In Japanese Patent Laid-Open Publication No. JP-A-2004-134, a mat is manufactured by joining a raised base fabric and an unvulcanized rubber sheet, sucking the unvulcanized rubber sheet side by a suction part, and heating and vulcanizing the unvulcanized rubber sheet side. At this time, the base fabric surface side is covered with a flexible sheet larger than the unvulcanized rubber sheet, and the unvulcanized rubber sheet is heated and vulcanized while the flexible sheet is pressurized by gas pressure in a closed space. A method of manufacturing a mat to be vulcanized was proposed. A similar method is also disclosed in Japanese Patent Laid-Open No. 19127/1992.

圧空間を減圧する吸引手段とを備えている。Further, the upper closed space may have a relatively higher pressure than the lower space in order to bring the plurality of joining members into close contact with each other efficiently. That is, it is only necessary to inject gas into the upper closed space, or only the lower space may be depressurized. In order to increase the adhesion of the joining member, it is preferable to pressurize gas into the upper closed space and reduce the pressure in the lower space. Therefore, a preferable apparatus is a base having a plurality of holes communicating with the decompression space, a press-fitting means for pressurizing gas into a closed space formed by a rubber sheet and a lid, and a suction means for depressurizing the decompression space. Is equipped with.
