RollAlign™ Laser System Aids Accurate Visual Alignment

Miami-based Ludeca Inc. now offers RollAlign, a laser roll alignment system that facilitates
accurate visual alignment of process rolls during replacement operations. A Laser Emitter unit
mounted to a stationary roll transmits two Class 2 fanned 635-nanometer laser lines to a Reflector
unit positioned on the roll to be moved. The operator then is able to view both the vertical and
horizontal angles and accurately adjust the roll into parallel alignment.

RollAlign is suitable for aligning rolls of most diameters that are spaced 0.5 inch to 10
feet apart. It also can be used to align and measure crowned rolls.
