Abstract
Abstract A device for immovably holding a rod during a machining operation comprises means for forming surface contours on the rod before the rod is advanced through a machining zone and a movable profiled surface coacting with the surface contours on the rod to releasably hold the rod in place during the machining operation. A plurality of reciprocating holding members cooperate together to immovably hold the contoured rod against the profiled surface during the machining operation.
