Abstract
The invention concerns a machine for heat molding of wound thermoplastic materials provided with a mold and countermold subjected to a rapid approach movement and capable of restraining said material on the perimeter during molding. Said mold and countermold, in particular, slide within a bell carrying a punching blade capable of perimetral cutting of the molded pieces as a result of relative movement of the die or counterdie.
