Double flow channel for an extruder head

摘要

The invention provides a method and an extruder head (5) for forming simultaneously two or more elastomeric strips of predetermined cross-sectional profiles from a material. The material is received from an extruder into an inlet channel (10) where it is divided into a first and a second angled flow passage (40, 50). The material passes through a transition area (80) where it is straightened out and the center of mass of the material is moved into alignment with the center of a divertor (100) located in a downstream discharge channel (90). The material is then discharged into a preformer and die (60).
