ABSTRACT:
An apparatus for manufacturing a recapped tire includes: a vulcanizer in which is filled a fluid for vulcanization for adhering by vulcanization a base tire and a tread; a rim to which the base tire is mounted; an envelope which is annular and covers an outer periphery of the base tire; suction means for sucking air from between the base tire and the envelope; a tube which is annular and expandable and contractible, the tube being provided at a portion of the rim corresponding to an outer side of the base tire along a tire axial direction, and pushing the envelope against a bead portion of the base tire; a stopper provided at a portion of the rim corresponding to an inner side of the base tire along the tire axial direction, and preventing movement of the bead portion toward the inner side of the base tire along the tire axial direction; and internal pressure providing means for providing internal pressure to the tube so as to inflate the tube. Accordingly, adhesion by vulcanization of the tread can be effected in a short time without shortcomings in manufacturing.
