Abstract
A machine is disclosed which will test an elongated round cross-section workpiece by bending the workpiece as it is rotated to determine if a breakable area such as a welded area will break. Broken workpieces are discarded but those testing satisfactorily proceed through the machine for a straightening operation to straighten the entire workpiece, including the breakable area. The above description is merely one form of the invention and is not to be construed as limiting on the scope of the invention.
