Abstract

L'invention concerne une machine d'emballage sous vide pour la fabrication d'un emballage sous vide d'air d'un produit agencé entre une feuille supérieure et une feuille inférieure, ladite machine pouvant être également utilisée de manière fiable pour des feuilles de couverture plus épaisses ou des emballages rigides. La machine d'emballage sous vide selon l'invention comporte un poste de formage et au moins un dispositif de levage (10) présentant des outils, comprenant une partie supérieure d'outil (13) et une partie inférieure d'outil (12), ainsi qu'un système de levage permettant un un premier et un deuxième mouvement de levée ou de fermeture. La machine présente également au moins un vérin d'outil (19) pour une levée verticale de la partie inférieure d'outil (12) ainsi qu'un arbre de vérin (15) guidé à travers la partie inférieure d'outil (12) et muni d'un ergot de blocage (16), l'arbre de vérin (15) étant guidé à travers une ouverture (17) de la partie inférieure d'outil (12) dont la section transversale correspond à celle de l'ergot de blocage (16).
