Abstract: A machine is provided for testing the straightness of arrows, for localizing and measuring any want of straightness, and for mechanically correcting any defect of this nature that may be discovered. The machine desirably includes a central stand on which a deflection meter is mounted, together with a straightening lever. A trackway in the form of spaced, parallel horizontal bars is provided. Arrow supporting and rotating carriages are mounted on the trackway with freedom for independent adjustment toward and from the central stand. Each carriage includes two side by side rollers and means for operating the rollers in unison to turn an arrow engaged by the meter and to sustain the arrow during straightening.
