To provide a method for reproducing a belt for a Rotocure (R) apparatus, capable of easily reproducing the belt as a void-free rubber sheet reduced in flaw.

A metal mesh belt 51 is wound around the Rotocure (R) apparatus (a rotary curing press) and the unvulcanized rubber sheet R extruded from an extrusion molding machine 6 is laminated on the metal mesh belt so as to be held between a vulcanizing roll and the metal mesh belt while the metal mesh belt is fed. Since the metal mesh belt coated with an adhesive is set to the Rotocure (R) apparatus and the unvulcanized rubber sheet just extruded from an extruder is laminated to the metal mesh belt, the unvulcanized rubber sheet is relatively high in temperature than before and also good in its surface state and tackiness. By vulcanizing the unvulcanized rubber sheet on the metal mesh belt, a surface layer wherein the interior of sheet is also good can be formed.
