ABSTRACT:
A system for providing shape and/or surface features to a moldable material includes, in an exemplary embodiment, at least two first opposed flat endless belts spaced apart a first distance, with each having an inner surface and an outer surface. The system also includes at least two second opposed flat endless belts disposed substantially orthogonal to the first two opposed endless belts and spaced apart a second distance. A mold cavity is defined at least in part by the inner surfaces of the at least two opposed flat endless belts. The system further includes a drive mechanism for imparting motion to at least two of the opposed flat endless belts.
