Abstract
A mechanism for the contactless gripping and positioning of a component having a planar peripheral edge region, including a sound producing device producing a pattern of levitation sound waves for keeping the component in suspension at a selected position. The sound producing device is configured wherein only the peripheral edge region of the component lies in the sound wave pattern to be acted upon thereby and is fixed in the sound wave pattern by Bernoulli forces. The total surface area of the sound producing device is less than the component's total surface area facing the sound producing device.
