Summary:To provide a molding apparatus enhancing uniformity of a tire.SOLUTION: A molding apparatus 2 includes a pair of set rings 28 for holding a pair of bead members on the outside of a carcass tube in the radial direction. The pair of set rings 28 are formed with a plurality of segment pairs 30 aligned in the circumferential direction. In each of the segment pairs 30, one segment 32 and the other segment 32 are disposed opposing to each other in the axial direction. The molding apparatus includes a function to move each of the segment pairs 30 independently from the other segment pairs 30 in the axial direction, and a function to alter the interval in the axial direction between the one segment 32 and the other segment 32 while holding the central line of the segment pairs 30 in the axial direction to be constant.SELECTED DRAWING: Figure 2 【課題】タイヤのユニフォミティを向上させる成形装置の提供。【解決手段】成型装置2は、一対のビード部材をカーカス筒体の半径方向外側に保持する一対のセットリング28を備えている。一対のセットリング28は、周方向に並べられた複数のセグメント対30で形成されている。それぞれのセグメント対30において、一方のセグメント32と他方のセグメント32とは、軸方向に対向して配置されている。成形装置は、それぞれのセグメント対30を他のセグメント対30から独立に軸方向に移動させる機能と、セグメント対30の軸方向の中心線を一定に保持しつつ、一方のセグメント32と他方のセグメント32との軸方向間隔を変更する機能とを備えている。【選択図】図2
