Industrial

Loepfe, the manufacturer of sensors and monitoring equipment for yarn spinning and fabric weaving processes, has developed FALCON-i sensor that can be installed before or after a weft feeder in order to monitor an individual thread for finest knots, fluff, filamentation, smallest thick places or even capillary breaks.

The thread can be monitored by using sensitivity levels, to be set manually or automatically. When contamination caused by knots, fluff and filamentation is severe, the sensor can also be installed upside down, which allows most reliable and constant monitoring, the company reports.

Measurement reliability

The thread is guided virtually contact-free through the optical measuring field by yarn guides before and after the sensor and a stop is triggered for defined faults. The colour 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 yarns in any material composition, can be processed. Conductive materials can also be processed without restriction. The housing of the sensor is made from shielding material so that any existing static or electromagnetic fields will not affect measurement reliability.

FALCON-i sensor

The FALCON-i sensor is microprocessor-controlled, providing many options for connection to evaluation modules. Adaptations of the software and individual adaptations to customer requirements can be easily implemented through software upgrades of already available sensors.

Loepfe is a leader in manufacturing optical yarn clearers for automatic winding machines. Many years of experience in this field enabled the development of the new optical FALCON-I sensor.

The company’s new yarn defect sensor FALCON-i is not only complementing the various available knotless weaving concepts, but can be used in many different processes down the textile production chain.
