タイヤ製造方法
Document Type and Number:
Japanese Patent JP6718692
Kind Code:
B2
Abstract:
When a sealing layer is formed of a strip-like sealant on an inner surface of a tire, thickness variations of the sealing layer can be easily restrained. A sealing layer (17) is formed of a strip-like sealant (20) on an inner surface (5) of a tire (1). A pair of side surfaces (21) of the sealant (20) is located on both sides in a width direction (H) of the sealant (20) and is inclined toward the same side in the width direction (H) of the sealant (20) with respect to a thickness direction (R) of the sealant (20). The sealant (20) is spirally arranged on the inner surface (5) of the tire (1) with the adjacent side surfaces (21) of the sealant (20) being overlapped with each other, so that the sealing layer (17) is formed.
