Abstract

L'invention concerne un dispositif support destiné à maintenir une préforme de bouteille en polyéthylène téréphtalate, et à transférer celle-ci dans le sens du traitement lorsque la partie goulot de ladite bouteille est traitée thermiquement à des fins de cristallisation. Selon l'invention, un manchon de retenue permettant de maintenir l'anneau de base (Pa) de la préforme (P) est fait d'une matière d'isolant thermique afin de prévenir tout transfert de chaleur entre l'élément de retenue (200) et la préforme (P). Le manchon de retenue (400) est monté sur l'ouverture supérieure (202) de l'élément de retenue (200) de manière à prévenir tout transfert de chaleur entre la préforme (P) et cet élément (200), ce qui permet de chauffer rapidement et uniformément à une température adéquate et sans perte de chaleur la partie goulot de la préforme (P), et de cristalliser cette partie de manière satisfaisante.
