Title:
MANUFACTURING METHOD OF TIRE REINFORCING MATERIAL AND MANUFACTURING METHOD OF PNEUMATIC TIRE USING THE TIRE REINFORCING MATERIAL
Document Type and Number:
Japanese Patent JP3967348
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve uniformity in stiffness at a joint of plies of a cord fabric and to improve dynamic uniformity of a tire when it is shaped and vulcanized.
SOLUTION: A method of manufacturing a tire reinforcing material which is a cord fabric constructed of warp cords arranged in parallel with each other and wefts arranged substantially orthogonally to the above warp cords, includes: a topping step for coating with rubber the cord fabric having the above wefts folded back at the warp cords at opposing ends of the cord fabric to produce a ply; a cutting step for cutting the above ply into ply pieces each having a predetermined length; a joint forming step for removing one to five warp cords at each of opposing ends of the above ply to form a joint; and a joining step for joining together the joint of one of the ply pieces and the joint of another ply piece.
