    摘要: A green tire (24) prepared by superposing an inner liner (2) onto the inner surface of a tire body (1) is set in an upper die (29) and a lower die (30). In this condition, a pressure bag (31) placed inside the green tire (24) is expanded by air pressure to perform vulcanization and forming. At this time, a mold release sheet (9) such as a fluoro resin sheet having a mold releasing property on one surface only is interposed between a part of the inner liner (2) and the tire body (1) in such a manner that the surface having the mold releasing property is opposed to the inner liner (2). Accordingly, the inner liner (2) is prevented from being bonded by vulcanization to the tire body (1), thereby forming a sealant chamber having a proper shape for charging a sealant thereto. In case the mold release sheet (9) is formed of a material soluble in the sealant, a reduction in sealability of the sealant due to the mold release sheet (9) left in the sealant chamber can be avoided.

    摘要: To make it possible to precisely bond a tube blank having thickened portions projecting from an outer wall surface of a retention mold. A tube blank is formed of natural rubber and is provided with an air chamber peripheral wall, a sealant chamber peripheral wall and a partition. The tube blank has ends held by the retention mold which are bonded in an annular shape. The retention molds include an upper mold and a lower mold having respective retaining surfaces. Indents are provided in the retaining surface of the lower mold for engaging with the thickened portions projecting from the air chamber peripheral wall of the tube blank. By forming the indents in the retention surfaces of the lower molds, it is possible to hold the two ends of the tube blank without warping the tube blank and to precisely bond the two ends of the tube blank together.
