Abstract: A method and apparatus are provided for applying multidirectional vibrations to a resilient support. The excentric of the unidirectional vibration generator cooperates with a spherical shaped member mounted for free rotation on the lower face of the vibrating table connected to the base through springs. The unidirectional vibration generator is carried by a plate parallel to the vibrating table and which is rotated about an axis X--X which is perpendicular thereto, under the action of a motor. This rotation of the unidirectional vibration generator ensures the application of multidirectional vibrations to said table.
