Description

本発明は、ティーバッグ、だしの抽出バッグ等の抽出バッグの製造に使用される抽出バッグ用シートの製造方法及び製造装置に関する。   The present invention relates to an extraction bag sheet manufacturing method and a manufacturing apparatus used for manufacturing extraction bags such as tea bags and dashi extraction bags.

紅茶、緑茶、ハーブ等のティーバッグ、煮干し、鰹節等の出汁の抽出バッグとして、不織布、紗等の通水濾過性シートを平袋状、四面体状等の袋体に形成すると共に、その内部に茶葉等の抽出材料を充填し、その外表面にタグ付吊し糸を取り付けたものが使用されている（特許文献１）。   As a tea bag for tea, green tea, herbs, etc., as a bag for extracting soup stock such as boiled and dried bonito, a water-permeable filterable sheet such as non-woven fabric and rice cake is formed into a flat bag, tetrahedron bag, etc. A material in which an extraction material such as tea leaves is filled inside and a hanging thread with a tag is attached to the outer surface is used (Patent Document 1).

抽出バッグの製造に使用する抽出バッグ用シートは、製造する抽出バッグの形状や、吊し糸の長さ、タグの形状などにより種々の態様があるが、従来、吊し糸の一端が接着されているタグを、帯状の通水濾過性シートの長手方向に所定間隔で一列に配置したものが使用されている。このような抽出バッグ用シートの製造方法としては、長尺な糸材にタグを所定間隔で取り付け、そのタグ付の長尺な糸材を、長尺な通水濾過性シートの幅方向に引き出し、タグと糸材をそれぞれ通水濾過性シートと接着し、糸材を後続の糸材から切断する方法がある（特許文献２）。   The extraction bag sheet used for manufacturing the extraction bag has various modes depending on the shape of the extraction bag to be manufactured, the length of the hanging thread, the shape of the tag, and the like. Conventionally, one end of the hanging thread is bonded. The tags are arranged in a line at predetermined intervals in the longitudinal direction of the belt-shaped water-permeable filterable sheet. As a method for manufacturing such a sheet for an extraction bag, a tag is attached to a long thread material at a predetermined interval, and the long thread material with the tag is pulled out in the width direction of the long water-permeable filterable sheet. There is a method in which a tag and a thread material are respectively bonded to a water-permeable filterable sheet, and the thread material is cut from the subsequent thread material (Patent Document 2).

しかしながら、この方法によれば、タグと吊し糸の接着を、通水濾過性シートを連続的に搬送しながら行うことはできず、生産速度を十分に高めることができない。   However, according to this method, the tag and the hanging thread cannot be adhered while the water-permeable filterable sheet is continuously conveyed, and the production speed cannot be sufficiently increased.

これに対し、回転担持体の周面に所定間隔でタグを配置し、その上に長尺な糸材を所定パターンで張って各タグと糸材を接着し、そのタグと糸材の上に通水濾過性シートを供給し、回転担持体上でタグと糸材とを通水濾過性シートと接着する方法が知られている。これにより、図８に示す抽出バッグ用シート１Ｘのように、長尺の通水濾過性シート２の長手方向にタグ３が所定間隔で配列すると共に、長尺の糸材４ｂが所定パターンに配置され、各タグ３と接着している抽出バッグ用シートを得ることができる（特許文献３、特許文献４）。なお、図中、破線で区切った領域が抽出バッグ１個分の領域に相当する。   On the other hand, tags are arranged at a predetermined interval on the circumferential surface of the rotation carrier, and a long thread material is stretched in a predetermined pattern on the tag to bond each tag to the thread material. A method is known in which a water-permeable filterable sheet is supplied and a tag and a thread material are bonded to the water-filterable sheet on a rotating carrier. Thus, as in the extraction bag sheet 1X shown in FIG. 8, the tags 3 are arranged at predetermined intervals in the longitudinal direction of the long water-permeable filterable sheet 2, and the long yarn materials 4b are arranged in a predetermined pattern. Thus, an extraction bag sheet bonded to each tag 3 can be obtained (Patent Document 3 and Patent Document 4). In addition, the area | region divided with the broken line corresponds to the area | region for one extraction bag in the figure.

この方法によれば、通水濾過性シート２を連続的に搬送しながら抽出バッグ用シート１Ｘを製造することができるので、特許文献２の方法に比して抽出バッグ用シートの生産速度を高めることができる。   According to this method, since the extraction bag sheet 1X can be manufactured while continuously transporting the water-permeable filterable sheet 2, the production speed of the extraction bag sheet is increased as compared with the method of Patent Document 2. be able to.

しかしながら、抽出バッグ用シート１Ｘ上で糸材４ｂが連続しているため、抽出バッグ用シート１Ｘから個々の抽出バッグを製袋する際のシール部位（破線部分）に糸材４ｂが存在することにより、シール装置に負担がかかり、またシール装置が糸材４ｂを噛むおそれもある。   However, since the thread material 4b is continuous on the extraction bag sheet 1X, the thread material 4b is present at the seal portion (dashed line portion) when making individual extraction bags from the extraction bag sheet 1X. There is a risk that the sealing device is burdened and the sealing device may bite the thread material 4b.

本発明は、抽出バッグ用シートから個々の抽出バッグを製袋する際のシール部位に糸材が無く、かつ高い生産速度で製造することができる抽出バッグ用シートの製造方法及び製造装置を提供することを目的とする。   The present invention provides a manufacturing method and a manufacturing apparatus for an extraction bag sheet that can be manufactured at a high production rate without a thread material at a seal portion when individual extraction bags are manufactured from the extraction bag sheet. For the purpose.

本発明者は、回転担持体上に所定間隔でタグを配置し、長尺の糸材を用いて抽出バッグ用シートを製造するにあたり、回転担持体上で長尺の糸材を個々の抽出バッグ分の長さの吊し糸に切断し、回転担持体上にタグと吊し糸の断続的パターンを形成すると、抽出バッグ用シートを高い生産速度で製造することができ、かつ抽出バッグ用シートから個々の抽出バッグを製袋する際のシール工程で糸材が支障をきたすことを防止できることを見いだした。   The present inventor arranges tags at predetermined intervals on a rotating carrier and manufactures an extraction bag sheet using a long yarn material. When the cut string is cut into the length of the hanging thread and the intermittent pattern of the tag and the hanging thread is formed on the rotating carrier, the sheet for the extraction bag can be manufactured at a high production rate, and the sheet for the extraction bag From the above, it has been found that the thread material can be prevented from being hindered in the sealing process when making individual extraction bags.

即ち、本発明は、吊し糸と接着したタグが、通水濾過性シートの長手方向に所定間隔で配列している抽出バッグ用シートの製造方法であって、次の工程
（１）回転担持体上で、タグに吊し糸が固定されている、タグと吊し糸の断続的パターンを形成する工程、
（２）断続的パターンに形成したタグと吊し糸を、通水濾過性シートと接着する工程
を有する抽出バッグ用シートの製造方法を提供する。 That is, the present invention is a method for manufacturing a sheet for an extraction bag in which tags bonded to a hanging thread are arranged at predetermined intervals in the longitudinal direction of the water-permeable filterable sheet. Forming an intermittent pattern of the tag and the hanging thread, wherein the hanging thread is fixed to the tag on the body,
(2) Provided is a method for producing a sheet for an extraction bag having a step of adhering a tag and a hanging thread formed in an intermittent pattern to a water-permeable filterable sheet.

また、本発明は、上述の抽出バッグ用シートの製造方法を実施する装置として、吊し糸と接着したタグが、通水濾過性シートの長手方向に所定間隔で配列している抽出バッグ用シートの製造装置であって、
タグを所定間隔で保持する手段、及びタグ上に吊し糸が固定されている、タグと吊し糸の断続的パターンを形成する手段を備えた回転担持体、並びに
断続的パターンに形成したタグと吊し糸を通水濾過性シートと接着する接着手段を備えた製造装置を提供する。 In addition, the present invention provides an apparatus for carrying out the above-described method for producing an extraction bag sheet, wherein the tags bonded to the hanging thread are arranged at predetermined intervals in the longitudinal direction of the water-permeable filterable sheet.

本発明によれば、回転担持体上で、長尺の糸材を個々の抽出バッグ分の長さの吊し糸に切断した吊し糸の断続的パターンを、回転担持体の動きを止めることなく連続的に形成し、さらにこの断続的パターンを通水濾過性シートに、その通水濾過性シートの搬送を止めることなく連続的に接着することができる。したがって、抽出バッグ用シートを高い生産速度で製造することが可能となる。   According to the present invention, an intermittent pattern of a hanging thread obtained by cutting a long thread material into a hanging thread having a length corresponding to each extraction bag is stopped on the rotating carrier. The continuous pattern can be formed continuously without being stopped, and the intermittent pattern can be continuously adhered to the water-filterable sheet without stopping the conveyance of the water-filterable sheet. Therefore, the extraction bag sheet can be manufactured at a high production rate.

また、本発明により得られる抽出バッグ用シートは、吊し糸が断続的パターンであるため、抽出バッグ用シートから個々の抽出バッグを製袋する際のシール部位に、吊し糸が存在しないように製袋することができる。したがって、吊し糸によりシール工程に支障がきたされることが防止される。   In addition, the extraction bag sheet obtained by the present invention has an intermittent pattern of the hanging thread, so that the hanging thread does not exist in the seal portion when each extraction bag is made from the extraction bag sheet. Can be made into bags. Accordingly, it is possible to prevent the sealing process from being hindered by the hanging thread.

A third ultrasonic welding device 42 to be bonded and a fourth ultrasonic welding device 43 to temporarily bond the central portion of the hanging thread 4 to the water-permeable filter sheet 2 at the position P4 are provided.

このうち、第２の超音波溶着装置４１は、前述の第１の超音波溶着装置得４０と同様に回転担持体１０表面のタグ保持プレート１１を超音波溶着時の受台とし、第３の超音波溶着装置４２と第４の超音波溶着装置４３は、それぞれ受台４２ｂ、受台４３ｂを備えている。また、第２の超音波溶着装置４１は、カム機構により、超音波接着時に回転担持体１０の回転速度に合わせて図２の矢印ｂのように移動し、第３の超音波溶着装置４２と第４の超音波溶着装置４３は図４の矢印ｃ、矢印ｄのように通水濾過性シート２の搬送速度に合わせて移動し、それぞれ超音波溶着時に回転担持体１０の回転や通水濾過性シート２の搬送系の動きが止まらないようにしている。   Among these, the second ultrasonic welding apparatus 41 uses the tag holding plate 11 on the surface of the rotary carrier 10 as a receiving base during ultrasonic welding, as in the first ultrasonic welding apparatus 40 described above, and the third ultrasonic welding apparatus 41 The ultrasonic welding device 42 and the fourth ultrasonic welding device 43 include a receiving table 42b and a receiving table 43b, respectively. Further, the second ultrasonic welding device 41 is moved by the cam mechanism as indicated by an arrow b in FIG. 2 in accordance with the rotational speed of the rotary carrier 10 during ultrasonic bonding, and the third ultrasonic welding device 42 The fourth ultrasonic welding device 43 moves in accordance with the conveyance speed of the water filterable sheet 2 as indicated by arrows c and d in FIG. The movement of the conveyance system of the adhesive sheet 2 is prevented from stopping.

また、回転担持体１０の直下から第４の超音波溶着装置４３の設置位置にかけて、矢印ｎのように通水濾過性シート２の幅方向に吊し糸４を吸引する吸引手段１７が設けられている。これにより吊し糸４は、幅方向に伸びた状態で整列し、通水濾過性シート２に接着される。   Further, a suction means 17 is provided for sucking the hanging thread 4 in the width direction of the water-permeable filter sheet 2 as indicated by an arrow n from directly below the rotary carrier 10 to the installation position of the fourth ultrasonic welding device 43. ing. Thereby, the hanging thread 4 is aligned in a state of extending in the width direction, and is adhered to the water-permeable filter sheet 2.

なお、本発明においては、タグ３と吊し糸４を通水濾過性シート２と接着する接着手段として、超音波溶着装置４１、４２、４３に代えて熱溶着装置を設けてもよい。   In the present invention, a heat welding device may be provided in place of the ultrasonic welding devices 41, 42, and 43 as the bonding means for bonding the tag 3 and the hanging thread 4 to the water filterable sheet 2.

この製造装置１００Ａにおいて、抽出バッグ用シート１Ａは、（１）回転担持体１０上でタグ３と吊し糸４の断続的パターンを形成する工程と、（２）断続的パターンに形成したタグ３と吊し糸４を、通水濾過性シート２と接着する工程とから、次のように製造される。   In this manufacturing apparatus 100A, the extraction bag sheet 1A includes (1) a step of forming an intermittent pattern of the tag 3 and the hanging thread 4 on the rotating carrier 10, and (2) a tag 3 formed in the intermittent pattern. And the step of adhering the hanging thread 4 to the water-permeable filterable sheet 2 are manufactured as follows.

即ち、（１）の断続的パターンの形成工程では、まず、糸材巻取ロール２２から糸材４ｂを引き出し、その糸材４ｂを、糸折返ローラー２６を介して回転担持体１０に供給する。糸材４ｂは、タグ保持プレート１１のタグ保持面から突出しているピン１２に掛かり、回転担持体１０の矢印方向の回転により、回転担持体１０の周方向に張られる。   That is, in the intermittent pattern forming step (1), first, the yarn material 4 b is pulled out from the yarn material winding roll 22, and the yarn material 4 b is supplied to the rotary carrier 10 via the yarn folding roller 26. The thread material 4 b is caught on the pin 12 protruding from the tag holding surface of the tag holding plate 11, and is stretched in the circumferential direction of the rotation carrier 10 by the rotation of the rotation carrier 10 in the arrow direction.

また、タグ巻取ロール２１からタグ用テープ３ｂを引き出し、図２に示すように、タグカット供給装置３０により回転担持体１０のタグ保持プレート１１にタグ３を所定間隔で供給する。回転担持体１０のタグ保持プレート１１は、タグカット供給装置３０から供給されたタグ３を、直ちにタグ保持プレート１１に吸引保持する。   Further, the tag tape 3b is pulled out from the tag winding roll 21, and the tag 3 is supplied to the tag holding plate 11 of the rotation carrier 10 at a predetermined interval by the tag cut supply device 30 as shown in FIG. The tag holding plate 11 of the rotary carrier 10 sucks and holds the tag 3 supplied from the tag cut supply device 30 immediately on the tag holding plate 11.

次に、プッシャー１３を、隣り合うタグ３の間に押し出す。これにより、プッシャー１３の溝１４に掛かった糸材４ｂは、隣り合うタグ３の少なくとも一方上を通り、それらのタグ３間に導かれたパターンとなる。そして、図３に示すように、隣り合うタグ３間の糸材４ｂの長さが、抽出バッグ１個分の吊し糸４の長さとなるようにプッシャー１３が押し出されたところで、第１の超音波溶着装置４０で、タグ３と糸材４ｂを接着部位Ｐ１で接着し、回転刃１５が、糸材４ｂを、隣り合うタグ３のいずれか一方に寄せた位置Ｑで切断し、プッシャー１３が、切断した糸材４ｂ（吊し糸４）を引き続き同方向に押し出す。また、このとき切断した糸材４ｂを、回転担持体１０の軸方向（ｍ方向）に吸引し、同方向に伸ばして整列させる。   Next, the pusher 13 is pushed out between the adjacent tags 3. As a result, the thread material 4 b that hangs on the groove 14 of the pusher 13 passes through at least one of the adjacent tags 3 and becomes a pattern guided between the tags 3. Then, as shown in FIG. 3, when the pusher 13 is pushed out so that the length of the thread material 4b between the adjacent tags 3 becomes the length of the hanging thread 4 for one extraction bag, the first With the ultrasonic welding device 40, the tag 3 and the thread material 4b are bonded at the bonding site P1, and the rotary blade 15 cuts the thread material 4b at one of the adjacent tags 3 at a position Q. However, the cut thread material 4b (hanging thread 4) is continuously pushed out in the same direction. Further, the thread material 4b cut at this time is sucked in the axial direction (m direction) of the rotary carrier 10, and is stretched and aligned in the same direction.

こうして、回転担持体１０上にタグ３と吊し糸４の断続的パターンが形成される。   Thus, an intermittent pattern of the tag 3 and the hanging thread 4 is formed on the rotation carrier 10.

回転担持体１０上にタグ３と吊し糸４の断続的パターンを形成した後は、（２）の断続的パターンに形成したタグ３と吊し糸４の、通水濾過性シート２との接着工程を、特許文献３や特許文献４に記載されているような公知の手法により、回転担持体１０上に通水濾過性シート２を供給し、回転担持体１０上でタグ３と吊し糸４を通水濾過性シート２と接着することにより行ってもよいが、その場合には、回転担持体１０上に超音波溶着装置等の接着装置を集中させなくてならないので、接着装置の設計の自由度が制約される。   After the intermittent pattern of the tag 3 and the hanging thread 4 is formed on the rotating carrier 10, the water filterable sheet 2 of the tag 3 and the hanging thread 4 formed in the intermittent pattern of (2). In the bonding process, the water-permeable filterable sheet 2 is supplied onto the rotation carrier 10 by a known method as described in Patent Document 3 or Patent Document 4, and the tag 3 is suspended from the rotation carrier 10. The yarn 4 may be bonded to the water-filterable sheet 2, but in that case, an adhesive device such as an ultrasonic welding device must be concentrated on the rotary carrier 10. Design freedom is limited.

そこで、工程（２）を、(2a)回転担持体１０に形成したタグ３と吊し糸４の断続的パターンを通水濾過性シート２に移す工程と、(2b)工程(2a)以降にタグ３と吊し糸４をそれぞれ通水濾過性シート２と接着する工程とから行うことが好ましく、特に工程(2b)は、タグ３と吊し糸４の断続的パターンを通水濾過性シート２に移すときにタグ３を通水濾過性シート２と接着し、その後に吊し糸４と通水濾過性シート２とを接着することが好ましい。これによりタグ３と吊し糸４を通水濾過性シート２と接着する際の接着装置の自由度を高め、抽出バッグ用シートの製造装置１００Ａ全体としての保守等も容易となる。   Therefore, the process (2) is performed by (2a) transferring the intermittent pattern of the tag 3 and the hanging thread 4 formed on the rotating carrier 10 to the water filterable sheet 2, and (2b) after the process (2a). It is preferable to carry out from the step of adhering the tag 3 and the hanging thread 4 to the water-permeable filterable sheet 2, respectively. It is preferable to adhere the tag 3 to the water-filterable sheet 2 when moving to 2, and then bond the hanging thread 4 and the water-filterable sheet 2 to each other. As a result, the degree of freedom of the bonding apparatus when bonding the tag 3 and the hanging thread 4 to the water-filterable sheet 2 is increased, and maintenance of the extraction bag sheet manufacturing apparatus 100A as a whole is facilitated.

図１の製造装置１００Ａは、上述の工程(2a)、(2b)によりタグ３と吊し糸４を通水濾過性シート２と接着する工程を行うものであり、タグ３と吊し糸４の断続的パターンが形成されている回転担持体１０の最下部で、回転担持体１０はタグ３の吸引を切り、タグ３と吊し糸４を、回転担持体１０からその直下に搬送されている通水濾過性シート２に移す。   The manufacturing apparatus 100A of FIG. 1 performs the process of adhering the tag 3 and the hanging thread 4 to the water filterable sheet 2 by the above-described steps (2a) and (2b). At the bottom of the rotary carrier 10 where the intermittent pattern is formed, the rotary carrier 10 cuts off the suction of the tag 3, and the tag 3 and the hanging thread 4 are conveyed from the rotary carrier 10 directly below it. Transfer to the water-permeable filterable sheet 2.

また、回転担持体１０の最下部で、第２の超音波溶着装置４１でタグ３と通水濾過性シート２とを接着部位Ｐ2で仮接着する。   In addition, the tag 3 and the water-permeable filter sheet 2 are temporarily bonded to each other at the bonding portion P2 by the second ultrasonic welding device 41 at the lowermost portion of the rotary carrier 10.

その後、矢印方向ｎに吊し糸４を吸引して糸を整列させ、第３の超音波溶着装置４２でタグ３と吊し糸４とを接着部位Ｐ3で強接着すると共に、第４の超音波溶着装置４３で吊し糸４と通水濾過性シート２とを接着部位Ｐ4で仮接着する。   Thereafter, the hanging thread 4 is sucked in the direction of the arrow n to align the threads, the tag 3 and the hanging thread 4 are strongly bonded at the bonding site P3 by the third ultrasonic welding device 42, and the fourth super The hanging thread 4 and the water-permeable filterable sheet 2 are temporarily bonded by the sonic welding device 43 at the bonding site P4.

こうして、吊し糸４と接着したタグ３が、通水濾過性シート２上で通水濾過性シート２の長手方向に所定間隔で配列している抽出バッグ用シート１Ａを得る。   In this way, the extraction bag sheet 1A in which the tag 3 adhered to the hanging thread 4 is arranged on the water-permeable filter sheet 2 at a predetermined interval in the longitudinal direction of the water-filterable sheet 2 is obtained.

得られた抽出バッグ用シート１Ａは、図５に示すように抽出バッグ用シート巻取ロール２４に巻取る。抽出バッグ用シート巻取ロール２４に巻き取られた抽出バッグ用シート１Ａは、矩形あるいはピラミッド型の抽出バッグを製造する従前の製袋装置で使用することができ、特に、抽出バッグ用シート１Ａから個々の抽出バッグを製造する際のシール部位（破線）に吊し糸４が存在しないため、製袋時のシールを円滑に行うことが可能となる。   The obtained extraction bag sheet 1A is wound around an extraction bag sheet winding roll 24 as shown in FIG. The extraction bag sheet 1A wound around the extraction bag sheet winding roll 24 can be used in a conventional bag making apparatus for manufacturing a rectangular or pyramid type extraction bag, and in particular, from the extraction bag sheet 1A. Since the hanging thread 4 does not exist at the seal portion (broken line) when manufacturing each extraction bag, it is possible to smoothly perform the seal at the time of bag making.

本発明は、回転担持体上でタグと吊し糸の断続的パターンを形成する種々の態様を包含する。   The present invention includes various embodiments for forming an intermittent pattern of a tag and a hanging thread on a rotating carrier.

例えば、図６に示す抽出バッグ用シートの製造装置１００Ｂのように、第１の回転担持体１０ａを用いて、図１に示した装置と同様にして、通水濾過性シート２にタグ３と吊し糸４の断続的パターンを形成する。ただし、各パターンのピッチを倍に広げる。そして、引き続き、第２の回転担持体１０ｂを用いて、通水濾過性シート２にタグ３と吊し糸４の断続的パターンを形成する。   For example, like the extraction bag sheet manufacturing apparatus 100B shown in FIG. 6, the first rotation carrier 10a is used in the same manner as the apparatus shown in FIG. An intermittent pattern of the hanging thread 4 is formed. However, the pitch of each pattern is doubled. Subsequently, the intermittent pattern of the tag 3 and the hanging thread 4 is formed on the water-permeable filterable sheet 2 by using the second rotation carrier 10b.

この場合、図７の抽出バッグ用シート１Ｂに示すように、第１の回転担持体１０ａによるタグ３と吊し糸４のパターンと、第２の回転担持体１０ｂによるタグ３と吊し糸４のパターンのトータルのピッチが揃うようにする。   In this case, as shown in the extraction bag sheet 1B in FIG. 7, the pattern of the tag 3 and the hanging thread 4 by the first rotation carrier 10a, and the tag 3 and the hanging thread 4 by the second rotation carrier 10b. So that the total pitch of the pattern is aligned.

また、抽出バッグ用シートを巻き取ったロールがコーン形状とならないようにして、ロールの取扱性を向上させるため、通水濾過性シート２におけるタグ３の配列を、通水濾過性シート２の片側縁部でなく、両側縁部に形成することが好ましい。そこで、図７に示すように、第１の回転担持体１０ａによるタグ３と吊し糸４のパターンと、第２の回転担持体１０ｂによるタグ３と吊し糸４のパターンを逆向きにすることが好ましい。   Moreover, in order not to make the roll which wound the sheet | seat for extraction bags into a cone shape, and to improve the handleability of a roll, the arrangement | sequence of the tag 3 in the water-permeable filterable sheet 2 is made into the one side of the water-permeable filterable sheet 2. It is preferable to form on both side edges instead of the edges. Therefore, as shown in FIG. 7, the pattern of the tag 3 and the hanging thread 4 by the first rotation carrier 10a and the pattern of the tag 3 and the hanging thread 4 by the second rotation carrier 10b are reversed. It is preferable.

また、上述の製造装置１００Ａにおいて、隣り合うタグ３の間に糸材４ｂを導く糸材回旋手段、及び、隣り合うタグ３の間で切断した糸材４ｂを略直線状に伸ばす吊し糸の整列手段としては、プッシャー１３に代えて、回転担持体１０の周方向に張った糸材４ｂを、ピン１２と反対側から引っ掛け、隣り合うタグ３の間に引き出す手段を設けてもよい。   Further, in the manufacturing apparatus 100A described above, the thread material rotating means for guiding the thread material 4b between the adjacent tags 3 and the hanging thread for extending the thread material 4b cut between the adjacent tags 3 substantially linearly. As the aligning means, instead of the pusher 13, a means for hooking the thread material 4b stretched in the circumferential direction of the rotary carrier 10 from the side opposite to the pin 12 and pulling it out between the adjacent tags 3 may be provided.

回転担持体１０上に断続的パターンに形成したタグ３と吊し糸４を通水濾過性シート２に移す工程で、通水濾過性シート２の背面から吸引することにより、回転担持体１０の直下以外の部位に通水濾過性シート２を搬送し、タグ３と吊し糸４を通水濾過性シート２に移してもよい。   In the step of passing the tag 3 and the hanging thread 4 formed in an intermittent pattern on the rotary carrier 10 to the water filterable sheet 2, the suction of the rotary carrier 10 by sucking from the back surface of the water filterable sheet 2 is achieved. The water-permeable filterable sheet 2 may be transported to a part other than directly below, and the tag 3 and the hanging thread 4 may be transferred to the water-filterable sheet 2.

タグ３と吊し糸４を、回転担持体１０から通水濾過性シート２に移した後、糸を整列させるために、吸引手段１７に代えて、矢印ｎ方向に送風する送風手段を設けてもよい。   After moving the tag 3 and the hanging thread 4 from the rotary carrier 10 to the water-permeable filterable sheet 2, in order to align the threads, air blowing means for blowing air in the direction of arrow n is provided instead of the suction means 17. Also good.
