Patent ID: 7758714

Claim:
A method of manufacturing tire structural members, comprising: providing cord reinforced bands having therein reinforcing cords which are arranged at different cord pitches from one cord-reinforced band to another, wherein said providing cord reinforced bands comprises: calculating a calculated width for each cord-reinforced band as a function of the cord pitch of each cord-reinforced band, providing an increment of un-reinforced material on at least one end of the calculated width of each reinforced band to produce cord reinforced bands having different cord pitches and the same predetermined fixed width; cutting each of the cord-reinforced bands into a plurality of cord-reinforced strips of a predetermined length; and for each cord-reinforced band, successively arranging the cord-reinforced strips such that side edge parts of adjacent cord-reinforced strips of the same cord-reinforced band overlap each other and bonding the adjacent cord-reinforced strips together to obtain the tire structural members, wherein said cord-reinforced bands having different cord pitches are produced to have the same predetermined fixed width without regard to the cord pitches thereof, wherein the width of the increment is determined based on the difference between the fixed width and the calculated width of each cord reinforced band, and wherein said cord-reinforced bands having different cord pitches are produced to have different calculated widths based on the different cord pitches.
