A translating radial compression and holding mechanism includes radially movable dies defining a cylindrical cavity with movable radius. Apparatus coupled to the dies for sequenced lateral movement of the dies in a first direction and an opposite direction, substantially parallel to the central cavity to convey the compressed article along the axis of the central cavity. A compliant tube with a central opening larger than an article to be held, a case surrounding the tube along the longitudinal axis, and a plurality of cylindrical bushings positioned between the outer case and the tube. Mechanism associated with the tube for compressing the tube along the longitudinal axis to reduce the diameter of the central opening for gripping a second article residing therein, and the cylindrical cavity of the dies being positioned in axial alignment with the central opening of the tube. |
