ABSTRACT:
A die system for the extrusion of polymer permits external cleaning and maintenance without shutting down the operation. Removable die inserts are located on one or both sides of the die opening section through which polymer is extruded. The inserts are spaced from the die opening section, by a very small distance, so as to avoid interfering with the opening section. When molten polymer accumulates and burns in areas surrounding the die opening section, the inserts can be removed and replaced without interrupting the extrusion of polymer.
