Title
(EN) PRODUCTION METHOD OF BEAD FILLER MATERIAL WITH BEAD CORE
(FR) procédé de fabrication de matériau de remplissage de talon avec noyau de nervure
(JA) ビードコアを伴うビードフィラ素材の製造方法
Abstract
(EN)
In order to form linear grooves extending in the radial direction and contributive to smooth discharge of air in the surface on one side in the thickness direction after completing production of a bead filler material having an annular shape as a whole and becoming the winding laminate of ribbonlike rubber strip, the ribbonlike rubber strip (4) is laminated spirally around a bead core (3) arranged concentrically on a rotary substrate (1), and linear grooves becoming transfer of protrusions (2) provided on the rotary substrate (1) to extend in the radial direction are formed in the contact surface with the rotary substrate (1) over the entire circumference.
(FR)
Pour constituer des rainures linéaires s'étendant dans la direction radiale et contribuant à la décharge d'air en douceur à la surface d'un côté dans le sens de l'épaisseur au terme de la fabrication d'un matériau de remplissage de talon de forme dans l'ensemble annulaire devenant le stratifié d'enroulement d'une bande de caoutchouc en forme de ruban, la bande de caoutchouc en forme de ruban (4) est stratifiée en spirales autour d'un noyau de nervure (3) disposé de manière concentrique sur un substrat rotatif (1), et des rainures linéaires produites par les parties saillantes (2) disposées sur le substrat rotatif (1) pour s'étendre dans la direction radiale sont formées dans la surface de contact avec le substrat rotatif (1) sur toute la circonférence.
(JA)
 リボン状ゴムストリップの巻回積層になる、全体として円環形状をなすビードフィラ素材の製造の完了に伴って、それの厚さ方向の一方側の表面に、空気の円滑なる排出に寄与する、半径方向に延びる条溝を形成するべく、回転基板1上に同心配置したビードコア3の周りに、リボン状のゴムストリップ4を渦巻状に巻回積層して、回転基板1との接触面に、その回転基板1にラジアル方向に延在させて設けた突条2の転写になる条溝を全周にわたって形成する。
