ABSTRACT:
Methods and apparatus are provided for making multilayer plastic articles. Initially, two or more streams diverse thermoplastic materials are provided. Layers are foraged from these streams and are arranged in a layered first composite stream. The first composite stream may be directly formed into a desired configuration by a molding process or may be manipulated to form a second composite stream having an increased number of layers before being formed into the desired configuration. The resulting articles are comprised of a number of discrete and substantially continuous layers.
