とするものである。However, in the vulcanization method using the room-temperature vulcanization-type adhesive described above, it is difficult to obtain a reliable adhesive force, and the shape of a large rubber product is complicated (such as a three-dimensional shape). For this reason, there is a problem that the vulcanization mold at the joint is also very expensive. The present invention has been devised in view of such conventional problems,
Vulcanization bonding of rubber product seam joints can be performed easily and reliably without using a room temperature vulcanizing adhesive or a vulcanization mold used only for seam joints. It is an object of the present invention to provide an inexpensive large-scale rubber product joint vulcanizing method capable of ensuring its reliability.

価な継ぎ加硫を行うことが出来る効果がある。According to the present invention, an unvulcanized portion or a semi-vulcanized portion in a joint portion of a vulcanized rubber product manufactured separately is joined to a mold body as described above. A flexible heater is installed inside the joint of the vulcanized rubber product, and an expandable and contractible pressure bag housed in a housing case is installed outside the flexible heater, and the joint is heated by the flexible heater. Since the joints are vulcanized by pressurizing with a pressure bag, the vulcanization of the seam joints of rubber products is possible without using a vulcanization mold that is used only for room temperature vulcanizing adhesives or seam joints. Adhesion can be performed easily and reliably, stable adhesive strength and its reliability can be ensured, and there is an effect that inexpensive joint vulcanization can be performed.
