Patent attributes
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).
