ABSTRACT:
Thermal forming of objects made from plastic material if performed by machine which has first, second and third sectors. The first sector includes structure for unrolling a coil of plastic sheet material. The second sector receives and transports the plastic sheet from the first sector and also heats the plastic sheet as it is moved through the second sector. In the third sector, there is a rotating die which has a plurality of die faces. Each of the die faces is an object form. A first stage of the rotating die receives the heated plastic sheet from the second sector and deforms the heated plastic sheet around the object form to create the object shape. A second stage of the third sector cools the deformed plastic and removes the object from the die faces.
