DEVICE AND METHOD FOR MEASURING PARALLELISM AND ALIGNMENT OF ROLLS

摘要

The invention relates to a measuring device and optionally to a correspondingadapter that facilitate a quantitative measurement of parallelism andalignment of rolls. Said measuring device is mounted on the front ends of saidrolls. A specific embodiment relates to a projection device for emitting alight beam or a fan of light. The light beams emitted by said projectiondevice are incident on a high-precision reception device. The reception deviceis also mounted on a front end of the roll.
