Abstract

A method of making shaped articles from highly condensed polyester melt and especially preforms for the blow molding of food and especially beverage containers. A melt is continuously withdrawn from the polycondensation reactor and is fed to the shape-imparting units, especially a multiplicity of injection-molding machines without solidification between the final reactor and the injection molders and without degassing between the final reactor and the injection molding machines.
