Abstract

L'invention appartient au domaine des équipements sous vide. Le dispositif de transport comprend une chambre sous vide, des unités d'herméticité d'entrée et de sortie, des moyens de transport, un mécanisme d'acheminement sous pression d'un matériau sacrificiel d'herméticité vers les unités d'herméticité sous pression, et un dispositif d'évacuation de l'installation de transport du matériau d'herméticité sacrificiel utilisé, depuis la chambre sous vide, après l'unité d'herméticité d'entrée mais avant l'unité d'herméticité de sortie. Le procédé de transport est caractérisé en ce que le matériau d'herméticité est alimenté dans les unités sous une pression assurant le transport hermétique de l'objet long via la chambre sous vide, et que le matériau utilisé est évacué de la surface de l'installation, depuis la chambre sous vide, depuis les cavités situées après les unités d'herméticité d'entrée et avant l'unité d'herméticité de sortie. A mesure que l'on utilise du matériau sacrificiel, on en rajoute.
