(EN) METHOD FOR FORMING GREEN TIRE, AND METHOD FOR PRODUCING PNEUMATIC TIRE
(FR) PROCÉDÉ DE FORMATION DE PNEU VERT, ET PROCÉDÉ DE PRODUCTION DE PNEU
(JA) 生タイヤの形成方法及び空気入りタイヤの製造方法
要約
(EN)
The disclosed methods include: a step (K1) that is for forming on a first drum (20) a tubular carcass (6R3) with an attached bead core, and that contains a step (K1a) for causing the end surfaces in the peripheral direction of a carcass ply member (6R1) wrapped once over a first drum (20) to be a zipper joint, forming a tubular carcass (6R2), and a bead core joining step (K1b) for expanding the diameter of the aforementioned tubular carcass (6R2), pushing the tubular carcass (6R2) against a bead core (5) that is inserted in the outside in the radial direction; a step (K2) for sequentially wrapping over a second drum (27) a base tire rubber member (Ga) containing an inner liner rubber member (G10a), forming a rubber laminate (11); and a tubular base tire forming step (K4) for transferring the aforementioned tubular carcass (6R3) with the attached bead core from the aforementioned first drum (20) to the second drum (27), and for pushing the rubber laminate (11) against the tubular carcass (6R3) with the attached bead core by means of expanding the diameter of the second drum (27), forming a tubular base tire (35).
(FR)
Les procédés selon l'invention comprennent : une étape (K1) consistant à former sur un premier tambour (20) une carcasse tubulaire (6R3) dotée d'une tringle attenante, et qui comprend une étape (K1a) consistant à amener les surfaces d'extrémité dans la direction périphérique d'un élément de pli de carcasse (6R1) enroulé une fois sur un premier tambour (20) pour constituer un joint de fermeture à glissière, ce qui permet de former une carcasse tubulaire (6R2), et une étape de raccordement de tringle (K1b) pour l'expansion du diamètre de la carcasse tubulaire susmentionnée (6R2) en poussant la carcasse tubulaire (6R2) contre une tringle (5) qui est insérée à l'extérieur dans la direction radiale ; une étape (K2) consistant à enrouler séquentiellement sur un second tambour (27) un élément de caoutchouc de pneu de base (Ga) contenant un élément de caoutchouc de calandrage intérieur (G10a), ce qui permet de former un stratifié de caoutchouc (11) ; et une étape consistant à former un pneu de base tubulaire (K4) pour transférer la carcasse tubulaire susmentionnée (6R3) avec la tringle attenante du premier tambour susmentionné (20) vers le second tambour (27), et pour pousser le stratifié de caoutchouc (11) contre la carcasse tubulaire (6R3) avec la tringle attenante au moyen de l'expansion du diamètre du second tambour (27), ce qui permet de former un pneu de base tubulaire (35).
(JA)
第1のドラム(20)上で一周巻きしたカーカスプライ部材(6R1)の周方向端面同士をジッパージョイントして筒状カーカス(6R2)を形成するステップ(K1a)と、前記筒状カーカス(6R2)を拡径してその半径方向外側に外挿するビードコア(5)に押し付けて接合するビードコア接合ステップ(K1b)とを含み、前記第1のドラム(20)上でビードコア付きの筒状カーカス(6R3)を形成する工程(K1)、第2のドラム(27)上でインナーライナゴム部材(G10a)を含む台タイヤ用ゴム部材(Ga)を順次巻回してゴム積層体(11)を形成する工程(K2)、前記ビードコア付きの筒状カーカス(6R3)を、前記第1のドラム(20)から第2のドラム(27)まで移送し、かつ第2のドラム(27)の拡径によりゴム積層体(11)をビードコア付きの筒状カーカス(6R3)に押し付けて筒状台タイヤ(35)を形成する筒状台タイヤ形成工程(K4)を含む
