Abstract

This invention relates to a device for the transfer and the treatment of textile yarns comprising a pneumatic means comprising a body pierced from top to bottom with a channel of transversal section, preferably oblong the surface of said body increasing from upstream to downstream, said body being slit in the forepart to make the channel communicate with the outside on substantially its whole length along the generatrix of channel, and a higher part provided with at least a tubular member allowing a fluid to be fed to at least two orifices, parallel to the axis of the nozzle channel, said tubular members communicating with the higher part of said channel by means of a chamber, and a slot for permitting the passage of yarn from the outside towards said channel.
