Abstract: A segmented sleeve restrained at one end is constrained to be kept in contact with a mandrel which the sleeve encircles. The mandrel is slideably mounted inside the sleeve and has an enlarged diameter which radially expands the sleeve as the enlarged portion passes by.

Abstract: A METHOD AND APPARATUS USING DISPOSABLE SLEEVES FOR COLDWORKING OF HOLES. THE APPARATUS USES A TAPERED OVERSIZED PLUG ELEMENT WITH A THEREON POSITIONED THIN-WALLED SPLIT SLEEVE. THE PLUG ELEMENT IS INSERTED WITH THE SLEEVE INTO A HOLE. WHEN THE PLUG ELEMENT IS PULLED BACK THROUGH THE HOLE, THE SLEEVE IS KEPT IN THE HOLD BY THE APPARATUS SO THAT RADIALLY OUTWARDS DIRECTED FORCES ARE EXERTED BY THE PLUG ON THE SLEEVE, WHICH IN TURN TRANSMITS THE COLDWORKING FORCES TO THE WALL OF THE HOLE. AFTER THE PLUG IS PULLED OUT OF THE HOLE, THE SLEEVE IS REMOVED FROM THE HOLE AND DISCARDED.
