Abstract

Apparatus and methods for aligning rolls, wherein a first structure, for being associated with a first roll, and a second structure, for being associated with a second roll are provided. A laser is associated with one of the two structures and a target is associated with the other of the two structures. The two structures, the laser and the target are adapted to indicate whether the two rolls exhibit an aligned condition with respect to one another. Also contemplated is a calibration unit for calibrating an alignment device, wherein the unit itself includes two model rolls.
