METHOD FOR MANUFACTURING RUBBER MEMBER AS CONSTITUENT OF TIRE, AND PNEUMATIC TIRE USING RUBBER MEMBER AS CONSTITUENT OF TIRE

摘要

PROBLEM TO BE SOLVED: To enhance uniformity in a tire. SOLUTION: This method provides a method for manufacturing a cylindrical rubber member G as a constituent of the tire by winding a rubber substrate 1, where the rubber substrate 1 is composed of a laminate 4 that piles a plurality of belt-like sheets of 0.5-4.0 mm in thickness T. By shifting the position of one end E1 of the each belt-like sheet 3 in length direction in order, in accordance with the winding, the position of the joint J between the one end E1 and the other end E2 of the each belt-like sheet is shifted to the circuit direction, respectively.
