Title:
METHOD OF MANUFACTURING SEALANT-CONTAINING TIRES, AND SEALANT-CONTAINING TIRE
Document Type and Number:
WIPO Patent Application WO/1999/047345
Kind Code:
A1
Abstract:
A method of manufacturing sealant-containing tires, wherein a green tire (24) in which a tire body (l) and an inner liner (2) are laminated on each other is set in upper and lower molds (29, 30) and subjected to vulcanization molding with a bladder (3l) expanded by an air pressure from the inside thereof, a mold releasing sheet (9), such as a fluororesin sheet having mold releasing property on one surface only thereof being inserted between the inner liner (2) and tire body (l) with the mold releasing property-carrying surface thereof opposed to the inner liner (2), whereby the vulcanization bonding of the inner liner (2) to the tire body (l) is prevented to enable a sealant chamber to be filled with a sealant to be formed to an accurate shape, forming the mold releasing sheet (9) out of a material which dissolves in the sealant enabling a decrease in the sealability of the tire caused by the mold releasing sheet (9) remaining in the sealant chamber to be avoided.
