Title
(EN) MANUFACTURING METHOD OF BEAD FILLER MATERIAL ACCOMPANYING BEAD CORE
(JA) ビードコアを伴うビードフィラ素材の製造方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To form a stripe groove, which contributes to the smooth discharge of air and extends in a radial direction, to the surface on one side in the thickness direction of a bead filler material, which is formed by winding and laminating a ribbon-shaped rubber strip and has an annular shape as a whole, accompanied by the completion of the manufacture of the bead filler material.

SOLUTION: The ribbon-shaped rubber strip 4 is wound around and laminated to the periphery of the bead core 3, which is concentrically arranged on a rotary substrate 1, in a vortex form and the stripe groove, which is formed by the transfer of the ridge 2 provided to the rotary substrate 1 so as to extend in a radial direction, is formed to the contact surface with the rotary substrate 1 over the whole periphery thereof.

【課題】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。
【解決手段】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。
