Abstract
This thermoforming machine includes a thermoforming chamber having at least one heated air inlet through which heated air flows into the thermoforming chamber at a controlled pressure. The air inlet cooperates with a heated air flow distribution regulator located in the thermoforming chamber and through which the heated air flows out of the thermoforming chamber at a predetermined temperature. The regulator includes a heated air flow regulating mask receiving heated air flow, having a plurality of flow restricting elements providing different air flow restrictions.
