Extrusion apparatus and method of extrusion for raw rubber mixes

摘要

The extrusion apparatus proposed effects an extrusion of the roller-spout type onto a cylindrical roller 7 associated with a profiled fixed wall 5 and a second extrusion of the roller die type onto a profiled roller 8 and an associated fixed wall 6, and then superimposes the extrusions in the passage between the rollers 7 and 8.
