Tandem interlacing textile jet nozzle assembly

Image Number 4 for United States Patent #6868593.

An apparatus and method for improving multifilament textile yarn interlacing includes two spaced apart interlacing jet nozzles 2a and 2b positioned so that the yarn channels 4a and 4b of the two nozzles are aligned in a tandem relationship. High pressure air is injected into an upstream nozzle 2a with a velocity component tending to entrain or advance the yarn through the upstream nozzle 2a. High pressure air is injected into the downstream nozzle 2b with a velocity component tending to retard passage of the yarn through the downstream nozzle 2b.
