To provide a method for manufacturing a toothed belt without deviation of a core wire and deviation of a reinforcing member stuck on the surface of a tooth part when an unvulcanized rubber is pressed into along a gap between an outer mold and a core mold.
In the method for manufacturing the toothed belt wherein the tooth parts and channel parts are alternately arranged at specified intervals along the longitudinal direction, and the core wire is buried in the back part, and the reinforcing member is stuck on the surface of the tooth part, the method for manufacturing the toothed belt comprises as follows. The cylindrical reinforcing member 23 is mounted on the outer periphery of the core mold 3 being a toothed shape molding mold, and the core wire 25 is spun on the reinforcing member 23. The core mold 3 is placed in the outer mold 2, and a preheating ring 28 is installed on the end face 20 of the core mold 3. While the core mold 3 is heated, the unvulcanized rubber is pressed into a cavity 10 between the outer mold 2 and the core mold 3, and is vulcanized by heating. A belt sleeve 29 is taken out from the core mold 3 taken out from the outer mold 2.
