ABSTRACT:
A spoked wheel truing machine is provided with a tool that is capable of clamping the shank of each spoke nipple and rotating it an integral number of revolutions. The particular direction of rotation of the clamping tool is determined by top and bottom limit switches along with left and right limit switches. A drive motor is used to rotate the spoked wheel about its axle and is provided with an automatic brake that maintains the position of the wheel when the motor is de-energized. The clamping tool is rotated into position around the nipple's shank when a signal is received indicating that a nipple is in an operative position and the rim proximate that nipple is axially misaligned. The truing apparatus also comprises a means for supporting the spoked wheel by its central axle in a position that disposes the axle in a horizontal plane. The truing apparatus aligns the radius of the rim in a preferred reference circle and aligns the rim in a vertical plane that intersects the hub of the wheel midway between its flanges.
