| description | The present invention is directed to an improved apparatus and method for manufacturing completed foam plastic containers. An endless mandrel chain (46) carries cup forming mandrels (FM) along a manufacturing path. After each mandrel is preheated, a bottom blank (BD) is placed on the mandrel bottom and held there by a vacuum. A cylindrical blank (10C) formed from longitudinally stretch-oriented foam sheet material is then placed onto the mandrel. This cylindrical blank (10C) is tightly tamped onto the mandrel (FM) and is clamped in place. Radiant heat is then used to shrink form a finished container. The bottom is then sealed to the cylindrical blank and the mandrel is transferred to a curling assembly (TCT) where the top edge portion of each finished container is lubricated and then curled to form a finished rim. The apparatus of the present invention may form containers having a dual tapered configuration which allows the containers to be more tightly stacked. |
