To provide a method for manufacturing a toothed belt capable of reducing a frictional coefficient of a contact surface of the belt with a pulley while obtaining a high energy efficiency or a high production efficiency without advancing aging of a rubber without reducing adhesive properties of a toothed cloth with a surface of a tooth or a tooth space.
The method for manufacturing the toothed belt B comprises the steps of providing a plurality of teeth 3 on the back part 1 of the belt in which core wires 2 are embedded at a predetermined interval longitudinally of the belt, and coating the toothed cloth 5 along the surface of the teeth 3 and the surface of the tooth spaces 4 between the teeth 3 to form the belt B. The method further comprises the steps of laminating an adhesive rubber layer on one side surface of the cloth 5 dipped in a rubber paste, and coating a fluoropaint on the other side surface of the cloth 5. The method also comprises the steps of winding the cloth 5 on the outer periphery of a mold having grooves for molding the teeth with the coating surface of the fluoropaint disposed at an inner surface side, spirally winding the wires 2 on the outer periphery of the mold from above the cloth 5, and then further coating and winding a rubber sheet thereon. The method also comprises the steps of heating and vulcanizing the rubber sheet.
