Abstract: An apparatus for ultrasonic processing of workpieces is described. The apparatus comprises a converter plate, at least one feed unit mounted on said converter plate, at least one vibratory structure being coupled to said feed unit and having a converter, a sonotrode and a longitudinal axis, and adjusting means for adjusting the vibratory structure in at least two directions transversely to its longitudinal axis. The adjusting means include a plurality of fixing means arranged in the manner of a raster on said converter plate in such a manner that the feed unit can be fixed on the adapter plate with the aid of at least one fixing means selected from the plurality of fixing means.

Abstract: A device for ultrasonic treatment of a workpiece which at least two treatment spots has at least two resonant units which are adapted to be associated with corresponding ones of said treatment spots, each of the resonant units having a convertor and a sonotrode connected with the convertor, a joint mounting body arranged so that the resonant units are mounted on the joint mounting body in an arrangement which is dependent on a position of the treatment spots on the workpiece, and a displacement unit which is common for the resonant units and is coupled with the mounting body.
