Apparatus for manufacturing rubber strip |
摘要 |
<p>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.</p> |
