False twist texturing apparatus

In a machine for the false twist texturing of textile threads in a plurality of side-by-side thread treating positions including two upstanding, spaced support frames positioned in facing relation, an operator walkway at the bottom of and extending between the frames to permit access to the thread treating positions, one of the frames supporting thread supply means in a lower portion thereof and thread take-up means in an upper portion thereof and the other frame supporting thread heaters and false twist spindles for treating the threads, and each of the thread treating positions having a thread path extending between the thread supply and take-up means being defined by a first thread advancing means positioned in a lower portion of the other frame for receiving thread from said thread supply means, a first thread heater positioned above said first thread advancing means and supported on said other support frame, a false twist spindle positioned above said first heater, second thread advancing means positioned above said spindle, a second thread heater positioned above said second thread advancing means and having a substantially straight heating tube for passage of the thread, the heating tube having an inlet for the thread adjacent the level of the head of an operator for receiving thread from said second advancing means and an outlet in an upper portion of said other frame above the head of an operator for exit of the thread from the heating tube, and third thread advancing means positioned above said outlet and situated generally on an extension of the longitudinal axis of the tube;

• the improvement therewith comprising pneumatic means for transporting the thread from the second thread advancing eans, through the tube of the second heating means, through the third thread advancing means and to the vicinity of the thread take-up means, said pneumatic means including a pneumatic transportation tube extending across the walkway and having a thread-receiving mouthpiece situated above and in proximity to said third thread advancing means for receiving a thread therefrom and a thread outlet positioned adjacent said thread take-up means.
