OPTICAL PRECISION

OPTICAL PRECISION

Loepfe invented the optoelectronic yarn clearers. The optical yarn control system is the most reliable and commonly used measuring principle worldwide. Optics, electronics, and software are the foundation of a precise and constant yarn quality control. 


The outstanding advantages of an optical measuring principle are, that neither humidity, climatic changes nor the material to be checked, influence the measurement. Today, Loepfe is the worldwide leading manufacturer and solution partner for optoelectronic online quality assurance systems. Machine manufacturers, as well as spinning mills around the globe, use Loepfe technology from Switzerland. They know what to expect: Innovation at top level, quality made in Switzerland.

OPTICAL INSPECTION BY HUMAN EYE

Despite many high-tech methods, the qualitative assessment of the finished surface is always done with the human eye. Woven and knitted fabrics are judged on their appearance, wherein even surface texture and uniform color are clear signs of quality. A result that can only be achieved by a constant yarn quality control.

MASTER YOUR DAILY CHALLENGES

The optical measurement delivers precise and constant  results unaffected by the daily challenges in a spinning mill such as:

  • changing ambient conditions
  • hairiness
  • twist variations
  • various materials 
  • any splicing systems
  • contaminations
  • foreign matter
  • shade variations
  • preparation and process faults
