    • An extruder has a discharge opening formed into a rectangular shape by a pair of end surface forming walls and a pair of side surface forming walls. A die configured to discharge a rubber material pressed out towards the discharge opening as two bands separated from each other at the discharge opening is provided having a height spanning between the pair of end surface forming walls and inserted so as to be movable and adjustable in the axial direction of the discharge opening at the center of the pair of side surface forming walls. The width between the left-right side surface of the die is formed at dimensions that become smaller from the base surface toward the tip surface. A convex curved surface configuring the left-right side surfaces is formed having a radius of curvature that becomes smaller from the base surface toward the tip surface of the die.
    • 挤出机具有通过一对端面形成壁和一对侧面形成壁形成为矩形形状的排出口。 一种模具,被配置为将排出口上的两个带彼此分离的排出口的橡胶材料排出,该高度跨过一对端面形成壁并插入,以便能够在 在一对侧面形成壁的中心处的排出口的轴向方向。 模具的左右侧面之间的宽度形成为从基面朝向前端面变小的尺寸。 形成左右侧面的凸曲面形成为从模具的基面朝向模头的前端面变小的曲率半径。
