A device for handling workpieces at a workpiece support defining a workpiece support plane includes a bearing structure extending with a main plane of the bearing structure parallel to the workpiece support plane. The bearing structure has bearing structure segments arranged next to one another parallel to the main plane, and the bearing structure segments define a planar extent of the bearing structure in the main plane. The device includes a guide device for the bearing structure segments, and the bearing structure segments are guided on the guide device such that the bearing structure segments can be positioned parallel to the main plane of the bearing structure. The device also includes retaining elements provided with the bearing structure segments, and the retaining elements are configured to be positioned on a workpiece and to be handled to fix the workpiece.
