USTER's latest computer-aided yarn clearing system

摘要

The target with clearing limits for yarn clearers is to remove disturbing faults (outliers) without touching frequently-occurring events, which is defined as the 'yarn body'. These frequently occurring events do not represent faults and therefore normally do not have to be cut. Conventional clearers used the so-called "class clearing" and/or "channel clearing" to reach this objective. Both methods are less effective since they could either leave disturbing faults in or result in too many unjustified cuts mainly because the yarn body was difficult to monitor and display.
