Apparatus for co-extruding elastomeric compounds |
摘要 |
Forming a rubber component includes using a single extrusion head to co-extrude layers each having a rubber mixture. The head has a main extruder with a channel for each rubber mixture leading to a single extrusion orifice. A micro-extruder simultaneously extrudes another rubber mixture across the layers produced by the main extruder. The micro-extruder has an nozzle opposite one face of the orifice of the main extruder. An Independent claim is included for a co-extrusion apparatus for performing a rubber component. |
