Method and device for producing a crimped multifilament thread

A device for manufacturing a crimped multifilament thread comprising:

• a spinning apparatus;
• a stretching apparatus downstream of the spinning apparatus;
• a crimping apparatus downstream of the spinning apparatus;
• a treatment apparatus downstream of the spinning apparatus for producing an intertwined knot, wherein the treatment apparatus is arranged in a thread track between two driven godets;
• the treatment apparatus including a controllable blowing apparatus that has a rotationally driven nozzle ring with a peripheral thread guide track and at lease one nozzle bore opening into the thread guide track, which is periodically connected with a compressed air source by rotation of the nozzle ring for periodically producing a compressed air pulse directed on the thread;
• an enclosure having a thread inlet and a thread outlet with the enclosure being arranged at a front side of a support wall and completely surrounding the nozzle ring to enclose the nozzle ring;
• and
• an electric motor associated with the nozzle ring, wherein a back side of the support wall supports the motor.
