Reliable NSLT fault detection: Loepfe's proficient optical yarn clearer ensures reliable results under any production condition. With steady output, spinning mills become dependable partners in the production chain. The system reliably detects spinning process-related faults (NSLT) and provides detailed classification reports.

Precise off-standard alarms: Effective and precise detection of OffStandard bobbins is an important function for spinning mills. It saves time and money and ensures the yarn quality level.

Secure count monitoring: Accurate count monitoring with the proficient optical sensor. The unique Loepfe technology allows for precise monitoring of yarn diameter, enabling effective control of count deviations.

Secure hairiness detection & unaffected by humidity: The Loepfe optical infrared sensor offers a notable advantage: it remains unaffected by humidity, climatic changes, or the material being inspected. As the established leader in hairiness detection, the optical infrared sensor is highly reliable.

For all splicer types: All Loepfe winding yarn clearers include a splice accumulation feature, designed to enhance productivity and efficiency. This feature remains active after each cut for 25 meters. Moreover, the ZENIT+ system is versatile and compatible with all splicer types, allowing the user to choose what suits their specific needs.

Detection of colored foreign matter in dyed yarn: Foreign matter of any color and material can be accurately detected. This includes identifying colored foreign matter in raw white and dyed yarn. Additionally, the system is capable of detecting and eliminating even the smallest shade variations. To achieve this, the yarn is illuminated from multiple angles to detect any faults.

Elimination of smallest shade variations: The OffColor (Option) feature is able to detect and eliminate very small color and shade variations in the yarn during the winding process.

P-Sensor:  The invisible becomes visible with the triboelectric P sensor

  • Detection of raw white and transparent polypropylene
  • Detection of white PP faults in blended cotton yarn 
  • Detection of even the finest synthetic foreign matter

While the yarn passes the P sensor, the fibers exchange electrons with the sensor. This effect is referred to as the „triboelectric effect“. When a synthetic fiber passes the electrode of the sensor, it is detected because of the triboelectric charge difference.
