ようにしたことを特徴とする。In order to solve the above-mentioned problems, the present invention employs the following technical means. In the belt manufacturing method of the present invention, a long tubular wound body is disposed outside a vulcanizing rubber cylinder located outside a molded body provided on a mold, and when the molded body is heated and pressed, By supplying the heating and pressurizing fluid from one end side of the tubular wound body, the heating and pressurizing fluid expands and presses the rubber cylinder for vulcanization, thereby giving a time difference at the time of molding. Is characterized by securing time to escape.

お、従来は必ずしも押し出されるとは限らなかった。In this belt manufacturing method, when the molded body is heated and pressurized, a heated and pressurized fluid is supplied from one end side of the tubular wound body (the outer peripheral shape of the cross section is not necessarily circular). Since the heating and pressurizing fluid expands and presses the rubber cylinder for vulcanization, there is a time difference at the time of molding, and the time difference ensures the time for residual air to escape. The air in the space, the air in the space between the cords, and the air between the rubber sheet layers are gradually pushed out of the space. Conventionally, it was not always extruded.

る時間を確保するようにしてもよい。In the case of a toothed belt, for example, a molded body is a combination of a mold covered with a cylindrical tooth cloth, a core wire wound thereon, and a rubber sheet wound thereon. A combination of a rubber sheet wound around a mold, a core wire, and a rubber sheet further wound (in some cases, the mold may be first covered with a cylindrical cloth, and may be finally covered with a cylindrical cloth. In the case of a V-ribbed belt, it refers to a combination body in which a mold is covered with a cylindrical cloth, followed by winding an adhesive rubber sheet, then a core wire, and further winding an adhesive rubber sheet and a ribbed rubber sheet. By disposing a long tubular wound body inside the mold and supplying a heating pressurized fluid from one end side of the tubular wound body, heating from the inside of the mold also has a time difference during molding. The time for the residual air to escape may be secured by the time difference.

Can be kicked out.

Above the vulcanizer 9, an inlet and an outlet 10 for heated and pressurized steam are provided. The heat-resistant tube 5 is spirally wound outside the rubber cylinder 4 and inside the vulcanizing device 9, and its final end, that is, the lower end is closed. In addition, below the vulcanizing device 9, a valve without drain is arranged.

The steam that has flowed into the heat-resistant tube 5 through the inlet 10 of the vulcanizing device 9 reaches the lower end of the tube and fills a tube path that is spirally wound upward from the lower end. I will do it.

With this seal, the heated and pressurized steam does not enter the inside of the vulcanizing apparatus 9 and the outside of the heat-resistant rubber tube 5, and can be sufficiently filled while expanding to the upper part of the rubber cylinder 4.

The air between the outside of the rubber sheet 8 and the inside of the rubber cylinder 4 is sequentially pushed out to another space through a gap between the upper part of the mold 2 and the projection 14 of the vulcanizing device 9.

As the steam is filled, the molded body 3 is heated and pressurized with a time lag from the lower part to the upper part. In addition,
Due to the expansion of the lower portion of the heating tube 5, the rubber cylinder 4 is sufficiently heated and pressurized, and the slide portion 12 connected to the rubber cylinder 4 moves inward.

うにすることができる。As described above, the steam is introduced into the heat-resistant tube 5 to press the heat-resistant rubber cylinder 4 to be molded. However, since a time lag occurs before the molding is completed, the air existing in the space between the tooth grooves of the molded body is formed. The air in the space between the core wires, the air in the rubber sheet layer, and the like are gradually pushed out from the space, and the molding is performed as sufficiently as possible so that no air bubbles are contained.

A metal tube may be used as the heat-resistant tube 5. The end of the heat-resistant tube 5 is open and is heated backward from the steam inlet. In order to support the heat-resistant tube 5 from the inside, a cylindrical body 21 and a disk-shaped reinforcing plate 22 are provided.

効に活用することができる。Further, since steam flows into and out of the heat-resistant and pressure-resistant tube 5, the steam does not come into direct contact with the molded body 3, and steam leakage to the molded portion occurs from outside the mold and from inside the mold. In addition, there is no generation of product defects due to steam leakage. Therefore, industrial waste is no longer produced, and valuable earth resources can be used effectively.

Glass wool whose outside is covered with a thin metal film can be used as the heat insulating material. With this configuration, heat leakage to the outside of the vulcanizing apparatus can be suppressed by the heat insulating material, and heat inside the vulcanizing apparatus, which becomes high during molding, can be used efficiently.
