Measuring with zero back-tension

Working principle:

Umlauf Bridles push the strip out of the processing line, allowing it to move over the run-out roller table in a tension-free and undisturbed condition. Thus Umlauf Bridles create ideal conditions for optical flatness measurements.
 

Benefits:

Precise flatness measurement

The strip lies flat on the run-out roller table, allowing for highly precise optical flatness measurement.
