The hold-down device executes a loading stroke during which a compressive force is provided via a pneumatic force-exerting mechanism. The method also includes performing a setting operation, wherein the hold-down device is pressed against the workpiece in a pressure phase different from that of the loading stroke with a prespecified compressive force. The hold-down device moves in a guided manner on the mount via at least one guide column provided on the mount, and the at least one guide column includes a piston of a pneumatic drive that moves in a pneumatic cylinder.
