Abstract
Methods and apparatus for forming continuous lengths of material with non-uniform cross-sections are disclosed. In accordance with one aspect of the present invention, a method for forming a continuous length of material that is of a substantially non-constant cross-section includes providing the material to a single shaping wheel. The material is in a first state, and the single shaping wheel includes a template that is arranged to form a three-dimensional shape using the material. The method also includes shaping the material to form an extended strip from the material, as well as at least one three-dimensional shape in the extended strip. The extended strip and the three-dimensional shape being formed using substantially only the single shaping wheel. In one embodiment, the method includes cooling the extended strip by cooling the material from a molten state to a solid state.
