Abstract

　支持体上に複数配列させたカーカスコードにビードコアを配置してグリーンタイヤを形成する際に、カーカスコードを所定位置に精度良く正確に配置する。 　複数のカーカスコード（Ｃ）をコア（２１）の全周に亘って配列させ、その端部を端部保持手段（３０）に貼り付けて、コア（２１）の軸方向外側に離間させて、かつコア（２１）との間に張力が付加された状態で保持する。このカーカスコード（Ｃ）の外側から、ビードコア（６０）をコア（２１）のビード成型部（２４）に向かって移動させ、端部が保持されたカーカスコード（Ｃ）に当接させてコア（２１）側に押圧する。この押圧力で、カーカスコード（Ｃ）をビードコア（６０）の移動方向に押し込んで、コア（２１）に向かって張力が付加された状態で変位させ、カーカスコード（Ｃ）をコア（２１）の側面に順次配置しつつ、ビードコア（６０）をカーカスコード（Ｃ）を挟んでビード成型部（２４）に配置する。
