Abstract:
1. A method of forming a cord reinforced tire structural member, comprising: forming strips having a width of approximately π inches and reinforced by cords embedded therein; successively arranging a predetermined number of the strips in side-by-side adjacent disposition; and joining together side edge parts of the strips to form a cord-reinforced tire structural member; setting a desired number of the cords to be included in the cord-reinforced tire structural member for each of tire sizes in units of inches; dividing the desired number of the cords by each of the tire sizes to calculate a quotient for each tire size, thus obtaining quotients for respective tire sizes; calculating a mean value of the thus obtained quotients; and determining an integral part of the mean value to be the number of the cords to be included in each of the strips.
