Abstract
The process and the apparatus provide for starting from a strip or sheet which is continuous, of plastic material, which is first of all heated by infrared heating means (36) and then passed in contact with three heated rollers (30, 34, 32), to achieve a uniform distribution of the temperature both above and below said strip, after which, in the hot condition, said strip stops and is indexed towards a thermoforming machine (not shown), in which the articles are formed during the stops due to said indexing. This process avoids the disadvantages of the conventional infrared heating methods with which a uniform distribution of the temperature is not achieved.
