    • An apparatus for manufacturing a strip of rubber compounds comprises four extruders (2a, 2b, 2c, 2d) and a single extruder head (3). The extruder head (3) comprises an extruder die assembly (6) and a main body (4). The main body (4) is composed of a pair of laterally-spaced lateral blocks (11), a central block (10) disposed between the lateral blocks, and a pair of laterally-spaced sub blocks (13) disposed beneath the lateral blocks (11). The central block (10) has a pair of v-form side faces (15) extending in a v-shaped formation down to lateral ends of the bottom face (s1). The lateral blocks (11) are each provided with an upper mount face (21u) and a lower mount face (21L) on which two of the four extruders are respectively attached. An upper preforming channel (24ua, 24ub) extending from an extruder to the die assembly has a parting plane along the v-form side face (15). A lower preforming channel (24Lc, 24Ld) extending from an extruder to the die assembly also has a parting plane.
    • 用于制造橡胶化合物条的装置包括四个挤出机(2a,2b,2c,2d)和一个挤出机头(3)。 挤出机头(3)包括挤出机模具组件(6)和主体(4)。 主体(4)由一对侧向间隔开的横向块(11),设置在横向块之间的中央块(10)和一对横向间隔开的子块(13)组成,该子块设置在横向块 (11)。 中心块(10)具有一对v形侧面(15),其在v形地层中延伸到底面(s1)的侧端。 横向块(11)分别设置有分别安装有四个挤出机中的两个的上安装面(21u)和下安装面(21L)。 从挤出机延伸到模具组件的上部预成型通道(24ua,24ub)具有沿V形侧面(15)的分型平面。 从挤出机延伸到模具组件的下部预成型通道(24Lc,24Ld)也具有分型平面。
