Multiple layer combining adapter

摘要

This invention relates to the field of multiple layer plastic extrusion, and more particularly to assemblies in which thin or micro-layers of polymer material are formed which polymer material may be from two or more individual extruders, and delivered to a multilayer combining adapter in association with an extruder die or other utilizations. The combining adapter of this invention is referred to herein as a flow velocity profiler (FVP) and includes a cartridge assembly body that is formed with individual cavities that receive one of a plurality of individual precision layering inserts. Changing individual inserts is less time intensive than changing an entire body as required in prior art.
