摘要： 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.

摘要： The yarn is formed into a loop and a loop sensor monitors the variations in length in the loop of yarn. The variations in the size of the loop result from a difference in the speed between the speed of the yarn and the speed of the draw-off or delivery member. The draw-off or delivery member is driven by an asynchronous motor having a slip-clutch drive with an assembly for braking in response to eddy currents. In particular, a disc is connected to the motor and a magnetic field is applied to the disc, the magnitude of the field which is applied to the disc directly dependent upon the size of the loop. In the preferred embodiment, the regulation of the speed of a pilot roller of a winder as a function of the delivery speed of the yarn is accomplished.
