In order to monitor an individual thread for finest knots, fluff, filamentation, smallest thick places or even capillary breaks, Loepfe’s newly developed FALCON-i sensor is installed, e.g., before or after a weft feeder.
The thread to be monitored can be monitored with different sensitivity levels, which can be set manually or automatically. Automatic mode determines the sensitivity level itself. The sensor is insensitive to vibrations, which can be extremely disturbing, especially with laser measuring devices, and which could cause false stops. When contamination is severe, the sensor can also be installed «upside down» which allows most reliable and constant monitoring. The thread to be monitored is guided through the optical measuring field by yarn guides before and after the sensor virtually contact-free, and a stop is triggered for defined faults. The color of the thread to be monitored also has no influence on measurement reliability. It is therefore possible to monitor the latest high-tech materials, e.g. carbon, without problems with FALCON-i. Monofilaments, multifilaments as well as spun
