ABSTRACT:
A yarn false twist texturing process and apparatus wherein the tension of the advancing yarn is monitored. The resulting signal is processed through a time filter to produce a time averaged signal, and the time averaged signal is compared with a set point signal to produce an adjusting signal which acts to control the false twisting unit so as to provide a substantially constant tension. The adjusting signal is also used to detect deficiencies of the false twisting process which disturb the uniformity of the texturing process.
