A device for fixing objects by means of a vacuum, said device comprising a table extending in the directions of x and y and comprising a plurality of vacuum chambers which are formed in the table in the direction of z in order to evenly distribute a vacuum connected to the table, and comprising a tabletop which is arranged to cover the table and the vacuum chambers and has a plurality of perforation holes arranged in a grid-like manner, wherein a first vacuum chamber is arranged directly below the tabletop, said first vacuum chamber defining a minimum format of an effective surface area of the table in the directions of x and y and contacting two adjacent lateral surfaces of the table as well as being permanently connected to a vacuum extraction means which is connected to the table, and wherein further vacuum chambers, enabling an extension of the effective surface area beyond the minimum format, are arranged in contact with at least one side of the first vacuum chamber and/or at least one of the sides of the further vacuum chambers, and all further vacuum chambers have a switchable connection to the vacuum extraction means, characterised in that - a distributor housing is arranged at the table by means of which distributor housing the vacuum extraction means is connected to the table, - there are arranged on the table, in addition to the first vacuum chamber, a second vacuum chamber extending the first vacuum chamber to the entire extension in the direction of y, and a third vacuum chamber extending the first vacuum chamber and the second vacuum chamber to the entire extension in the direction of x, - the second vacuum chamber comprises a structure consisting of a plurality of parallel, line-forming grooves extending in the direction of x, which are connected to each other by a first connection channel in the direction of y and can be opened or closed serially with respect to the first vacuum chamber by means of a line-switching device, - the third vacuum chamber comprises a structure consisting of a plurality of parallel, column-forming grooves extending in the direction of y, which are connected to each other via a second connection channel in the direction of x and can be opened or closed serially with respect to the first vacuum chamber by means of a column-switching device, wherein the column-switching device is a rotary vane which is supported in the distributor housing so as to be positionable by means of a rotational drive, and - the third vacuum chamber can be opened or closed serially in the direction of y by means of the line-switching device, in a simultaneous, segmented manner and according to the number and positions of the line-forming grooves in correspondence with the second vacuum chamber, so as to achieve a column- and line-wise size adjustment of the effective surface area of the table in the direction of x and/or y. - a distributor housing is arranged at the table by means of which distributor housing the vacuum extraction means is connected to the table, - there are arranged on the table, in addition to the first vacuum chamber, a second vacuum chamber extending the first vacuum chamber to the entire extension in the direction of y, and a third vacuum chamber extending the first vacuum chamber and the second vacuum chamber to the entire extension in the direction of x, - the second vacuum chamber comprises a structure consisting of a plurality of parallel, line-forming grooves extending in the direction of x, which are connected to each other by a first connection channel in the direction of y and can be opened or closed serially with respect to the first vacuum chamber by means of a line-switching device, - the third vacuum chamber comprises a structure consisting of a plurality of parallel, column-forming grooves extending in the direction of y, which are connected to each other via a second connection channel in the direction of x and can be opened or closed serially with respect to the first vacuum chamber by means of a column-switching device, wherein the column-switching device is a rotary vane which is supported in the distributor housing so as to be positionable by means of a rotational drive, and - the third vacuum chamber can be opened or closed serially in the direction of y by means of the line-switching device, in a simultaneous, segmented manner and according to the number and positions of the line-forming grooves in correspondence with the second vacuum chamber, so as to achieve a column- and line-wise size adjustment of the effective surface area of the table in the direction of x and/or y.
