Abstract: A device for fixing different-sized base area objects with a vacuum including on a table: first, second, and third vacuum chambers. The third chamber extending the first and second chambers to the entire x direction extension, and the second chamber having parallel, line-forming grooves in the x direction and connected to each other by a first connection channel in the y direction and being released/closed serially relative to the first chamber by a line-switching device. The third chamber includes parallel, column-forming grooves extending in the y direction and connected to each other via a second connection channel in the x direction and being released/closed serially relative to the first chamber by a column-switching device. The third chamber being released/closed serially in the y direction by the line-switching device, in a simultaneous, segmented manner according to the number and positions of the line-forming grooves in correspondence with the second chamber.
