ABSTRACT:
The invention pertains to a system for the co-extrusion of multiple layers of thermoplastic material. The invention employs a modular system concept which enables a manufacturer to quickly exchange components to accept melt flow from a number of extrusion injectors to provide a number of extrudate layers for shaping by a standard sheet extruder die.
