<p>The apparatus comprises an endless tunnel (1) whose wall is provided with openings (2 and 5, respectively) giving access to processing chambers (3, 4) and a lock chamber (6) which has a panel (7) which seals the apparatus from the external environment. A conveyor (11) which follows a closed path is arranged in the tunnel (1) and is provided with seats (12, 13) for containers (14) with articles to be processed and transport means (17, 18, 19) for introducing articles, which are carried by the conveyor (11) into positions each of which is opposite to a chamber (3,4, 6), into the respective chamber. The apparatus has means (21-26) by which the environments in the tunnel (1) and in each of the chambers (3,4,6) can be controlled. The chambers (3,4,6) can each be sealed from the tunnel (1) in a vacuum-tight manner. By means of the apparatus, articles, which are screened from the surroudings in a vacuum-tight manner, can be subjected in controlled environments to a variety of processing steps.</p> |
