  • Patent number: 10195835
    Abstract: The method includes forming, on a bonding object surface of a bonding object, an adhesive layer for bonding an unvulcanized rubber onto the bonding object surface, through use of an adhesion sheet and a fixing device. The fixing device includes an enclosed chamber. The fixing device is configured such that a gas in the chamber can be discharged and a gas can be introduced into the chamber. The fixing device includes a table which is arranged in the chamber and on which the bonding object can be placed. The adhesion sheet includes a top coating adhesive layer formed on a film and an undercoating adhesive layer formed on the top coating adhesive layer.
