Abstract

Dans la formation d'articles creux à molécules orientées ayant une section sensiblement ovale ou ayant la forme d'un triangle sensiblement équilatéral à partir de préformes en matériau thermoplastique par un procédé qui comprend l'étirage de la préforme dans le moule chauffé à la temperature d'orientation moléculaire, les perfectionnements permettent une meilleure distribution du matériau dans les zones les plus éloignées des axes des articles lorsque le matériau thermoplastique est un téréphtalate de polyalkylene ayant une viscosité inhérente d'au moins 0,55, qui implique la limitation du rapport de définition d'angle à une valeur comprise entre environ 9 du rapport de déviation circulaire à une valeur ne dépassant pas environ 2,4 en coupe pendant l'étirage et le contrôle de l'allongement axial et de l'allongement radial maximum des préformes dans des limites prédéterminées.
