Abstract
【解決手段】 回転軸が互いに平行に配置された少なくとも1本の成形ローラ1及び少なくとも1本の補助ローラ2と、これら成形ローラ1及び補助ローラ2の相対的な位置を調整する位置調整機構3と、成形ローラ1と対をなす圧着装置4とを備えた成形装置を用いたタイヤ構成部材の成形方法である。成形ローラ1及び補助ローラ2に円筒材5を掛け回し、成形ローラ1及び補助ローラ2の相互間隔を拡張することで円筒材5を成形ローラ1及び補助ローラ2に対して密着させ、円筒材5を回動させながら成形ローラ1と圧着装置4との間で円筒材5の外周面にシート材6を圧着する。
【選択図】 図1
Description
図1は本発明のタイヤ構成部材の成形方法を実施するための成形装置の一例を概略的に示す斜視図であり、図2はその側面図である。図1に示すように、この成形装置は、回転軸が互いに平行に配置された成形ローラ1及び補助ローラ2と、これら成形ローラ1及び補助ローラ2の相対的な位置を調整する位置調整機構3と、成形ローラ1と対をなす圧着装置4とを備えている。円筒材5は成形ローラ1及び補助ローラ2に跨がるように掛け回され、シート材6は成形ローラ1と圧着装置4との間で円筒材5の外周面に圧着されるようになっている。
タイヤサイズ変更への対応性:
タイヤサイズを195/65R15から205/55R16に変更した場合のタイヤ構成部材の成形能力を評価した。評価結果は、以下の基準にて示した。
○:ローラの段替不要でローラ間隔の調整により変更したサイズのタイヤ構成部材を成 形することができる。
×:成形ドラムの段替により変更したサイズのタイヤ構成部材の成形が可能になる。
円筒材の周長バラツキへの対応性:
円筒材の周長が設計値の1220mmよりも30mm長い場合のタイヤ構成部材の成形能力を評価した。評価結果は、以下の基準にて示した。
○:ローラ間隔の調整により周長バラツキに対応でき、問題なくタイヤ構成部材を成形 することができる。
×:円筒材が成形ドラムの表面に密着せず、タイヤ構成部材の成形ができない。
部材間の圧着状態:
○:部材間にエア溜まりが全く存在しない。
×:部材間のドラム段差箇所に対応する部位にエア溜まりが存在する。
