Abstract

L'invention concerne un dispositif de transport de contenants (2) selon le préambule de la revendication 1 et, en particulier, un dispositif de transport de contenants sous la forme de bouteilles, de préférence de bouteilles en PET. L'aspect essentiel du dispositif de transport de contenants selon l'invention réside dans le fait qu'au moins un élément coulisse (11) déplaçable radialement par rapport à l'axe de machine (MA) permet d'engager dans un mouvement de pivotement guidé de manière forcée le premier et le deuxième bras de préhension (5.1, 5.2) d'un préhenseur de contenant correspondant, ledit élément coulisse (11) présentant une première courbe de commande (12) servant à commander le premier bras de préhension (5.1) et une deuxième courbe de commande (13), séparée de la première, servant à commander le deuxième bras de préhension (5.2), la première et la deuxième courbe de commande (12, 13) étant conçues pour permettre le guidage forcé du bras de préhension respectif (5.1, 5.2) entre la position de préhension et la position de relâchement.
