摘要： A straight rod is automatically positioned at the center of a mandrel of a U-bolt bending machine for subsequent bending into a U-bolt by the bending machine. The rod is positioned between spaced centering plates of a centering device mounted to the machine. The centering plates are coupled to a transport mechanism of the centering device that automatically provides for conjoint oppositely directed movement of the centering plates to automatically center and position the centerline of the rod at the centerline of the machine without marking or measuring the rod or other tasks previously required to accurately position the rod.
