〔産業上の利用分野〕
この発明は、グラスファイバ等の巻取りに使用されるフ
ォーミングチューブの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a forming tube used for winding glass fiber or the like.

。[Prior Art] Generally, a glass fiber wound in a forming tube is put into a drying oven and subjected to a drying process. In order to avoid adhesion of the part of the glass fiber that comes into contact with the forming tube during drying, a forming tube having a release agent layer on the surface is used as the forming tube.

チューブを槽内に充填した離型剤浴中に浸漬し、浴中か

ら知られている。As a method for manufacturing a forming tube having a mold release agent layer, a tube is formed by a tube manufacturing device, the tube is immersed in a mold release agent bath filled in a tank, and after being taken out from the bath, it is heated and cured. This method has been known for a long time.

方法であるため、フォーミングチューブの長さが槽の大
きさに制約を受け、長いチューブを形成することができ
ず、またチューブの余分な部分に離型剤が付着するため
、離型剤のロスが多いなどの不都合がある。By the way, in the above manufacturing method, the mold release agent layer is formed after the forming tube is manufactured, so the manufacturing process is very time-consuming.Moreover, the mold release agent layer is formed by dipping, which makes it difficult to form the forming tube. The length is limited by the size of the tank, making it impossible to form a long tube, and since the release agent adheres to the excess portion of the tube, there are disadvantages such as a large loss of release agent.
この発明は、上記の不都合を解消し、離型剤層を有する
フォーミングチューブをきわめて能率よく製造し得るよ
うにした製造方法を提供することを目的としている。An object of the present invention is to provide a manufacturing method that eliminates the above-mentioned disadvantages and allows forming tubes having a mold release agent layer to be manufactured extremely efficiently.

成を採用したのである。In order to achieve the above object, in the present invention, a plurality of ribbon-like liner papers are wound around the outer circumference of the mandrel in a spiral manner with the intrusion position relative to the mandrel shifted in the axial direction, so that at least the side edge of the outermost layer of liner paper is Forming a cylinder of several plies with overlapping parts, the cylinder is moved in the axial direction by contact with an endless belt that is inclined with respect to the central axis of the mandrel and moves in one direction, and the axis of the cylinder is In the transfer path of the liner paper that moves toward the outer periphery of the mandrel due to the direction movement, an adhesive layer is formed on the back side of the remaining liner paper except for the innermost layer paper, and an adhesive layer is formed on the surface of the outermost liner paper. A molding agent layer is applied, and the cylinder made of each liner paper is adhered to the inner cylinder by the adhesive layer, and the overlap part of the outermost layer is also adhered. A structure in which the adhesive layer and the release agent layer were cured by heating was adopted.

ことができる。As mentioned above, the liner paper on which the mold release agent layer has been formed is spirally wound around the outside of the mandrel to form a cylinder, and the cylinder is heated to harden the mold release agent layer. The release agent layer can be formed simultaneously with the production of the forming tube.
以下、この発明の実施例を添付図面に基づいて説明する

形成される。Each of the endless belts 4 is inclined in the same direction as the direction in which the second liner paper 3 is wound around the outer periphery of the mandrel 1, and is moved in the direction of the arrow by a drive device (not shown). As the endless belt 4 moves, the two-ply cylinder A provided on the outside of the mandrel 1 comes into contact with the belt 4 and is conveyed in the axial direction. By this movement of the cylinder A, the first liner paper 2 and the second liner paper 3 are drawn toward the mandrel 1, and the cylinder A is sequentially formed.

ー移動方向に順に設けられている。On the other hand, on the transfer path of the second liner paper 3 to the mandrel 1, an adhesive coating device 20 and a release agent coating device 30 are provided in order in the liner movement direction.
ここで、接着剤塗布装置２０は、第２図に示すように、

紙３の裏面に塗布している。Here, the adhesive application device 20, as shown in FIG.
The lower part of the outer periphery of the original roll 22 is immersed in the adhesive layer filled in the tank 21, and the adhesive layer adhering to the outer periphery of the original roll 22 is transferred to the transfer roll 23, and then on the back side of the second liner paper 3. It is being applied.
上記接着剤の塗布によって、第１ライナー紙２から成る
内筒ａと第２ライナー紙３から成る外筒すが互に接着さ

し拡げて均一な厚みの離型剤層６を形成している。The release agent application device 30 causes a release agent such as silicone to flow out in a linear manner onto the surface of the second liner paper 3 from a nozzle 31, and is applied in a linear manner by a film thickness adjustment roll 32 that is in contact with the surface of the second liner paper 3. The release agent is spread over the entire width of the second liner paper 3 to form a release agent layer 6 having a uniform thickness.

離型剤は確保される。Since the mold release agent is liquid, it permeates into the second liner paper 3. Therefore, although some of the mold release agent on the surface of the outer cylinder is removed when it comes into contact with the belt 4, a predetermined amount of mold release agent is maintained on the outer cylinder.

ングチューブが形成される。A heating furnace 40 is provided on the transfer path of the cylindrical body A that is moved in the axial direction of the mandrel 1 by the movement of the belt 4, and as the cylindrical body A moves inside the heating furnace 40,
The mold release agent layer 6 and the adhesive layer 8 are cured, and as shown in FIGS. 3 and 4, the second liner paper 30 overlap portion 7 is bonded to each other, forming the mold release agent layer 6 on the surface. A tube is formed.

Since the axial feed of the cylinder A is reduced, the several sheets of liner paper may be fed toward the outside of the cylinder formed outside the mandrel on the front side of the endless belt 4.
