EXPANDABLE DEVICE FOR CO-EXTRUDING

摘要

The device serves for extruding and includes an extrusion head for connection to at least two extruders. Moreover, in the area of the extrusion head, at least one tool is arranged for shaping a product composed of at least two extruded materials. At least one expanding element is arranged in an area of the tool facing the extrusion head. The expanding element is constructed so as to be essentially smooth in an area of a first surface and has at least one flow path for the extruded material in the area of its second surface facing away from the first surface.
