Abstract:  
A turntable having a number of pairs of opposed resilient gripping members mounted on nested ring members, one of the rings having its axis eccentrically translatable relative to the other, the translatable ring being pressure-biased in one direction transversely to its axis so that the space between the rings is greater at one end of a diameter to allow loading of workpieces between gripping members, the space closing with rotation of the rings to provide a firm grip of the workpieces passing through a subsequent peening zone, a portion of each workpiece being exposed to peening action and a portion shielded therefrom.
