Abstract
A method of applying a looped rubber member on a tire building drum having grooves formed in the periphery thereof, comprising the steps of inserting at least two pairs of retaining members into the looped rubber member in a first direction; retaining the looped rubber member on the retaining members; rotating the retaining members with the looped rubber member retained thereon toward the tire building drum to a second direction which is opposite to the first direction; forming the looped rubber member on the retaining members into a substantially circular configuration; transferring the substantially circular looped rubber member toward the tire building drum into a first position in which the center of the looped rubber member is in axial alignment with the longitudinal center axis of the tire building drum; further transferring the substantially circular looped rubber member from the first position into a second position in which the looped rubber member surrounds the periphery of the tire building drum radially contracted; receiving the retaining members in the grooves in the periphery of the tire building drum; applying the substantially circular looped rubber member on the periphery of collapsible tire building drum; and withdrawing the retaining members from the grooves in the periphery of the tire building drum.
