Beschreibung
Zusammenfassung:	Device and method for holding a workpiece (1) during surface treatment of the workpiece (1) by using a fluid and/or a gaseous medium, the workpiece (1) comprising a treatable surface (2), a non-treatable surface (3) and an intermediate surface (10) in between of the treatable surface (2) and the non-treatable surface (3), the device comprising a covering component (7) for covering the non-treatable surface area (3) of the workpiece (1), said covering component (7) comprising a hollow chamber (8) and an opening (51) for receiving the non-treatable surface (3), wherein the covering component (7) comprising a sealing-acting surface (6) that is in contact with the intermediate surface (10) of the workpiece (1) when the non-treatable surface (3) is placed in the interior of the ho\|low chamber (8), wherein the sealing-acting surface (6) of the covering component (7) is designed to fit the intermediate surface (10) of the workpiece (1) in such a manner that the interaction between the sealing-acting surface (6) and the intermediate surface (10) has a self-sealing effect, which results in sealing of the hollow chamber (8), so that penetration of the fluid and/or gaseous medium into the hollow chamber (8) is prevented, in this manner preventing contact of the fluid and/or gaseous medium with the non-treatable surface (3) of the workpiece (1) and allowing contact of the fluid and/or gaseous medium with the treatable surface (2) of the workpiece (1).
