Abstract
An immobilizing device particularly useful during processing or testing flat workpieces includes an air-cushion unit carried at the lower end of a carrier member and having an annular skirt defining with the workpiece, an air-cushion chamber effective, when pressurized, to cause the air-cushion unit to hover over the workpiece to permit relative movement between the air-cushion unit and the workpiece and table, while immobilizing and flattening the board with respect to the table.
