To reduce installation space of a molding apparatus for a green tire comprising a carcass play having a hollow portion.SOLUTION: A molding apparatus 30 molds a green tire 1 comprising a discontinuous carcass play 14 constituted of a pair of ply pieces 15. The molding apparatus 30 comprises: one servicer 41 that feeds out a belt-like first ply sheet 15' from which a plurality of ply pieces 15 are molded; a drum 60 around which the first sheet 15' fed out from the servicer 41 is wound; a first cutting unit 55 that cuts the first sheet 15' in order to separate the one ply piece 15: a moving mechanism 70 that relatively moves the servicer 41 and the drum 60 in an axial direction of the drum 60; and a control unit 80 that controls the moving mechanism 70.SELECTED DRAWING: Figure 1 【課題】中抜き部を有するカーカスプライを備えるグリーンタイヤの成型装置における設置スペースを削減する。【解決手段】成型装置３０は、一対のプライ片１５からなる不連続なカーカスプライ１４を備えるグリーンタイヤ１を成型する。成型装置３０は、複数のプライ片１５を成型するための帯状の第１シート１５'を送り出す１個のサービサ４１と、サービサ４１からの第１シート１５'を巻き付けるドラム６０と、１つのプライ片１５を分離するために第１シート１５'を切断する第１切断部５５と、サービサ４１及びドラム６０をドラム６０の軸方向へ相対的に移動させる移動機構７０と、移動機構７０を制御する制御部８０とを備える。【選択図】図１
