The INCA jet unit is a new and patented interlacing system for BCF yarns. It generates the tangle knots by a non-continuous air impulse. The jet inserts are fixed radial on a rotor unit in a tandem arrangement. The compressed air stream is put across the holes of the rotor unit to the jet inserts and generates alternately a pulsating air flow. This leads to an excellent interlacing performance.

Advantages compared to conventional systems:

• compared to conventional tandem systems air savings of more than 50% possible
• Regularity of the composed tangle knots
• Uniformity on strong as well as on weak interlaced knots
• compact design, integrated motor drive
• Long life time
• easy and quick exchange of nozzle inserts
