Plasticizing machine which incorporates a closed belt of stainless steel 5 which is arranged on entrainment means which climb up the toothed sides of a calender 1 and of a plurality of support elements which define a circuit with large radii of curvature, the calender incorporating, in its inside, means for heating the metallic belt and a pressure roller 6 acting on the belt in the lower region. In the lower region of the metallic belt, there are a number of conveyor strips, and close to said metallic belt are preheating means, a cleaning roller together with an aspirator, means for cooling the strip and a roller for tensioning it. Likewise, it incorporates, near the inner end of the lower transportation strips, an aspirator which keeps the product adhered to the strips, and, in the rear region of the calender is a drum which supports a roll of treated (processed) polypropylene or polyethylene film. <IMAGE>
