A lock chamber is provided in the main vacuum chamber through which articles can be inserted and removed.

In the method articles are introduced into the main vacuum chamber through a lock chamber, and they are intermittently progressively advanced through a plurality of work stations in the main vacuum chamber and then are removed through the lock chamber.
