Abstract
Procédé de fabrication d'objets à parois minces. Ce procédé est caractérisé en ce que l'on produit dans le coeur d'une bande ou d'une feuille en matière thermoplastique cristalline un conditionnement de température spécial. Fabrication d'objets tels que tasses, assiettes et récipients semblables.A method of manufacturing thin-walled objects. This process is characterized in that a special temperature conditioning is produced in the core of a strip or sheet of crystalline thermoplastic material. Manufacture of articles such as cups, plates and similar containers.
