摘要:
The invention relates to a device (10) for evacuating a film chamber (28) using a pump system that comprises at least two vacuum pumps (20, 22), designed to evacuate the film chamber (28) alternately. In said device the suction capacity of the first vacuum pump (20) is greater than that of the second vacuum pump (22) and the final pressure achievable by the first vacuum pump (20) is less than that of the second vacuum pump (22).
