There is provided a tire structural member forming method capable of forming a structural member of a tire for a vehicle at a low cost, using a simple mechanism satisfactory in space efficiency and capable of setting a band-shaped member of a predetermined length on a forming drum in a high setting accuracy. The tire structural member forming method comprises the steps of applying a band-shaped member ( 3 ) of a predetermined length and a predetermined width to a transfer drum ( 12 ), moving the transfer drum ( 12 ) holding the band-shaped member ( 3 ) close to a forming drum ( 11 ) of a diameter smaller than that of the transfer drum ( 12 ) so that the leading end of the band-shaped member ( 3 ) is held between the transfer drum ( 12 ) and the forming drum ( 11 ), turning the transfer drum ( 12 ) and the forming drum ( 11 ) in opposite directions, respectively, at the same surface speed to transfer the band-shaped member ( 3 ) from the transfer drum ( 12 ) to the forming drum ( 11 ), and bonding together the leading and the trailing end of the band-shaped member ( 3 ) wound around the forming drum ( 11 ) to form a tire structural member on the forming drum ( 11 ). |
