To provide a method for manufacturing a transmission belt with a mark where the mark attached on a back surface is not vanished while using a method for vulcanization-molding a belt body with an orthogonal molding, and favorable appearance is obtained.
The method for manufacturing a transmission belt with a mark includes steps of laminating a film laminated body formed by overlapping a thermoplastic resin film 8 for printing which is printed with a mark 7 on a back face and has a melting point lower than a vulcanization-molding temperature and a mold release resin film 9 having a melting point higher than the vulcanization-molding temperature on a back face side of an outer canvas 2 laminated at a periphery around a molding drum 21 at the inner periphery side; and peeling the mold release resin film 9 from the outermost periphery of a belt body after vulcanization molding. As a result, the mark 7 is prevented from being vanished by covering the mark 7 attached on the back face with the thermoplastic resin film 8 for printing which melts in the vulcanization-molding process, and the thermoplastic resin film 8 for printing is prevented from adhering to a rubber jacket 22 at the peripheral side by blocking the peripheral side of the thermoplastic resin film 8 for printing with the mold release resin film 9 which is not melted.
