To provide a transmission belt manufacturing method for simplifying the joining work in the cog ridge parts of a sheet for a compressed rubber while reducing the defective percent of the joining work to manufacture a low cost cogged belt.
Reinforcing cloth 6 is held between a mold 1 alternately having ridge-like parts 4 and grove-like parts 5 and the pinion roll 7 meshed with the ridge-like parts 4 and grove-like parts 5 to be shaped while synchronously rotating the mold 1 and the pinion roll 7 and the sheet for the compressed rubber is wound around the mold 1 to join the cut surfaces of the sheet in a butted state. After a stickiness preventing material is wound around the surface of the sheet for the compressed rubber, the sheet for the compressed rubber is heated under pressure and closely brought into contact with the ridge-like parts 4 and grove-like parts 5 of the mold and shaped. At least a core wire and a stretched rubber sheet are successively wound around the surface of the unvulcanized sheet for the compressed rubber from which the stickiness preventing material is removed to form a belt molded object. This belt molded object is vulcanized and the obtained vulcanized sleeve is cut into a V-shape to manufacture the transmission belt.
