Abstract

Abstract Production of a marbled product is accomplished by associating a plurality of product constituent streamlets in a desired cross-sectional pattern or configuration, diverting a portion of one or more of the product constituent streamlets of the pattern into one or more of the other product constituent streamlets of the pattern, joining the associated streamlets into a unified marbled product stream, and then dispensing the marbled product stream into a product container.
