PROBLEM TO BE SOLVED: To provide a manufacturing method for a transmission belt capable of making a cogged belt at a low cost by exactly forming a reinforcing fabric with a surface of a forming die having a groove portion and a protrusion by turns. SOLUTION: The manufacturing method of the transmission belt comprises the steps of (1) applying an adhesive agent 7 on the top 8 of the protrusion 4 of the forming die 1, (2) forming the reinforcing fabric 30 placed on the surface of the forming mold so that the reinforcing fabric is made to tightly come into contact with the groove portion 5 and the protrusion 4 by a pinion roll 10, (3) winding a sheet 35 for a compressing rubber around the forming die, mating and jointing the cut surfaces, (4) forming the sheet 35 for the compressing rubber with the protrusion 4 and the groove portion 5 by heating and compressing it, (5) orderly winding at least a core wire 50 and an expandable rubber sheet 53 around the surface of the formed unvulcanized sheet 35 for the compressing rubber, and vulcanizing them, and (6) cutting the vulcanized belt sleeve into a V-shape.
