ABSTRACT:
A system for aligning a plurality of cylindrical rollers is disclosed. The system comprising a light emitter unit having a horizontal planar light source for generating a horizontal planar light signal and a vertical planar light source for generating a vertical planar light signal. The system further comprising a reflector unit having a reflective surface for receiving the vertical light signal from the light emitter unit and returning a reflected vertical light signal. A horizontal lineal indicator is provided on the exterior surface of the reflector unit and a vertical lineal indicator is provided on the exterior surface of the light emitter unit. By aligning the horizontal planar light signal with the horizontal lineal indicator and by aligning the reflected vertical light signal with the vertical lineal indicator, the cylindrical rollers are aligned in a common plane and are substantially parallel to each other.
