Abstract
A method and apparatus for controlling a false twist texturing machine, which extends the previously known process for controlling operation during the normal operation of the machine, to exceptional operating conditions, such as during yarn thread-up and/or restarting after a temporary stoppage of operation by reason of a power failure. In accordance with the invention, the known method which includes control of the frictional force imparted to the yarn as a function of the yarn tension, is modified in such a manner that during periods other than normal operation, the control of the frictional force as a function of the yarn tension is terminated, and a predetermined frictional force is imparted to the yarn.
