Abstract
An injector device for use in forming multilayer extrusions of plastic resins and a method for forming such extrusions. The apparatus includes an injector member that divides the extrudate from the first extruder into two layers and receives at least one extrudate from an additional extruder that is interposed by the injector member between the divided layers of the extrudate from the first extruder. The process includes producing plasticized resin by a first extruder, dividing the extrudate into two layers, producing extrudate from a second extruder, and injecting such extrudate between the two layers of the first extrudate.
