A centering device (1) for flat workpieces, especially sheet-metal blanks to be processed in a press, comprises a first table (100.1), which can be rotated about a first vertical axis (90), for receiving a workpiece and a second table (100.2), which can be rotated about a second vertical axis (90), for receiving a workpiece. The second table (100.2) is arranged to the side of the first table (100.1), and a support level of the first table (100.1) coincides substantially with a support level of the second table (100.2). The device furthermore comprises a rotation mechanism (45, 46, 50, 61), which is coupled mechanically to the first table (100.1) and to the second table (100.2) in such a way that the first and the second tables (100.1, 100.2) can be rotated jointly about a third vertical axis (50). If both tables (100.1, 100.2) are rotated jointly about the third vertical axis (50), the tables (100.1, 100.2) form a common supporting surface. In the other operating mode, the tables are rotated individually about the spaced vertical axes of rotation (90); the tables and their supporting surfaces thus move relative to one another. With the device according to the invention, it is thus possible without conversion work to correctly orient either an individual workpiece, which can take up the entire width of the centering device (1), or two narrower workpieces at the same time for subsequent processing.
