止めの技術を適 用すれば、編糸を切断しながら編成することができる。たとえば、セータの身頃編地 などでは、編幅が変化する。一般の身頃編地では、裾幅に比べて肩幅が狭くなるの で、編み幅を変化させる成形編みを行う必要がある。また、編地の編み出し時には、 歯口の下方へ引き下げる必要があるけれども、編幅が拡大する部分では、充分な引 き下げを行うことができない。特に、ガーメント単位の身頃編地が肩幅の編成で終了 し、次の身頃編地の裾幅の編成を開始する部分では、ガーメント間にわたって、連続 して編成を行うと、引き下げ力を円滑に作用させるために、捨て編みなどを多く行う必 要があり、効率が良くない。編糸をガーメント単位で切り離すことによって、新たに編 成を開始する編地の編み出しなどの処理を必要としても、総合的には効率よく編地を 編成することができる。 Even in a flat knitting machine equipped with a warp insertion mechanism, for wefts, a garment unit knitted fabric is disclosed in Japanese Patent No. 2547683, Japanese Patent No. 3099304, Japanese Patent Publication No. 3-77298, etc. If cutting and holding and knitting are applied, and if necessary, the technology of unwinding is applied, the knitting yarn can be knitted while being cut. For example, the body knitted fabric of theta For example, the knitting width changes. In general body knitted fabrics, the shoulder width is narrower than the hem width, so it is necessary to perform forming knitting to change the knitting width. In addition, when the knitted fabric is set up, it is necessary to pull it down below the mouth of the knitted fabric, but it cannot be pulled down sufficiently at the portion where the knitting width is widened. In particular, when the garment unit body knitted fabric ends with the shoulder width knitting and the knitting width of the next body knitted fabric starts knitting continuously across the garment, the pulling force works smoothly. For this purpose, it is necessary to perform a lot of knitting, etc., which is not efficient. By separating the knitting yarns in units of garment, the knitted fabric can be knitted efficiently and comprehensively even if a process such as setting up a knitted fabric that starts a new knitting is required.
しカゝしながら、経糸挿入機構を備える横編機では、レースバーに複数装着される給 糸管から経糸としてそれぞれ供給される編糸を切断して保持する機能は備えられて いない。したがって、ガーメント単位で緯糸を切り離しても、経糸で編成する組織が含 まれている編地では、複数の経糸は繋がっている状態の編地が編成される。後工程 で、編地の切り離しを効率よく行うためには、抜き糸などを用いて編地を編成し、編成 後に抜き糸を編地から引き抜いて、編地を切り離す必要がある。  However, a flat knitting machine equipped with a warp insertion mechanism does not have a function of cutting and holding knitting yarns respectively supplied as warp yarns from a plurality of yarn supply pipes attached to a lace bar. Therefore, even when the wefts are separated in units of garment, a knitted fabric in which a plurality of warp yarns are connected is knitted in a knitted fabric that includes a structure knitted with warp yarns. In order to efficiently detach the knitted fabric in the subsequent process, it is necessary to knitted the knitted fabric using a drawn yarn, etc., and after the knitting, draw the extracted yarn from the knitted fabric to separate the knitted fabric.

Although not shown, the transfer piece 12 is also provided on the knitting needle 7b on the needle bed 6b side, and transfer from the knitting needle 7b side to the knitting needle 7a side is also possible. In addition, although the latch needle is shown as the knitting needles 7a and 7b, a compound needle can also be used. For compound needles, this is done by moving the slider with a slider.
以上で説明している各列の給糸管 3a, 3b, 3c, 3d、針床 6a, 6b、編針 7a, 7b、お よびシンカー 8a, 8bは、総称するときは、給糸管 3、針床 6、編針 7およびシンカー 8 のように、添え字 a, b, c, dなしで示す。  The yarn feeding pipes 3a, 3b, 3c, 3d, needle beds 6a, 6b, knitting needles 7a, 7b, and sinkers 8a, 8b described above are collectively referred to as the yarn feeding pipe 3, needle. Shown without subscripts a, b, c, d, such as floor 6, knitting needle 7 and sinker 8.
経糸挿入機構 2は、たとえば前側である針床 6b側の編針 7bが歯口 5に進出して ヽ る状態で、その先端のフックに経糸 4を掛けるように、スイングおよびラッピングを行う 。従来の経糸挿入機構 2では、図に示す後側の針床 6a上方の位置と、図 6に示す前 側の針床 6bの上方の位置との間で、 2ポジションのスイング動作を行う。本実施形態 の経糸挿入機構 2では、後述するが図 4に示すように、針床 6a側で、さらに歯口 5か ら離れる奥に、 3番目のスイング動作のポジションを設けている。針床 6aでは、ニード ルプレート 6cを押さえる帯金 6d上に、突起 13を立設させる。突起 13の位置は、歯口 5からは離れており、従来からの 2ポジションのスイング動作では経糸を掛けることが できない。経糸挿入機構 2では、各列の給糸管 3a, 3b, 3c, 3dに、突起 13の位置を 越える 3番目のポジションまでのスイング動作を可能にしている。突起 13は、針床 6a の長手方向に沿って、間隔をあけて複数設けられる。給糸管 3が 3番目のポジション までスイング動作を行い、ラッピング動作を組み合わせると、歯口 5と突起 13との間に 経糸 4を掛け渡し、往復する被切断部 14を形成することができる。 The warp insertion mechanism 2 swings and wraps so that, for example, the knitting needle 7b on the side of the needle bed 6b, which is the front side, advances into the tooth opening 5 and hangs the warp 4 on the hook at the tip. The conventional warp insertion mechanism 2 performs a two-position swing operation between a position above the rear needle bed 6a shown in the drawing and a position above the front needle bed 6b shown in FIG. In the warp insertion mechanism 2 of the present embodiment, as will be described later, as shown in FIG. 4, a third swing operation position is provided on the needle bed 6a side and further away from the tooth opening 5. In the needle bed 6a, the protrusion 13 is erected on the band 6d that holds the needle plate 6c. The position of the protrusion 13 is away from the tooth mouth 5, and the conventional two-position swing motion cannot be used to apply the warp. In the warp insertion mechanism 2, each row of yarn supply pipes 3a, 3b, 3c, 3d can swing to the third position beyond the position of the protrusion 13. Projection 13 is needle bed 6a A plurality of them are provided at intervals along the longitudinal direction. When the yarn feeding pipe 3 swings to the third position and is combined with the lapping action, the warp 4 can be passed between the tooth mouth 5 and the projection 13 to form the cut portion 14 that reciprocates.
経糸 4の被切断部 14に対しては、刃 15を作用させて切断を行うことができる。たと えば、刃 15はホルダ 16に設けられ、ホルダ 16を軌道 17に沿って移動可能にしてお く。軌道 17は、針床 6aの長手方向に平行に設ける。ホルダ 16に備えられるローラ 18 a, 18bは、軌道 17を挟むようにして、ホルダ 16を移動可能に支持する。軌道 17は、 針床 6aでキャリッジ 9の走行を案内する軌道 19の端部に設けられる支柱 20によって 支持される。  Cutting can be performed on the portion 14 of the warp 4 by operating the blade 15. For example, the blade 15 is provided in the holder 16 so that the holder 16 can be moved along the track 17. The track 17 is provided parallel to the longitudinal direction of the needle bed 6a. The rollers 18 a and 18 b provided in the holder 16 support the holder 16 so as to be movable so as to sandwich the track 17. The track 17 is supported by a support 20 provided at the end of the track 19 that guides the traveling of the carriage 9 by the needle bed 6a.
なお、経糸係止部としての突起 13は、単一の部品で、ピアノ線を揷通させ、帯金 6d 上に力しめて固定している。帯金 6d上に単一の部品として固定するのではなぐニー ドルプレート 6cから延出させて一体に形成することもできる。また、ニードルプレート 6 c間に収容するスぺーサなどの板状の部材カも延出させて突起 13を形成させることも できる。さらに、経糸係止部は、突起 13以外にも、進退,出没するような部材、または 経糸を把持可能な構成等、種々のものを利用することができる。  The protrusion 13 as the warp locking portion is a single part that is passed through the piano wire and fixed on the band 6d by force. Instead of being fixed as a single part on the strap 6d, it can also be formed integrally with the needle plate 6c. Further, a plate-shaped member such as a spacer accommodated between the needle plates 6c can be extended to form the projections 13. In addition to the protrusions 13, various members such as a member that can be advanced and retracted, or a structure that can hold a warp can be used as the warp locking portion.
図 2は、横編機 1の全体的な構成を簡略ィ匕して正面側カゝら示す。図 1の針床 6bが 前側の針床となり、切断手段となる刃 15、ホルダ 16および軌道 17は、後側の針床 6a に設けられる。針床 6a, 6b間の歯口 5の上方には、糸道レール 21が架設され、キヤリ ッジ 9によって連行されるヤーンフィーダ 22から緯糸となる編糸を供給することができ る。経糸挿入機構 2は、レースバー 23に複数の給糸管 3を装着し、スイング軸 24まわ りの揺動変位によるスイング動作と、スイング軸 24の軸方向への変位によるラッピング 動作とが可能である。キャリッジ 9および経糸挿入機構 2の動作による編地の編成中 、切断手段は、針床 6の長手方向の一端側で待機する。編地の編成が終了すると、 図 1の被切断部 14の形成と、後述するような端糸処理とが行われ、切断手段を移動 させて、刃 15で被切断部 14を切断する。このような経糸 4の処理動作は、コントロー ラ 25による制御下で行われる。なお、糸道レール 21複数設けられ、各糸道レール 21 にはそれぞれ複数のヤーンフィーダ 22を設けることが可能であり、またレースバー 23 も複数設けられるけれども、説明の便宜のため、それぞれ 1つずつで示す。 図 3〜図 7は、図 1の横編機 1で経糸 4を切断して保持する動作を、主要部の側面 断面で示す。 4列の給糸管 3a, 3b, 3c, 3dは、必ずしも全部を使用するとは限らな いけれども、説明の便宜上、全部の位置を示す。なお、経糸挿入機構 2から給糸され る経糸 4を用いる編地の編成は終了し、編地は前側の針床 6bの編針 7bから払い落 とされている状態とする。ただし、払いはいつでも可能である。被切断部 14を形成し て保持して力 切断し、後から払うようにすることもできる。また、編地の編目を、前側 の針床 6bの編針 7bで保持している状態から、後側の針床 6aの編針 7aに目移しした 後、被切断部 14を形成して端糸を保持することもできる。 FIG. 2 shows the overall configuration of the flat knitting machine 1 in a simplified manner and shows the front side cover. The needle bed 6b in FIG. 1 is the front needle bed, and the blade 15, the holder 16, and the track 17 serving as cutting means are provided on the rear needle bed 6a. A yarn path rail 21 is installed above the mouth 5 between the needle beds 6a and 6b, and a knitting yarn serving as a weft can be supplied from a yarn feeder 22 entrained by the carriage 9. The warp insertion mechanism 2 has a plurality of yarn supply pipes 3 attached to the race bar 23, and can perform a swing operation by swinging displacement around the swing shaft 24 and a wrapping operation by displacement of the swing shaft 24 in the axial direction. is there. During the knitting of the knitted fabric by the operation of the carriage 9 and the warp insertion mechanism 2, the cutting means stands by at one end side in the longitudinal direction of the needle bed 6. When the knitting of the knitted fabric is finished, formation of the cut portion 14 in FIG. 1 and end yarn processing as described later are performed, the cutting means is moved, and the cut portion 14 is cut by the blade 15. Such processing operation of the warp 4 is performed under the control of the controller 25. A plurality of yarn path rails 21 are provided, and each yarn path rail 21 can be provided with a plurality of yarn feeders 22 and a plurality of race bars 23 are provided. Shown at a time. FIGS. 3 to 7 show operations of cutting and holding the warp 4 with the flat knitting machine 1 of FIG. The four rows of yarn supply pipes 3a, 3b, 3c, 3d are not necessarily all used, but are shown in their positions for convenience of explanation. The knitting of the knitted fabric using the warp 4 supplied from the warp insertion mechanism 2 is finished, and the knitted fabric is in a state of being wiped off from the knitting needle 7b of the front needle bed 6b. However, payment is possible at any time. It is also possible to form and hold the cut portion 14 and force-cut and then pay later. Further, after the stitch of the knitted fabric is held by the knitting needle 7b of the front needle bed 6b and transferred to the knitting needle 7a of the rear needle bed 6a, the cut portion 14 is formed and the end yarn is formed. It can also be held.
図 3は、給糸管 3が後側の針床 6a上の中間位置 (0)に位置している状態を示す。 突起 13は、中間位置 (0)よりも歯口 5から離れている位置から立設される。たとえば、 給糸管 3aから経糸 4を編地に供給して 、る場合、歯口 5の下方に垂れ下がる編地か らの経糸 4が給糸管 3aに連なる。図 4は、レースバーをスイング動作でさらに振って、 給糸管 3が歯口 5からさらに離れて、後側の針床 6a上方の奥の位置(―)に存在して いる場合を示す。給糸管 3は、突起 13の位置よりも針床 6aの奥まで揺動するので、ラ ッビング動作を組み合わせれば、経糸 4を突起 13に引っ掛けることもできる。これによ つて、図 1の被切断部 14のうちの一方となる方の経糸 4を、歯口 5の下方に垂れ下が る編地の上部と突起 13とに張り渡すことができる。なお、編目の払いが行われていな ければ、編目を保持する編針 7bと突起 13との間に被切断部 14の一方となる経糸 4 を張り渡すことになる。  FIG. 3 shows a state where the yarn feeding pipe 3 is located at the intermediate position (0) on the rear needle bed 6a. The protrusion 13 is erected from a position farther from the tooth opening 5 than the intermediate position (0). For example, when the warp 4 is supplied to the knitted fabric from the yarn supply pipe 3a, the warp 4 from the knitted fabric that hangs down below the mouth 5 is connected to the yarn supply pipe 3a. FIG. 4 shows a case where the lace bar is further swung in a swing motion, and the yarn feeding pipe 3 is further away from the tooth mouth 5 and is present at the back position (−) above the rear needle bed 6a. Since the yarn feeding pipe 3 swings from the position of the protrusion 13 to the back of the needle bed 6a, the warp 4 can be hooked on the protrusion 13 by combining the rubbing operation. Thus, the warp 4 that is one of the cut portions 14 in FIG. 1 can be stretched over the upper portion of the knitted fabric that hangs down below the tooth opening 5 and the projection 13. If the stitch has not been paid, the warp 4 serving as one of the parts to be cut 14 is stretched between the knitting needle 7b holding the stitch and the projection 13.
図 5は、レースバーを図の手前側にラッピングし、給糸管 3から供給する経糸 4が突 起 13よりも手前側になるようにしてから、レースバーを中間位置 (0)にスイングさせて いる状態を示す。キャリッジの通過で、前側の針床 6bからは、編針 7bが歯口 5に進出 する。図 6は、給糸管 3を前側の針床 6b上方の位置(+ )にスイングさせ、経糸 4を編 針 7bの針幹に掛けることが可能になっている状態を示す。図 7は、レースバーを図の 奥側にラッピングし、給糸管 3が中間位置 (0)となるようにスイングさせ、キャリッジを走 行させて、編針 7bを歯口 5から後退させている状態を示す。編地および編針 7bの先 端と突起 13との間に、経糸 4が往復する被切断部 14が形成されている。被切断部 1 4では、図 4で形成される編地力ゝら突起 13までの経糸 4と、図 7で形成される突起 13 力も編針 7bの先端までの経糸 4とは、図 4と図 5との間のラッピング動作で給糸管 3が 変位する距離の範囲内に存在する突起 13の最大間隔だけ、紙面に垂直な方向の 間隔があいている。したがって、図 1のように、刃 15を作用させて切断する場合、図 2 で示すような位置で待機する刃 15に近い側の被切断部 14の経糸 4のみを切断する ことができる。 Fig. 5 wraps the lace bar to the front side of the figure so that the warp 4 supplied from the yarn supply pipe 3 is on the front side of the protrusion 13 and then swings the lace bar to the intermediate position (0). It shows the status. As the carriage passes, the knitting needle 7b advances from the front needle bed 6b into the tooth opening 5. FIG. 6 shows a state in which the yarn feeding pipe 3 can be swung to a position (+) above the front needle bed 6b and the warp 4 can be hung on the needle stem of the knitting needle 7b. In Fig. 7, the lace bar is wrapped to the far side in the figure, the yarn feeding pipe 3 is swung so that it is in the intermediate position (0), the carriage is run, and the knitting needle 7b is retracted from the tooth opening 5. Indicates the state. Between the knitted fabric and the leading end of the knitting needle 7b and the projection 13, a cut portion 14 in which the warp 4 reciprocates is formed. In the to-be-cut part 14, the warp 4 from the knitted fabric force formed in FIG. 4 to the protrusion 13 and the protrusion 13 formed in FIG. The warp 4 to the tip of the knitting needle 7b is the direction perpendicular to the paper surface by the maximum interval of the protrusions 13 that exist within the distance of the displacement of the yarn feeding tube 3 by the lapping operation between FIG. 4 and FIG. There is an interval. Therefore, as shown in FIG. 1, when cutting with the blade 15 acting, it is possible to cut only the warp 4 of the part 14 to be cut on the side close to the blade 15 waiting at the position shown in FIG.
以下、前側の針床 6b上方の位置(+ )へのスイングを、「スイング( + )」と表記する。 また、中間位置 (0)へのスイングを、「スイング (0)」と表記する。後側の針床 6a上方 の奥の位置( )へのスイングを、「スイング(一)」と表記する。  Hereinafter, the swing to the position (+) above the front needle bed 6b is referred to as “swing (+)”. The swing to the intermediate position (0) is expressed as “swing (0)”. The swing to the back position () above the rear needle bed 6a is referred to as “swing (one)”.
図 8および図 9は、図 1の刃 15を備える切断手段としての構成を示す。図 8は正面 から見る構成、図 9は側方から断面を見る構成をそれぞれ示す。ただし、図 9では、ホ ルダ 16を簡略化して示す。ホルダ 16は、ローラ 18a, 18bによって軌道 17を上下で 挟んで支持され、軌道 17側に設けられるワイヤ 26に引っ張られて、軌道 17に沿う移 動を行うことができる。ワイヤ 26の駆動は、軌道 17の一端で行われる。軌道 17に対 するワイヤ 26の相対的な移動は、ワイヤ 26が掛けられて 、るプーリ 27を回転させる。 プーリ 27には、同軸に歯車 28が設けられ、プーリ 27とともに回転する。歯車 28は径 が大きい歯車 29と嚙合する。歯車 29は、径が小さい歯車 30と嚙合する。歯車 28, 2 9, 30は、同一のモジュールであり、相互に嚙み合うことが可能である。歯車 30の径 は、歯車 28の径より小さいので、歯車 30は歯車 28よりも高速で回転する。歯車 30の 回転軸には、丸刃状の刃 15が設けられ、歯車 30とともに回転する。  8 and 9 show a configuration as a cutting means including the blade 15 of FIG. Fig. 8 shows the configuration viewed from the front, and Fig. 9 shows the configuration viewed from the side. However, in FIG. 9, the holder 16 is shown in a simplified manner. The holder 16 is supported by the rollers 18a and 18b with the track 17 sandwiched between the upper and lower sides, and can be moved along the track 17 by being pulled by the wire 26 provided on the track 17 side. The driving of the wire 26 is performed at one end of the track 17. The relative movement of the wire 26 with respect to the track 17 causes the wire 26 to hang and cause the pulley 27 to rotate. The pulley 27 is provided with a gear 28 coaxially and rotates together with the pulley 27. The gear 28 meshes with the gear 29 having a large diameter. The gear 29 meshes with the gear 30 having a small diameter. The gears 28, 29, 30 are the same module and can be interdigitated. Since the diameter of the gear 30 is smaller than the diameter of the gear 28, the gear 30 rotates at a higher speed than the gear 28. A rotating blade of the gear 30 is provided with a round blade 15 and rotates together with the gear 30.
なお、刃 15は回転する丸刃ではなくてもよい。静止した刃、往復動する刃、または 超音波振動する刃などを用いることができる。熱線またはレーザ光などで焼き切ること もできる。刃 15のように、専用の軌道 17を、ワイヤ 26で外部から牽引して走行させる ばかりではなぐホルダ 16に駆動源を搭載して、自走させることも可能である。また、 軌道 17に代えて、糸道レール 21などを利用することもできる。さらに、刃をキャリッジ 9に搭載しておいたり、キャリッジ 9が選択的に連行するようにして、切断が必要となる 時に作用させて、被切断部 14を切断するようにしてもよい。  The blade 15 need not be a rotating round blade. A stationary blade, a reciprocating blade, or an ultrasonically vibrating blade can be used. It can also be burned out with heat rays or laser light. Like the blade 15, it is possible to mount the drive source on the holder 16, which is not only to pull the dedicated track 17 from the outside with the wire 26, and to make it self-run. Further, in place of the track 17, a yarn path rail 21 or the like can be used. Further, a blade may be mounted on the carriage 9 or the carriage 9 may be selectively entrained to act when the cutting is necessary to cut the portion 14 to be cut.
図 10は、案内部材 31およびばね 32の形状を示す。経糸 4の切断は、回転する刃 1 5を図 1のように被切断部 14に移動させ、待機位置に近い側の経糸 4を切断する。被 切断部 14には待機位置力 離れる側の経糸 4も存在して 、るけれども、近 、側の経 糸 4を切断して経糸 4の張力が減少した後では、刃 15に待機位置力も離れる側の経 糸 4が掛カもないようにするために、案内部材 31が設けられる。案内部材 31は、ホル ダ 16に対して相対的に揺動変位可能であり、ばね 32で刃 15から遠ざ力る側に付勢 されている。ばね 32の付勢力は、被切断部 14で経糸 4が往復している状態での張力 よりも弱くしておく。したがって、被切断部 14の経糸 4の最初の切断の際には、経糸 4 の張力がばね 32の付勢力よりも勝り、経糸 4は案内部材 31を押し退けて、経糸 4は 刃 15に掛かり、切断される。被切断部 14で往復する経糸 4の一方である待機位置に 近い側の経糸 4が切断されると、経糸 4の張力は低下してほとんど消失し、案内部材 31はばね 32の付勢で元の状態に戻る。次に刃 15が被切断部 14の経糸 4の残部で ある待機位置力も遠い側の経糸 4に達しても、経糸 4の張力が弱くなつて、ばね 32の 付勢力の方が大きくなるので、経糸 4は案内部材 31を押し退けることができず、案内 部材 31が壁となり、経糸 4は刃 15に掛からなくなる。 FIG. 10 shows the shapes of the guide member 31 and the spring 32. The warp 4 is cut by moving the rotating blade 15 to the cut portion 14 as shown in FIG. 1 and cutting the warp 4 on the side close to the standby position. Covered The cutting portion 14 also has the warp 4 on the side away from the standby position force. However, after cutting the warp 4 on the near side and the tension of the warp 4 is reduced, the side on which the standby position force is also released from the blade 15 is separated. A guide member 31 is provided to prevent the warp yarn 4 from being hooked. The guide member 31 can be oscillated and displaced relative to the holder 16 and is urged by a spring 32 toward the side away from the blade 15. The urging force of the spring 32 is made weaker than the tension when the warp 4 is reciprocating at the cut portion 14. Therefore, when the warp 4 of the cut portion 14 is first cut, the tension of the warp 4 exceeds the urging force of the spring 32, the warp 4 pushes the guide member 31 away, and the warp 4 hits the blade 15. Disconnected. When the warp 4 on the side close to the standby position, which is one of the warps 4 reciprocating at the part 14 to be cut, is cut, the tension of the warp 4 decreases and almost disappears, and the guide member 31 is restored to its original position by the bias of the spring 32. Return to the state. Next, even when the blade 15 reaches the warp 4 on the far side, which is the remaining part of the warp 4 of the part 14 to be cut, the tension of the warp 4 becomes weak and the biasing force of the spring 32 becomes larger. The warp 4 cannot push away the guide member 31, the guide member 31 becomes a wall, and the warp 4 does not catch on the blade 15.
なお、ばね 32で付勢される案内部材 31は、必ずしも必要とは限らない。ただし、ヮ ィャ 26を高速で駆動する高速移動の場合、または被切断部 14で往復する経糸 4の 間隔が狭い場合には有効である。  Note that the guide member 31 biased by the spring 32 is not always necessary. However, this is effective in the case of high-speed movement in which the carrier 26 is driven at high speed, or when the interval between the warps 4 reciprocating at the cut portion 14 is narrow.
図 11A〜図 11Cは、図 3〜図 7で被切断部 14を形成する動作と、図 7以降で、経 糸 4を編針 7bに掛ける動作とを示す。図 11Aに示すように、突起 13は、後側の針床 6a上で歯口 5から離れた位置に、たとえば編針 6aの 4本に 1つの割合で、間隔をあけ て設けられる。編地の編成を終了した後、給糸管 3を、図 3に示す中立位置 (0)から 図 4に示す奥の位置(―)までのスイング(―)を行って往路の被切断部 14aとなる経 糸を形成する。次に、図 5に示すようなラッピング動作とスイング動作とで突起 13の背 後に回る経糸 4aを供給する。さらに、図 5に示すような、奥の位置(一)から中立位置 (0)までのスイング (0)の動作で、復路の被切断部 14bとなる経糸を形成する。復路 の被切断部 14bが形成されると、給糸管 3は図 6と図 7との間のスイング動作、および 編針へのラッピング動作、ならびに編針の編成動作で、被切断部 14の経糸 4の切断 後も端糸の先端を保持可能にすることができる。  11A to 11C show the operation of forming the cut portion 14 in FIGS. 3 to 7 and the operation of hooking the warp 4 on the knitting needle 7b in FIG. 7 and thereafter. As shown in FIG. 11A, the protrusions 13 are provided on the rear needle bed 6a at a position away from the tooth opening 5, for example, at a rate of one for every four knitting needles 6a. After the knitting of the knitted fabric is finished, the yarn feeding pipe 3 is swung (-) from the neutral position (0) shown in FIG. 3 to the back position (-) shown in FIG. A warp is formed. Next, the warp 4a that rotates behind the protrusion 13 is supplied by a lapping operation and a swing operation as shown in FIG. Further, as shown in FIG. 5, the warp to be cut 14b in the return path is formed by the swing (0) operation from the back position (one) to the neutral position (0). When the cut portion 14b on the return path is formed, the yarn feeding pipe 3 is swung between FIG. 6 and FIG. 7, wrapping to the knitting needle, and knitting operation of the knitting needle. Even after cutting, the end of the end yarn can be held.
図 11Bに示すように、端糸を保持するための保持部 40は、復路の被切断部 14bが 形成される位置の近傍で、前側の針床 6bの編針 7bを使用して、たとえば複数回、 8 の字状に経糸 4を係止させて編成する。たとえば、 3本の編針 A, B, Cが存在すると、 Bの編針を 1本あけた編針 A, C間に形成される。 As shown in FIG. 11B, the holding portion 40 for holding the end yarn is formed by the cut portion 14b on the return path. In the vicinity of the position to be formed, the knitting needles 7b of the front needle bed 6b are used to knitting the warp yarns 4 in the shape of 8, for example, a plurality of times. For example, if there are three knitting needles A, B, and C, they are formed between the knitting needles A and C with one B knitting needle opened.
たとえば前側の針床 6bに設けられるキャリッジ 9に、編針 7bを駆動するカムが 3シス テム搭載されている場合に、中央を通常の編成または目移し用のカムとし、両側を経 糸用のカムとする。保持部 40を編成する第 1の動作では、 A, B, Cの編針には、編 目が掛カつておらず、キャリッジ 9を右方に走行させ、 3番目のカムシステム S3で編針 Aを歯口に進出させる。次に、第 2の動作では、レースバーのスイング(+ )後のラッピ ングで、給糸管 3を編針 Aの左方から編針 Cの右方まで移動させ、スイング (0)で編 針 Aの針幹に経糸 4を掛ける。第 3の動作では、キャリッジを右方力も左方に走行させ て、 1番目のカムシステム S1で編針 Aを引き込み、 3番目のカムシステム S3で編針 C を歯口に進出させる。第 4の動作では、レースバーのスイング(+ )後のラッピングで、 給糸管 3を編針 Cの右方から編針 Aの左方に移動させ、スイング (0)で編針 Cの針幹 に経糸 4を掛ける。  For example, when three systems of cams that drive the knitting needle 7b are mounted on the carriage 9 provided on the front needle bed 6b, the center is a normal knitting or transfer cam, and both sides are cams for warp And In the first operation of knitting the holding section 40, the stitches of the knitting needles A, B, and C are not hooked, the carriage 9 is moved to the right, and the knitting needle A is moved by the third cam system S3. Advance to the mouth. Next, in the second operation, the yarn feeding pipe 3 is moved from the left side of the knitting needle A to the right side of the knitting needle C by wrapping after the swing (+) of the lace bar, and the knitting needle A is moved by the swing (0). Hang the warp 4 on the needle stem. In the third operation, the carriage moves to the left also in the right direction, and the knitting needle A is retracted by the first cam system S1, and the knitting needle C is advanced to the tooth opening by the third cam system S3.

図 11Cは、前側の針床 6bで 1本あけた編針 A, Cに対して、 A→C→A→C→Aの 順で経糸 4を掛け、 8の字に経糸 4を編針 A, Cに掛けて編成する保持部 40を形成し た状態を示す。なお、保持部 40と同様な機能は、 8の字状ではなぐ単に巻き付ける だけでも実現することができる。また、針本数および間隔はこれに限らない。 1本の編 針に対して、複数回巻き付けて保持することもできる。  In Fig. 11C, knitting needles A and C, one of which is opened at the front needle bed 6b, are multiplied by warp 4 in the order of A → C → A → C → A, and warp 4 is applied to the figure 8 with knitting needles A, C. A state is shown in which a holding part 40 is formed which is knitted by hanging. Note that the same function as that of the holding unit 40 can be realized by simply winding it in the shape of a figure 8. Further, the number of needles and the interval are not limited to this. A single knitting needle can be wound and held multiple times.
図 11Cでは、被切断部 14を形成した後で、図 11Bに示す保持部 40を形成し、図 2 に示す刃 15の待機位置に近い側の復路となる被切断部 14bの経糸を切断する。往 路となる被切断部 14aに連なる編地 41がたとえばガーメント単位で編成を終了し、編 針カゝら払われていれば、復路となる被切断部 14bの切断で、突起 13の背後に回る経 糸 4aと往路となる被切断部 14aとからなる被切断部 14の残部は、編地 41に引かれ て歯口 5の下方に落下する。復路となる被切断部 14bで切断された給糸管 3側の経 糸 4は、保持部 40で編針 A, Cに保持される。  In FIG. 11C, after the cut portion 14 is formed, the holding portion 40 shown in FIG. 11B is formed, and the warp of the cut portion 14b serving as a return path on the side close to the standby position of the blade 15 shown in FIG. 2 is cut. . If the knitted fabric 41 connected to the cut-out portion 14a that is the forward path has been knitted in units of garment, for example, if the knitting needles have been removed, the cut-off portion 14b that will be the return path is cut behind the projection 13 The remaining portion of the cut portion 14, which is composed of the rotating warp 4 a and the cut portion 14 a that is the outward path, is pulled by the knitted fabric 41 and falls below the tooth opening 5. The warp 4 on the yarn feeding pipe 3 side cut by the cut portion 14b that becomes the return path is held by the holding needles 40 on the knitting needles A and C.
編地 41に近い、往路となる被切断部 14a側を切断し、復路となる被切断部 14b側 を残すこともできる。ただし、突起 13の背後に回る経糸 4aと復路となる被切断部 14b が保持部 40の前に残ってしまう。復路となる被切断部 14b側を切断すれば、編地 41 の落下で、切断後の長い端糸が編地 41とともに落下し、保持部 40側には短い端糸 しか残らず、邪魔にならな 、ようにすることができる。  It is also possible to cut the cut portion 14a side that is the forward path, which is close to the knitted fabric 41, and leave the cut portion 14b side that is the return path. However, the warp 4a that rotates behind the protrusion 13 and the cut portion 14b that becomes the return path remain in front of the holding portion 40. If the cut portion 14b side that is the return path is cut, the knitted fabric 41 falls, and the long end yarn after cutting drops together with the knitted fabric 41, leaving only a short end yarn on the holding portion 40 side. You can do that.
図 12Aおよび図 12Bは、往復する被切断部 14を 1つの突起 13を使用して形成す る例を示す。図 12Aは、往路となる被切断部 14aと復路となる被切断部 14bとの間隔 が狭い場合を示す。図 12Bは、復路となる被切断部 14bを、突起 13と編針 7bとの距 離が大きくなるように形成し、往路となる被切断部 14aとの間隔を大きくしている状態 を示す。図 12Aのように間隔が狭くても、低速にしたりして刃 15の移動の精度を高め れば、一方の被切断部 14のみを切断することができる。 12A and 12B show that a reciprocated part 14 is formed by using one protrusion 13. An example is shown. FIG. 12A shows a case where the distance between the cut portion 14a serving as the forward path and the cut portion 14b serving as the return path is narrow. FIG. 12B shows a state in which the cut portion 14b serving as the return path is formed so that the distance between the protrusion 13 and the knitting needle 7b is increased, and the distance between the cut portion 14a serving as the forward path is increased. Even if the interval is narrow as shown in FIG. 12A, if the movement accuracy of the blade 15 is increased by reducing the speed, it is possible to cut only one of the parts 14 to be cut.
経糸 4を切断した後で、連続して次のガーメントの編地を編成する場合は、保持部 4 0に続いて、編出し編成を行う。保持部 40は、編出しの捨て編み部分に編み込まれ、 続いて実際に次のガーメントの編地になる部分が編成される。  When the knitted fabric of the next garment is continuously knitted after the warp 4 is cut, the set-up knitting is performed following the holding unit 40. The holding unit 40 is knitted into the set-up discarded knitted portion, and then the portion that actually becomes the knitted fabric of the next garment is knitted.
以上のように、経糸 4の挿入が可能な横編機 1で、経糸挿入機構 2による針床 6の 長手方向に垂直なスイング動作と、長手方向に平行なラッピング動作とで、経糸 4に 針床 6の長手方向と間隔をあけて往復して交差する被切断部 14を形成する。被切断 部 14を形成した経糸 4を複数の編針 7に掛けて保持する。保持した被切断部 14に対 し、針床 6の長手方向に移動する刃 15を作用させて経糸 4を切断する。被切断部 14 の切断箇所力 経糸挿入機構 2側に存在する経糸 4は、 1または複数の編針 7に掛 けられて保持される。次に経糸 4を使用する編成は、先端を保持する状態で開始す ることがでさる。  As described above, in the flat knitting machine 1 in which the warp 4 can be inserted, the needle is attached to the warp 4 by the swing operation perpendicular to the longitudinal direction of the needle bed 6 by the warp insertion mechanism 2 and the lapping operation parallel to the longitudinal direction. A cut portion 14 is formed that reciprocates and intersects with the longitudinal direction of the floor 6 at an interval. The warp 4 having the cut portion 14 is hung on a plurality of knitting needles 7 and held. The warp 4 is cut by causing the blade 15 moving in the longitudinal direction of the needle bed 6 to act on the held part 14 to be cut. The cutting part force of the part 14 to be cut The warp 4 existing on the side of the warp insertion mechanism 2 is hooked and held on one or a plurality of knitting needles 7. Next, knitting using warp 4 can be started with the tip held.
以上のような、被切断部 14および保持部 40の形成は、ガーメント毎に切断'保持す る場合に行うことができる。所望の編地のガーメント単位での編成が終了すると、緯糸 による 1コース以上の編成での捨て編みおよび解れ止めの処理を行った後、編地の 編目を保持している編針に対して給糸なしでニット動作を行わせて、編針から編目を 払う。ただし、編成中と同様に、卷下げローラなどの編地引き下げ装置で編地を挟ん だままとして、編地の歯口での引き下げを継続する。編針力も編目を払うことによって 、給糸管 3からの経糸 4は、歯口 5の下方で、かつ卷下げローラの上方に位置する編 地に渡る状態で、垂れ下がる。図 11Aに示すようなレースバーのスイング(一)→ラッ ビング (振り)→スイング (0)によって、経糸 4を突起 13に巻き付けて被切断部 14を形 成する。経糸 4には、編地から突起 13へ延びる往路の被切断部 14aと、突起 13から 給糸管 3へ延びる復路の被切断部 14bとが形成される。以下、保持部 40を形成し、 復路の被切断部 14bを刃 15で切断する。往路の被切断部 14aに連なる編地は、卷 下げローラで排出される。編地力も往路の被切断部 14aおよび突起 13の背後に回る 経糸 4aと、復路の被切断部 14bで切断された経糸 4の残りは、歯口 5から落下する。 復路の被切断部 14bでの切断箇所よりも保持部 40側の経糸 4と、保持部 40から給 糸管 3に渡る経糸 4とは残る。この状態から、編み出しを経て、次のガーメントの編地 を編み出すことができる。 The formation of the cut portion 14 and the holding portion 40 as described above can be performed when cutting and holding each garment. When knitting of the desired knitted fabric in units of garment is completed, the yarn is fed to the knitting needles that hold the stitches of the knitted fabric after performing the knitting and unfastening processing in one or more courses with weft. Let the knitting operation be performed without using the knitting needle. However, as in the knitting, the knitted fabric is kept sandwiched by the knitted fabric lowering device such as a lowering roller, and the knitted fabric is continuously pulled down at the mouth. When the knitting needle force is also applied to the stitches, the warp yarn 4 from the yarn feeding pipe 3 hangs down in a state where it crosses over the knitted fabric located below the tooth opening 5 and above the lowering roller. As shown in FIG. 11A, the warp 4 is wound around the protrusion 13 to form the cut portion 14 by swinging the lace bar (one) → rubbing (swing) → swing (0). The warp 4 is formed with a forward cut portion 14 a extending from the knitted fabric to the protrusion 13 and a return cut portion 14 b extending from the protrusion 13 to the yarn supplying pipe 3. Thereafter, the holding portion 40 is formed, and the cut portion 14b on the return path is cut with the blade 15. The knitted fabric connected to the forward cut portion 14a is It is discharged by the lowering roller. The knitted fabric force also rotates behind the cut portion 14a and the projection 13 in the forward path, and the remainder of the warp 4a cut by the cut portion 14b in the return path falls from the mouth 5. The warp 4 on the side of the holding part 40 from the cut part in the cut part 14b on the return path and the warp 4 extending from the holding part 40 to the yarn supply pipe 3 remain. From this state, after knitting, the knitted fabric of the next garment can be knitted.
すなわち、往復する被切断部 14を形成する経糸 4には張力が掛カつている。被切 断部 14で往復する経糸 4の一方を切断すれば、他方の経糸 4の張力は低下する。 一方の経糸 4の切断後で張力が低下した他方の経糸 4に対しては、刃 15での切断を 防ぐので、被切断部 14を往復して形成する経糸 4の一方のみを切断し、他方は切断 しないようにすることができる。往復する被切断部 14の両方を切断すると、短い端糸 が分離して、糸屑となって編地に付着するようなおそれがある。し力しながら、本実施 形態においては被切断部 14の残部は切断しないので、糸屑の発生を防ぐことができ る。  That is, tension is applied to the warp 4 that forms the reciprocated part 14 to be cut. If one of the warps 4 reciprocating at the cut portion 14 is cut, the tension of the other warp 4 is lowered. For the other warp 4 whose tension has dropped after cutting one warp 4, the blade 15 is prevented from being cut, so only one of the warps 4 formed by reciprocating the cut portion 14 is cut, and the other Can be cut off. If both the reciprocating parts 14 to be reciprocated are cut, short end yarns may be separated and become yarn waste and adhere to the knitted fabric. However, in this embodiment, since the remaining portion of the cut portion 14 is not cut, the generation of yarn waste can be prevented.
また、ガーメント単位の編地の編成中でも、経糸 4を使用して編成する領域がコース 方向に離れている場合、領域間に渡り糸が生じる。経糸 4を使用する 1つの領域の編 成が終了すると、編目の払いを除いて、ガーメント間と同様な端糸処理を行うようにす れば、渡り糸を切断することができる。渡り糸が残存していると、編地編成後の後工程 で除去しなければならなくなるので、後工程で必要となる手間を削減することができる 本発明は、その精神または主要な特徴力 逸脱することなぐ他のいろいろな形態 で実施できる。したがって、前述の実施形態はあらゆる点で単なる例示に過ぎず、本 発明の範囲は特許請求の範囲に示すものであって、明細書本文には何ら拘束され ない。さらに、特許請求の範囲に属する変形や変更は全て本発明の範囲内のもので ある。  In addition, even when knitting a garment unit knitted fabric, if the area to be knitted using the warp 4 is separated in the course direction, a crossover yarn is generated between the areas. When the knitting of one region using warp 4 is completed, the transition yarn can be cut by performing the same end yarn treatment as that between the garments, except for the knitting of the stitches. If the crossover yarn remains, it must be removed in the subsequent process after the knitting of the knitted fabric, so that the labor required in the subsequent process can be reduced. It can be implemented in various other forms. Therefore, the above-described embodiment is merely an example in all respects, and the scope of the present invention is shown in the claims, and is not restricted by the text of the specification. Further, all modifications and changes belonging to the scope of claims are within the scope of the present invention.
産業上の利用可能性 Industrial applicability
本発明によれば、経糸挿入機構による針床の長手方向に垂直なスイング動作と、 長手方向に平行なラッピング動作とで、経糸に編地とは異なる被切断部を形成し、被 切断部を形成した経糸を編針に掛けて保持することができる。経糸を保持した後で、 被切断部に刃を作用させて経糸を切断すると、切断箇所カゝら経糸挿入機構側に存 在する経糸は、編針に掛けられて保持されるので、切断後の端糸を適切に保持する ことができる。次に経糸を使用する編成は、先端を保持する状態で開始することがで きる。 According to the present invention, a to-be-cut portion different from the knitted fabric is formed on the warp yarn by a swing operation perpendicular to the longitudinal direction of the needle bed by the warp insertion mechanism and a wrapping operation parallel to the longitudinal direction. The formed warp can be hung on a knitting needle and held. After holding the warp, When the warp is cut by applying a blade to the part to be cut, the warp existing on the side of the warp insertion mechanism is held on the knitting needle, so that the end yarn after cutting is appropriately held. be able to. The knitting using the warp can then be started with the tip held.
また本発明によれば、経糸挿入機構のスイング動作を、歯口から離れた位置に立 設する経糸係止部を越えるところまで可能にしておき、経糸を経糸係止部に掛けて 被切断部を形成して、経糸につ ヽての切断および保持を行うことができる。  Further, according to the present invention, the swing operation of the warp insertion mechanism can be performed up to a place beyond the warp locking part standing at a position away from the tooth opening, and the warp is hung on the warp locking part to be cut. Can be cut and retained for the warp.
また本発明によれば、複数のガーメントの編地を連続して編成する際に、被切断部 をガーメント間に形成して、編地を切り離し、糸端を保持することができる。  Further, according to the present invention, when a plurality of garment knitted fabrics are continuously knitted, the cut portion can be formed between the garments, the knitted fabric can be cut off, and the yarn ends can be held.
また本発明によれば、被切断部を形成する前に編地の編成と緯糸の切断とが終了 していれば、編目を払うことによって、被切断部の経糸には編地を落下させる張力が 掛かる。被切断部の経糸を切断しても、経糸挿入機構側の経糸は編針で保持され、 切断された経糸の被切断部の残部からは張力が低減され、編地に引っ張られて、編 地とともに落下する。  Further, according to the present invention, if the knitting of the knitted fabric and the weft cutting are completed before the cut portion is formed, the tension that drops the knitted fabric on the warp yarn of the cut portion by removing the stitches. It takes. Even when the warp at the part to be cut is cut, the warp on the side of the warp insertion mechanism is held by the knitting needle, the tension is reduced from the remaining part of the cut part of the cut warp, and pulled to the knitted fabric, together with the knitted fabric Fall.
また本発明によれば、往復するように形成される被切断部の経糸には張力が掛か つているけれども、被切断部の一方を切断すれば、他方の経糸の張力は低下する。 張力が低下した他方の経糸に対しては、刃での切断を防ぐので、被切断部を往復し て形成する経糸の一方のみを切断し、他方は切断しないようにすることができる。往 復する被切断部の両方を切断すると、短い端糸が分離して、糸屑となる。一方を切断 して他方を切断しないことで、糸屑の発生を防ぐことができる。  In addition, according to the present invention, tension is applied to the warp of the part to be cut formed so as to reciprocate, but if one of the parts to be cut is cut, the tension of the other warp is reduced. Since the other warp with reduced tension is prevented from being cut by the blade, it is possible to cut only one of the warps formed by reciprocating the part to be cut and not cut the other. When both of the parts to be cut back and forth are cut, the short end yarns are separated and become yarn waste. Generation of lint can be prevented by cutting one side and not the other.
さらに本発明によれば、編地の編成後に、経糸挿入機構による針床の長手方向に 垂直な 3ポジションのスイング動作と、針床の長手方向に平行なラッピング動作とで、 歯ロカゝら離れた位置に立設される突起に経糸を掛けて被切断部を形成し、被切断 部を形成した経糸を編針に掛けて保持することができる。経糸を編針に掛けてで保 持した後で、被切断部の経糸を、切断手段によって切断することができる。切断箇所 から経糸挿入機構側に存在する経糸は、編針に掛けられて保持されるので、切断後 の端糸を適切に保持することができる。次に経糸を使用する編成は、先端を保持す る状態で開始することができる。  Furthermore, according to the present invention, after the knitted fabric is knitted, the three-position swing operation perpendicular to the longitudinal direction of the needle bed by the warp insertion mechanism and the lapping operation parallel to the longitudinal direction of the needle bed are separated from the tooth loci. It is possible to form a cut portion by hooking a warp on the protrusion standing upright, and hold the warp yarn having the cut portion on a knitting needle. After the warp is held on the knitting needle, the warp at the part to be cut can be cut by the cutting means. Since the warp yarn present on the warp insertion mechanism side from the cut portion is hung on the knitting needle and held, the end yarn after cutting can be appropriately held. The knitting using the warp can then be started with the tip held.
