The apparatus includes means for unrolling the strip from a supply spool and centering the strip onto a transfer drum; means for applying the strip onto the transfer drum and cutting the strip to the desired length; and means for axially moving the transfer drum to a position adjacent a tire building drum where the rubber strip is applied to the building drum.
