以下にこの発明の紡糸用スリーブＳの製造方法を実施するための最良の形態として実施例について詳しく説明する。   Hereinafter, examples will be described in detail as the best mode for carrying out the method for manufacturing the spinning sleeve S of the present invention.

図１はこの発明の実施例１の製造方法によって成形された紡糸用スリーブＳの一部断面斜視図、図２は前記紡糸用スリーブＳの断面図、図３は前記紡糸用スリーブＳの製造工程図を示している。   1 is a partial cross-sectional perspective view of a spinning sleeve S formed by the manufacturing method of Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view of the spinning sleeve S, and FIG. 3 is a manufacturing process of the spinning sleeve S. The figure is shown.

（この紡糸用スリーブＳついて）
この紡糸用スリーブＳは、図１や図２に示すように、内外の帆布１，２と、これら帆布１，２で挟み込まれた心線３及びゴム部４ａ（後述するゴム板４から形成されたもの）から成るものであり、全体の厚みが１．４ｍｍの円筒状に成形されている。 (About this spinning sleeve S)
As shown in FIGS. 1 and 2, the spinning sleeve S includes inner and outer canvases 1 and 2, and a core wire 3 and a rubber portion 4a (a rubber plate 4 described later) sandwiched between the canvases 1 and 2. And is formed into a cylindrical shape having a total thickness of 1.4 mm.

ここで、帆布１、２は共にナイロン６６（商標）により構成されているが、帆布１が単独で構成されているのに対して、帆布２は片面にＥＰＤＭ製のゴム板４を貼り合わされたもの（以下、トッピング帆布という）としてある。また、心線３は、アラミドで構成したものである。   Here, the canvases 1 and 2 are both made of nylon 66 (trademark), whereas the canvas 1 is made up of a single piece, whereas the canvas 2 has a rubber plate 4 made of EPDM bonded to one side. As a thing (hereinafter referred to as a topping canvas). The core wire 3 is made of aramid.

（この紡糸用スリーブＳの製造方法について）
この紡糸用スリーブＳは、以下の工程を経て製造される。
(1) 第1工程
円筒状のモールド9０に帆布1を被せる（図３の（Ａ））。 (About the manufacturing method of this spinning sleeve S)
The spinning sleeve S is manufactured through the following steps.
(1) First step The canvas 1 is placed on the cylindrical mold 90 ((A) in FIG. 3).

(2) 第２工程
前記帆布１上に心線３を螺旋状に巻き付ける（図３の（Ｂ））。 (2) 2nd process The core wire 3 is wound around the canvas 1 in a spiral shape ((B) of FIG. 3).

(3) 第３工程
ゴム板４が貼り合わされた帆布２中のゴム板４側を心線３と対向させる態様で被せる（図３の（Ｃ））。 (3) Third process
The rubber plate 4 in the canvas 2 to which the rubber plate 4 is bonded is covered with the core wire 3 so as to face the core wire 3 ((C) in FIG. 3).

ところで、背景技術の欄に記載した紡糸スリーブＳは、帆布−心線−ゴム−帆布という４層構造になっているが、この中で最も重量が大きいのはゴムであり、ゴムを如何に薄くできるかが軽量化のポイントとなる。しかしながら、ゴムをあまり薄くすると、製造時に皺が入ったりゴム同志が付着したりするトラブルがあるため、ゴムの種類にもよるが厚さを１ｍｍ以下にはできない。   By the way, the spinning sleeve S described in the section of the background art has a four-layer structure of canvas-core wire-rubber-canvas. Among these, rubber is the heaviest, and how thin the rubber is. The point of weight reduction is whether it can be done. However, if the rubber is made too thin, there is a problem that wrinkles and rubbers adhere to each other at the time of manufacture, so the thickness cannot be reduced to 1 mm or less depending on the type of rubber.

そこで、この発明の実施例では、ゴムの厚みを０．３５ｍｍ程度まで薄くすることが可能である、帆布２にゴムを予め貼り合わせたトッピング帆布を採用した。   Therefore, in the embodiment of the present invention, a topping canvas in which rubber is bonded to the canvas 2 in advance, which can reduce the thickness of the rubber to about 0.35 mm, is employed.

なお、トッピング帆布は、上下貼り合わせ帆布の場合にはゴム厚は０．２５ｍｍまで薄くできるが、片側貼り合わせの場合には心線を埋設するためにゴム厚は０．３５ｍｍ以上必要である。   The topping canvas can have a rubber thickness as thin as 0.25 mm in the case of a vertically bonded canvas, but in the case of one-side bonded, the rubber thickness needs to be 0.35 mm or more in order to embed the core wire.

(4) 第4工程
帆布２の上から図３の（Ｄ）に示すようにバッグゴム８を外挿しその後、上記第３工程でできた積層体を加硫缶９１に投入し、所定の温度及び圧力で加熱・加圧して加硫成型する。 (4) Fourth step The bag rubber 8 is extrapolated from the top of the canvas 2 as shown in FIG. 3 (D), and then the laminate formed in the third step is put into the vulcanizing can 91 at a predetermined temperature. And vulcanize molding by heating and pressurizing with pressure.

(5) 第５工程
加硫缶９１から加硫成形物（帆布1、ゴム板４が貼り合わされた帆布２、及び心線３が加硫一体化された物）を取り出して脱型し、所定の幅に裁断すると、紡糸用スリーブＳは完成する。 (5) Fifth step The vulcanized molded product (the canvas 1, the canvas 2 to which the rubber plate 4 is bonded, and the core 3 are vulcanized and integrated) is taken out from the vulcanizing can 91, demolded, and predetermined. The sleeve S for spinning is completed.

（この紡糸用スリーブＳの製造方法の優れた点等について）
背景技術の欄に記載した紡糸用スリーブが四層構造であるのに対して、この実施例の紡糸用スリーブＳは帆布１、片面にゴム板４を貼り合わされた帆布２、心線３の三層構造であり、よって、この製造方法によると製造工程が簡略化できる。 (About excellent points of the manufacturing method of the spinning sleeve S)
The spinning sleeve described in the Background Art section has a four-layer structure, whereas the spinning sleeve S of this embodiment has a canvas 1, a canvas 2 with a rubber plate 4 bonded to one side, and a cord 3. Thus, the manufacturing process can be simplified according to this manufacturing method.

また、この紡糸用スリーブＳの製造方法では、ゴムの厚みを０．３５ｍｍ程度まで薄くすることが可能であり、全体の厚みが薄く且つ重量が軽い紡糸用スリーブを提供できる。   Further, in the method for manufacturing the spinning sleeve S, the thickness of the rubber can be reduced to about 0.35 mm, and a spinning sleeve having a small overall thickness and a light weight can be provided.

そして、この製造方法で形成された紡糸用スリーブＳは、全体の厚みが薄く（折り曲げやすく）且つ重量が軽いので、作業時の取り扱いが容易であり、特に巻かれたガラス繊維を抜き取る作業が容易になる。   The spinning sleeve S formed by this manufacturing method has a thin overall thickness (easy to bend) and is light in weight, so that it is easy to handle at the time of operation, and particularly easy to extract the wound glass fiber. become.

（この紡糸用スリーブＳの製造方法の他の態様について）
上記紡糸用スリーブＳの製造方法は以下の如く変えることができる。 (Other aspects of the method for producing the spinning sleeve S)
The method for producing the spinning sleeve S can be changed as follows.

上記実施例では、帆布２側のみをトッピング帆布としたが、これに限定されることなく、帆布１側のみをトッピング帆布としてもよく、また、帆布１、２の両方をトッピング帆布としてもよい。この場合、ゴムの厚みを０．２５ｍｍ程度まで薄くしたトッピング帆布を使用できる。   In the above embodiment, only the canvas 2 side is used as the topping canvas, but not limited to this, only the canvas 1 side may be used as the topping canvas, and both the canvases 1 and 2 may be used as the topping canvas. In this case, a topping canvas having a rubber thickness reduced to about 0.25 mm can be used.

ここで、帆布１、２は、ナイロン、綿、ポリエステル繊維のいずれか又はこれらを組み合わせたもの、帆布１又は／及び２に貼り合わされルゴムは、ＥＰＤＭ、ＨＮＢＲ、ＦＫＭゴムのいずれかのもの、心線３は、アラミド、ガラス、ＰＢＯ、ポリアリレート繊維のいずれかで構成されたコードとすることができる。   Here, canvases 1 and 2 are nylon, cotton, polyester fibers or a combination thereof, and rubber bonded to canvas 1 or / and 2 is one of EPDM, HNBR, FKM rubber, heart The wire 3 can be a cord composed of any one of aramid, glass, PBO, and polyarylate fiber.
