ABSTRACT:
A composite torroid forming cup for an automated torroid-forming apparatus has a molded plastic upper closure and a bottom reinforced cup section. The upper closure has a hinge pin and an upper non-stick partial torroid forming surface. The bottom reinforced cup section has a substantially rigid reinforcing subframe and a plastic outer body portion that may be molded about the subframe. The bottom reinforced cup section has a bottom non-stick, partial torroid-forming surface. A method of making a composite dough torroid forming cup has several steps. A flat reinforcing plate is perforated with a plurality of apertures, and studs are spot-welded in a spaced relation onto the reinforcing plate. The reinforcing plate is positioned on a forming die and is formed thereon. The reinforcing plate is positioned in a mold, and plastic is molded about the reinforcing plate to form a reinforced bottom cup section. Plastic closures are formed in a closure mold, and are hingedly mounted on the reinforced bottom cup section to make a full dough forming cup. A shape-retaining core is provided within the cup to maintain the cup tightly fitting about the core. The cup is immersed in chilled water for cooling purposes.
