Abstract

　タイヤの製造工程を増やさず、高品質のタイヤが得られる未加硫ゴム押出部材を押出成型可能な未加硫ゴム押出装置を提供すること。 　未加硫ゴムＡ（ゴムチェーファー部分）の図面左側端部付近においては、未加硫ゴム（Ｂ）は、主ゴム流路（３４）の下側においては平行壁（５６）に沿って流れ、主ゴム流路（３４）の上側においては第２の傾斜面（３８）に沿って流れると共に、未加硫ゴム（Ｂ）の主流に対し、未加硫ゴム（Ｂ）の一部分が補助ゴム流路（４４）からは直角方向（矢印Ｂ方向）に押し出される。このため、未加硫ゴムＡ（ゴムチェーファー部分）の図面左側端部は、上側及び下側が未加硫ゴム（Ｂ）の流れによって挟まれる格好となる。
